Unmanned Aerospace Vehicle Workshop  

SciTech Connect

The Unmanned Aerospace Vehicle (UAV) Workshop concentrated on reviewing and refining the science experiments planned for the UAV Demonstration Flights (UDF) scheduled at the Oklahoma Cloud and Radiation Testbed (CART) in April 1994. These experiments were focused around the following sets of parameters: Clear sky, daylight; Clear-sky, night-to-day transition; Clear sky - improve/validate the accuracy of radiative fluxes derived from satellite-based measurements; Daylight, clouds of opportunity; and, Daylight, broken clouds.

UAVs in climate research: The ARM Unmanned Aerospace Vehicle Program  

SciTech Connect

In the last year, a Department of Energy/Strategic Environmental Research and Development Program project known as ``ARM-UAV`` has made important progress in developing and demonstrating the utility of unmanned aerospace vehicles as platforms for scientific measurements. Recent accomplishments include a series of flights using an atmospheric research payload carried by a General Atomics Gnat UAV at Edwards AFB, California, and over ground instruments located in north-central Oklahoma. The reminder of this discussion will provide background on the program and describe the recent flights.

Atmospheric radiation measurement unmanned aerospace vehicle (ARM-UAV) program  

SciTech Connect

ARM-UAV is part of the multi-agency U.S. Global Change Research Program and is addressing the largest source of uncertainty in predicting climatic response: the interaction of clouds and the sun`s energy in the Earth`s atmosphere. An important aspect of the program is the use of unmanned aerospace vehicles (UAVs) as the primary airborne platform. The ARM-UAV Program has completed two major flight series: The first series conducted in April, 1994, using an existing UAV (the General Atomics Gnat 750) consisted of eight highly successful flights at the DOE climate site in Oklahoma. The second series conducted in September/October, 1995, using two piloted aircraft (Egrett and Twin Otter), featured simultaneous measurements above and below clouds and in clear sky. Additional flight series are planned to continue study of the cloudy and clear sky energy budget in the Spring and Fall of 1996 over the DOE climate site in Oklahoma. 3 refs., 4 figs., 1 tab.

Atmospheric Radiation Measurement Program - unmanned aerospace vehicle: The follow-on phase  

SciTech Connect

Unmanned Aerospace Vehicle (UAV) demonstration flights (UDF) are designed to provide an early demonstration of the scientific utility of UAVs by using an existing UAV and instruments to measure broadband radiative flux profiles under clear sky conditions. UDF is but the first of three phases of ARM-UAV. The second phase significantly extends both the UAV measurement techniques and the available instrumentation to allow both multi-UAV measurements in cloudy skies and extended duration measurements in the tropopause. These activities build naturally to the third and final phase, that of full operational capability, i.e., UAVs capable of autonomous operations at 20-km altitudes for multiple days with a full suite of instrumentation for measuring radiative flux, cloud properties, and water vapor profiles.

The ARM unpiloted aerospace vehicle (UAV) program  

SciTech Connect

Unmanned aerospace vehicles (UAVs) are an important complement to the DOE`s Atmospheric Radiation Measurement (ARM) Program. ARM is primarily a ground-based program designed to extensively quantify the radiometric and meteorological properties of an atmospheric column. There is a need for airborne measurements of radiative profiles, especially flux at the tropopause, cloud properties, and upper troposphere water vapor. There is also a need for multi-day measurements at the tropopause; for example, in the tropics, at 20 km for over 24 hours. UAVs offer the greatest potential for long endurance at high altitudes and may be less expensive than piloted flights. 2 figs.

Geophex Airborne Unmanned Survey System  

SciTech Connect

Ground-based surveys place personnel at risk due to the proximity of buried unexploded ordnance (UXO) items or by exposure to radioactive materials and hazardous chemicals. The purpose of this effort is to design, construct, and evaluate a portable, remotely-piloted, airborne, geophysical survey system. This non-intrusive system will provide stand-off capability to conduct surveys and detect buried objects, structures, and conditions of interest at hazardous locations. During a survey, the operators remain remote from, but within visual distance of, the site. The sensor system never contacts the Earth, but can be positioned near the ground so that weak geophysical anomalies can be detected. The Geophex Airborne Unmanned Survey System (GAUSS) is designed to detect and locate small-scale anomalies at hazardous sites using magnetic and electromagnetic survey techniques. The system consists of a remotely-piloted, radio-controlled, model helicopter (RCH) with flight computer, light-weight geophysical sensors, an electronic positioning system, a data telemetry system, and a computer base-station. The report describes GAUSS and its test results.

Solar-powered unmanned aerial vehicles  

SciTech Connect

An analysis was performed to determine the impact of various power system components and mission requirements on the size of solar-powered high altitude long endurance (HALE)-type aircraft. The HALE unmanned aerial vehicle (UAV) has good potential for use in many military and civil applications. The primary power system components considered in this study were photovoltaic (PV) modules for power generation and regenerative fuel cells for energy storage. The impact of relevant component performance on UAV size and capability were considered; including PV module efficiency and mass, power electronics efficiency, and fuel cell specific energy. Mission parameters such as time of year, flight altitude, flight latitude, and payload mass and power were also varied to determine impact on UAV size. The aircraft analysis method used determines the required aircraft wing aspect ratio, wing area, and total mass based on maximum endurance or minimum required power calculations. The results indicate that the capacity of the energy storage system employed, fuel cells in this analysis, greatly impacts aircraft size, whereas the impact of PV module efficiency and mass is much less important. It was concluded that an energy storage specific energy (total system) of 250--500 Whr/kg is required to enable most useful missions, and that PV cells with efficiencies greater than {approximately} 12% are suitable for use.

VOC reduction strategies for the aerospace industry  

SciTech Connect

The aerospace NESHAP, which was issued on September 1, 1995, requires reductions in Volatile Organic Compounds (VOCs) and organic Hazardous Air Pollutant (HAP) emissions associated with the application of primer and topcoat. The regulation affects any facility that is a major source of HAPs and produces, reworks, or repairs, in any amount any commercial, civil, or military aerospace vehicle. Options for reducing VOC and organic HAP emissions include use of low VOC/organic HAP containing coatings or implementation of air pollution control systems. Use of primers and topcoats that meet the regulatory limits for VOC and organic HAP content is clearly the lowest cost option of meeting requirements of the aerospace NESHAP. However, some facilities have been unsuccessful in identifying aerospace paints and primers that meet requirements of the NESHAP and also have acceptable performance properties. For those aerospace companies considering implementation of air pollution control systems, several strategies can help to reduce the anticipated capital and operating costs. Such strategies include: segregation of specialty coatings, non-aerospace coatings, and low-use coatings not affected by the aerospace NESHAP from regulated paints and primers; reduction of airflows in affected booths; recirculation of air; and combination of exhausts from one or more booth. Estimated capital and operating costs are also provided for the air pollution control systems best suited for aircraft painting and priming operations. These systems include regenerative thermal oxidizers and fluidized bed/rotary concentrators in conjunction with thermal oxidizers. Even after implementing strategies to reduce VOC and organic HAP pollution control system costs, economics will dictate use of compliant primers and topcoats for many aerospace companies. 6 refs.

Potential and prospective implementation of carbon nanotubes on next generation aircraft and space vehicles: A review of current and expected applications in aerospace sciences  

Science Journals Connector (OSTI)

Abstract Carbon nanotubes have instigated the interest of many different scientific fields since their authenticated introduction, more than two decades ago. Particularly in aerospace applications, the potential implementations of these advanced materials have been predicted to have a large impact on future aircraft and space vehicles, mainly due to their distinct features, which include superior mechanical, thermal and electrical properties. This article provides the very first consolidated review of the imminent prospects of utilizing carbon nanotubes and nanoparticles in aerospace sciences, based on their recent implementations and predicted future applications. Explicitly, expected carbon nanotube employment in aeronautics and astronautics are identified for commercial aircraft, military aircraft, rotorcraft, unmanned aerial vehicles, satellites, and space launch vehicles. Attention is devoted to future utilization of carbon nanotubes, which may comprise hydrogen storage encapsulation, composite material implementation, lightning protection for aircraft, aircraft icing mitigation, reduced weight of airframes/satellites, and alleviation of challenges related to future space launch. This study further sheds light onto recent actualized implementations of carbon nanotubes in aerospace applications, as well as current and prospective challenges related to their usage in aerospace sciences, encompassing health and safety hazards, large scale manufacturing, achievement of optimum properties, recycling, and environmental impacts.

