For most applications the space power system requirements are characterized by a high conversion efficiency, long and reliable maintenance-free operation, relatively low mass and volume, perfect dynamic balance. The system discussed is a Stirling engine incorporating refractory metals for the hot parts to permit a high conversion efficiency and a helium or hydrogen light gas working fluid for high speed, high power density. A novel kinematic mechanism called the Ross linkage is included in the engine. This eliminates piston side forces, a principal cause of seal wear and the consequent limit to operating life of reciprocating systems, permits an unusually compact engine arrangement that can be easily balanced and which lends itself well to multiple cylinder arrangements wherein a small number of basic components can be assembled into a family of dynamic space power systems embracing a wide power range.
