战斗部最佳起爆延时的计算模型及其应用研究

为确定战斗部最佳起爆延时,通过巧妙地建立坐标系,提出一种考虑破片速度指数衰减的计算模型.对共面交会条件下战斗部最佳起爆延时进行计算,得到了战斗部最佳起爆延时随弹目交会角的变化规律,及威力半径为9m时战斗部的作用范围.结果表明,随着弹目交会角的增加,最佳起爆延时存在一个极大值,且战斗部的作用范围趋近于战斗部威力半径.

Calculation Model of Optimum Delay Time of Detonation of Warhead and Its Application

To determine the optimum delay time of detonation of warhead,a model which took exponential attenuation of fragments velocity into account,was proposed through establishing coordinate system skillfully.When the target and the warhead were in the same plane,the relationship between the optimum delay time of detonation and the crossing angle was obtained.At the same time,the effective area of warhead was gained when the lethality radius of warhead was 9 m.The results show that,with the increase of crossing angle,the optimum delay time of detonation will reach the maximum value.The effective area of warhead will approach the lethality radius of it.
