Solar heat pipe Stirling research work has been in progress since 1987 as part of a space solar dynamic technology program in NAL. The purpose of our research work is to provide a design methodology for space-based free piston Stirling power generating system, with a future target of a 1kW solar power Stirling experimental demonstrator, capable of operating on the Japanese Experiment Module of Space Station Freedom to be constructed in the early 2000 years. To data hardware ground tests of hybrid Stirling engine with externally-controlled displacer, linear alternator with moving magnets; and sodium heat pipe have been performed to achieve more efficient and stable operations of NALSEM 125 engine and to evaluate thermal transport characteristics of sodium heat pipe models. Furthermore the next Stirling model design of NALSEM 500 has been completed, and is being tested in 1993. The NALSEM 500 design employs an annular type linear alternator and clearance seal of power piston to meet the requirements for high power and long life. Addressed in the present paper are future evolutions of the NAL heat pipe Stirling research activity, and some interesting results available from the current Stirling experimental work.