Aerospace NESHAP: A collaborative approach to implementation  

SciTech Connect

The purpose of the Aerospace National Emission Standard for Hazardous Air Pollutants (NESHAP) is to minimize emissions of hazardous air pollutants (HAPs) and volatile organic compounds (VOCs) from major sources who manufacture or rework aerospace vehicles or components. The NESHAP requires emission reductions through implementation of work practices, application of slower evaporating solvents and coatings with low-HAP and low-VOC content, usage of high transfer efficiency spray equipment, and installation of high capture efficiency exhaust filtration for coatings containing metals. The rule also requires extensive monitoring, recordkeeping, and self-reporting to track compliance. For existing sources the rule becomes effective September 1,1998. Over the past year the Puget Sound Air Pollution Control Agency (PSAPCA) has worked with the Boeing Company and EPA to identify the requirements of the aerospace NESHAP, understand what it means in everyday practice, and develop an enforcement strategy for ensuring compliance. A workshop was held with aerospace manufacturers, local regulators, and EPA to discuss implementation of the rule. Issues regarding compliance efforts and determinations were openly discussed. Subsequent to the workshop, PSAPCA and the Boeing Company participated in several mock inspections to review facility compliance efforts before the rule became effective. Collaborative efforts also ensued to develop operating permit monitoring requirements. Aerospace NESHAP requirements were incorporated into these permits. There are still questions regarding compliance determinations that must be further discussed and resolved. But by using the collaborative approach and having regulators and sources working together, there is a process to work out answers and approaches that will lead to an increased mutual understanding of the aerospace NESHAP and eventual compliance with the standard.

Mapping infectious disease landscapes: unmanned aerial vehicles and epidemiology  

Science Journals Connector (OSTI)

The potential applications of unmanned aerial vehicles (UAVs), or drones, have generated intense interest across many fields. \\{UAVs\\} offer the potential to collect detailed spatial information in real time at relatively low cost and are being used increasingly in conservation and ecological research. Within infectious disease epidemiology and public health research, \\{UAVs\\} can provide spatially and temporally accurate data critical to understanding the linkages between disease transmission and environmental factors. Using \\{UAVs\\} avoids many of the limitations associated with satellite data (e.g., long repeat times, cloud contamination, low spatial resolution). However, the practicalities of using \\{UAVs\\} for field research limit their use to specific applications and settings. \\{UAVs\\} fill a niche but do not replace existing remote-sensing methods.

New AB-Thermonuclear Reactor for Aerospace  

E-Print Network (OSTI)

There are two main methods of nulcear fusion: inertial confinement fusion (ICF) and magnetic confinement fusion (MCF). Existing thermonuclear reactors are very complex, expensive, large, and heavy. They cannot achieve the Lawson creterion. The author offers an innovation. ICF has on the inside surface of the shell-shaped combustion chamber a covering of small Prism Reflectors (PR) and plasma reflector. These prism reflectors have a noteworthy advantage, in comparison with conventional mirror and especially with conventional shell: they multi-reflect the heat and laser radiation exactly back into collision with the fuel target capsule (pellet). The plasma reflector reflects the Bremsstrahlung radiation. The offered innovation decreases radiation losses, creates significant radiation pressure and increases the reaction time. The Lawson criterion increases by hundreds of times. The size, cost, and weight of a typical installation will decrease by tens of times. The author is researching the efficiency of these innovations. Keywords: Thermonuclear reactor, Multi-reflex AB-thermonuclear reactor, aerospace thermonuclear engine.

Unmanned airships for near earth remote sensing missions  

SciTech Connect

In recent years the study of Earth processes has increased significantly. Conventional aircraft have been employed to a large extent in gathering much of this information. However, with this expansion of research has come the need to investigate and measure phenomena that occur beyond the performance capabilities of conventional aircraft. Where long dwell times or observations at very low attitudes are required there are few platforms that can operate safely, efficiently, and cost-effectively. One type of aircraft that meets all three parameters is the unmanned, autonomously operated airship. The UAV airship is smaller than manned airships but has similar performance characteristics. It`s low speed stability permits high resolution observations and provides a low vibration environment for motion sensitive instruments. Maximum airspeed is usually 30mph to 35mph and endurance can be as high as 36 hours. With scientific payload capacities of 100 kilos and more, the UAV airship offers a unique opportunity for carrying significant instrument loads for protracted periods at the air/surface interface. The US Army has operated UAV airships for several years conducting border surveillance and monitoring, environmental surveys, and detection and mapping of unexploded ordinance. The technical details of UAV airships, their performance, and the potential of such platforms for more advanced research roles will be presented. 3 refs., 5 figs.

Photovoltaic electric power applied to Unmanned Aerial Vehicles (UAV)  

SciTech Connect

Photovoltaic electric-powered flight is receiving a great deal of attention in the context of the United States` Unmanned Aerial Vehicle (UAV) program. This paper addresses some of the enabling technical areas and their potential solutions. Of particular interest are the long-duration, high-altitude class of UAV`s whose mission it is to achieve altitudes between 60,000 and 100,000 feet, and to remain at those altitudes for prolonged periods performing various mapping and surveillance activities. Addressed herein are studies which reveal the need for extremely light-weight and efficient solar cells, high-efficiency electric motor-driven propeller modules, and power management and distribution control elements. Since the potential payloads vary dramatically in their power consumption and duty cycles, a typical load profile has been selected to provide commonality for the propulsion power comparisons. Since missions vary widely with respect to ground coverage requirements, from repeated orbiting over a localized target to long-distance routes over irregular terrain, the authors have also averaged the power requirements for on-board guidance and control power, as well as ground control and communication link utilization. In the context of the national technology reinvestment program, wherever possible they modeled components and materials which have been qualified for space and defense applications, yet are compatible with civilian UAV activities. These include, but are not limited to, solar cell developments, electric storage technology for diurnal operation, local and ground communications, power management and distribution, and control servo design. And finally, the results of tests conducted by Wright Laboratory on ultralight, highly efficient MOCVD GaAs solar cells purchased from EPI Materials Ltd. (EML) of the UK are presented. These cells were also used for modeling the flight characteristics of UAV aircraft.

Evaluation of Bare Ground on Rangelands using Unmanned Aerial Vehicles  

SciTech Connect

Attention is currently being given to methods that assess the ecological condition of rangelands throughout the United States. There are a number of different indicators that assess ecological condition of rangelands. Bare Ground is being considered by a number of agencies and resource specialists as a lead indicator that can be evaluated over a broad area. Traditional methods of measuring bare ground rely on field technicians collecting data along a line transect or from a plot. Unmanned aerial vehicles (UAVs) provide an alternative to collecting field data, can monitor a large area in a relative short period of time, and in many cases can enhance safety and time required to collect data. In this study, both fixed wing and helicopter UAVs were used to measure bare ground in a sagebrush steppe ecosystem. The data were collected with digital imagery and read using the image analysis software SamplePoint. The approach was tested over seven different plots and compared against traditional field methods to evaluate accuracy for assessing bare ground. The field plots were located on the Idaho National Laboratory (INL) site west of Idaho Falls, Idaho in locations where there is very little disturbance by humans and the area is grazed only by wildlife. The comparison of fixed-wing and helicopter UAV technology against field estimates shows good agreement for the measurement of bare ground. This study shows that if a high degree of detail and data accuracy is desired, then a helicopter UAV may be a good platform. If the data collection objective is to assess broad-scale landscape level changes, then the collection of imagery with a fixed-wing system is probably more appropriate.

