The invention discloses a tethered air-drop landing buffering device driven by an air cylinder, and relates to the field of air-drop buffering. And the steel wire rope is quickly retracted through combination of stretching movement of the air cylinder and the distance-multiplying structure, so that landing buffering of materials is realized. According to the technical scheme, the rope-tied air-drop landing buffering device comprises a structure body connected with a parachute, an air cylinder fixedly installed on the structure body and a steel wire rope connected with the air cylinder through a distance doubling structure. The objective table is hung through a steel wire rope, the landing legs are installed on the bottom face of the objective table, and the explosive bolts are installed between the landing legs. After the explosive bolt explodes regularly, the landing leg freely swings downwards, the mandrel freely stretches out, and when the acceleration change of the mandrel is larger than a preset threshold value, the cylinder rod of the air cylinder is controlled to stretch out upwards to lift the objective table through the steel wire rope. The invention has the advantages of compact structure, light weight, low cost, high reliability and the like, and adapts to the lightweight demand of small airdrop soft landing.

    本发明公开了一种气缸驱动的绳系空投着陆缓冲装置,涉及空投缓冲领域。通过气缸伸出运动与倍距结构的结合快速收起钢丝绳,实现物资的着陆缓冲。本发明的技术方案为:所述绳系空投着陆缓冲装置包括连接降落伞的结构主体,固定安装在结构主体上的气缸,通过倍距结构连接气缸的钢丝绳,通过钢丝绳吊挂的载物台、安装在载物台底面上的若干着陆腿以及安装在各个着陆腿之间的爆炸螺栓;爆炸螺栓定时爆炸后,着陆腿自由下摆,芯轴自由伸出,当芯轴的加速度变化大于预设阈值时,控制气缸缸杆向上伸出经钢丝绳提升载物台。本发明具有结构紧凑、重量小、成本低、可靠性高等优点,适应小型空投软着陆的轻量化需求。
