- An overview is presented of the National Aeronautics and Space Administration (NASA) Lewis Research Center (LeRC) free-piston Stirling engine activities directed toward space-power application. One of the major elements of the program is the development of advanced power conversion of which the Stirling cycle is a viable candidate. Under this program the status of the 25 kWe opposed-piston Space Power Demonstrator Engine (SPDE) is presented. Technology work is also conducted on heat-exchanger concepts, both design and fabrication, to minimize the number of joints as well as to enhance the heat transfer in the heater. Design parameters and conceptual design features are also presented for a 25 kWe, single-cylinder free-piston Stirling space-power converter. Projections are made for future space-power requirements over the next few decades along with a recommendation to consider the use of dynamic power-conversion systems - either solar or nuclear. A description of a study to investigate the feasibility of scaling a single-cylinder free-piston Stirling space-power module to the 150 kWe power range is presented.
