The conceptual design of a free-piston Stirling Space Engine (SSE) intended for space power applications has been generated under a National Aeronautics and Space Administration (NASA) contract. This contractual effort was funded by the SP-100 project and managed by the Lewis Research Center (LeRC). The engine was designed to produce 25 kW of electric power with heat being supplied to the engine by a nuclear reactor. A novel heat exchanger module was designed with the intent of reducing the number of critical joints in the heat exchanger assembly while also incorporating a heat pipe as the link between the engine and the heat source. Before incorporating this novel design into a 25 kW Stirling power conversion unit it is desirable to conduct some inexpensive verification tests. Two such approaches are planned. The less costly approach entails attaching 3 heat pipe modules to components remaining from the previously tested RE-1000/dashpot loaded 1 kW engine. A more comprehensive verification test modifies the 12.5 kW Space Power Research Engine (SPRE) for 40 heat pipe modules similar to those proposed for the SSE.
