The invention relates to the technical field of aerospace equipment and discloses an escape device for a helicopter. The device comprises a helicopter body and a machine chair installed in the helicopter body, the machine chair is movably connected with the helicopter body through a limiting rod, a fixing device for binding passengers is arranged on the machine chair, and a buffering air bag capable of expanding quickly is arranged at the bottom of the machine chair. Escape device for helicopter, during forced landing, under the action of the buffer air bag; impact force borne by passengers inthe cabin when the cabin touches the ground is greatly reduced; mITIGATING INJECTION TO OCCUPANT, the survival probability of personnel in the forced landing time is improved; meanwhile, when the helicopter falls into water, the buffering air bag can be drawn out for floating, and when the falling height of the helicopter is high, passengers in the helicopter can be pulled out in an inclined modethrough a parachute, so that accidental injuries of rotor wings are avoided, on one hand, the survival rate of high-altitude parachute passengers is increased, and on the other hand, multiple personscan escape at the same time through landing buffering of the buffering air bag.
本发明涉及航天航空设备技术领域,且公开了一种直升机用逃生装置,包括直升机本体和安装与直升机本体内的机椅,所述机椅通过限位杆与直升机本体活动连接,所述机椅上设有绑紧乘员的固定装置,所述机椅的底部设有可快速膨胀的缓冲气囊。该直升机用逃生装置,迫降时,在缓冲气囊的作用下,大大减少了触地时机舱内乘员受到的冲击力,减轻乘员受到的伤害,提高迫降时机内人员的生存几率,同时当直升机坠落到水里时,缓冲气囊可抽出用于漂浮,当直升机的坠落高度较高时,可通过降落伞的形式将机内乘员斜拉出,避免旋翼误伤,一方面,高空伞降乘员的生存率,另一方面,通过缓冲气囊的落地缓冲,可提供多人同时逃生。
