Title

A Novel Aircraft Brake System and Adaptive Anti-skid Control Method

Abstract

 

Traditional hydraulic brake systems require complex system of pipelines between the aircraft Engine Driven Pump and the brake actuators, which increases the weight of the aircraft and may even cause serious vibration and leakage problem. In order to improve the reliability and safety of the aircraft, we propose a new Integrated Self-energized Brake System for aircrafts. It uses a hydraulic pump geared to the main wheel to recover a small part of the kinetic energy of the landing aircraft. The recovered energy then serves as the hydraulic power supplying for the brake actuators. It does not require additional hydraulic source, thus simplifying the pipelines system. The ISBS presents a good performance and provides a new solution in the field of the More Electric Aircraft brake system. In which On-Off switch valves are used to get more efficient control. Furthermore a new Anti-skid method is put forward, it can adapt the difference road surface and loads, to keep the maximum brake efficient.
