The U.S. Government is evaluating requirements for future space applications. As power requirements increase, solar or nuclear dynamic systems become increasingly attractive. Free-Piston Stirling Engines (FPSEs) have the potential to provide high reliability, long life, and efficient operation at reasonable hot-side temperatures. Therefore, they are excellent candidates for the dynamic power conversion module of a space-based, power-generating system. FPSEs are at an early stage of technological development; they have not yet demonstrated all the attributes necessary for a space-power system. Mechanical Technology Incorporated (MTI) is executing a program to demonstrate a Space Power Demonstrator Engine (SPDE) which will address major feasibility issues. MTI is also preparing FPSE parameter data to provide major space power system contractors sufficient information to select final Stirling system operating conditions. This paper provides an overview of the SPDE program objectives, the SPDE design and anticipated performance levels, and Stirling engine parametric data.
