The invention relates to the technical field of airplane emergency forced landing, and discloses a ground auxiliary bracket for airplane forced landing. The ground auxiliary bracket comprises a damping wheel; the damping wheel is mounted on a square bearing through a rotating shaft; a damping spring is further arranged at the top of the square bearing, so that when airplane forced landing rear wheels land on the bracket firstly, the rear end of a bottom plate can be effectively damped; buffer springs are further arranged at the bottom of the bracket to damp the whole bracket, and the damping effect is better; a front limiting piece is used for limiting the position of the top end of the airplane; a rear limiting piece can extend out of the bottom plate and is used for limiting the positionof the tail of the airplane; clamping plates can be driven by a first motor to get close to each other to clamp an airplane body of the airplane, is better in fixing effect, and can prevent the airplane from being separated from the bracket; the front limiting piece is used for limiting the position of the airplane and increasing the resistance of the air to enable the bottom plate to stop sliding gradually; and a parachute pack is further arranged at the tail end of the bottom plate, the bottom plate can be further decelerated when the parachute pack is opened, and the deceleration effect isbetter.
本发明涉及飞机紧急迫降技术领域,且公开了一种飞机迫降用地面辅助托架,包括减震轮,减震轮通过转轴安装在方形轴承上,方形轴承的顶部还设置有减震弹簧,当飞机迫降后轮先降落在托架上时,能够有效的对底板的后端进行减震,托架底部还设置有缓冲弹簧,能够对托架整体进行减震,减震效果更好,前限位件用于限制飞机顶端的位置,后限位件可以从底板中伸出,用于限制飞机尾部的位置,夹板在第一电机的带动下能够相互靠拢,夹住飞机的机身,固定效果更好,能够防止飞机脱离托架,前限位件用于限制飞机位置的同时,还可增大空气的阻力,使底板逐渐停止滑行,底板的末端还设置有伞包,伞包打开能够进一步的对底板进行减速,减速效果更好。
