According to the airplane braking system and the emergency braking and shutdown braking control method, additional braking redundancy is provided for the airplane braking system, the usability of the braking system is improved, whether shutdown braking is carried out or not is judged through a shutdown switch and the state of an airplane, the safety of shutdown braking of the airplane is improved by 12%, and the structural weight of the system is reduced by 4.5 kg. And the brake controller implements emergency brake by judging the states of the stop valve and the servo valve, so that the redundancy of the brake system is increased, and the usability of the brake system is improved by 30%. Meanwhile, under the condition that a brake system is powered off, a shutdown brake relieving function is provided, under the condition that skid resistance fails, the purposes of improving the brake safety of the aircraft and reducing the tire burst probability of the aircraft are achieved, and the workload of a pilot is relieved; when the airplane is in a non-static state, the brake controller provides extra redundancy for the brake system, and the usability of the brake system is improved; override is conducted on stopping brake through pedal brake, pedal brake pressure is output, and it is guaranteed that the airplane can stop.
一种飞机刹车系统及应急刹车与停机刹车的控制方法,为飞机刹车系统提供了额外的刹车余度,提高了刹车系统的可用性,通过停机开关及飞机的状态判断是否实施停机刹车,使飞机停机刹车的安全性提高了12%,减轻了系统的结构重量4.5kg。刹车控制器通过判断切断阀和伺服阀的状态实施应急刹车,增加了刹车系统的余度,刹车系统的可用性提升了30%。同时,在刹车系统断电情况下提供了解除停机刹车功能,在防滑失效情况下飞机刹车的安全性,降低飞机爆胎概率的目的,减轻了飞行员的工作负担;当飞机处于非静止状态时,刹车控制器为刹车系统提供了额外的余度,提高了刹车系统的可用性;通过脚蹬刹车对停机刹车进行超控,输出脚蹬刹车压力,保障飞机能够停止。
