摘　　要：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。This paper discusses some typical auto landing methods.Then it analyze advantages of the deep stall landing and puts forward a deep stall landing method for a small electric-powered UAV,which wing load is small.The deep stall state equation is educed based on analysis of the UAV dynamics model with high angle of attack.At last the deep stall landing model is built and simulated in Matlab/Simlink.The simulation results indicate that the deep stall landing for a small electric-powered UAV is feasible after choosing appropriate stall altitude.
