电传操纵系统在民用客机中的新发展

New Development in the Fly-by-wire System of Civil Airliners

30年来，随着自动控制理论和计算机技术的飞速发展，使飞行器自动控制系统日臻完善，为更好地完成复杂的飞行任务提供了可靠保证。飞机的操纵系统也发生了巨大变化，操纵杆系和钢索已被电线所取代，计算机和反馈信号在飞行操纵系统中的引入，使飞机的操纵性能产生了质的飞跃。介绍了目前中国民航所使用的新型客机中电传操纵系统的一些新发展。

With the rapid deveoprnent in the theory of automatic control and computerized technology,the automatic control system of aircraft is being perfected, thus ensuring better carrying out complicated flights. Great changes have also taken place in the control spstem of aircraft. Control sticks and cables have been replaed by wires. With the introduction of computer technology and the signals into the control system of aircraft, the control performance of aircraft has taken a substantial leap forward. This paper gives a brief introduction to the new deveopnd in the fly-by-the systerm of the modern airliners in China's civil aviation industry nowadays.