Bayesian Hierarchical Models for aerospace gas turbine engine prognostics  

Science Journals Connector (OSTI)

Abstract Improved prognostics is an emerging requirement for modern health monitoring that aims to increase the fidelity of failure-time predictions by the appropriate use of sensory and reliability information. In the aerospace industry, it is a key technology to maximise aircraft availability, offering a route to increase time in-service and to reduce operational disruption through improved asset management. An aircraft engine is a complex system comprising multiple subsystems that have dependent interactions so it is difficult to construct a model of its degradation dynamics based on physical principles. This complexity suggests that a statistically robust methodology for handling large quantities of real-time data would be more appropriate. In this work, therefore, a Bayesian approach is taken to exploit fleet-wide data from multiple assets to perform probabilistic estimation of remaining useful life for civil aerospace gas turbine engines. The paper establishes a Bayesian Hierarchical Model to perform inference and inform a probabilistic model of remaining useful life. Its performance is compared with that of an existing Bayesian non-Hierarchical Model and is found to be superior in typical (heterogeneous) scenarios. The techniques use Bayesian methods to combine two sources of information: historical in-service data across the engine fleet and once per-flight transmitted performance measurement from the engine(s) under prognosis. The proposed technique provides predictive results within well defined uncertainty bounds and demonstrates several advantages of the hierarchical variants ability to integrate multiple unit data to address realistic prognostic challenges. This is illustrated by an example from a civil aerospace gas turbine fleet data.

Acquisitions and alliances in the aerospace industry: an unusual triad  

Science Journals Connector (OSTI)

The two primary sectors of the aerospace industry, commercial and military aviation, are each dominated by two key firms Airbus Industrie and Boeing in the commercial sector, and Lockheed Martin and Boeing in the military sector. This unique triad offers an opportunity for examining how technology acquisition and business development are pursued under such circumstances. The paper shows that alliances are utilised by both major players in commercial aviation, while acquisitions are the principal strategies selected in the military aviation industry. Boeing appears to shift its strategic choices appropriately by industry to match its competitors as well as to correspond to the approach advocated by related technology strategy literature.

Abstract: In this chapter we shall attempt to provide the reader with an understanding of what MEMS (micro-electromechanical systems) is and how it has become an enabling technology for some harsh environment aerospace applications, how it can contribute significantly to enhancing existing and future aerospace systems. We will explain what is meant by a harsh environment and how the engineer/scientist would need to accommodate his/her design to perform in this domain. Conveying this is perhaps best accomplished by presenting selected case studies, engineering examples of selected MEMS systems designed specifically for harsh environments in aerospace applications.

Quest for a novel force: a possible revolution in aerospace  

Science Journals Connector (OSTI)

Conventional understanding of flight in aerospace depends primarily on the application of Newton's laws in the design of components providing propulsive and lifting forces. This reality has given incredible advances in capability during nearly a century of endeavour. But this century of achievement was preceded by millennia of speculation, literary fantasies, some tentative scientific proposals and brave practical attempts of how manned flight might be attained. However, the coming of reality did not stop the aerial speculation which has continued over the last century with various doubtful claims that have disguised an underlying seriousness seeking for alternative means of accomplishing aeronautical ambitions. Recently, three professional programmes have emerged, directed to discovering such new ways of propulsion, viz., the NASA Breakthrough Propulsion Physics programme, the BAE SYSTEMS Project Greenglow and work at ESA. The author has followed these novel developments for over half a century and is now a consultant to the BAE SYSTEMS programme. BAE SYSTEMS monitors many evolving scientific and technical advances to seek competitive advantages for its products and pays appropriate attention to the most promising solutions. Some of these are correctly described as breakthroughs and in the speculative field of advanced propulsion it seeks advice on the truth or falsehood of the many quantitative claims that have been published. The primary task is to design radically new aeronautical systems based on new physical principles. This paper sets out this strategy which has the following logic: to account for previous claims, patents and investigations and assess their validity, make scientific experiments of new phenomena and generate theories, propose radically new ways (engines) of providing aeronautical forces, assess whether any of these imaginary engines could improve aerospace performance, if so, how significant would the improvement be? it appears that one solution offers superb improvement, globally, for over a century ahead, hence, it is well worth the effort to realise this in practice, one of the proposed engines is in sequence with previous transport systems, the best way forward is serendipitous collaboration with advanced thinkers in physics, and Project Greenglow links new physics with novel engines and global transport performance by means of evolving techniques used in novel ways This process, described in this paper, is essentially project-led research (sometimes called focussed search), in which theoretical possibilities are subjected to the classical process of conjecture and refutation, also employed in a previous paper published in this journal, viz., Global issues affecting aeronautics (Prog. Aerosp. Sci. 1999; 35: 413). There is an important distinction between the UK programme and others, i.e., the inclusion of aeronautics as well as spaceflight, whereas the others deal exclusively with spaceflight.

Aerial radiation monitoring around the Fukushima Dai-ichi nuclear power plant using an unmanned helicopter  

Science Journals Connector (OSTI)

Abstract The Great East Japan Earthquake on March 11, 2011 generated a series of large tsunami that seriously damaged the Fukushima Dai-ichi Nuclear Power Plant (FDNPP), which resulted in the release of radioactive materials into the environment. To provide further details regarding the distribution of air dose rate and the distribution of radioactive cesium (134Cs and 137Cs) deposition on the ground within a radius of approximately 5km from the nuclear power plant, we carried out measurements using an unmanned helicopter equipped with a radiation detection system. The distribution of the air dose rate at a height of 1m above the ground and the radioactive cesium deposition on the ground was calculated. Accordingly, the footprint of radioactive plumes that extended from the FDNPP was illustrated.

Unmanned Aerial Vehicles (UAV) are being proposed for many applications including surveillance, mapping and atmospheric studies. These applications require a lightweight, low speed, medium to long duration airplane. Due to the weight, speed, and altitude constraints imposed on such aircraft, solar array generated electric power is a viable alternative to air-breathing engines. Development of such aircraft is currently being funded under the Environmental Research Aircraft and Sensor Technology (ERAST) program. NASA Lewis Research Center (LeRC) is currently building a Solar Electric Airplane to demonstrate UAV technology. This aircraft utilizes high efficiency Applied Solar Energy Corporation (ASEC) GaAs/Ge space solar cells. The cells have been provided by the Air Force through the ManTech Office. Expected completion of the plane is early 1995, with the airplane currently undergoing flight testing using battery power.

Implementation of an Onboard Visual Tracking System with Small Unmanned Aerial Vehicle (UAV)  

E-Print Network (OSTI)

This paper presents a visual tracking system that is capable or running real time on-board a small UAV (Unmanned Aerial Vehicle). The tracking system is computationally efficient and invariant to lighting changes and rotation of the object or the camera. Detection and tracking is autonomously carried out on the payload computer and there are two different methods for creation of the image patches. The first method starts detecting and tracking using a stored image patch created prior to flight with previous flight data. The second method allows the operator on the ground to select the interest object for the UAV to track. The tracking system is capable of re-detecting the object of interest in the events of tracking failure. Performance of the tracking system was verified both in the lab and during actual flights of the UAV. Results show that the system can run on-board and track a diverse set of objects in real time.

Catalytic pressurization of liquid hydrogen fuel tanks for unmanned aerial vehicles  

Science Journals Connector (OSTI)

As the use and applications of Unmanned Aerial Vehicles (UAV) expand the need for a lighter weight fuel allowing for longer duration flights has become the primary limiting factor in the advancement of these vehicles. To extend the operational envelope of UAV onboard condensed hydrogen storage for missions exceeding one week is necessary. Currently large spherical liquid hydrogen tanks that are pressurized with external helium tanks or electronic heating elements are utilized for this purpose. However the mass size and power consumption of the fuel storage tank and fuel pressurization system significantly limit the flight envelope of UAV. In an effort to alleviate these issues this paper investigates the technological feasibility of orthohydrogen-parahydrogen catalysis as a method of fuel pressurization. Typical pressurization requirements for takeoff cruise and landing are reviewed. Calculations of the catalyst system mass and response time are presented.

