次生气囊在无人机回收系统中的应用

次生气囊是一项可以应用于无人机伞降结合气囊缓冲回收的具有实用价值的技术措施.次生气囊利用无人机主气囊触地后瞬间排出的气体填充成形,实现对机翼部位的缓冲保护.本文对次生气囊的工作过程、力学模型和相关技术指标进行了分析,认为次生气囊对主气囊的工作不产生不利影响,不增加对气源的需求,对无人机增重的影响也很小,但却可以有效地增加对无人机着陆的缓冲效果.

Application of Second-Airbag to Unmanned Aerial Vehicle

The second-airbag is a technique measure with the practical value for the unmanned aerial vehicle landing by a parachute combined with the cushion airbag. The second-airbag is charged with the air letting out of the main airbag of the unmanned aerial vehicle when it reaches the ground. In this way, it can keep the aerofoil from impacts. In this paper, the working process, mechanics model and related technical indexs of the second-airbag are analyzed. It is considered that the second-airbag does not have negative effects on the function of the main airbag. It does not need to supply more sources of the air and has a little effect on the extra weight to the unmanned aerial vehicle. Thus, it can increase the cushion effect of unmanned aerial vehicle landing.
