Unmanned helicopter air-drop descent control device

The invention provides an air-drop descent control device of an unmanned helicopter. The air-drop descent control device comprises a mounting frame, an air-drop device, a cable reel, a descent control device body, a load frame and an anti-swing device. The air-drop box is connected below the load frame, the air-drop device is an action actuator, and the descent control device enables the materials to slowly descend to protect the materials and drop the materials to a destination at a fixed point; by means of the descent control device, the anti-swing device and the air-drop box, the technical problems that when an existing unmanned helicopter and an existing unmanned aerial vehicle drop device are used, the drop mode has large errors, fixed-point accurate drop is difficult to conduct, and materials are damaged due to a certain probability are solved. 本发明提供一种无人直升机空投缓降器，包括：安装架、空投器、线缆盘、缓降器、载荷架、防摆器；载荷架下方连接空投箱，空投器为此发明的动作执行器，缓降器使物资缓慢下降达到保护物资且定点投放到目的地；通过缓降器防摆器以及空投箱，解决了现有无人直升机及无人机的投放装置时，投递方式有较大的误差，很难进行定点精准的投放，且有一定的几率
