摘　　要：针对实际作战中飞机会受敌方导弹破片的威胁以及受破片打击后会产生二次杀伤效应的情况，提出了一种考虑了导弹破片威胁和二次杀伤效应的飞机易损性评估模型。以导弹破片分布规律及破片对飞机致命性部件杀伤准则为基础，分析了破片与致命性部件交汇点及入射角的确定方法，研究了非余度部件和余度部件二次杀伤效应的计算，结合飞机杀伤树图建立了飞机易损性评估模型，最后进行了某飞机模型的易损性评估仿真试验。仿真试验结果表明，该模型的评估结果与实际比较吻合，可以有效地解决受导弹破片攻击和二次杀伤威胁的飞机的易损性评估问题，对于飞机的生存力增强设计、导弹杀伤效能评估等都具有指导意义。Considering that aircrafts in battle are mostly hit by the fragments from missiles and the of subsequent destruction, a practical aircraft vulnerability assessment model was proposed. of fragment trajectories and rules of killing critical components, the intersection point and hit can bring the effect Based on the analysis the angle of incidence were determined. The method for calculating the second destruction effect of non-redundant and redundant compo- nents was researched and the vulnerability assessment model was established based on the damage tree of the air- craft. In the end, several numerical examples were given. The simulation results show that the assessment model is effective and feasible, which can provide important references for aircraft survivability design and missile effective- ness evaluation.