Unmanned deepwater-line repair system passes full-scale trials  

SciTech Connect

The first ever full-scale tests of an unmanned, deepwater-pipeline repair system were successfully conducted last year off the coast of Italy. The Italian gas-transmission company SNAM tested a submersible automatic system (SAS) sealine repair system at a depth of 600 m. The modular SAS allows sealines to be repaired by installation of the Nuovo Pignone mechanical connector. The system's trials simulated complete repair intervention on the 20-in. Trans mediterranean pipeline and provided unprecedented experience to SNAM and to the other involved in this project. The paper discusses the origin of the idea for the SAS, the design of the system, construction and testing, the first sea trials, final deep sea trials, and future developments.

Radiometric and Geometric Analysis of Hyperspectral Imagery Acquired from an Unmanned Aerial Vehicle  

SciTech Connect

In the summer of 2010, an Unmanned Aerial Vehicle (UAV) hyperspectral in-flight calibration and characterization experiment of the Resonon PIKA II imaging spectrometer was conducted at the U.S. Department of Energys Idaho National Laboratory (INL) UAV Research Park. The purpose of the experiment was to validate the radiometric calibration of the spectrometer and determine the georegistration accuracy achievable from the on-board global positioning system (GPS) and inertial navigation sensors (INS) under operational conditions. In order for low-cost hyperspectral systems to compete with larger systems flown on manned aircraft, they must be able to collect data suitable for quantitative scientific analysis. The results of the in-flight calibration experiment indicate an absolute average agreement of 96.3%, 93.7% and 85.7% for calibration tarps of 56%, 24%, and 2.5% reflectivity, respectively. The achieved planimetric accuracy was 4.6 meters (based on RMSE).

Ascent performance feasibility of the national aerospace plane  

SciTech Connect

The national aerospace plane (NASP) is a proposed hypervelocity research vehicle which must take-off horizontally, achieve orbital speed, and then land horizontally. Its configuration is dominated by the powerplant, which includes the combination of turbojet engines for flight at subsonic speeds and low supersonic speeds, ramjet engines for flight at high supersonic speeds, scramjet engines for flight at hypersonic speeds, and rocket engines for flight at near-orbital speeds. Optimal trajectories are studied for a given NASP configuration, the so-called general hypersonic aerodynamics model example, under the assumption that the NASP is controlled via angle of attack and power setting. Three powerplant models are considered: (E1) and (E2) are turbojet, ramjet, scramjet combinations; (E3) is a turbojet, ramjet scramjet, rocket combination, with the rocket mode starting at M = 15. Realistic constraints are imposed on the peak dynamic pressure, peak heating rate, and peak tangential acceleration. Under this scenario, the time history of the controls is optimized simultaneously with the switch times from one engine mode to the next. The optimization criterion is the total mass of fuel required to achieve orbital speed. The optimization study employs the sequential gradient-restoration algorithm for optimal control problems.

Using Unmanned Helicopters to Assess Vegetation Cover in Sagebrush Steppe Ecosystems  

SciTech Connect

Evaluating vegetation cover is an important factor in understanding the sustainability of many ecosystems. Methods that have sufficient accuracy and improved cost efficiency could dramatically alter how biotic resources are monitored on both public and private lands. This will be of interest to land managers because there are rarely enough resource specialists or funds available for comprehensive ground evaluations. In this project, unmanned helicopters were used to collect still-frame imagery to assess vegetation cover during May, June, and July in 2005. The images were used to estimate percent cover for six vegetative cover classes (shrub, dead shrub, grass, forbs, litter, and bare ground). The field plots were located on the INL site west of Idaho Falls, Idaho. Ocular assessments of digital imagery were performed using a software program called SamplePoint, and the results were compared against field measurements collected using a point-frame method to assess accuracy. The helicopter imagery evaluation showed a high degree of agreement with field cover class values for litter, bare ground, and grass, and reasonable agreement for dead shrubs. Shrub cover was often overestimated and forbs were generally underestimated. The helicopter method took 45% less time than the field method to set plots and collect and analyze data. This study demonstrates that UAV technology provides a viable method for monitoring vegetative cover on rangelands in less time and with lower costs. Tradeoffs between cost and accuracy are critical management decisions that are important when managing vegetative conditions across vast sagebrush ecosystems throughout the Intermountain West.

Design of a reconfigurable liquid hydrogen fuel tank for use in the Genii unmanned aerial vehicle  

Science Journals Connector (OSTI)

Long endurance flight on the order of days is a leading flight performance characteristic for Unmanned Aerial Vehicles (UAVs). Liquid hydrogen (LH2) is well suited to providing multi-day flight times with a specific energy 2.8 times that of conventional kerosene based fuels. However no such system of LH2 storage delivery and use is currently available for commercial UAVs. In this paper we develop a light weight LH2 dewar for integration and testing in the proton exchange membrane (PEM) fuel cell powered student designed and constructed Genii UAV. The fuel tank design is general for scaling to suit various UAV platforms. A cylindrical vacuum-jacketed design with removable end caps was chosen to incorporate various fuel level gauging pressurizing and slosh mitigation systems. Heat and mechanical loadings were modeled to compare with experimental results. Mass performance of the fuel tank is characterized by the fraction of liquid hydrogen to full tank mass and the insulation performance was characterized by effective thermal conductivity and boil-off rate.

Comparison of Unmanned Aerial Vehicle Platforms for Assessing Vegetation Cover in Sagebrush Steppe Ecosystems  

SciTech Connect

In this study, the use of unmanned aerial vehicles (UAVs) as a quick and safe method for monitoring biotic resources was evaluated. Vegetation cover and the amount of bare ground are important factors in understanding the sustainability of many ecosystems and assessment of rangeland health. Methods that improve speed and cost efficiency could greatly improve how biotic resources are monitored on western lands. Sagebrush steppe ecosystems provide important habitat for a variety of species (including sage grouse and pygmy rabbit). Improved methods are needed to support monitoring these habitats because there are not enough resource specialists or funds available for comprehensive ground evaluations. In this project, two UAV platforms, fixed wing and helicopter, were used to collect still-frame imagery to assess vegetation cover in sagebrush steppe ecosystems. This paper discusses the process for collecting and analyzing imagery from the UAVs to (1) estimate percent cover for six different vegetation types (shrub, dead shrub, grass, forb, litter, and bare ground) and (2) locate sage grouse using representative decoys. The field plots were located on the Idaho National Engineering (INL) site west of Idaho Falls, Idaho, in areas with varying amounts and types of vegetation cover. A software program called SamplePoint was used along with visual inspection to evaluate percent cover for the six cover types. Results were compared against standard field measurements to assess accuracy. The comparison of fixed-wing and helicopter UAV technology against field estimates shows good agreement for the measurement of bare ground. This study shows that if a high degree of detail and data accuracy is desired, then a helicopter UAV may be a good platform to use. If the data collection objective is to assess broad-scale landscape level changes, then the collection of imagery with a fixed-wing system is probably more appropriate.

Geophex Airborne Unmanned Survey System (GAUSS). Topical report, October 1993--March 1995  

SciTech Connect

The objectives of the project are to construct a geophysical sensor system based on a remotely operated model helicopter (ROH) and to evaluate the efficacy of the system for characterization of hazardous environmental sites. Geophex Airborne Unmanned Survey System (GAUSS) is a geophysical survey system that uses a ROH as the survey vehicle. We have selected the ROH because of its advantages over fixed wing and ground based vehicles. Lower air speed and superior maneuverability of the ROH make it better suited for geophysical surveys than a fixed wing model aircraft. The ROH can fly close to the ground, allowing detection of weak or subtle anomalies. Unlike ground based vehicles, the ROH can traverse difficult terrain while providing a stable sensor platform. ROH does not touch the ground during the course of a survey and is capable of functioning over water and surf zones. The ROH has been successfully used in the motion picture industry and by geology companies for payload bearing applications. The only constraint to use of the airborne system is that the ROH must remain visible to the pilot. Obstructed areas within a site can be characterized by relocating the base station to alternate positions. GAUSS consists of a ROH with radio controller, a data acquisition and processing (DAP) system, and lightweight digital sensor systems. The objective of our Phase I research was to develop a DAP and sensors suitable for ROH operation. We have constructed these subsystems and integrated them to produce an automated, hand-held geophysical surveying system, referred to as the ``pre-prototype``. We have performed test surveys with the pre-prototype to determine the functionality of the and DAP and sensor subsystems and their suitability for airborne application. The objective of the Phase II effort will be to modify the existing subsystems and integrate them into an airborne prototype. Efficacy of the prototype for geophysical survey of hazardous sites will then be determined.

