FLIGHT CONTROL METHOD AND DEVICE AND AIRCRAFT

WIPO Patent Application WO/2021/035623

A1

Provided are a flight control method and device (41) and an aircraft (42). The method comprises: acquiring observation speed information, observation attitude motion state and target attitude motion state of an aircraft (42); in response to an instruction to switch from a working state of a fixed-wing power system (12) to a working state of a rotor wing power system (11), turning off a fixed-wing electric motor; generating, according to the target attitude motion state and the observation attitude motion state, a first control instruction for controlling a rudder surface and a second control instruction for controlling the rotor wing power system (11); controlling a rudder deviation angle of the rudder surface according to the first control instruction; determining, according to the observation speed information, a rotor wing power adjustment parameter (232); adjusting the second control instruction according to the rotor wing power adjustment parameter (232), so as to acquire an adjusted second control instruction; and controlling the rotor wing power system (11) according to the adjusted second control instruction. In this way, the risk and difficulty during the switching of the aircraft (42) can be reduced, and the reliability during the switching of the aircraft (42) is improved.
