An air vehicle incorporating a hybrid propulsion system. The system includes a gas turbine engine as a first motive power source, and one or more battery packs as a second motive power source. Through selective coupling to a DC electric motor that can in turn be connected to a bladed rotor or other lift-producing device, the motive sources provide differing ways in which an aircraft can operate. In one example, the gas turbine engine can provide operation for a majority of the flight envelope of the aircraft, while the battery packs can provide operation...
1. A method of providing motive power to a rotary-winged aircraft, said method comprising: coupling a hybrid propulsion system to a thrust producing device, said hybrid propulsion system comprising: a gas turbine engine;an electric storage device configured to deliver an electric current;an electrical generator responsive to said gas turbine engine such that power produced by the operation thereof is converted into electric current; andan electric motor selectively responsive to said electrical generator and said electric storage device; andoperating one...
