How the variation of take-off suspension weights affects the structural fatigue life is investigated through surveying actual flight parameter recorder (FPR) data.
主要通过飞行参数记录仪(FPR)记录的数据研究战斗机起飞外挂重量对飞机结构疲劳寿命的影响。
For the fighter involved in the investigation, scatter in fatigue damage caused by take-off suspension weights during one flight can reach 27% of the design criteria.
对某型飞机的一次完整飞行，按不同起飞外挂情况计算其损伤比值，结果表明分散度达到设计基准的27%。
The investigation shows that actual take-off suspension weights chang considerably and irregularly, so it is important to calculate fatigue damage based on actual suspension weights for each flight.
通过调查飞机挂弹架次比例，发现情况变化随意性很强，基本无统计规律可循，因而按每架次实际起飞外挂重量计算疲劳损伤显得尤为必要。
