Title:
POWER SYSTEM OF ELECTRIC PROPULSION ROTARY WING AIRCRAFT, AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/238047
Kind Code:
A1
Abstract:
A power system of an electric propulsion rotary wing aircraft, and a control method therefor. The power system of an aircraft comprises a fusion energy storage system, a brushless direct current motor speed regulator, a brushless direct-current motor, propellers mounted on the brushless direct current motor, a flight control computer, an aircraft inertial sensor, a height sensor and a remote control signal receiver. The power system of an electric propulsion rotary wing aircraft can predict power requirements of an aircraft, so as to achieve good management of the power output of the energy storage system. The control method for the power system can satisfy the real-time power requirement and power reserve requirement of the aircraft by using a power system having a lower weight, and the control method for the power system can also prolong the service life of an energy system, so as to improve the safety, maneuverability and endurance of the aircraft.
