为实现无人机的安全回收,文中针对某型号无人机设计了一种伞降回收系统,采用有限元法进行了回收系统口盖在气动力作用下及挂点在开伞过载作用下的力学分析,设计并完成了该回收系统的抛伞实验。结果表明:该回收系统可以在满足结构强度要求的情况下同时满足开伞的可靠性要求。
In order to achieve the safe recovery of the UAV, an umbrella parachute recovery system is designed for a UAV. The finite element method is used to recover the flap of the system under the action of the aerodynamic force and the hanging point under the overload of the parachute Mechanical analysis, design and completion of the recycling system of the umbrella test. The results show that the recovery system can satisfy the reliability requirements of the parachute at the same time while meeting the structural strength requirements.
