Aircraft brake dynamic-state and static-state comprehensive control system and aircraft brake dynamic-state and static-state comprehensive control method

Abstract

The invention relates to an aircraft brake dynamic-state and static-state comprehensive control system, which comprises a brake command sensor, a brake controller, a brake control valve, a wheel brake device and a wheel speed sensor. According to the aircraft brake dynamic-state and static-state comprehensive control method, the condition that an aircraft is in a dynamic state or static state is determined through the wheel speed sensor signal to achieve different brake control laws, wherein the brake command is in the maximum value during the static-state braking and the corresponding brake system output pressure is the static brake pressure, and the brake command is in the maximum value during the dynamic-state braking and the corresponding brake system output pressure is the maximum normal brake pressure. According to the present invention, it can be ensured that the aircraft can automatically switch to the normal brake state and the static brake state during the take off process according to the aircraft state, it can be ensured that the pilot uses the pedal to perform the brake, the normal braking and the static braking can be achieved, the equipment additionally added to the configuration is not required, the burden on the pilot control is reduced, and the use reliability of the aircraft is improved.

Description

technical field [0001] The invention relates to the technical field of aircraft brakes, in particular to an aircraft brake dynamic and static comprehensive control system. Background technique [0002] As an important airborne equipment, the aircraft brake control system, whether the brake system can work normally will seriously affect the safety of the aircraft. At present, the aircraft brake control system, most aircraft brake discs use carbon brake discs, and are equipped with static brake systems, carbon brakes One of the biggest characteristics of the disc is that the dynamic and static friction coefficients are inconsistent. The static friction system is much smaller than the dynamic friction coefficient. Therefore, it is necessary to ensure that when the aircraft is in a high-thrust state at the take-off line, the braking system can stop the aircraft wheels and the static braking of the aircraft The pressure must be considerably higher than the maximum normal brake pr...

Problems solved by technology

The biggest disadvantage of the above two configurations is that there are many system accessories, which reduces the reliability of the aircraft and the system. At the same time, after the static brake switch is set, the driver's control burden is increased.
