Title:
METHOD AND COMPUTER PROGRAM FOR CONTROLLING TILT ANGLE OF MAIN ROTOR ON BASIS OF VERTICAL ATTITUDE CONTROL SIGNAL LOW-SPEED FLIGHT STATE, AND VERTICAL TAKE-OFF AND LANDING AIRCRAFT
Document Type and Number:
WIPO Patent Application WO/2019/124686
Kind Code:
A1
Abstract:
A flight controller of a vertical take-off and landing aircraft, according to one embodiment of the present invention, controls a tilt angle of a main rotor on the basis of a vertical posture control signal in a low-speed flight state. When a control signal of the vertical take-off and landing aircraft including a vertical attitude control signal for changing the pitch attitude of the vertical take-off and landing aircraft by a first pitch attitude is obtained, the flight controller according to the present invention may determine the tilt angle of the main rotor with reference to the first pitch attitude, and generate a tilt angle control signal of the main rotor on the basis of the determined tilt angle.
