Abstract

An airplane inertia anti-skid brake system capable of guaranteeing emergency brake comprises a normal brake system and an emergency brake system, wherein the normal brake system and the emergency brake system adopt two independent pressure supply source systems and are switched through a switching valve. The system structure is improved through addition of a control device, so that normal brake fails during emergency brake, the switching valve is completely switched under the action of emergency brake pressure, and even though the emergency brake and the normal brake are used simultaneously, the switching valve can be switched to the emergency brake system. The control device adopts an electrical switch, a circuit of a solenoid valve is off by the switch, if the normal brake is used, the solenoid valve releases pressure of the normal brake system, the switching valve is thoroughly switched without hindrance, and emergency brake pressure is output.

Description

technical field

[0001] The invention relates to an aircraft wheel braking system, in particular to an improved aircraft inertial anti-skid braking system, which ensures that the emergency braking operation is not affected by normal braking. Background technique

[0002] The aircraft wheel braking system is an important part of the landing gear of the aircraft, which is used to shorten the run distance after the aircraft lands normally, stop the aircraft as soon as possible, and prevent the tires from bursting. The aircraft inertial anti-skid braking system was applied earlier, and it is still used in some aircrafts. The braking system includes two parts: normal braking and emergency braking. The emergency braking system is used after the normal braking system fails or in certain situations. A switching valve is arranged between the normal braking system and the emergency braking system, and the switching valve is used to switch from the normal braking system to the emergenc...
