Vertical take-off and landing aircraft using hybrid-electric propulsion system
First Claim
1. A hybrid aircraft comprising:
- an engine;
a generator configured to produce electric power using power supplied by the engine;
a battery configured to store the electric power produced by the generator;
a motor configured to receive at least one of the electric power stored in the battery and electric power produced by the generator but not stored in the battery and provide the power to at least one thrust generating apparatus; and
a controller configured to select either silence mode or normal mode, and determine the amount of electric power stored in the battery and the amount of electric power not stored in the battery among the electric power supplied to the motor, based on the selected mode,wherein, in the silence mode, the controller configured to supply only the electric power stored in the battery to the motor, andwherein, in the normal mode, the controller configured to supply electric power not stored in the battery to the motor.

Abstract
A vertical take-off and landing aircraft using a hybrid electric propulsion system includes an engine, a generator that produces electric power using power supplied by the engine, and a battery that stores the produced electric power. A motor receives the electric power stored in the battery and electric power produced by the generator but not stored in the battery and provides the power to a thrust generating apparatus. A controller selects either silence mode or normal mode, and determines the amount of electric power stored in the battery and the amount of electric power not stored in the battery from the electric power supplied to the motor. In the silence mode, the controller supplies only the electric power stored in the battery and controls a duration by adjusting output power of motor. In the normal mode, the controller supplies electric power not stored in the battery.

19. A method of controlling a hybrid aircraft, the method comprising:
-
selecting either silence mode or normal mode, wherein, the hybrid aircraft comprises a battery, an engine, a generator, at least one thrust generating apparatus and a motor, wherein, the battery configured to store electric power produced by the generator using power supplied by the engine, wherein, the motor configured to receive at least one of the electric power stored in the battery and electric power produced by the generator but not stored in the battery and provide the power to the at least one thrust generating apparatus, wherein, in the silence mode, the electric power stored in a battery is only supplied to the motor, and wherein, in the normal mode, the electric power not stored in the battery is supplied to the motor; and determining the amount of electric power stored in the battery and the amount of electric power not stored in the battery among the electric power supplied to the motor, based on the selected mode. - View Dependent Claims (20)
