摘要
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。
To land UAV safely, a kind of parachute recovery system for the UAV is designed in this paper. Analysis of the recovery system lids under aerodynamic load and the suspension structure under parachute re- leasing overload are completed by finite element simulation. The parachute releasing test of this system is de- signed and completed. The results show that the structural design can satisfy both the strength and the relia- bility requirements of parachute releasing.
