Description

technical field

[0001] The invention relates to the technical field of aircraft parking, in particular to a three-redundancy all-electric brake actuation system. Background technique

[0002] The braking system is one of the important subsystems of the aircraft. It is used to complete the safe parking of the aircraft. Its reliability plays an extremely important role in the take-off and landing of the aircraft. The quality of the braking performance directly affects the flight of the aircraft and the crew on board. Safety. The traditional aircraft braking system usually uses a hydraulic device, which requires high sealing of the system, there is a risk of leakage, and the maintainability is poor. The all-electric braking system came into being along with the development of multi- / all-electric aircraft. Compared with the traditional hydraulic brake system, the all-electric brake system has the advantages of small size, light weight, high safety and good dynamic performance....
