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

Abstract

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.
