军用飞机易损性关键部件关键度研究

关键部件的分析是易损性数值量度的基础。使用"关键度"的概念,可以用来定量描述部件对军用飞机总体易损性的重要程度。根据部件被杀伤的指标特征可以构造部件的三个杀伤指标,并由此对燃油系统易损性关键部件的关键度进行定量计算,从而可以直观地得出燃油系统各个子系统对整体易损性的重要程度。这种方法不仅能够为军用飞机易损性评价提供原始数据,也可以辅助军用飞机易损性减缩设计并预测易损性减缩效果。

Research on the critical degree of vulnerability critical components of military aircraft

The identification of the critical components is the important part of the vulnerability assessment.In this paper,we propose the concept of "Critical Degree" to describe the component's impact on the entire military aircraft vulnerability.Based on the analyzing of components kill characters,we defined three kinds of kill indexes: kill severity,kill probability and kill relevancy.the critical components Identification may be achieved through these indexes.It is a new and developing method for quantifying the critical degree of critical components,and we hope it should offer useful original data in vulnerability assessment and should play a important part in aircraft vulnerability reduction design.
