基于飞控系统故障后的飞行品质评定方法适航验证技术研究

Research on Airworthiness Certification Technology Based on Handling Qualities Rating Method after Flight Control System Failure

使用电子飞行控制系统的运输类飞机必须要满足适航安全性的要求。由于运输类飞机通用的规章(14CFAR25部)中许多稳定性和操纵性的要求已经不能代表和覆盖对这类飞机的最低安全要求,因此需要采用新的适航验证方法进行适航评定。通过对某型飞机的研究,采用HQRM方法评定,给出了分析取证的流程以及思路,最后给出按照不同组合概率选取不同的适航验证方案。

The transport category airplanes employing electronic flight control systems （EFCS） must meet the re- quirements of safety. As the stability and control requirements in the regulations for transport aircraft （ 14 CFAR 25 ） hasn＇ t been able to stand for and cover with the lest safe requirements for such aircraft , a new method of air- worthiness certification need to be used for airworthiness assessment. This paper provides some produces and ideas for compliance through studying a certain airplane with Handling Qualities Rating Method （HQRM）.
