Progress Towards the Development of a Long-Lived Venus Lander Duplex System
AUTHOR | Nasa, National Aeronautics and Space Adm |
PUBLISHER | Independently Published (01/18/2019) |
PRODUCT TYPE | Paperback (Paperback) |
Description
NASA has begun the development of a combined Stirling cycle power and cooling system (duplex) to enable the long-lived surface exploration of Venus and other harsh environments in the solar system. The duplex system will operate from the heat provided by decaying radioisotope plutonium-238 or its substitute. Since the surface of Venus has a thick, hot, and corrosive atmosphere, it is a challenging proposition to maintain sensitive lander electronics under survivable conditions. This development effort requires the integration of: a radioisotope or fission heat source; heat pipes; high-temperature, corrosion-resistant material; multistage cooling; a novel free-displacer Stirling convertor for the lander; and a minimal vibration thermoacoustic Stirling convertor for the seismometer. The first year effort includes conceptual system design and control studies, materials development, and prototype hardware testing. A summary of these findings and test results is presented in this report. Dyson, Rodger, W. and Bruder, Geoffrey A. Glenn Research Center NASA/TM-2011-217018, AIAA Paper 2010-6917, E-17389-1
