飞机类目标毁伤效果评估方法研究

Research on Damage Effect Assessment Method of Aircraft Targets

在飞机结构特性、战斗部破片毁伤场等毁伤效能评估基本要素分析基础上,建立了一种破片式战斗部作用下的飞机类目标毁伤效果评估模型。通过对飞机目标结构分析,得到适用于毁伤概率计算的目标几何特征、毁伤模式等易损性信息,结合破片动态飞散特性,给出了破片命中舱段的计算方法,最终通过计算破片对飞机目标的毁伤概率定量描述飞机的易损性。基于此数学模型开发了毁伤评估仿真系统,并通过某型飞机实例验证其可行性。

A damage assessment model of aircraft targets under fragmentation warhead was established based on the analysis of the basic elements of damage effectiveness evaluation such as aircraft structure and warhead fragmentation damage field. The information of target geometry and damage mode suitable for damage probability calculation is obtained by analyzing the results of aircraft targets. The calculation method of hit point of fragments is given combining with the dynamic dispersion characteristics of fragments. Finally the aircraft vulnerability is quantitatively described by calculating the damage probability of fragments to the whole aircraft target. A damage assessment simulation system is developed based on the mathematical model,and its feasibility is verified by certain type aircraft flight example.
