Abstract
A landing gear includes a wheel support portion connected to a fuselage of an aircraft, a wheel rotatably connected to the wheel support portion via a shaft, a stator mounted on the shaft, and a rotor mounted on the wheel spaced apart from the stator.
Claims6
A method for takeoff and landing of an aircraft, the aircraft including a plurality of landing gear, wherein each of the plurality of landing gear comprises a plurality of wheels each having an in-wheel motor therein and a control unit configured to control driving of the plurality of wheels, the method comprising:
- taxiing, by the aircraft, up to a runway by receiving auxiliary thrust from a motor positioned in the wheel;
- running, by the aircraft, on the runway and taking off by receiving main thrust from an engine or propulsion motor, together with the auxiliary thrust;
- and
- running, by the aircraft, on the runway while performing regenerative braking controlled by the controller and using the in-wheel motor immediately after touching down on the runway;
- wherein the controller provides power generated by regenerative braking of a forward wheel of the plurality of wheels to an in-wheel motor of a backward wheel of the plurality of wheels, and controls the backward wheel to rotate in reverse;
- or
- wherein the controller provides power generated by regenerative braking of a backward wheel of the plurality of wheels to an in-wheel motor of a forward wheel of the plurality of wheels, and controls the forward wheel to rotate in reverse.
A method for takeoff and landing of an aircraft, the aircraft including a plurality of landing gear, wherein each of the plurality of landing gear comprises a plurality of wheels each having an in-wheel motor therein and a control unit configured to control driving of the wheels, the method comprising:
- taxiing, by the aircraft, up to a runway by receiving auxiliary thrust from the in-wheel motor positioned in the wheel;
- running, by the aircraft, on the runway and taking off by receiving main thrust from an engine or propulsion motor, together with the auxiliary thrust;
- and
- running, by the aircraft, on the runway while performing regenerative braking controlled by the controller and using the in-wheel motor immediately after touching down on the runway:
- wherein braking of the wheel is performed by the controller applying power for rotation in reverse to a plurality of wheels such that the in-wheel motor acts in a direction opposite to a direction of rotation of the plurality of wheels.
