寻的制导导弹攻坚战斗部随进率研究

寻的制导导弹末段弹道采用比例导引制导律,当打击坚固工事时,在保证命中精度的前提下,落角散布较大.此外,主战斗部在开孔过程中如果遇到钢筋未被切断,则随进战斗部会被阻挡,从而降低随进战斗部的成功随进率.分析了导弹的落点分布、落角散布、目标内部钢筋结构、射流与随进战斗部尺寸因素对攻坚战斗部随进率的影响,利用蒙特卡洛随机抽样方...

Research on Following Penetrating Rate of Homing Guided Missile's Bunker Blaster Warhead

Proportional navigation guidance law is used for the terminal trajectory of homing guided missile.While attacking a reinforced fortification,the falling angle dispersion is relatively large so as to ensure a higher hitting accuracy.In addition,the following warhead may be blocked if a reinforced steel bar is not cut off during the opening process of the main warhead,and therefore the successful following penetrating rate of the following warhead is lowered.The effects of falling point distribution and falling angle dispersion of missile,reinforced structure within target,jet current,and size of following warhead on the following rate of bunker bluster warhead were analyzed.The successful following rate of the following warhead penetrating reinforced target was calculated using Monte Carlo random sampling method.The results show that the following rate is direct proportion with jet diameter and inverse proportion with the size of following warhead and falling angle.The following rate is maximum when the missile shoots the target vertically.The research result could give a theory support to the model development of related weapon systems.
