聚焦式战斗部攻击下飞机的易损性计算

Calculation on the Vulnerability of Aircraft from A Focusing Warhead

飞机生存力已成为军用飞机设计的主要技术指标之一,飞机易损性计算的主要目的是评估飞机生存力,为飞机生存力增强设计提供理论指导。以模拟现代空战中主要使用的聚焦式战斗部的毁伤元真实飞散特性为基础,考虑冲击波超压的毁伤效应和球形、方形毁伤元对飞机的洞穿作用,以战斗部静态飞散角作为设计参数,建立了聚集式战斗部的威力场。研究了聚焦式战斗部威力场内不同毁伤元对飞机的多击中易损性,同时给出了计算实例,与非聚焦战斗部杀伤结果对比表明:聚焦式战斗部对飞机有更高的杀伤概率。

The survivability has been one of the significant technical index formilitary aircraft,and the primary purpose of calculation on vulnerability for aircraft is to evaluate survivability and provide theoretical guidance for enhancement of survivability.This contention about this paper is to be erected power field of focusing warhead,considering demolish of waves for explosions and piercing of global and quadrate devastating element,looking upon static dispersion angle as a design parameter,through simulating flight of the fragment of the focusing warhead in modern airwar.This paper studies vulnerability of multiple hits different devastating elements in power filed of focusing war-head.An example for calculation is showed,compared with conventional warhead that a focusing warhead can make a higher damaging probability for aircraft.
