中文摘要:
针对活性破片终点毁伤威力问题，采用试验研究的方法，分析了活性破片的击穿能力、引燃能力和引爆能力. 结果表明，2.5 g活性破片在870 m/s以上碰撞速度条件下，能可靠击穿8 mm厚LY12硬铝，侵孔直径约为自身直径的1.6~2.0倍；10 g活性破片以大于800 m/s左右速度击穿10 mm厚LY12硬铝板后，可靠引燃航空煤油；10 g活性破片以大于960 m/s左右速度击穿6 mm厚A3钢板后，可靠引爆战斗部装药. 结合活性破片击穿能力可知，活性破片贯穿一定厚度靶板并达到其起爆阈值，就能引燃燃油或引爆装药.
English Summary:
Aiming at the terminal demolition lethality of reactive fragments, the ability of perforation, ignition and detonation for reactive fragments were investigated by experiments in this paper. The result showed that a reactive fragment weighting 2.5 g could perforate the 8 mm-thick LY12 hard aluminum under the collision velocity of 870 m/s, forming penetration holes of a diameter about 1.6~2.0 times diameter of the fragment on target plates. The reactive fragment weighting 10 g could ignite aviation kerosene in the fuel tank shell of 10 mm-thick LY12 hard aluminum at a velocity of more than 800 m/s. Furthermore, it could also detonate the warhead charge after perforating through the 6 mm-thick A3 steel plate at a velocity of more than 960 m/s. Therefore, it can be learned through the analysis of the perforation ability of reactive fragments that reactive fragments perforating a certain thickness of target plates can reliably reach its initiation threshold and ignite fuel or detonate charge.
