Problems solved by technology

2. The thrust-to-weight ratio of the aircraft is far less than 1, and the acceleration performance of the UAV is poor
3. The overload impact during the ejection process is likely to cause deviations in the attitude measurement of the UAV
4. After ejection, before the folding wings are fully deployed, the anti-interference ability of the UAV is poor
Therefore, after the UAV is ejected, it is very prone to problems of height drop and stall

Abstract

The invention provides an ejection takeoff control method for an unmanned aerial vehicle with large overload and foldable wings and relates to the technical field of unmanned aerial vehicles. By meansof the method, the unmanned aerial vehicle with the large overload and the foldable wings can be smoothly ejected and take off, and correspondingly the problem of takeoff failure caused by height reduction, stalling and the like of the unmanned aerial vehicle is avoided. The method comprises the following steps of S1, ejection takeoff preparation and overload detection; S2, attitude and power control; S3, control of airspeed and climbing rate; S4, altitude climbing control. The provided technical scheme is suitable for an ejection takeoff process of the unmanned aerial vehicle with the largeoverload and the foldable wings.

Description

【Technical field】 [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a control method for ejection and take-off of a large-overload, folding-wing unmanned aerial vehicle. 【Background technique】 [0002] UAV ejection take-off control is used for the state stability and state transition control of the UAV during the large overload and high dynamic ejection process. Through the rudder surface and power control, the flight state of the aircraft attitude, airspeed, and altitude can be kept controllable to achieve The goal of a smooth transition of the UAV from the pre-ejection state to the normal cruising state. [0003] At present, the catapult take-off method of UAV is mainly based on the slide rail catapult take-off method. This ejection method is to place the aircraft on a slide rail at a certain angle to the ground. The angle is generally set as the trim elevation angle when the aircraft climbs. The UAV is driven by releasing c...
