摘　　要：介绍飞机易损性评估的基本方法,设计并开发一种通用的易损性评估软件系统。该软件共划分为5大基本模块:数据输入模块、图形显示模块、威胁输入模块、计算方法及系统设置模块和结果显示模块。该系统可以提供飞机及部件在非爆穿透物任意攻击方向上的单次及多次打击的毁伤概率及易损面积、导弹破片威胁下的飞机易损性、飞机典型爆炸平面上冲击波易损性包线的绘制结果。与国内外类似软件相比,该软件具有以下优点:1)易损性评估中考虑了破片或弹丸跳弹的影响;2)在导弹破片威胁下的易损性评估中,考虑了部件余度对易损性评估的影响。以上两方面使易损性评估更反映真实情况;3)提供多种易损性评估结果形式。应用中表明,该评估系统功能齐全,对于飞机的易损性减缩设计或生存力增强设计具有指导意义。此外,该评估系统也可用于评估卫星、装甲车、巡航导弹等的易损性。The basic aircraft vulnerability assessment methods were presented. A generic aircraft vulnerability assessment software system was designed and developed. The system consists of five basic modules： data input module, graphical display module, threat input module, calculation method and system setting module and results output module. The system can provide vulnerability assessment results including the probability of kill and vulnerable area of aircraft or components at the single hit and multiple hits by nonexplosive penetrators of arbitrary aspect, the vulnerability at the threat of missile spray fragments, and the plotting of the blast vulnerability envelops at the typical blast planes of aircraft. Compared with the existing assessment software or programs, the developed system has the following advantages： 1） taking account of the ricochet in assessing the aircraft vulnerability at the threat of nonexplosive penetrators or fragments; 2） taking account of the effect of redundant components on the vulnerability at the threat of missile fragments; 3） providing the multiple output formats of assessment results. The above mentioned 1）, 2） advantages make vulnerability assessment more realistic. Application shows that the universal system is helpful to the survivability enhancement or vulnerability reduction design of aircraft, the system can also apply to the vulnerability assessment of cruise missile, satellite and armor vehicle, et. al.