Review of uncertainty-based multidisciplinary design optimization methods for aerospace vehicles  

Science Journals Connector (OSTI)

This paper presents a comprehensive review of Uncertainty-Based Multidisciplinary Design Optimization (UMDO) theory and the state of the art in UMDO methods for aerospace vehicles. UMDO has been widely acknowledged as an advanced methodology to address competing objectives of aerospace vehicle design, such as performance, cost, reliability and robustness. However the major challenges of UMDO, namely the computational complexity and organizational complexity caused by both time-consuming disciplinary analysis models and UMDO algorithms, still greatly hamper its application in aerospace engineering. In recent years there is a surge of research in this field aiming at solving these problems. The purpose of this paper is to review these existing approaches systematically, highlight research challenges and opportunities, and help guide future efforts. Firstly, the UMDO theory preliminaries are introduced to clarify the basic UMDO concepts and mathematical formulations, as well as provide a panoramic view of the general UMDO solving process. Then following the UMDO solving process, research progress of each key step is separately surveyed and discussed, specifically including uncertainty modeling, uncertainty propagation and analysis, optimization under uncertainty, and UMDO procedure. Finally some conclusions are given, and future research trends and prospects are discussed.

Environmental study of the National Aerospace Plane. Final report, 1 December 1991-30 December 1992  

SciTech Connect

The overall objective of the United States (US) National Aero-Space Plane (NASP) Program is to develop hypersonic technologies required for future military and Civilian aerospace plane systems to reduce payload cost to orbit and provide for flexible-responsive space operations. If successful, the NASP Program will be the stimulus for developing a whole new class of airbreathing hypersonic aircraft powered by clean-burning scramjet engines using liquid hydrogen as the primary fuel. As part of this development, the potential to cause environmental impacts from these type of vehicles must be considered and analyzed. This process has been initiated using the NASP Program's proposed X-30 flight research vehicle and flight test program as a basis for analysis. Environmental issues addressed include noise and sonic booms, stratospheric ozone depletion, public health and safety, hazardous materials/waste, air quality, biological and cultural resources, geology and soils, and water use. Although this study is not yet complete, preliminary analysis has determined that the X-30 vehicle and flight test program would have minimal environmental impact.

Advanced model-based FDIR techniques for aerospace systems: Today challenges and opportunities  

Science Journals Connector (OSTI)

This paper discusses some trends and recent advances in model-based Fault Detection, Isolation and Recovery (FDIR) for aerospace systems. The FDIR challenges range from pre-design and design stages for upcoming and new programs, to improvement of the performance of in-service flying systems. For space missions, optimization of flight conditions and safe operation is intrinsically related to GNC (Guidance, Navigation & Control) system of the spacecraft and includes sensors and actuators monitoring. Many future space missions will require autonomous proximity operations including fault diagnosis and the subsequent control and guidance recovery actions. For upcoming and future aircraft, one of the main issues is how early and robust diagnosis of some small and subtle faults could contribute to the overall optimization of aircraft design. This issue would be an important factor for anticipating the more and more stringent requirements which would come in force for future environmentally-friendlier programs. The paper underlines the reasons for a widening gap between the advanced scientific FDIR methods being developed by the academic community and technological solutions demanded by the aerospace industry.

VOC/HAP control systems for the shipbuilding and aerospace industries  

SciTech Connect

Compliant coating systems, i.e., those which meet limits on pounds of volatile organic compound (VOC)/hazardous air pollutant (HAP) per gallon, on a solids applied basis, are routinely used to meet emission regulations in the shipbuilding and aerospace industries. However, there are occasions when solvent based systems must be used. Total capture and high destruction of the solvents in those systems is necessary in order to meet the required emission limit, e.g., a reasonably available control technology (RACT) limit of 3.5lbs of VOC/gallon. Water based marine coatings and certain aerospace finish coats do not provide sufficient longevity or meet other customer specifications in these instances. Furthermore, because of best available control technology (BACT) determinations or facility limits for operation in serious, severe, and extreme nonattainment areas, it is necessary to reduce annual emissions to levels which are below the levels required by the coating standards. The paper discusses those operations for controlling emissions from large-scale solvent based painting and coating systems in those instances when a high degree of overall control is required. Permanent total enclosures (stationary and portable), concentrators, regenerative thermal oxidizers, and other air pollution control systems are evaluated, both for technical applicability and economic feasibility. Several case studies are presented which illustrate techniques for capturing painting emissions, options for air handling in the workplace, and methods for destroying exhaust stream VOC concentrations of less than 40 ppm.

Predictions from the macrohomogeneous model of an aerospace Ni-Cd battery  

SciTech Connect

The mathematical porous-electrode model developed at Texas A and M University has been combined with a planar model for the surface active layer to formulate a pseudo two-dimensional model for a sealed nickel-cadmium cell. The porous electrode model is based on a macrohomogeneous description of the electrodes and takes into account various processes such as mass transport in the liquid phase and porosity and conductivity changes in the solid phase. The planar electrode model describes the processes occurring across the surface layer of active material, i.e., solid-state diffusion of protons and conductivity changes in the nickel oxide, and the charge-transfer across the film-electrolyte interface. Also, various routines have been added to the pseudo two-dimensional model thus integrated, to allow predictions for any nickel-cadmium battery under any desired charge-discharge schedule. From a comparison with the experimental data of an aerospace cell, the model parameters describing charge-discharge behavior of a Ni-Cd cell have been optimized to obtain a closer prediction with the experimental data. Upon optimizing the model parameters, the performance of the aerospace nickel-cadmium cell has been simulated under various experimental conditions, i.e., at different rates and temperatures. Also, generic Ragone plots for the cell and typical Tafel plots for cadmium and nickel electrodes at different states of charge have been constructed form the simulations. Finally, this model has been made available for any interested user through COSMIC NASA`s Computer Management and Information Center, along with documentation in six volumes describing the code, principles, and operating instructions.

Unmanned airborne vehicle (UAV): Flight testing and evaluation of two-channel E-field very low frequency (VLF) instrument  

SciTech Connect

Using VLF frequencies, transmitted by the Navy`s network, for airborne remote sensing of the earth`s electrical, magnetic characteristics was first considered by the United States Geological Survey (USGS) around the mid 1970s. The first VLF system was designed and developed by the USGS for installation and operation on a single engine, fixed wing aircraft used by the Branch of Geophysics for geophysical surveying. The system consisted of five channels. Two E-field channels with sensors consisting of a fixed vertical loaded dipole antenna with pre-amp mounted on top of the fuselage and a gyro stabilized horizontal loaded dipole antenna with pre-amp mounted on a tail boom. The three channel magnetic sensor consisted of three orthogonal coils mounted on the same gyro stabilized platform as the horizontal E-field antenna. The main features of the VLF receiver were: narrow band-width frequency selection using crystal filters, phase shifters for zeroing out system phase variances, phase-lock loops for generating real and quadrature gates, and synchronous detectors for generating real and quadrature outputs. In the mid 1990s the Branch of Geophysics designed and developed a two-channel E-field ground portable VLF system. The system was built using state-of-the-art circuit components and new concepts in circuit architecture. Small size, light weight, low power, durability, and reliability were key considerations in the design of the instrument. The primary purpose of the instrument was for collecting VLF data during ground surveys over small grid areas. Later the system was modified for installation on a Unmanned Airborne Vehicle (UAV). A series of three field trips were made to Easton, Maryland for testing and evaluating the system performance.

