Fiscal Year 1993 annual report for the Bubble Membrane Radiator Project
This report summarizes the activities conducted on the Bubble Membrane Radiator (BMR) Project during Fiscal Year (FY) 1993 at the Pacific Northwest Laboratory (PNL) in Richland, Washington. Funding for this work has been provided by the National Aeronautics and Space Administration (NASA), Lyndon B. Johnson Space Center (JSC), Crew and Thermal Sciences Division. The BMR Project was initiated at PNL in March 1988 to continue development of promising thermal management concepts for space applications. In FY 1992 work was refocused from the BMR to fabrication and testing of ultralight fabric reflux tubes (UFRT) because of progress in this area and the desire to incorporate this concept in thermal management for a lunar colony. Development, optimization, and testing of UFRTs continued in FY 1993 under five tasks. Task B, Radiative Properties, and Task D, Development of Tough Metal UFRT Technology, were initiated in FY 1992 and completed this year. Three additional tasks were initiated: Task 1, Fabricate Tubes; Task 2, Heat Transfer Optimization; and Task 3, Analyses Follow-On. A summary of the activities under these tasks and conclusions are provided below.
