An engine power extraction control system controls the main propulsion engines and the electrical machines that are coupled thereto to supply an appropriate amount of aircraft thrust and electrical energy to the aircraft. The engines and electrical machines are also controlled so that the propulsion thrust that is generated is split between the various turbines in the main propulsion engines to maintain an adequate surge margin and to minimize residual thrust generation.
I claim: 1. An engine power extraction control system for an aircraft, 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 first generator coupled to receive at least a portion of the rotational energy generated by the high pressure turbine and operable, upon receipt thereof, to generate electrical energy; a second generator coupled to receive at least a portion of the rotational...
