Embodiment Construction

[0030] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0031] The operating mode of the aircraft braking device shown in this embodiment is an aircraft braking system with hand brake and foot differential. like figure 1 As shown, the aircraft brake device includes a hydraulic brake valve 1 and a brake distribution valve 2, the hydraulic brake valve 1 is used to start the brake, sends a brake command to the wheel brake device and provides brake pressure, and the brake distribution valve 2 is used to control the braking after the brake is activated. Aircraft directional brake correction and aircraft taxiing ground turn. The oil i...

Abstract

The invention belongs to the technical field of airplane wheel braking, and particularly relates to a control device for airplane braking. Speed sensors are added to collect airplane speed signals, pressure sensors are added to collect left and right wheel instruction braking pressure, the airplane speed and the instruction braking pressure difference are taken as decision parameters for quittingantiskid control, and an antiskid braking control box quits antiskid control as long as the airplane speed during braking and turning is in an antiskid failure speed, or as long as the left and rightinstruction braking pressure difference is larger than a preset value, the antiskid braking control box also quits from antiskid control, so that ground brake turning and low-speed sliding brake are prevented from being interfered by antiskid control induced by false signals.

Description

technical field [0001] The invention belongs to the technical field of aircraft wheel brakes, in particular to a control device for aircraft brakes. Background technique [0002] Differential braking is a control mode used to correct the direction of aircraft roll and turn the aircraft on the ground. In the process of entering and exiting the runway, it is an indispensable action for the pilot to control the aircraft to turn on the ground. For aircraft that do not have a specially designed nose wheel steering control mechanism, the ground taxiing turn is mainly realized by the differential braking of the left and right landing gear wheels by the aircraft braking system. Even with the nosewheel steering mechanism, differential braking is an effective method for directional control of the aircraft roll. The direction of braking and turning depends on the values ​​of the braking torque of the wheels on both sides. Which side of the braking torque is greater, the nose of the a...
