Abstract

Reliability is one of the most important target in airplane designing, the redundancy technology is universally used in servo-actuator system of civil aircraft´s Fly-by-Wire System (FBWS). In order to attain a high reliability, firstly the system structure is designed and redundancy allocation is given, accordingly the redundant management strategy and realization are described in detail. Based on Markov process reliability model is established. Taking fault coverage percentage of the first time and the second into account, reliability of the system is analyzed. The simulation result shows that the system has a high reliability.
