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;
at least one thrust generating apparatus whose position is variable;
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 acquire the current position of the at least one thrust generating apparatus, determine required power indicating electric power supplied to the motor based on the current position of the at least one thrust generating apparatus, and determine the amount of the electric power stored in the battery and the electric power produced by the generator but not stored in the battery among the electric power supplied to the motor based on the determined required power.

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:
-
acquiring a current position of at least one thrust generating apparatus of the hybrid aircraft whose position is variable; determining required power according to a flight state based on the current position of the at least one thrust generating apparatus; and determining the amount of first electric power and the amount of second electric power among the electric power supplied to the motor that provides power to the at least one thrust generating apparatus based on the required power, wherein the first electric power comprises electric power stored in the battery from electric power produced by the generator using a power supplied by the engine, and the second electric power comprises electric power not stored in the battery from the electric power produced by the generator. - View Dependent Claims (20)
