摘要
从运输类飞机适航规章的“失效-安全”要求出发,通过总结当前波音和空客主流机型终极备份的应用情况,对比分析了终极备份方法的应用形式、功能和目的。同时通过仿真某机型在不同终极备份方法下飞机的稳定性和操纵性,得到结论如下:运输类飞机都应配备终极备份;终极备份至少两轴可控,俯仰+滚转或俯仰+偏航;两轴的终极备份方式可以实现飞机的稳定可操纵,但达不到继续安全飞行和着陆的能力。终极备份的目的和系统设计方案取决于飞机本身特征,需要在飞机顶层设计时综合考量。
Based on the "fail-safe" demands of airworthiness regulations for transport aircraft,this paper summarizes the current application of ultimate backup of Boeing and Airbus aircrafts,and compares and analyzes the application form,function and purpose of the ultimate backup method.Through simulating the stability and maneuverability of a certain aircraft using different ultimate backup methods,the conclusions are as follows.Transportation aircraft should be equipped with ultimate backup.The ultimate backup has at least two controllable axes,pitch+roll or pitch+yaw.The ultimate two-axis backup allows the aircraft to be stable and maneuverable,but not to continue to fly and land safely.The purpose of ultimate backup and system design depends on the characteristics of the aircraft,which need to be considered in the top-level design of the aircraft.
