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.
The vulnerability of an aircraft to a single threat of attack is usually given in terms of probability of killing or vulnerable area. This method of assessment usually evaluates the vulnerability of aircraft and its components at a macroscopic level. However, a specific one Vulnerability of aircraft position is hard to be intuitively presented. A method of killing probability mapping analysis for aircraft vulnerability assessment is presented. The method uses the finite element model of aircraft and components as input data, Combustion, Detonation, Penetration and their combinations of killing mode, by calculating each firing line hit each position under the killing probability value of the aircraft, and finally can provide aircraft probability of killing the cloud application shows that: Killing probability map analysis can be intuitively displayed The regional distribution of aircraft kill probability can be used as a useful supplement to evaluate the vulnerable area, which is instructive for the reduction / reduction design of survivability.
