不同内核材料PELE弹丸对多层靶穿甲实验研究

Experimental Study on Multi-Layered Target Penetration of PELE with Different Cores

为确定内核材料对PELE弹丸横向效应的影响,进行了内装聚乙烯、聚碳酸酯、聚四氟乙烯、聚丙烯、聚氨酯材料的横向效应弹丸(PELE)对4层间隔靶的侵彻试验,获得了不同方案PELE弹对主靶的穿孔孔径、间隔后效靶面的破片分布.实验结果表明,聚四氟乙烯作内核材料的PELE弹穿靶后形成的破片数和飞散角明显大于其它材料;PELE弹穿靶后形成的破片飞散角在主靶有一定斜置角时增大.

To study the influence of filling material on lateral effect of penetrator with enhanced lateral efficiency（PELE）, the experiments of penetrating into four layered target by a steel shell PELE filling with different cores： polyethylene, polycarbonate, teflon, polypropylene and polyurethane penetrate, were carried out. The perforating diameters of main armor and fragments distributions on witness target were obtained in correspondence with different cores. The experiments demonstrate that PELE with teflon core can generate more fragments and spread a larger dispersion angle. The fragment dispersion angle of PELE increases once the main armor is in a position with 38° oblique angle to the ground.
