METHOD AND SYSTEM FOR CONTROLLING LONGITUDINAL MOVEMENT DURING TAKEOFF ON FLIGHT STRIP AND CLIMBING OF UNMANNED AERIAL VEHICLE WITH SPECIALLY ARRANGED FRONT AND REAR WINGS Russian patent published in 2019 - IPC B64C39/08 B64C13/00 G05D1/00 

FIELD: aviation; control systems.

SUBSTANCE: group of inventions relates to a method and a system for controlling the trajectory long run on a flight strip and a climbing of the unmanned aerial vehicle (UAV) with the front and rear wings articulated on the keel. To implement the method, based on the results of preliminary simulation of UAV longitudinal movement in the calculation unit, analytical dependencies and values of all parameters required during model testing are generated, required parameters are measured and selected to smooth rudder oscillations and avoiding short-term detachments from the flight strip, which ensures fast climb when sufficient lifting force is achieved. Control system comprises in-series correcting links of steering contours wheels of front and rear wings. Contour of rear wing rudders control comprises measurement unit, oscillating link, nonlinear link with linearity zone and angular speed limitation, differentiating link, adder, aperiodic link, nonlinear link with linear zone and rudder height limitation. Contour of rudders control of front fenders includes unit of calculations, contour compares link by angle of attack, amplifier by angle of attack, adder, aperiodic link, nonlinear link with linear zone and rudder limitation height, connected in certain manner.

EFFECT: higher AC stability at flight strip run area and climbing.
