The invention relates to the technical field of spacecraft return landing, in particular to a cold air reverse thrust and air cushion buffer landing device for a manned spacecraft, which comprises a return capsule, a parachute mounted in the top of the return capsule, an air injection component mounted in the bottom of the return capsule, and a metal outsole fixedly connected to the bottom of the return capsule. A cavity is formed between the inner wall of the metal outsole and the bottom surface of the return capsule; the air injection assembly comprises an air supply part arranged in the bottom of the return capsule, the air supply part communicates with a plurality of spray pipes, and the spray pipes are arranged in the cavity. According to the invention, the gas in the gas supply part is sprayed out through the spray pipe, so that the gas sprayed out of the spray pipe not only can generate reverse thrust, but also can form supporting force in the cavity to perform an air cushion buffering effect on the reentry capsule when the metal outsole is close to the ground, the impulse of the reentry capsule can be effectively consumed, and the reentry capsule can be buffered and stably landed.

    本发明涉及航天器返回着陆技术领域,特别是涉及一种用于载人飞船的冷气反推和气垫缓冲着陆装置,包括返回舱,返回舱的顶部内安装有降落伞,返回舱的底部内安装有喷气组件,返回舱的底部固定连接有金属大底,金属大底的内壁与返回舱的底面之间形成空腔;喷气组件包括设置在返回舱底部内的供气部,供气部连通有若干个喷管,喷管设置在空腔内。本发明通过将供气部内的气体通过喷管喷出,使喷管喷出的气体不仅能够产生反推力,还能够在金属大底靠近地面时,使空腔内形成支撑力对返回舱进行气垫缓冲作用,能够有效消耗返回舱冲量,使返回舱能够得到缓冲并平稳着陆。
