The invention discloses an airplane forced landing safety device. The device comprises a fixing system, a switching system and a buffering system, wherein the fixing system is installed at the bottom of an airplane, the switching system can achieve the effect that one main wheel set or two main wheel sets make contact with the ground and slide on the ground, the buffering device is used for reducing impact and danger during forced landing of the airplane, safety during forced landing is improved through the multiple layers of buffering devices, and stability during forced landing is provided; switching can be carried out under different conditions, the buffer system is provided with a brake and an auxiliary wheel system, safety and stability can be further improved, the auxiliary wheel system can increase rolling between the wheel system and the ground and improve stability when impact force is too large, and the buffer system can extend out of a friction block to conduct dry friction with the ground; and the aircraft speed is rapidly reduced.

    本发明公开一种飞机迫降安全装置,包括固定系统、切换系统、缓冲系统。固定系统安装在飞机底部,切换系统能实现一个主轮组或两个主轮组与地面接触,在地面上滑行,缓冲装置的作用在于减少飞机迫降时的冲击和危险,通过多层缓冲装置来提升迫降时的安全性,以及提供迫降时的平稳性,可以针对不同的情况进行切换,缓冲系统设置有有刹车以及辅助轮系统,能够进一步提高安全性和稳定性,辅助轮系统能够在冲击力过大时增加轮系与地面滚动,提高稳定性,缓冲系统可伸出摩擦块,与地面进行干摩擦,使得飞机速度快速降低。
