High Pressure Intercooled Turbine Engine Concept 881204

A study was conducted to assess the feasibility of an advanced technology High Pressure Intercooled Turbine (HIPIT) engine for prime propulsion applications. A cycle performance analysis was conducted for a hypothetical HIPIT gas turbine sized to deliver 1000 hp output with and without a reheat combustor. Selection of candidate designs with an overall compressor pressure ratio of 41.7 were predicted to have respective specific fuel consumptions of 0.358, and 0.434 lb/hp.hr with corresponding weights of 503 lb., and 374 lb.Three conceptual HIPIT engine preliminary mechanical design configurations were studied, and part load performance characteristics of the HIPIT are also presented.As a result of the high pressure ratio, reheating was predicted to provide a power boost of 35%, ideal for emergency power demands.
