The invention discloses a device and method for improving the parachute opening reliability of an ejection seat lifesaving parachute, and relates to the field of air-drop. The device for improving the parachute opening reliability of the ejection seat lifesaving parachute comprises a lifesaving parachute box and a brake parachute box which are installed on an ejection seat and connected with each other, the brake parachute box is configured to be capable of being separated from the lifesaving parachute box, the lifesaving parachute is arranged in the lifesaving parachute box, and a connecting belt, the brake parachute and a constant force snapping rope are arranged in the brake parachute box. One end of the connecting belt is connected with a parachute rope of the brake parachute, the other end of the connecting belt is connected with the top of the escape parachute box, and one end of the constant-force snapping rope is connected with the top of a parachute canopy of the brake parachute. The device and method for improving the parachute opening reliability of the ejection seat lifesaving parachute solve the problems that parachute cords and parachute canopies are bent in the high-speed ejection process of an ejection seat, the problems that the lifesaving parachute is inflated in advance, damaged seriously, turned over locally and the like are solved, potential safety hazards caused by interference after a parachute box and the lifesaving parachute are separated are avoided, and the service life of the lifesaving parachute is prolonged. And the high-speed working reliability of the escape parachute matched with the ejection seat is improved.

    一种提升弹射座椅救生伞开伞可靠性的装置及方法,涉及空投领域。提升弹射座椅救生伞开伞可靠性的装置包括安装于弹射座椅上且相互连接的救生伞箱和减速伞箱,减速伞箱被配置成可与救生伞箱分离,救生伞箱内设有救生伞,减速伞箱内设有连接带、减速伞和定力拉断绳,连接带的一端连接减速伞的伞绳,另一端连接救生伞箱顶部,定力拉断绳的一端连接减速伞的伞衣顶部,另一端连接减速伞箱顶部。提升弹射座椅救生伞开伞可靠性的装置及方法解决了弹射座椅在高速弹射过程中产生的伞绳和伞衣弯曲现象,避免出现救生伞提前充气、破损严重以及局部翻伞等问题,避免伞箱与救生伞分离后干涉带来的安全隐患,提高弹射座椅配套救生伞的高速工作可靠性。
