Design and modeling of a novel self-powered brake system for MEA

Traditional hydraulic braking system requires lengthy and complicated pipelines, from aircraft engine driven pump (EDP) to braking actuators, which may cause serious pipeline vibration and leakage problems. This research proposes a novel integrated self-powered braking system (ISBS) for aircrafts. The new system demands no external hydraulic source, and no complicated pipelines. It can recover the kinetic energy of the landing aircraft through a hydraulic pump geared by main wheel, and serves as hydraulic power supply for the brake actuators. The new system is expected to be more economical, reliable and safer. Another notable advantage is the failure-proof braking function under conditions of emergency such as power interruption. In this paper, the working principle of the ISBS is explained. As a conclusion, this self-powered aircraft braking system provides a new solution with a great potential in the field of more-electric aircraft.
