The invention discloses a ring-shaped combined buffer airbag system based on Miura folded paper. The airbag system comprises a plurality of mutually independent ring-shaped airbags, a pressing and releasing device, a one-way valve, an exhaust hole controller and an inflating device. According to the air bag system, the landing buffering requirement of an aerospace returner in the shape of a wave rider is met, the folded buffering air bag is arranged on the side face of the returner, and the buffering air bag can be unfolded without throwing away the large bottom of the returner. The buffering air bag clings to the outer surface of the returner, so that the buffering process of the returner is safer and more efficient. Meanwhile, the air bag is easy to fold and unfold by adopting a paper folding mode. In addition, the landing buffering air bag can monitor changes of the air pressure and the speed in real time, and accurate control over the inflation process and the exhaust process of the buffering air bag is achieved by controlling a one-way valve and an exhaust hole controller.

    本发明公开了一种基于Miura折纸的圆环状组合型缓冲气囊系统,所述气囊系统包括若干互相独立的圆环状气囊、压紧释放装置、单向阀门、排气孔控制器和充气装置。本发明气囊系统满足了乘波体外形的空天返回器的着陆缓冲需求,折叠后的缓冲气囊布置在返回器的侧面,不需要抛去返回器的大底即可展开缓冲气囊。由于缓冲气囊紧贴返回器外表面,使得返回器的缓冲过程更加安全高效。同时采用折纸样式,使气囊易于折展。此外该着陆缓冲气囊能够实时监测气压和速度的变化,并通过控制单向阀门、排气孔控制器来实现缓冲气囊充气和排气过程的精准控制。
