Abstract

The invention discloses an antiskid braking control system for an airplane. A left braking instruction sensor, a right braking instruction sensor, a left wheel speed sensor, a right wheel speed sensor, a cabin operation information port and a charcoal / charcoal (C / C) information storage unit are connected with an antiskid braking controller; and the antiskid braking controller controls a left mainmachine wheel and a right main machine wheel through a left electrohydraulic pressure servo valve and a right electrohydraulic pressure servo valve respectively. The antiskid braking control system for the airplane can effectively prevent the moment of a charcoal tray from reaching the peak, automatically regulates braking pressure, and powerfully ensures that the braking process is stable and safe.

Description

technical field [0001] The invention belongs to the field of aircraft anti-skid brake control and relates to an aircraft anti-skid brake control system. Background technique [0002] At present, carbon / carbon (C / C) composite materials have the characteristics of light material and high density, and have been widely used in aircraft braking systems. Since the dynamic friction torque of C / C friction materials has the characteristics of changing with different speeds, these characteristics determine The reason is that when the aircraft starts to brake during the landing process, the torque peak appears more obvious, resulting in overshooting of the slip rate, frequent anti-skid, brake vibration, and poor stability of the aircraft's braking. [0003] The current workaround is: [0004] 1. Change the technological level of C / C materials, improve the performance of C / C materials, and develop materials with high performance and low peak-to-valley ratio. However, due to the comple...
