摘要
在分析现有飞机结构寿命指标及其确定方法的基础上,提出了飞机结构寿命包线的概念,给出了建立飞机结构寿命包线的方法,并绘制出了基于飞机结构总寿命以及首翻期/翻修间隔期的飞机结构寿命包线示意图。飞机结构寿命包线的建立将为进一步对飞机结构进行单机寿命(疲劳寿命与日历寿命)监控奠定基础。
Based on the analysis of present aircraft structural life index and its determination, the concept of Aircraft Structural Life Envelope (ASLE) is presented, as well as the approach to the establishment of ASLE. The schematic diagram of ASLE is given based on the total life and the time interval between overhauls. The establishment of ASLE will pave the way for the structural life ( i.e. fatigue life and calendar life ) supervision for individual aircraft.
