Aircraft double-redundancy anti-skid control system

Abstract

The present invention relates to an aircraft double-redundancy anti-skid control system, which comprises an anti-skid controller, an electromagnetic hydraulic lock, a brake control valve and a wheel speed sensor. According to the present invention, during a normal anti-skid control process, the main anti-skid control plate card of the anti-skid controller, the brake control valve, and the main electrical coil of the wheel speed sensor are in a working state, the standby anti-skid control plate card and the standby electrical coil are in a warm standby state, the anti-skid control system automatically switches to a standby working state when any one of the main anti-skid control plate card, the brake control valve and the main electrical coil of the wheel speed sensor produces failure, and no influence is generated to the main anti-skid control when any one of the standby anti-skid control plate card of the anti-skid controller, the brake control valve and the standby electrical coil of the wheel speed sensor produces failure, such that the operation reliability of the anti-skid control system is improved, and the aircraft safety is effectively improved.

Description

technical field [0001] The invention relates to the technical field of aircraft anti-skid brakes, in particular to an aircraft dual-redundancy anti-skid control system. Background technique [0002] Aircraft anti-skid brake control system is an important airborne equipment. Whether the anti-skid system can work normally will seriously affect the safety of the aircraft. At present, most of the aircraft anti-skid control systems use a single set of anti-skid control system, and one wheel is installed on the left and right main wheels. The speed sensor calculates the sliding state of the main engine wheel of the aircraft according to the signal of the wheel speed sensor. Once it is judged that the main engine wheel is in the brake locked state, the anti-skid system releases the brake pressure to make the wheel rotate again, but such anti-skid control is in the setting Without considering the margin, once any wheel speed sensor, or anti-skid control channel, or anti-skid control...

The speed sensor calculates the sliding state of the main engine wheel of the aircraft according to the signal of the wheel speed sensor. Once it is judged that the main engine wheel is in the brake locked state, the anti-skid system releases the brake pressure to make the wheel rotate again, but such anti-skid control is in the setting Without considering the margin, once any wheel speed sensor, or anti-skid control channel, or anti-skid control board fails, the anti-skid system will be released, and the system does not have anti-skid control during the braking process. When the driver brakes too hard, it is easy to Brake blowout occurs, or the aircraft cannot be controlled on a slippery runway, which will seriously affect the safety of the aircraft
