Abstract
An electric aircraft includes system for operating the aircraft. The electric aircraft includes a wing having a first control surface, a second control surface, a battery and a gearbox mechanically coupled to the first control surface. The first control surface is operated, and a voltage is induced from mechanical energy generated during a deceleration of the first control surface that occurs while operating the first control surface, wherein an airflow across the first control surface causes the deceleration. The induced voltage can be stored at the battery or used to operate the second control surface using the induced voltage.
Claims14
A method of operating an electric aircraft, comprising:
- operating a first control surface on a wing of the electric aircraft;
- generating an induced voltage from mechanical energy generated during a deceleration of the first control surface that occurs while operating the first control surface, wherein an airflow across the first control surface causes the deceleration;
- operating a second control surface on the wing using the induced voltage;
- and
- rotating a rotor shaft in a gearbox from mechanical energy, the rotor shaft including an armature rotatable within a stator coil for generating the induced voltage.
A system for operating an electric aircraft, comprising:
- a first control surface on a wing of the electric aircraft;
- a second control surface on the wing;
- a battery;
- and
- a gearbox mechanically coupled to the first control surface, wherein the gearbox is configured to generate an induced voltage at the battery from mechanical energy generated during a deceleration of the first control surface due to an airflow across the first control surface and operate the second control surface using the induced voltage.
