Title:
ROCKET-BOOSTED LAUNCH AND TAKEOFF CONTROL METHOD FOR UNMANNED AERIAL VEHICLE HAVING FLYING-WING LAYOUT
Document Type and Number:
WIPO Patent Application WO/2023/240862
Kind Code:
A1
Abstract:
The present invention relates to the technical field of aviation flight control. Disclosed is a rocket-boosted launch and takeoff control method for an unmanned aerial vehicle having a flying-wing layout. The method is applicable to the control over a rocket-boosted launch and takeoff process of an unmanned aerial vehicle having a flying-wing layout. A control method that combines elevator pre-provision and pitch angle control is applied to a longitudinal controller, such that an aircraft is dynamically stable in the longitudinal direction at a launch and takeoff stage; roll angle control is applied to a transverse controller, such that wings are maintained flat, and after the aircraft climbs to a safety height, switching to flight trajectory tracking is performed; and a speed-based stability-augmentation softening factor is designed for a heading controller, such that an unmanned aerial vehicle is prevented from adverse disturbance caused by a rudder that is generated by low-speed angle-of-sideslip stability augmentation, and it is ensured that the unmanned aerial vehicle accesses stability augmentation control at a high-speed stage. The present invention is applicable to takeoff control over an unmanned aerial vehicle, which has a flying-wing layout and takes off on the basis rocket boosting.
