摘要
提出了一种飞机结构缺陷漏检概率评估与控制技术 ,利用该技术可以有效地提高单机乃至机群中缺陷 (裂纹 )检出概率 ( POD) ,并可以对缺陷 (裂纹 )的漏检概率进行准确地评估和控制 ,使飞机因裂纹漏检而造成事故的可能性降至最低程度 ,从而确保飞机的安全飞行。
A method for evaluating and controlling the probability of missed flaws in aircraft structure is presented in this paper. The method can control the largest size of the flaws missed at nondestructive testing with high probability of flaw detection and confidence level.This method can also raise the flaw detection probability and avoid flight accidents caused by the missed flaws in aircraft structure.It is simple and convenient for application in engineering.
