摘要
通过飞机蒙皮崩落损伤典型事例分析和理论计算等方法,研究了飞机遭爆炸性武器打击后形成蒙皮崩落损伤的机理,重点讨论了爆炸距离、战斗部装药量对蒙皮崩落损伤的影响,建立了相应的计算公式,可为飞机战伤预测、战伤评估、抢修预案制定及飞机战斗生存力设计提供依据。研究结果表明:随着爆炸距离增大或战斗部装药量减小,蒙皮崩落损伤尺寸迅速减小。当战斗部装药量(装药量过大除外)一定,爆炸距离增大到一定程度时,爆炸冲击波就不能引起蒙皮崩落损伤;在此条件下,若爆炸距离趋于零,蒙皮崩落损伤尺寸会趋于一个常数。
By means of analyzing typical examples of airplane skin＇s avalanche damage and theoretic computing etc,the mechanism of avalanche damage of skin appearing after the airplane is stricken by volatile weapon is studied,the effect of explode distance,powder mass of warhead upon skin＇s avalanche damage is discussed mostly,and the relevant computing formulae are brought forward in this paper.All of these can be helpful for airplane battle damage forecast,assessment,establishing ABDR advance plan and design of survivability.The result shows that the size of skin avalanche damage reduces rapidly with the explode distance augmenting or the powder mass of warhead reducing.When the powder mass is invariable（except that the powder mass is too big）and the explode distance augmenting to some quantity,the skin＇s avalanche damage by blast shockwave will not appear.Under this condition,if the explode distance approaches 0,the size of skin＇s avalanche damage will approach some constant.
