    摘要:

    为了考察六硝基六氮杂异伍兹烷(CL-20)基炸药较典型奥克托今(HMX)基炸药的爆炸驱动性能提升幅度,选取典型CL-20基压装混合炸药和HMX基压装混合炸药(JO-8)开展了爆速、爆压、标准圆筒对比实验测试,并设计了预制破片驱动装置和聚能装药战斗部结构,分别开展炸药径向、轴向驱动静爆/静破甲威力实验,实测了爆炸驱动破片的速度以及射流对钢靶静破甲深度。结果表明,CL-20基炸药(密度为1.95 g·cm-3)的爆速、爆压和格尼系数较JO-8炸药(密度为1.83 g·cm-3)分别提高4.8%、16.7%和3.5%。在相同结构下,CL-20基炸药驱动预制破片速度、动能较JO-8炸药分别提高5.1%~7.3%、10.5%~15.1%;在5.5倍装药直径(CD)炸高条件下,装填CL-20基炸药的聚能装药较装填JO-8炸药的静破甲能力提高3.2%~12.6%。

    Abstract:

    A pair of pressed combined CL-20-based and JO-8(HMX-based)explosives are selected to investigate the improvements in the explosion driving performance by using more powerful explosive. This paper presents the test results of detonation velocity, detonation pressure and Gurney coefficient from devices loaded by CL-20-based explosive and JO-8, respectively. Enhanced warhead performance has been demonstrated in static experiments of prefabricated fragment warhead and shaped charge. The results show that the fragment velocity (kinetic energy) driven by CL-20-based explosive is 5.1%-7.3% (10.5%-15.1%) higher than that driven by JO-8. The penetration of shaped charge loaded by CL-20-based explosive is 3.2%-12.6% larger than that loaded by JO-8.
