Abstract:

Ramgen Power Systems, Inc. RPS is developing two high efficiency gas turbine engine concepts that combine many of the proven features of supersonic compression and expansion systems, commonly used in supersonic flight inlet and nozzle designs, with conventional axial flow turbo-machinery practices to create two entirely new gas turbine engines. The superior efficiency is a result of high pressure shock wave compression and supersonic expansion phenomena to produce high component efficiencies, and a unique engine configuration that minimizes flow stream turning losses throughout the engine. The RPS engine concept can be configured as a high pressure ratio simple-cycle design for propulsion applications, or as a low pressure ratio recuperated engine either as a standalone component or combined with a hybrid fuel cell for stationary power applications. The anticipated compression and expansion efficiencies, decreased footprint, and reduced part count of the RPS technologies promise revolutionary new power generation and propulsion systems with decreased heat signatures resulting from lower exhaust temperatures. These unique aerodynamic features will open new options for engine designers and package integrators. This report documents research and development of the RAMGEN technology and potential applications toward military operations including warfighter applications.
