摘要/Abstract

摘要： 对波音和空客系列四种先进机型(B777、B787、A340和A380)的电传容错飞行控制系统进行分析和比较,从软件可靠性和系统重构方面总结出波音和空客系列电传飞控系统的不足和有待改进的地方,并以此出发提出一套符合我国大型民机的余度容错飞控计算机系统新方案。将新方案与波音和空客方案从定性和定量方面进行比较分析,采用分层混合可靠性建模方法对三种方案进行可靠性建模和计算,由结果可得,新方案的可靠性高于波音和空客方案,并以简单的余度结构获得了较高的容错度;从民机的延迟维修和高派遣率要求上,新方案更具优势。

Abstract: The fault-tolerant Fly-By-Wire flight control systems of four advanced aircrafts of Boeing and Airbus series (B777, B787, A340 and A380) were analyzed and compared. The disadvantages needed to be improved were explored in terms of software reliability and system reconfiguration of Boeing and Airbus Fly-By-Wire flight control systems. A novel redundant fault-tolerant flight control computer (FCC) system was presented. The proposed FCC scheme was qualitatively and quantitatively compared with redundant FCC of Boeing and Airbus. The three schemes' reliability was modelled and evaluated through the hierarchical hybrid modelling method. The conclusions are obtained as follows: the proposed FCC of simpler structure has achieved higher reliability and fault tolerance ability; and the advantages of civil aircraft deferred maintenance and high dispatch rate requirements.
