Abstract:The Stirling engine power conversion concept is a candidate to provide electrical power for deep space missions. A key element for qualifying potential flight hardware is the long-term durability assessment for critical hot section components of the power converter. One such critical component is the power converter heater head, which is a high-temperature pressure vessel that transfers heat to the working gas medium of the converter. Rhenium is a candidate material for the heater head application because of i… Show more
