Inertial anti-skid braking system and control condition determination method

Abstract

The invention provides an inertial anti-skid braking system and a control condition determination method. The inertial anti-skid braking system provided by the invention adopts the structure that a floor switch is added to an inertial anti-skid braking system in the prior art, the positive pole of an electric apparatus contact of the floor switch is connected with the positive pole of an electric apparatus contact of an inertial sensor, and the negative pole of the electric apparatus contact of the floor switch is connected with the negative pole of the electric apparatus contact of the inertial sensor. The floor switch on an airplane undercarriage is logically synthesized with accessories of the braking system, and the braking pressure is locked in the air, so that before touch-down of an airplane or when the braking airplane wheel does not rotate fully although the airplane touches down, the inertial anti-skid braking system cannot apply braking pressure to the braking airplane wheel; and after ground protection fails, the anti-skid braking system conducts normal braking on the braking airplane wheel.

Description

technical field [0001] The invention relates to the field of aircraft braking systems, in particular to an inertial anti-skid braking system with a grounding protection function and a method for determining control parameters. Background technique [0002] The inertial anti-skid braking system of domestic second-generation and third-generation aircraft in active service has no grounding protection function. In order to ensure the safety of aircraft landing, the flight manuals of the second-generation and third-generation aircraft in active service require: "Pilots are strictly prohibited from stepping on the brake pedal in the air." Ensure safe landing of aircraft by restricting pilot operations. However, the pedals have other control functions, which often cause the pilot to accidentally step on the brakes in the air, causing the aircraft to land under pressure. [0003] The structure diagram of the inertial anti-skid braking system without ground protection function is s...

Problems solved by technology

"Aircraft Braking System Design" published by Northwestern Polytechnical University listed the inertial anti-skid braking systems of "Su-27" and "Il-76" in the description of typical inertial anti-skid braking systems. The inertial anti-skid braking system is improved on the anti-skid control rate of the original inertial anti-skid braking system. It adopts dual-signal working mode, automatic tire dragging device, hydraulic limiter and other improvement measures. The system is safe, the braking is stable, and the braking efficiency is high. -27" and "Il-76" aircraft have no grounding protection function for the inertial anti-skid braking system
