对几种典型的小型无人机回收方式进行了比较,针对小型电动无人机翼载荷较小的特点,深失速回收方式具有明显优势,并给出了具体的深失速回收方案。通过分析大迎角情况下无人机的动力学模型,推导了在深失速情况下无人机的状态方程,建立了无人机深失速回收仿真模型,并以某型近程电动无人机为对象,在Matlab/Simulink中对深失速模型进行仿真验证。仿真结果表明,合理选择小型电动无人机失速高度,深失速回收方案是可行的。
Several typical small UAV recycling methods were compared. In view of the small electric unmanned aerial vehicle wing load characteristics, deep stall recovery method has obvious advantages, and gives a specific program of deep stall recovery. By analyzing the dynamic model of UAV at high angle of attack, the state equation of UAV at deep stall is deduced, and the simulation model of recovery from deep stall of UAV is established. Based on a certain type of short range UAV As the object, the simulation of deep stalling model was carried out in Matlab / Simulink. The simulation results show that it is feasible to select a small electric UAV stall height and deep stall recovery scheme rationally.
