SWITCHED RELUCTANCE MACHINES FOR GAS TURBINE STARTER/GENERATORS, FUEL PUMPS AND FLIGHT CONTROL ACTUATORS

The project proposed involves the detailed design, thermal analysis and performance simulation of Switched Reluctance electric machines for principle applications for the More-Electric-Aircraft. Considerable published data for gas turbine electric accessory motors has been addressed to base line applications for trade study analysis. The effort proposed for this project is more specific as related to actual applications such as being considered for the ATF programs (actuators and pumps) and disposable high speed gas turbines (starter/generators). The work would compare 3, 4 and 5 phase SR machines for each application, make a selection and perform a detailed design for each. Actual engine, pump and actuator vendors would be used for collaboration and integration of SR machine designs into actual engines, pump and actuators selected. The intent of the design study would be to select existing or future applications using a specific engine and specific pumps to develop an accurate sizing using thermal modeling, static simulation and dynamic simulation. The resulting designs would be considered for actual hardware fabrication and testing in a Phase II program in conjunction with engine and pump vendors. The SR machines for these MEA applications could then be considered as available hardware for applications.
