民用飞机结构主要部件失效率研究

飞机结构的安全性和全寿命期内的高可靠性是飞机设计时必须考虑的首要问题。可靠度指标的选取既要考虑技术及经济的可行性，也要兼顾社会的可接受性。基于国外飞机结构的失效率统计数据及主要部件的可靠性系数，经过分析研究给出了国内民用飞机主要部件的失效率。

A Study of Failure Rate for Major Components of Civil Aircraft Structures

The aircraft structural safety and its high reliability in life time must be considered as the primary problem during aircraft design. Not only the feasibility of technology and economy but the social acceptance should be considered upon the choice of reliability index. The failure rates for major components of the civil aircraft structures are given based on the aircraft failure probability statistical conclusion and the reliability factors of the major components.