Validation of mixed mode propagation criteria and development of experimental protocol to determine material fracture mechanics parameters. A robust numerical F.E. computation scheme (modified virtual crack extension) to assess energy released rate and mode partition along the delamination tip. Illustrations of the method will be presented through two typical configurations: Local delamination near the surface in a monolithic composite. Debonding between skin and honeycomb core of a sandwich structures. The second part will detail extension of the methodology proposed previously to assess failure mechanisms during static compression after impact of a monolithic composite plate. The damage morphology of an impacted composite plate is characterised by multi-delaminations with a typical helix geometry. The ruin mechanism is regarded as an elastic non-linear behaviour in the damaged area due to a progressive local buckling of delaminated plies until a coupled bending-compression failure. Damage evolution is predicted by introduction of delaminations in a 3D F.E. model with non-penetration contact conditions and elastic properties degradation of the damaged plies. Techniques to manage a mesh with multi-delaminations will be detailed.

Magnetic Processing A Pervasive Energy Efficient Technology for Next Generation Materials for Aerospace and Specialty Steel Markets  

SciTech Connect

Thermomagnetic Magnetic Processing is an exceptionally fertile, pervasive and cross-cutting technology that is just now being recognized by several major industry leaders for its significant potential to increase energy efficiency and materials performance for a myriad of energy intensive industries in a variety of areas and applications. ORNL has pioneered the use and development of large magnetic fields in thermomagnetically processing (T-MP) materials for altering materials phase equilibria and transformation kinetics. ORNL has discovered that using magnetic fields, we can produce unique materials responses. T-MP can produce unique phase stabilities & microstructures with improved materials performance for structural and functional applications not achieved with traditional processing techniques. These results suggest that there are unprecedented opportunities to produce significantly enhanced materials properties via atomistic level (nano-) microstructural control and manipulation. ORNL (in addition to others) have shown that grain boundary chemistry and precipitation kinetics are also affected by large magnetic fields. This CRADA has taken advantage of ORNLs unique, custom-designed thermo-magnetic, 9 Tesla superconducting magnet facility that enables rapid heating and cooling of metallic components within the magnet bore; as well as ORNLs expertise in high magnetic field (HMF) research. Carpenter Technologies, Corp., is a a US-based industrial company, that provides enhanced performance alloys for the Aerospace and Specialty Steel products. In this CRADA, Carpenter Technologies, Corp., is focusing on applying ORNLs Thermomagnetic Magnetic Processing (TMP) technology to improve their current and future proprietary materials product performance and open up new markets for their Aerospace and Specialty Steel products. Unprecedented mechanical property performance improvements have been demonstrated for a high strength bainitic alloy industrial/commercial alloy that is envisioned to provide the potential for new markets for this alloy. These thermomechanical processing results provide these alloys with a major breakthrough demonstrating that simultaneous improvements in yield strength and ductility are achieved: 12 %, 10%, 13%, and 22% increases in yield strength, elongation, reduction-in-area, and impact energy respectively. In addition, TMP appears to overcome detrimental chemical homogeneity impacts on uniform microstructure evolution.

Linking, leveraging and learning: sectoral systems of innovation and technological catch-up in China's commercial aerospace industry  

Science Journals Connector (OSTI)

Developing countries often have ambitions to become major players in the commercial aerospace industry, but it remains effectively a duopoly dominated by Boeing of the USA and Europe's Airbus. China is no exception and the projects designed to bring this about have taken a number of forms. Adopting the sectoral system of innovation (SSI) as an analytical framework, this paper explores recent changes in the industry. Using China's ARJ21 regional jet programme as a case study, it examines how these changes provide opportunities for latecomer nations to catch-up technologically. It is argued that the new institutional context and the presence of new actors within the SSI, represent an opportunity for latecomer nations like China to acquire the capability to design, develop and manufacture commercial jet airliners, through linking with Western suppliers. However the analysis reveals that as a latecomer nation, China may prove to be a special case, with the opportunities for catch-up by other latecomers much more limited.

Hypersonic aerospace vehicle leading-edge cooling using heat-pipe, transpiration and film-cooling techniques  

SciTech Connect

The feasibility of cooling hypersonic-vehicle leading-edge structures exposed to severe aerodynamic surface heat fluxes was studied, using a combination of liquid-metal heat pipes and surface-mass-transfer cooling techniques. A generalized, transient, finite-difference-based hypersonic leading-edge cooling model was developed that incorporated these effects and was demonstrated on an assumed aerospace plane-type wing leading edge section and a SCRAMJET engine inlet leading-edge section. The hypersonic leading-edge cooling model was developed using an existing, experimentally verified heat-pipe model. Then the existing heat-pipe model was modified by adding both transpiration and film-cooling options as new surface boundary conditions. The models used to predict the leading-edge surface heat-transfer reduction effects of the transpiration and film cooling were modifications of more-generalized, empirically based models obtained from the literature. It is concluded that cooling leading-edge structures exposed to severe hypersonic-flight environments using a combination of liquid-metal heat pipe, surface transpiration, and film cooling methods appears feasible.

Development of CSS-42L{trademark}, a high performance carburizing stainless steel for high temperature aerospace applications  

SciTech Connect

Today`s aerospace engineering challenges demand materials which can operate under conditions of temperature extremes, high loads and harsh, corrosive environments. This paper presents a technical overview of the on-going development of CSS-42L (US Patent No. 5,424,028). This alloy is a case-carburizable, stainless steel alloy suitable for use in applications up to 427 C, particularly suited to high performance rolling element bearings, gears, shafts and fasteners. The nominal chemistry of CSS-42L includes: (by weight) 0.12% carbon, 14.0% chromium, 0.60% vanadium, 2.0% nickel, 4.75% molybdenum and 12.5% cobalt. Careful balancing of these components combined with VIM-VAR melting produces an alloy that can be carburized and heat treated to achieve a high surface hardness (>58 HRC at 1mm (0.040 in) depth) with excellent corrosion resistance. The hot hardness of the carburized case is equal to or better than all competitive grades, exceeding 60 HRC at 427 C. The fracture toughness and impact resistance of the heat treated core material have likewise been evaluated in detail and found to be better than M50-NiL steel. The corrosion resistance has been shown to be equivalent to that of 440C steel in tests performed to date.

The hydrogen value chain: applying the automotive role model of the hydrogen economy in the aerospace sector to increase performance and reduce costs  

Science Journals Connector (OSTI)

Hydrogen will assume a key role in Europe's effort to adopt its energy dependent society to satisfy its needs without releasing vast amounts of greenhouse gases. The paradigm shift is so paramount that one speaks of the Hydrogen Economy, as the energy in this new and ecological type of economy is to be distributed by hydrogen. However, H2 is not a primary energy source but rather an energy carrier, a means of storing, transporting and distributing energy, which has to be generated by other means. Various H2 storage methods are possible; however industries' favourite is the storage of gaseous hydrogen in high pressure tanks. The biggest promoter of this storage methodology is the automotive industry, which is currently preparing for the generation change from the fossil fuel internal combustion engines to hydrogen based fuel cells. The current roadmaps foresee a market roll-out by 2015, when the hydrogen supply infrastructure is expected to have reached a critical mass. The hydrogen economy is about to take off as being demonstrated by various national mobility strategies, which foresee several millions of electric cars driving on the road in 2020. Fuel cell cars are only one type of electric car, battery electric as well as hybrid cars all featuring electric drive trains are the others. Which type of technology is chosen for a specific application depends primarily on the involved energy storage and power requirements. These considerations are very similar to the ones in the aerospace sector, which had introduced the fuel cell already in the 1960s. The automotive sector followed only recently, but has succeeded in moving forward the technology to a level, where the aerospace sector is starting considering to spin-in terrestrial hydrogen technologies into its technology portfolio. Target areas are again high power/high energy applications like aviation, manned spaceflight and exploration missions, as well as future generation high power telecommunication satellites. Similar trends can be expected in the future for RADAR Earth Observation satellites and space infrastructure concepts of great scale. This paper examines current activities along the hydrogen value chain, both in the terrestrial and the aerospace sector. A general assessment of the synergy potential is complemented by a thorough analysis of specific applications serving as role models like a lunar manned base or pressurised rover, an aircraft APU or a high power telecommunications satellite. Potential performance improvements and cost savings serve as key performance indicators in these comparisons and trade-offs.

