The invention relates to the technical field of aircraft recovery, in particular to a fixed-wing unmanned aircraft net collision recovery device which comprises a support, a recovery net, four speed reduction dragging ropes and four damping output mechanisms, four pulleys are installed on the support, one end of each speed reduction dragging rope is connected to the corresponding damping output mechanism, and the other end of each speed reduction dragging rope is connected to the corresponding damping output mechanism. The recovery device further comprises two net stretching traction ropes arranged on the front side of the recovery net, one ends of the two net stretching traction ropes are connected with the left side portion and the right side portion of the recovery net respectively, and the other ends of the two net stretching traction ropes are fixedly arranged relative to the ground. The two net tensioning traction ropes and the four speed reduction dragging ropes are all in a tensioning state, and the recovery net is suspended in the air in a '>' shape. According to the recycling device, a large recycling net can be adopted, the lower middle portion of the recycling net can be prevented from drooping, the good wrapping and restraining effect is guaranteed, meanwhile, the net stretching supporting rods are low in height, and the device structure is more compact and simplified.
本发明涉及飞行器回收技术领域,具体涉及一种固定翼无人飞行器撞网回收装置,包括支架、回收网、四根减速拖曳绳及四个阻尼输出机构,支架上安装有四个滑轮,四根减速拖曳绳的一端分别连接在各阻尼输出机构上,另外一端绕过相应滑轮后分别与回收网的四个角部对应连接,回收装置还包括设置于回收网前侧的两根张网牵拉绳,两根张网牵拉绳的一端分别与回收网的左侧部和右侧部连接,另外一端相对地面固定设置,两根张网牵拉绳及四根减速拖曳绳均处于张紧状态,回收网呈“>”形悬置于空中。本发明的回收装置可以采用较大的回收网,且可避免回收网的中下部呈耷拉状态,保证较好的包覆约束效果,同时张网支撑杆高度低,装置结构更为紧凑简化。
