钻地弹指反地下坚固硬目标的侵彻战斗部,由坚硬的金属壳体、高威力的爆炸装药和智能引信组成。提高侵彻深度通常有两种基本的方法。第一种是先用空心装药打出一个穿透混凝土层或泥石构件的孔眼,然后使直径较小的随进弹头在孔内爆炸。这种战斗部通常叫做多级串联战斗部。另一种是使战斗部加速到超音速,靠其动能增强化学能的作用。例女口法国宇航公司240千克重的激光制导空地导弹AS-30L在距目标10～11千米处发射,其动能战斗部以1.4马赫的速度撞击目标时,侵彻能力可以提高一倍,能够侵入2米深的混凝土中。动能弹要求具有
Ground bouncing means the anti-ground hard-penetrating target that penetrates the warhead. It consists of a rigid metal shell, high explosive charge and intelligent fuse. There are usually two basic ways to improve penetration. The first is to use a hollow charge to drill a hole that penetrates the concrete or debris and then make an advancing warhead of smaller diameter explode in the hole. This warhead is often called a multi-stage tandem warhead. The other is to accelerate the warhead supersonic speed, by its kinetic energy to enhance the role of chemical energy. Example Female French Aeronautic Corporation 240 kg heavy laser guided air missile AS-30L at a distance of 10 to 11 km from the target, its kinetic warhead hit the target at Mach 1.4, the penetration can be doubled to be able to Intruded into concrete 2 meters deep. Kinetic bomb requirements have
