Heat Regenerative System for T53 Shaft Turbine Engines

摘要

A heat regenerator was designed to demonstrate the feasibility of regeneration for the T53 shaft turbine engine. Parameters of the initial design, a multiwave plate type, were optimized to provide a 27-percent fuel savings at 75 percent normal rated power. Test core modules leaked beyond the 0.25-percent flow-rate limit. Consequently, effort was directed toward a conventional tube-type regenerator, which was designed to provide a 24-percent fuel savings at 75 percent normal rated power. The tube-type regenerator and the interface hardware were fabricated and integrated with the engine, and the system is ready for testing. (Author)
