“…The RG-55 hardware alone has accrued well over 16,500 operating hours at STC. The RG-55 has demonstrated reliability, efficiency, and robustness through testing at both STC and NASA facilities (Qiu, 2002a;Thieme, 2002). Launch-load vibration testing was additionally performed at NASA Glenn Research Center (Hughes, 2001).…”

Long-life radioisotope-fueled generators based on free-piston Stirling convertors are an energy-conversion solution for future space applications. The high efficiency of Stirling machines makes them more attractive than the thermoelectric generators currently used in space. Stirling Technology Company (STC) has been performance-testing its Stirling generators to provide data for potential system integration contractors. This paper describes the most recent test results from the STC RemoteGen™ 55 W-class Stirling generators . Comparisons are made between the new data and previous Stirling thermodynamic simulation models. Performance-mapping tests are presented including variations in: internal charge pressure, cold end temperature, hot end temperature, alternator temperature, input power, and variation of control voltage.

“…The salient features of the free-piston Stirling power convertor and the measures taken in the design and development to enhance reliability have been described in earlier publications. 2 The specific Stirling convertor being transitioned for potential flight applications is the Technology Demonstration Convertor (TDC) that has been developed by the Stirling Technology Company of Kennewick, WA. 3 The reliability of the TDC that would use the nominal 250 W of heat provided by a GPHS module is being quantified under the GRC technology development efforts (note that all current design and test activities are carried out using nonnuclear, surrogate heat sources).…”
