Abstract :
The development of a Stirling engine-powered, 3 kW electric generator set is discussed. The generator set contains two high-frequency (115 Hz), helium-charged, free-piston Stirling engines mounted in an opposed configuration and heated by gas-fired sodium heat pipe, a power conditioner, an adaptive load controller, and the engine cooling system. The maximum power from a single engine, at this stage of development, is 2.1 kW(e) with an efficiency of 19% (engine/alternator). The maximum engine efficiency is 23%. The engine mass of 28 kg results in a low mass per unit power of 13.3 kg/kW
