Conceptual design of a 500 watt solar AMTEC space power system Conference Paper uri icon


  • This paper describes a conceptual design of an innovative, low-cost, reliable, low-mass, long-life, 500-watt Solar Alkali Metal Thermal to Electric Converter (S-AMTEC) power system, and the predicted system performance. The concept uses high-voltage AMTEC cells, each containing 7 to 9 small electrolyte tubes, integrated with an individual TES unit. The TES used is the LiF-22% CaF2unit currently being developed at NASA Lewis Research Center. Batteries could be placed in place of TES. The system was designed to provide 500 watts of electrical power at 28 volts to a payload in Low Earth Orbit for a minimum lifetime of 5 years.
