Embodiment Construction

[0026] The front landing gear wheels of modern aircraft generally do not have brakes, and brake devices are equipped on the wheels of the two main landing gears. The two aircraft main landing gears are usually arranged symmetrically on both sides of the aircraft fuselage. In this embodiment, one of the main landing gear and one wheel is installed as an example to illustrate the fly-by-wire hydraulic braking system of an aircraft with automatic braking capability according to the present invention.

[0027] In this embodiment, the automatic brake is set to one level; the automatic brake anti-skid valve adopts an independent anti-skid valve, and the electro-hydraulic servo valve is used as the anti-skid valve; the pressure supply of the automatic brake is separately provided by the decompression valve.

[0028] This embodiment is an aircraft braking system with automatic braking, including: a braking command sensor 1 , a control box 4 , a first electro-hydraulic servo valve 3 , ...

Abstract

The invention discloses an airplane electric transmission brake system capable of automatic braking and a braking method. An automatic braking switch is installed inside a driving cabin; the automaticbraking switch is electrically connected with an electro-hydraulic valve through a cable; the automatic braking switch is controlled by a driver manually and controlled for providing or disconnectinga power supply for the electro-hydraulic valve so as to control the electro-hydraulic valve to be connected or disconnected. The automatic braking system is constructed by using existing mature accessory parts, so that an airplane normal braking system has an automatic braking capacity, the operation selection range of the normal braking system are completed and enlarged, and the available combined torque of a pavement is sufficiently utilized to the maximum extent, so that the landing skating distance is shortened by about 35% by compared with conventional braking when the automatic brakingmanner is used, the taking-off and landing safety of an airplane is guaranteed, the airport pavement utilization rate and equipment utilization rate are improved, and the economic, social and militarybenefits are obvious.

Description

technical field [0001] The invention relates to an aircraft wheel fly-by-wire braking system, in particular to an aircraft fly-by-wire braking system and method capable of automatic braking. Background technique [0002] The aircraft wheel brake system is a component of modern aircraft landing gear, and is the basic guarantee equipment for the safe operation of aircraft take-off, landing roll and ground taxi control. Prevent punctured tires. Experimental research and use have shown that under certain conditions, the use of automatic braking can effectively shorten the landing roll distance of the aircraft. Automatic braking has also been long-awaited to relieve the driver of the load during safety-critical landings. At present, general aircraft do not have the ability to automatically brake, including aircraft that use fly-by-wire brakes. When braking, the driver needs to step on the brake pedal or manipulate the brake valve or brake command sensor. Only Boeing, Airbus and...
