Overview of NASA Lewis Research Center free-piston Stirling engine technology activities applicable to space power systems. [Jack G Slaby; United States. National Aeronautics and Space Administration.]. An overview is presented of the National Aeronautics and Space Administration (NASA) Lewis Research Center free-piston Stirling engine activities directed toward space-power application. Free-piston Stirling technology is applicable for both solar and nuclear powered by: 9.   Free-Piston Stirling Engines (FPSEs) have recently attracted attention as a promising energy conversion technology because of their desirable characteristics such as high efficiency, high reliability, and easy and quiet operation.

Free Piston Stirling Engines The story of a novel remote power solution wasn’t the only change that was needed to prepare the Stirling Cycle technology for remote power generation,” said Isaac Garaway, PhD, Chief Technology Officer for Qnergy. stages of planning for their proposed Deep Space Missions. There were many needs to be. Abstract: MTI recently completed an initial technology feasibility program for NASA by designing, fabricating and testing a space power demonstrator engine (SPDE). This program, which confirms the potential of free-piston Stirling engines, provided the major impetus to initiate a free-piston Stirling space engine (SSE) technology program. Free-piston Stirling engines (FPSE) have no rotating parts. In the majority of cases, output power is taken from a linear (usually permanent magnet) alternator attached to the piston, while the displacer is actuated by the pressure variation in the space beneath the piston. Free piston Stirling Engine technology was pioneered by NASA in space. Unlike other technologies there is no reliability reduction for multiple start-stops or continuous operation. Design life for commercial applications is conservatively estimated at 60, hours with zero maintenance!

Overview of free-piston Stirling engine technology for space power application An overview is presented of free-piston Stirling engine activities, directed toward space power applications. One of the major elements of the program is the development of advanced power conversion.   The first generation of hardware in the Large Free-Piston Stirling Engine ( kW per cylinder) program, shown above, was the Space Power Demonstrator Engine (SPDE). The SPDE was a free-piston Stirling engine coupled to a linear alternator. It was a double cylinder, opposed-piston convertor designed to produce 25 kWe at 25% overall efficiency. A free piston engine is another type of reciprocating engine, one that does not have a crankshaft of any mechanical constraint on the motion of its piston (s). The engines are often simple and potentially more efficient than crankshaft engines but they are more difficult to engineer and exploit successfully. View chapter Purchase book. The Stirling cycle offers an attractive power conversion concept for space power needs. Discussed here is the completion of the Space Power Demonstrator Engine (SPDE) testing-culminating in the generation of 25 kW of engine power from a dynamically-balanced opposed-piston Stirling engine at a temperature ratio of
