摘要
通过实验比较了理想球形钨珠和经历爆轰驱动的钨珠(初始为球形)主要终点弹道性能的差异,结果表明:(1)钨珠经爆轰驱动后,发生轻微的质量损失和变形现象,直径6.0 mm和7.5 mm钨珠的质量损失平均为8.4%;(2)对于理想球形钨珠,在同一初始速度条件下,衰减系数为常数,空气阻力系数仅与初始速度有关,两者成线性关系,而对于经历爆轰驱动的钨珠,衰减系数不再为常数,空气阻力系数与飞行速度有关,两者成线性关系;(3)爆轰驱动明显降低了钨珠的穿甲能力,但长距离飞行后,钨珠仍具有较强的穿甲能力,是破片式战斗部或杀爆战斗部较理想的选择。
Tests were performed to investigate the influence of detonation driving on terminal ballistic effects of tungsten spheres. The experimental results show that （1） tungsten spheres are slightly deformed and damaged as a result of the high shock pulse during detonation, the average mass loss of tungsten spheres with a diameter of 6.0 mm and 7.5 mm is 8.4% ; （2） for ideal tungsten spheres, the attenuation coefficient of velocity is constant, the air drag coefficient is a linear function of initial velocity, whereas for tungsten spheres formed by a warhead, the attenuation coefficient of velocity is not constant, the air drag coefficient is a linear function of flight velocity; （3） the deformation and damage of tungsten spheres exerts a obvious influence on the perforation thickness, for tungsten spheres with a diameter of 7.5 mm, experiments and calculations confirm a 35%-reduction in ballistic limit perfora- tion thickness.
