An overview of the National Aeronautics and Space Administration (NASA) Lewis Research Center free-piston Stirling engine activities is presented. These activities include work efforts to improve and advance the design of free-piston Stirling engines for use in specific space power applications. These work efforts are a part of the SP-100 program being conducted to support the Department of Defense (DOD), Department of Energy (DOE) and NASA. Such work efforts include: the testing and improvement of 25 kWe Stirling Space Power Demonstrator Engine (SPDE), the preliminary design of 25 kWe single-cylinder Experimental Stirling Space Engine (ESSE), and a study to determine the feasibility of scaling a single-cylinder free-piston Stirling engine/linear alternator to 150 kWe. Other NASA Lewis free-piston Stirling engine activities will be described which are directed toward the advancement of general free-piston Stirling engine technology and application of that technology in specific terrestrial applications. One such work effort, supported by DOE/Oak Ridge National Laboratory (ORNL), is the technology development of a free-piston Stirling engine which produces hydraulic power. Finally, a terrestrial solar application that involves a conceptual design of a 25 kWe solar Advanced Stirling Conversion System (ASCS) capable of delivering power to an electric utility grid will be discussed. This solar work is supported by DOE/Sandia National Laboratory (SNLA).
