Abstract

The invention provides an aircraft anti-skid brake system fault processing method which is applied to an aircraft anti-skid brake system, and the aircraft anti-skid brake system comprises a brake instruction sensor (1), an anti-skid brake controller (2), a brake cut-off valve (3), an anti-skid brake control valve (4), an aircraft wheel speed sensor (5) and a brake pressure sensor (6). The method comprises the steps that the anti-skid brake system obtains the airplane speed V and the airplane wheel speed V in real time; according to the airplane speed V (km / h) and the airplane wheel speed V (km / h), the airplane wheel slip amount eta of the current airplane wheel is calculated according to a formula, and eta belongs to [0, 1]; the slipping amount eta of the airplane wheel is judged; when eta<M1, it is determined that the airplane wheel is in a normal slipping state; when M1<=eta<M2, it is determined that the airplane wheel is in a moderate slipping state; when eta>=M2, it is determined that the airplane wheel is in a severe slipping state; and a corresponding fault processing strategy is adopted according to the slipping state of the airplane wheel.

Description

technical field

[0001] The invention relates to the technical field of an aircraft anti-skid brake control system, in particular to a method for troubleshooting an aircraft anti-skid brake system. Background technique

[0002] The aircraft braking system is a subsystem with relatively independent functions on the aircraft. Its function is to bear the static weight and dynamic impact load of the aircraft and absorb the kinetic energy of the aircraft when it lands, so as to realize the braking and control of the aircraft's take-off, landing, and taxiing. At present, aircraft braking systems are widely equipped with anti-skid control functions to ensure that the aircraft will not brake tires during the braking process, prevent aircraft brakes from blowing out, and improve the safety of aircraft braking and deceleration.

[0003] However, there is a common deficiency in aircraft at present. The anti-skid braking system of the aircraft is controlled by electro-hydraulic pressure....
