摘　　要：飞机在威胁单次打击下的易损性通常是以杀伤概率或易损面积形式给出的,这种评估方法往往是在宏观上对飞机及其部件易损性进行评估,然而具体的某一飞机位置的易损性很难直观给出.提出了一种飞机单击中易损性评估的杀伤概率图谱分析法.该方法以飞机及部件的有限元模型作为输入数据,考虑了部件的引燃、引爆、穿透及其组合杀伤模式,通过计算每一条射击线打击下飞机各个位置的杀伤概率值,最后可以提供飞机的杀伤概率云图.应用中表明:杀伤概率图谱分析法可以直观的显示飞机杀伤概率的区域分布,可以作为易损面积评估的有益补充,对于生存力增强/易损性减缩设计具有指导意义.Aircraft single threat hit vulnerability is usually expressed as the kill probability or vulnerable area. This method seems to evaluate the aircraft or component vulnerability from the general point of view. However, the specifie location vulnerability of an aircraft cannot be intuitively assessed. This paper provides a method for drawing the kill probability contour for evaluating the single hit vulnerability. In this method, the aircraft finite element model is used as the input, then the kill probability of hit of a certain position by a shot line is calculated in which component kill modes such as penetration, combustion, burst and combination of them are considered, and the aircraft kill probability contour can be finally obtained. Analysis shows that, the kill probability contour may provide the distribution of aircraft kill probability, and may be regarded as the supplementary to the vulnerable area method. This method is useful to provide valuable advice on aircraft survivability enhancement or vulnerability reduction design