The aircraft was softly suspended and then excited using random input from a long-stroke shaker. Modal data was taken from 92 measurement locations on the aircraft using newly designed, lightweight, tri-axial accelerometers. A conventional PC-based data acquisition system provided data handling. Modal parameters were calculated, and animated mode shapes were produced using SMS STARStruct{trademark} Modal Analysis System software. The modal parameters will be used for validation of finite element models, optimum placement of onboard accelerometers during flight testing, and vibration isolation design of sensor platforms.

That is new micro-thermonuclear reactor with very small fuel pellet that uses plasma confinement generated by multi-reflection of laser beam or its own magnetic field. The Lawson criterion increases by hundreds of times. The author also suggests a new method of heating the power-making fuel pellet by outer electric current as well as new direct method of transformation of ion kinetic energy into harvestable electricity. These offered innovations dramatically decrease the size, weight and cost of thermonuclear reactor, installation, propulsion system and electric generator. Non-industrial countries can produce these researches and constructions. Currently, the author is researching the efficiency of these innovations for two types of the micro-thermonuclear reactors: multi-reflection reactor (ICF) and self-magnetic reactor (MCF).

Atmospheric Radiation Measurement Program facilities newsletter, January 2000  

SciTech Connect

The subject of this newsletter is the ARM unmanned aerospace vehicle program. The ARM Program's focus is on climate research, specifically research related to solar radiation and its interaction with clouds. The SGP CART site contains highly sophisticated surface instrumentation, but even these instruments cannot gather some crucial climate data from high in the atmosphere. The Department of Energy and the Department of Defense joined together to use a high-tech, high-altitude, long-endurance class of unmanned aircraft known as the unmanned aerospace vehicle (UAV). A UAV is a small, lightweight airplane that is controlled remotely from the ground. A pilot sits in a ground-based cockpit and flies the aircraft as if he were actually on board. The UAV can also fly completely on its own through the use of preprogrammed computer flight routines. The ARM UAV is fitted with payload instruments developed to make highly accurate measurements of atmospheric flux, radiance, and clouds. Using a UAV is beneficial to climate research in many ways. The UAV puts the instrumentation within the environment being studied and gives scientists direct measurements, in contrast to indirect measurements from satellites orbiting high above Earth. The data collected by UAVs can be used to verify and calibrate measurements and calculated values from satellites, therefore making satellite data more useful and valuable to researchers.

Thermal conductivity of rigid foam insulations for aerospace vehicles  

Science Journals Connector (OSTI)

The present work describes measurements of the effective thermal conductivity of NCFI 24-124 foam, a spray-on foam insulation used formerly on the Space Shuttle external fuel tank. A novel apparatus to measure the effective thermal conductivity of rigid foam at temperatures ranging from 20K to 300K was developed and used to study three samples of NCFI 24-124 foam insulation. In preparation for measurement, the foam samples were either treated with a uniquely designed moisture absorption apparatus or different residual gases to study their impact on the effective thermal conductivity of the foam. The resulting data are compared to other measurements and mathematical models reported in the literature.

Design of Small Impact-Resistant RTGs for Global Network of Unmanned Mars Landers  

SciTech Connect

Presented at the 42nd Congress of the IAF, October 5-11, 1991 in Montreal, Canada. This paper presents the results of Fairchild's work in support of DOE to perform RTG design studies for this mission. The key problem in designing these RTGs is how to enable the generators to tolerate substantially higher g-loads than those encountered on previous RTG missions. The Fairchild studies resulted in designs of compact RTGs based on flight-proven and safety-qualified heat source components, with a number of novel features designed to provide the desired high impact tolerance. The present paper describes those designs and their rationale, and a preliminary, quasi-static impact analysis that yielded very encouraging results. They indicate that these RTGs have sufficient impact resistance to enable survival of landers without retrorockets. This would result in significant cost savings. There are four copies in the file. Two copies of a presentation with the same title by Al Schock dated June 26/27, 1991 is attached. There are two copies of a Fairchild document, undated included. There is also two copies dated 6/26/1991 with the report number FSC-ESD-217-91-495 and one copy of a ducument, dated 7/11/191 with the report number FSC-ESD-217-91-495A.

A Time-Slotted On-Demand Routing Protocol for Mobile Ad Hoc Unmanned Vehicle Systems  

SciTech Connect

The popularity of UAVs has increased dramatically because of their successful deployment in military operations, their ability to preserve human life, and the continual improvements in wireless communication that serves to increase their capabilities. We believe the usefulness of UAVs would be dramatically increased if formation flight were added to the list of capabilities. Currently, sustained formation flight with a cluster of UAVs has only been achieved with two nodes by the Multi-UAV Testbed at the Massachusetts Institute of Technology. (Park, 2004) Formation flight is a complex operation requiring the ability to adjust the flight patterns on the fly and correct for wind gusts, terrain, and differences in node equipment. All of which increases the amount of inner node communication. Since one of the problems with MANET communication is network congestion, we believe a first step towards formation flight can be made through improved inner node communication. We have investigated current communication routing protocols and developed an altered hybrid routing protocol in order to provide communication with less network congestion.

Multi Spectral Pushbroom Imaging Radiometer (MPIR) for remote sensing cloud studies  

SciTech Connect

A Multi Spectral Pushbroom Imaging Radiometer (MPIR) has been developed as are relatively inexpensive ({approximately}$IM/copy), well-calibrated,imaging radiometer for aircraft studies of cloud properties. The instrument is designed to fly on an Unmanned Aerospace Vehicle (UAV) platform at altitudes from the surface up to 20 km. MPIR is being developed to support the Unmanned Aerospace Vehicle portion of the Department of Energy`s Atmospheric Radiation Measurements program (ARM/UAV). Radiation-cloud interactions are the dominant uncertainty in the current General Circulation Models used for atmospheric climate studies. Reduction of this uncertainty is a top scientific priority of the US Global Change Research Program and the ARM program. While the DOE`s ARM program measures a num-ber of parameters from the ground-based Clouds and Radiation Testbed sites, it was recognized from the outset that other key parameters are best measured by sustained airborne data taking. These measurements are critical in our understanding of global change issues as well as for improved atmospheric and near space weather forecasting applications.

ARM-UAV: The Next Phase ARM-UAV: The Next Phase J. Vitko, Jr. and T. P. Tooman Sandia National Laboratories Livermore, California R. G. Ellingson University of Maryland College Park, Maryland Introduction The Atmospheric Radiation Measurement-Unmanned Aerospace Vehicle (ARM-UAV) Program was initiated in 1993 to develop a capability to provide radiation and cloud measurements at the top of the troposphere, thereby capping the top of the grid cell above ARM sites. To date, ARM-UAV has developed the necessary payloads and measurement techniques for radiative flux measurements at mid-latitudes. The upcoming Kauai mission completes the original vision by extending these capabilities to cloud measurements and tropical altitudes. Beyond Kauai, with development largely though not completely done, we will begin transitioning to an operational phase to better support ARM's

The CMR is a 95-GHz solid-state radar intended for airborne cloud measurements. Funding for the project was provided by the Atmospheric Radiation Measurement-Unmanned Aerospace Vehicle (ARM-UAV) program with the eventual goal of developing a radar capable of operating on the Altus UAV. Simultaneous measurements made by CMR and the Cloud Profiling Radar System (CPRS) have been made to evaluate CMR's performance. CPRS is a larger

Strategic Environmental Research and Development Program: Atmospheric Remote Sensing and Assessment Program -- Final Report. Part 1: The lower atmosphere  

SciTech Connect

This report documents work done between FY91 and FY95 for the lower atmospheric portion of the joint Department of Defense (DoD) and Department of Energy (DOE) Atmospheric Remote Sensing and Assessment Program (ARSAP) within the Strategic Environmental Research and Development Program (SERDP). The work focused on (1) developing new measurement capabilities and (2) measuring atmospheric heating in a well-defined layer and then relating it to cloud properties an water vapor content. Seven new instruments were develop3ed for use with Unmanned Aerospace Vehicles (UAVs) as the host platform for flux, radiance, cloud, and water vapor measurements. Four major field campaigns were undertaken to use these new as well as existing instruments to make critically needed atmospheric measurements. Scientific results include the profiling of clear sky fluxes from near surface to 14 km and the strong indication of cloudy atmosphere absorption of solar radiation considerably greater than predicted by extant models.

