活性破片终点毁伤威力试验研究

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. 

Experimental Study on Terminal Demolition Lethality of Reactive Fragments

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.
