A novel integrated self-energy-supply braking system for aircrafts

A novel integrated self-energy-supply braking system (ISBS) is proposed in this paper. The system uses a hydraulic pump to recover the kinetic energy of the aircraft to brake the aircraft, and is designed compact, with all-electrical interface. Therefore the hydraulic piping from the central hydraulic pump is no longer needed while retaining the hydraulic piston as actuators. As a result, the ISBS has higher safety, economy and reliability compared with conventional hydraulic braking system, while having lower heat dissipation and better performance than electric braking system. In addition, the ISBS´s self-energy-supply characteristic makes the aircraft could brake as usual even in lose power emergency case. Simulations were conducted to verify the feasibility of the ISBS by Matlab/Simulink and AMEsim co-simulation method. The results show promising development possibilities for this new system.
