This paper presents progress on the Advanced Stirling Convertor (ASC) being developed by Sunpower and Boeing/Rocketdyne under NASA NRA funding. The ASC will use a high temperature heater head to allow for operation at 850 °C. The ASC is projected to have an efficiency approaching 40% (AC electrical out/ heat in) when operating at a temperature ratio of 3.0, and to have a convertor specific power of 90 We/kg (AC). An early developmental unit, the Frequency Test Bed (FTB) convertor, has already demonstrated 36% efficiency (based on AC electrical out) at this temperature ratio. The ASC is being developed for potential use in advanced radioisotope space power systems. The increased efficiency of this Stirling convertor compared to RTGs, would reduce the required amount of Plutonium fuel by a factor of approximately 5.
