Abstract
A parallel hybrid-electric aircraft engine that provides power for takeoff and climb by combining the output power of an electric motor with that an internal combustion engine and then converting the electric motor to a generator once the additional power of the electric motor is no longer needed.
Claims4
A method for takeoff and climb in an aircraft comprising:
- powering a first mechanical-rotary shaft using a first internal combustion engine;
- powering a first electrical-rotary shaft using electrical power stored in any one of an electricity storage device and via connection to the first mechanical-rotary shaft;
- connecting a sprag clutch around the mechanical-rotary shaft and connecting a belt from the sprag clutch to the first electrical-rotary shaft;
- applying to the takeoff and climb at least a portion of a thrust generated by the first mechanical-rotor;
- selectively applying to at least the takeoff and climb, as well as cruise altitude, in parallel with the first mechanical rotary shaft, at least a portion of a thrust generated by the first electrical-rotary shaft by selectively engaging and disengaging the sprag clutch with the mechanical-rotary shaft.
