초록

A turbofan gas turbine propulsion engine includes a multi-speed transmission between the high pressure and low pressure turbines and associated high pressure and low pressure starter-generators. The multi-speed transmission reduces the operating speed range from the low pressure turbine to its associated starter-generator, and is configurable to allow the starter-generator associated with the low pressure turbine to supply starting torque to the engine.

청구항

We claim: 1. A multi-spool gas turbine engine, comprising: a gas turbine engine including at least a high pressure turbine and a low pressure turbine, each turbine adapted to receive a flow of combusted gas and operable, upon receipt thereof, to generate rotational energy; a high pressure starter-generator coupled to the high pressure turbine and configured to selectively operate in either (i) a generator mode, in which at least a portion of the rotational energy generated by the high pressure turbine is converted to electrical energy or (ii) a motor mo...
