RE-1000 free-piston Stirling engine update
A free-piston Stirling engine has been under test at the NASA Lewis Research Center test facilities. The tests performed over the past several years on the single cylinder engine were designed to investigate the dynamics of a free-piston Stirling engine. The data are intended to be used primarily for computer code validation. The tests designed to investigate the sensitivity of the engine performance to variations in working space pressure, heater and cooler temperatures, regenerator porosity, power piston mass and displacer dynamics have been completed at Lewis. In addition, some data were recorded with alternate working fluids. A novel resonant balance system for the engine was also tested. This report presents some preliminary test results of the tests performed at the NASA Lewis facility along with an outline of future tests to be run with the engine coupled to a hydraulic output unit. A description of the hydraulic output unit is given.
