为了确保飞行控制系统的任务可靠性和安全可靠性，国外先进民机飞行控制计算机均采用余度技术。非相似余度技术采用完全不同的硬件和软件组成余度通道，产生和监控飞行控制信号，可避免多通道余度系统共性故障的产生，达到较高的可靠性。文中针对非相似余度设计技术，深入研究波音和空客飞机飞控计算机的余度技术，分析其飞控系统的可靠性，再根据我国的技术实力和研发能力，提出了我国民机飞控计算机余度设计的一种方案，并且用可靠性理论进行了验证。

To insure task reliability and safety reliability of flight control system,non-similar redundancy technique has been adopted by foreign advanced airplane's flight control computer. Non-similar redundancy technology uses different hardware and software to build re-dundancy channel,which generates and controls flight control signal. It can match high reliability because of avoiding the correlated faults. It lucubrates redundancy technique of flight control computer of Boeing and Airbus,analyzes the reliability of them. Then,raise an project of redundancy technique of flight control computer according to domestic technical strength and developing ability,and validate the project using reliability theories.
