摘要
提出了无人机回收缓冲气囊设计的新构思,采用压缩空气充气和从环境获取空气相结合的方法填充气囊。对气囊的结构形式、进排气口的设计、排气口面积的计算、缓冲过程的计算和气囊体积的计算等问题进行了讨论,并制定了相关的试验方案。这种新型自充气囊如果能够实现,则可大幅度降低整个缓冲气囊系统的重量,在无人机回收技术上实现突破。
A new design for the cushion airbag of the unmanned aerial vehicle recovery is presented. The airbag is charged by both the compressed air and the air from the environment. The structure pattern of the airbag, the design of the inlet and the outlet, the area calculation of the air outlet, the calculation of the cushion process and the airbag volume are discussed. And a related experimental scheme is established. If this kind of new self-inflating airbag can be made, the weight of the whole cushion airbag system can be reduced. Thus, the unmanned aerial vehicle recovery technique will have a breakthrough.
