Problems solved by technology

In this setting, once the wheel load signal fails, the aircraft is in the ground state after touching the ground, and the wheel load signal indicates that it is in the air state. At this time, the brake grounding protection is effective. The driver steps on the brake and the system does not brake due to the ground protection. The pressure will cause the system to fail to brake and run off the runway, seriously affecting the safety of the aircraft

Embodiment Construction

[0009] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0010] Such as figure 1 Shown, a kind of aircraft brake grounding protection system comprises brake controller 1, left brake control valve 21, right brake control valve 22, left wheel speed sensor 31, right wheel speed sensor 32, left wheel load sensor 41 and right wheel load sensor 42, wherein the oil inlet of the left brake control valve 21 and the oil inlet of the right brake control valve 22 are connected to the hydraulic source, the working port of the left brake control valve 21 is connected with the left wheel brake device, and the left wheel speed sensor 31 Installed on the left wheel brake device, the left wheel load sensor 41 is also installed on the left wheel brake device; the working port of the right brake control valve 22 is connected with the right wheel brake device, and the right wheel speed sensor 32 is installed on the right wheel brake device. O...

Abstract

The invention relates to an aircraft brake ground protection system which comprises a brake controller, brake control valves, aircraft wheel speed sensors and wheel load sensors, wherein the aircraft wheel speed sensors and the wheel load sensors are used for judging whether an aircraft is in an aerial state or a ground state. If the judging result shows that the aircraft is in the ground state, a pilot applies left and right brake instructions, the brake controller applies brake control signals to the brake control valves according to the brake instructions, and the brake control valves output brake pressure to enable the aircraft to be in a brake state; and if the judging result shows that the aircraft is in the aerial state, even if the pilot applies the left and right brake instructions, the brake controller can not apply the brake control signals to the brake control valves, and the aircraft is in a brake loosened state, thereby preventing the aircraft from landing in a braked mode because the pilot puts on the brakes by mistake in the landing process of the aircraft so as to prevent the tire skidding of the aircraft.

Description

technical field [0001] The invention relates to the technical field of aircraft brake systems, in particular to an aircraft brake grounding 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, the aircraft brake ground protection system usually uses the wheel load signal as the aircraft air-ground status judgment. When the wheel load is in the air state, the brake The grounding protection is valid, and when the wheel load is on the ground, the brake grounding protection is released. In this setting, once the wheel load signal fails, the aircraft is in the ground state after touching the ground, and the wheel load signal indicates that it is in the air state. At this time, the brake ground protection is effective, and the driver steps on the brake, but the system does not brake due to the ground protection The...
