Problems solved by technology

At present, most aircraft use carbon brake materials. One of the biggest characteristics of carbon brake materials is that the coefficient of static friction is much smaller than the coefficient of dynamic friction. For military and civilian aircraft, in order to reduce the take-off run distance, engine afterburning is usually used for take-off, which is The aircraft is required to brake the wheels before take-off, so a large static braking pressure is required, which is much higher t

Abstract

The invention relates to an aircraft static brake and a protection system thereof. The system includes a brake controller, a static brake switch, a static brake electromagnetic valve, conversion valves and wheel speed sensors. The aircraft static brake provided by the invention adopts a static brake switch to control the on-off of a static brake system, when the brake control unit detects that the aircraft meets the static brake system on-condition, the static brake switch is flipped to an on-position, the static brake electromagnetic valve can be connected, static brake oil fluid reaches brake wheels through the static brake electromagnetic valve and the conversion valves, when the brake control unit detects that the aircraft does not meet the static brake condition, the static brake switch is flipped to the on-position, the static brake switch cannot be pulled in to the on-position, and the static brake electromagnetic valve is not connected and therefore does not work at the moment. According to the invention, misoperation of the static brake system is effectively prevented, and the use safety of aircrafts is improved.

Description

technical field [0001] The invention relates to the technical field of aircraft brake systems, in particular to an aircraft static brake and its protection system. Background technique [0002] The aircraft brake control system is an important airborne device, whether the brake system can work normally will seriously affect the safety of the aircraft. At present, most aircraft use carbon brake materials. One of the biggest characteristics of carbon brake materials is that the coefficient of static friction is much smaller than the coefficient of dynamic friction. For military and civilian aircraft, in order to reduce the take-off run distance, engine afterburning is usually used for take-off, which is The aircraft is required to brake the wheels before take-off, so a large static braking pressure is required, which is much higher than the normal braking pressure of the aircraft, so the aircraft is equipped with a static braking system, usually with a simple switch in the coc...
