约束状态下聚能杆流对混凝土作用的实验研究

聚能杆流是多级串联战斗部次级装药的常用聚能侵彻体.基于两种典型的聚能装药结构,设计加工了有不同直径和深度预制约束孔的C35混凝土靶板,开展了(Φ60mm亚半球和K装药在不同约束状态侵彻毁伤混凝土对比实验研究.结果表明,两种聚能杆流都可在混凝土孔约束状态下形成大且深的侵彻孔;随约束孔径增大,侵彻深度先减小而后增加;随约束...

Experimental Study of Constraint Effect on Shaped Charge Jet Penetration in Concrete Targets

Jetting projectile is a kind of shaped charge that can be used as the second part of a tandem warhead system. Two typical shaped charges, hemispherical liner charge (HLC) and K charge (KC), that can form jetting projectile were designed. C35 concrete targets with hole constraints which have different diameters and heights were prefabricated. Experiments were carried out using above charges in predrilled hole and in the air. Experimental results show that all two shaped charges can form jetting projectile, also can form deep holes with reasonable large diameter. Comparing with HLC, the penetration depth of KC is much larger, while the diameter of HLC is much larger. But comparing with the results obtained in the air, the penetration depth of HLC is effected by constraints, while the KC changes present more stability. Above results can provide some evidences for designing second part of tandem warhead system.
