Update on Stirling Radioisotope Power Systems Development at NASA Glenn Research Center

NASA Glenn Research Center (GRC) continues to lead the Agency in research and development of Stirling Radioisotope Power Systems for space and terrestrial applications. Today this work continues under the High Efficiency Power and Generation Technology (HEP-GT) task under the Radioisotope Power Systems (RPS) Program in the Science Mission Directorate. Most of this work is conducted in the Stirling Research Laboratory (SRL) at GRC. Ongoing testing is aimed at increasing the Technology Readiness Level (TRL) of state-of-the-art Free-Piston Stirling Engines (FPSEs) and various subsystems in environmental demonstrations further statistically and experimentally validating their robustness and reliability. The following is an update on the ongoing work within the SRL to achieve these goals.
