The invention provides a brake control method for an airplane anti-skid fault, and belongs to the technical field of airplane wheel braking. The method comprises the steps that a brake controller judges whether a takeoff stopping brake exists or not; judging whether the skid resistance fails or not; according to the type of the runway and the result of whether takeoff is stopped or not, the deceleration of the main wheel is compared with the maximum deceleration of takeoff stopping braking or the maximum deceleration of non-takeoff stopping braking, and whether the main wheel enters a deep slip state or not is judged; according to the runway type and the take-off brake state, brake pressure output after anti-skid failure is determined, and high-speed brake operation is executed; judging whether to quit the anti-slip function; and the brake pressure after the anti-skid function is quitted is determined, and low-speed brake operation is executed. The maximum deceleration of the stop take-off brake is introduced into the anti-skid function, and the wheel deceleration is compared with the maximum deceleration of different modes, so that the wheel is prevented from entering deep skid and even being locked, and the safety of the aircraft brake is improved.

    本发明提供一种飞机防滑故障的刹车控制方法,属于飞机机轮刹车技术领域,该方法包括:刹车控制器判断是否是中止起飞刹车;判断防滑是否失效;根据跑道类型和是否是中止起飞刹车的结果,将主机轮减速度与中止起飞刹车最大减速度或非中止起飞刹车最大减速度进行对比,判断主机轮是否进入深打滑状态;根据跑道类型和起飞刹车状态,确定防滑失效后输出的刹车压力并执行高速刹车操作;判断是否退出防滑功能;确定退出防滑功能后的刹车压力并执行低速刹车操作。在防滑功能中引入中止起飞刹车最大减速度,通过机轮减速度和不同模式的最大减速度对比,防止机轮进入深打滑甚至抱死,提高了飞机刹车的安全性。
