飞机结构寿命包线的确定方法

Determination of Aircraft Structural Life Envelope

在飞机结构寿命包线概念基础上,阐述了基准使用条件下由实验确定飞机结构寿命包线的基本方法及工程简化方法,进一步说明了在非基准使用条件下实验确定飞机结构寿命包线的基本方法及工程简化方法,为实现飞机结构单机寿命(疲劳寿命和日历寿命)监控奠定了基础。

Based on the introduction of the concept of aircraft structural life envelope （ASLE） , the basic approach and practical engineering method of determining ASLE by experiments under the baseline operational conditions are presented, as well as the basic approach and practical engineering method of determining ASLE by experiments under non - baseline operational conditions. The determination of ASLE will pave the way for Service Life （ i. e. fatigue life and calendar life ） Supervision for Individual Aircraft Structural System.
