含能破片战斗部对导弹目标的等效毁伤效应研究

Equivalent damage study of missile due to energetic fragment warhead

为研究战斗部对导弹目标的毁伤效应,在导弹功能、结构和毁伤机理的基础上,确定了导弹目标的毁伤级别和各舱段的毁伤准则。含能战斗部由钨合金、含能材料、尼龙弹托和底座组成。含能材料由铝镁合金粉、硝酸钡和聚四氟乙烯组成,通过在真空容器中高温烧结制备。利用12.7 mm机枪进行穿甲和引燃试验,依次射击25 mm/60°均质装甲板、导弹设备舱和燃料舱模拟靶,并用高速摄影记录战斗部对油箱的毁伤过程。试验结果表明含能战斗部兼有侵彻能力和引燃纵火能力。

In order to study the damage effect of a warhead on a missile target,damage levels and damage criterion of every component of the missile are given based on the function,structure and damage mechanism of the missile.The energetic warhead is composed of tungsten alloy,energetic material,nylon sabot and plastic base.The energetic material are prepared by high-temperature sintering in a vacuum container,including of aluminum magnesium alloy powders,barium nitrate and PTEE.The armour piercing and ignition experiments are carried out using a 12.7 mm machine gun and acting on 25 mm/60°homogeneous armor plates,a missile equipment module simulation target,and an armed fuel tank simulation target.The penetration process against an oil tank is recorded by a high-speed camera.Experimental results show that the energetic warhead has capability of penetration and ignition.
