| 中文摘要: |
| 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；随约束孔深增加,侵彻深度增加,K装药侵彻深度更大；但与空气对比,亚半球装药侵彻深度受约束影响较大,K装药则变化较小,比较稳定。实验结果为多级串联战斗部次级装药结构的选择提供了依据。 |
| 英文摘要: |
| 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. |
