Abstract

The invention provides a self-energy feedback type brake apparatus-based airplane braking system and a control method of the self-energy feedback type brake apparatus-based airplane braking system. The method comprises the following steps: an airborne power source provides electric energy to each self-energy feedback type brake apparatus; an airplane braking system controller controls each self-energy feedback type brake apparatus and braking actuators which are connected with the corresponding self-energy feedback type brake apparatuses to provide braking power when receiving an airplane braking instruction. The system and the control method have the advantages that the braking system has an integrated structure, and the amount of parts can be reduced due to the high integration of the modules, thus the braking system is extremely high in reliability and maintainability; the braking system is independent of host computer energy sources, and the braking can be completed even when the host computer is under the normal state or the power-free emergency state; the braking system is encapsulated into an electro-hydraulic integrated device interface, a hydraulic pipeline of a pump resource in a resource self-cluster is cancelled, and the weight of the airplane is reduced, so that the safety of the airplane can be improved.

Description

technical field [0001] The invention relates to the field of aircraft braking systems, in particular to an aircraft braking system based on a self-feeding braking device and a control method thereof. Background technique [0002] The aircraft braking system is an important part of modern aircraft, mainly used to dissipate the kinetic energy of the aircraft when it is sliding on the ground, to ensure that the aircraft brakes to stop, to shorten the distance of the aircraft to run, to prevent excessive wear of the wheels, and to cooperate with other airborne The system realizes the turning and parking functions of the aircraft, and is an important system to ensure the safe take-off and landing of the aircraft. Therefore, whether the aircraft braking system can operate normally and reliably is very important. [0003] Whether the aircraft brake system is safe and reliable is directly related to the safety and reliability of the aircraft as a whole. Because the hydraulic brake ...
