摘 要:
针对小型无人机伞降回收的特点，研究了在无人机回收过程中，飞机及降落伞系统的运动轨迹及姿态。通过分析机伞间的力学关系，建立了机伞系统运动模型，并进行了仿真分析，给出了无风情况下回收运动的仿真结果。结果表明，系统能够满足无人机回收要求，可以决定最佳的回收参数，从而得到最优回收轨迹和姿态。[著者文摘]

Parachute Landing Recovery Motion Analysis for Unmanned Aerial Vehicle

Abstract:
This paper discusses the position and gesture of the recovery motion for a small UAV, analyzes the dynamic relation between the aircraft and the parachute, and establishes a mathematical model of the aircraft-parachute system during the parachute landing program. This model is simulated under conditions of no wind. Simulation results show that the system meets the requirement of UAV recovery. Then we can analyze the optimum recovery parameters, and get the optimum recovery position and gesture of the system.[著者文摘]
