System evaluation of advanced technology gas turbines for naval ship propulsion
A system design study was conducted to determine the performance characteristics of future aircraft-derivative gas turbine systems suitable for naval ship propulsion applications. Gas turbines representing next-generation aircraft engine technology were reviewed, and candidates for potential use as regenerative-cycle or advanced simple-cycle propulsion units were selected. Part-power performance characteristics and preliminary design features were determined, and various combinations of the candidate engines were compared to establish fuel consumption characteristics over representative combat ship duty cycles. Fuel savings as high as 50% were demonstrated for a propulsion plant consisting of one modified PW2037 regenerative-cycle engine and one PW2037 simple-cycle engine. The LM2500 marine gas turbine was used as a reference, representing naval propulsion plants currently in service.
