摘　　要：运载火箭空中回收的挂取过程是整个回收过程中最关键的环节之一。针对运载火箭尾舱空中挂取的全流程,开展了将直升机作为回收平台的钩取装置设计,主要包括拉力传感器、过载保护装置、减载装置以及末端的执行机构。翼伞和减速伞从火箭尾舱的底部弹出,挂取装置可通过挂取翼伞顶部的牵顶伞实现对回收体的挂取操作。通过对挂取过程的仿真分析可以看出,回收体的质量增大时,过载显著增加,而当翼伞的收伞时间增加时,减载效果明显。The hanging process is one of the key links in the Mid-Air retrieval of launch vehicle.According to the whole process of the launch vehicle tail cabin hanging in the air,the design of the hanging device based on the helicopter as the recovery platform is carried out.The hanging device includes tension sensor,load shedding device,overload protection device and the actuator in the end of the hanging device.Parafoil and parachute eject from the bottom of the tail cabin of launch vehicle.The hanging device can realize the hanging operation of the retrieval by hanging attached apex drogue on the top of parafoil.Through the simulation analysis of the hanging process,it can be seen that when the weight of the retrieval increases,the overload increases significantly.When the parachute retraction time increases,the load reduction effect is obvious.
