Title:
ROCKET CONTROL SYSTEM AND METHOD OF CONTROLLING LANDING OPERATION OF ROCKET
Document Type and Number:
WIPO Patent Application WO/2022/014694
Kind Code:
A1
Abstract:
The present invention provides a method of controlling a horizontal translational motion of a rocket without changing the posture of an aircraft and without increasing manufacturing costs or operating costs, to thus accurately execute a landing operation of the rocket. This rocket control system comprises: a gimbal actuator that controls a steering angle of a gimbal mechanism located below the center of gravity of a body of the rocket; a fin actuator that controls a steering angle of a posture control fin located above the center of gravity of the body of the rocket; a measurement unit that measures a physical quantity related to the movement of the body of the rocket; and a control unit that controls the gimbal mechanism and the posture control fin according to the measurement result from the measurement unit to control the horizontal translational motion of the rocket.