The methane-acetylene cycle Aerospace Plane - A promising candidate for earth to orbit transportation  

SciTech Connect

The methane-acetylene cycle Aerosapce Plane (MACASP) concept is proposed and its theoretical feasibility is shown. In this concept, methane fuel stored on-board the aircraft is run out within the wing leading edge in pipes at temperatures up to 1400 K. In the presence of catalyst, the heat provided by wing drag is used to drive the highly endothermic chemical reaction 2CH4 yields 3H2 + C2H2. The products of this reaction, hydrogen and acetylene, are then fed into a combustion chamber and burned in air. On the NASP, terminal acceleration to orbit beyond the critical Mach number of the scramjet can be enabled by rocket operation using a small on-board supply of LOx. The advantages of this concept are that the two highly energetic but difficult-to-store fuels can be used without on-board storage. It is shown that the MACASP concept offers significant promise for economical earth-to-orbit transportation. 5 refs.

Nonlinear control problems and their approximations for thin dynamic shallow shells in aerospace  

SciTech Connect

A nonlinear system describing the vibrations of a thin shallow shell win be considered. These equations arise in the modeling of large flexible structures such as solar collectors and reflective mirrors. This paper will address questions related to well-posedness: existence, uniqueness and regularity of solutions. However, the main goals of the paper are (i) to examine the asymptotic behavior of solutions subject to a suitable dissipative mechanism applied to the model, and (ii) to provide a framework for numerical approximations of stabilizing solutions. Of particular interest are problems associated with dissipation acting on the boundary of the shell. The paper will detail conditions under which uniform decay of the energy function can be achieved. This is related to avoiding everted states, a phenomenon involving the ratio of thickness to curvature for which there is no analogue in plate theory.

A reactionless, bearingless linear shutter mechanism for the multispectral pushbroom imaging radiometer  

SciTech Connect

The Atmospheric Radiation Measurement Program is a multi-laboratory, interagency program as part of DOE`s principal entry into the US Global Change Research Program. Two issues addressed are the radiation budget and its spectral dependence, and radiative and other properties of clouds. Measures of solar flux divergence and energy exchanges between clouds, the earth, its oceans, and the atmosphere through various altitudes are sought. Additionally, the program seeks to provide measurements to calibrate satellite radiance products and validate their associated flux retrieval algorithms. Unmanned Aerospace Vehicles fly long, extended missions. MPIR is one of the primary instruments on the ARM-UAV campaigns. A shutter mechanism has been developed and flown as part of an airborne imaging radiometer having application to spacecraft or other applications requiring low vibration, high reliability, and long life. The device could be employed in other cases where a reciprocating platform is needed. Typical shutters and choppers utilize a spinning disc, or in very small instruments, a vibrating vane to continually interrupt incident light or radiation that enters the system. A spinning disk requires some sort of bearings that usually have limited life, and at a minimum introduce issues of reliability. Friction, lubrication and contamination always remain critical areas of concern, as well as the need for power to operate. Dual vibrating vanes may be dynamically well balanced as a set and are frictionless. However, these are limited by size in a practical sense. In addition, multiples of these devices are difficult to synchronize.

Design of a differential radiometer for atmospheric radiative flux measurements  

SciTech Connect

The Hemispherical Optimized NEt Radiometer (HONER) is an instrument under development at the Los Alamos National Laboratory for deployment on an unmanned aerospace vehicle as part of the Atmospheric Radiation Measurements (ARM/UAV) program. HONER is a differential radiometer which will measure the difference between the total upwelling and downwelling fluxes and is intended to provide a means of measuring the atmospheric radiative flux divergence. Unlike existing instruments which measure the upwelling and downwelling fluxes separately, HONER will achieve an optical difference by chopping the two fluxes alternately onto a common pyroelectric detector. HONER will provide data resolved into two spectral bands; one covering the solar dominated region from less than 0.4 micrometer to approximately 4.5 micrometers and the other covering the region from approximately 4.5 micrometers to greater than 50 micrometers, dominated by thermal radiation. The means of separating the spectral regions guarantees seamless summation to calculate the total flux. The fields-of-view are near-hemispherical, upward and downward. The instrument can be converted, in flight, from the differential mode to absolute mode, measuring the upwelling and downwelling fluxes separately and simultaneously. The instrument also features continuous calibration from on-board sources. We will describe the design and operation of the sensor head and the on-board reference sources as well as the means of deployment.

Design of Optimal Regulators  

E-Print Network (OSTI)

Current research suggests the use of a liner quadratic performance index for optimal control of regulators in various applications. Some examples include correcting the trajectory of rocket and air vehicles, vibration suppression of flexible structures, and airplane stability. In all these cases, the focus is in suppressing/decreasing system deviations rapidly. However, if one compares the Linear Quadratic Regulator (LQR) solution with optimal solutions (minimum time), it is seen that the LQR solution is less than optimal in some cases indeed (3-6) times that obtained using a minimum time solution. Moreover, the LQR solution is sometimes unacceptable in practice due to the fact that values of control extend beyond admissible limits and thus the designer must choose coefficients in the linear quadratic form, which are unknown. The authors suggest methods which allow finding a quasi-optimal LQR solution with bounded control which is closed to the minimum time solution. They also remand the process of the minimum time decision. Keywords: Optimal regulator, minimum time controller, Linear Quadratic Regulator (LQR). -- This paper is declared a work of the U.S. Government and not subject to copyright protection in the USA.

Fall 2002 Intensive Operation Periods: Single Column Model and Unmanned Aerospace Vehicle--In an Intensive Operation Period (IOP) on November 3-23, 2002, researchers at the SGP CART site are collecting a detailed data set for use in improving the Single Column Model (SCM), a scaled-down climate model. The SCM represents one vertical column of air above Earth's surface and requires less computation time than a full-scale global climate model. Researchers first use the SCM to efficiently improve submodels of clouds, solar radiation transfer, and atmosphere-surface interactions, then implement the results in large-scale global models. With measured values for a starting point, the SCM predicts atmospheric variables during prescribed time periods. A computer calculates values for such quantities as the amount of solar radiation reaching the surface and predicts how clouds will evolve and interact with incoming light from the sun. Researchers compare the SCM's predictions with actual measurements made during the IOP, then adjust the submodels to make predictions more reliable. A second IOP conducted concurrently with the SCM IOP involves high-altitude, long-duration aircraft flights. The original plan was to use an unmanned aerospace vehicle (UAV), but the National Aeronautics and Space Administration (NASA) aircraft Proteus will be substituted because all UAVs have been deployed elsewhere. The UAV is a small, instrument-equipped, remote-control plane that is operated from the ground by a computer. The Proteus is a manned aircraft, originally designed to carry telecommunications relay equipment, that can be reconfigured for uses such as reconnaissance and surveillance, commercial imaging, launching of small space satellites, and atmospheric research. The plane is designed for two on-board pilots in a pressurized cabin, flying to altitudes up to 65,000 feet for as long as 18 hours. The Proteus has a variable wingspan of 77-92 feet and is 56 feet long. The plane can carry up to 7,260 pounds of equipment, making it a versatile research tool. The Proteus is making measurements at the very top of the cirrus cloud layer to characterize structures of these clouds. These new measurements will provide more accurate, more abundant data for use in improving the representation of clouds in the SCM. 2002-2003 Winter Weather Forecast--Top climate forecasters at the National Oceanic and Atmospheric Administration's (NOAA's) Climate Prediction Center say that an El Nino condition in the tropical Pacific Ocean will influence our winter weather this year. Although this El Nino is not as strong as the event of the 1997-1998 winter season, the United States will nevertheless experience some atypical weather. Strong impacts could be felt in several areas. Nationally, forecasters are predicting warmer-than-average temperatures over the northern tier of states and wetter-than-average conditions in the southern tier of states during the 2002-2003 winter season. Kansas residents should expect warmer and wetter conditions, while Oklahoma will be wetter than average.
