摘　　要：大型客机电传飞控系统采用余度配置是提高飞机安全性与任务可靠性的重要方法之一。大型客机通过余度配置降低系统部件发生故障后对飞行性能和整个系统飞机安全性的影响,从而提高了飞控系统的安全可靠性。本文通过对波音和空客飞机电传飞控系统余度配置等主要设计环节的对比分析,阐述了大型客机电传飞控系统在余度设计与配置方面的关键技术点和方法,为大型客机电传飞控系统的余度设计提供技术支持。Redundant Analysis is a key means of improving the flight control system safety and reliability for the fly-by-wire aircraft. The redundant analysis reduces the influence of the system equipments failures to the flight performance and the system safety. Therefore it can increase the tolerance capacity and system reliability. This article compares the different redundant design between the Boeing and Airbus aircraft applied to the flight control system. The objective of this article is to describe the key points of the aircraft flight control system redundant design and provide the technical support to the advanced fly-by-wire aircraft flight control system design.
