Problems solved by technology

However, this patent does not solve the problem that the braking pressure of the take-off line changes from static braking pressure to normal braking pressure. During the process of pressure change, the static braking torque of the brake main engine wheel jumps down in a "cliff-like" manner.

Abstract

A static brake pressure linear control method of a digital telex anti-skid brake system is disclosed. Through an anti-skid brake control box, the states of a brake command sensor and a static brake switch can be monitored in real time; through the states of the brake command sensor and the static brake switch, the states of an electric hydraulic pressure servo valve and an electromagnetic hydraulic lock can be determined; by adopting such control logic, the voltage-current gain of the electric hydraulic pressure servo valve controlled by an anti-skid brake control box 4 is realized; and the static brake pressure linear control is achieved. A dual wheel plane digital telex anti-skid brake system is taken as the base, the present structure, mechanical interfaces and electrical interfaces ofthe digital telex anti-skid brake system are maintained, by changing the static brake control logic, the linear control of plane static brake pressure and brake force moment is realized, the safe take-off is guaranteed, and the man-machine interaction of the brake system is excellent.

Description

technical field [0001] The invention relates to an aircraft digital fly-by-wire anti-skid braking system with a static braking control function. Specifically, the braking command voltage signal and the static braking switch state signal are detected in real time by the braking system to jointly control the static braking pressure output by the static braking system. Make the digital fly-by-wire anti-skid braking system meet the technical requirements of the aircraft static braking system and the ergonomics requirements. Background technique [0002] The take-off weight and engine thrust of modern aircraft are increasing. In order to shorten the take-off distance of the aircraft, the static braking pressure required for the aircraft to take off is increasing. As a result, the static braking pressure of the aircraft is much greater than the braking pressure during the normal landing of the aircraft. [0003] The static braking function of the aircraft is realized by the normal...
