Title: Reactor Power for Large Displacement Autonomous Underwater Vehicles

Abstract

This is a PentaChart on reactor power for large displacement autonomous underwater vehicles. Currently AUVs use batteries or combinations of batteries and fuel cells for power. Battery/fuel cell technology is limited by duration. Batteries and cell fuels are a good match for some missions, but other missions could benefit greatly by a longer duration. The goal is the following: to design nuclear systems to power an AUV and meet design constraints including non-proliferation issues, power level, size constraints, and power conversion limitations. The action plan is to continue development of a range of systems for terrestrial systems and focus on a system for Titan Moon as alternative to Pu-238 for NASA.

  • This report describes research performed during the first two years on the project Vision-Based Navigation for Autonomous Vehicles being conducted under DARPA support. The report contains discussion of four main topics: (1) Development of a vision system for autonomous navigation of roads and road network. (2) Support of Martin Marietta Aerospace, Denver, the integrating contractor on DARPA's ALV program. (3) Experimentation with the vision system developed at Maryland on the Martin Marietta ALV, and (4) Development and implementation of parallel algorithms for visual navigation on the parallel computers developed under the DARPA Strategic Computing Program--specifically, the WARP systolic array processor,more » the Butterfly, and the Connection Machine.« less
  • This report provides a technical overview of research supported under an AASERT (Augmentation Awards for Science and Engineering Research Training) grant administered by the U.S. Air Force Office of Scientific Research. The grant was tied to a parent grant AFOSR-90-0226 and its follow-on F49620-96-1-0059, both of which bear the title `The Nonlinear Control Theory of Complex Mechanical Systems`. The period of performance of the subject ASSERT grant was Sep 94 through Aug 97. Funds from this grant were used to support the PhD thesis research of Geoffrey Howell as stipulated in the original proposal submitted in the Fall of 1993.more » Mr. Howell is expected to finish his dissertation and all degree requirements this year. The research described in this report (and which will be reported in greater detail in Geoff Howell`s dissertation) is concerned with two interrelated themes in the control of super-actuated (or underactuated) mechanical systems: (1) how to control the degrees of freedom which are directly actuated without eliciting undesired behavior in the unactuated degrees of freedom, and (2) how to prescribe motions of the directly actuated degrees of freedom to achieve motion objectives for the degrees of freedom which are not directly controlled.« less
