EFP战斗部破片场复合技术研究

为提高破片模式的毁伤效能,提出了一种将预制破片群与药型罩破片群相结合的复合破片场成型技术,给出了复合破片战斗部的弹体结构,对破片场的成型过程进行了数值仿真,并进行了实验验证。研究结果表明:采用该技术的战斗部,可形成中心区域为药型罩破片群、外环为预制破片群的复合破片场,且形成的破片场密度均匀,径向散布角达22.5°; 该复合破片场成型技术可应用于巡飞弹战斗部。

Research on Forming Technology of Composite Fragments Field of EFP

In order to enhance the damage ability and effect of fragments mode,a forming technology of composite fragments field was proposed,and the preformed fragments were combined with the liner fragments.The projectile structure of composite fragments warhead was presented.The progress of forming the composite fragments field was simulated,and the forming effects were validated by experiments.The results show that a composite fragments field can be formed by the technology.Liner fragments are in the central region of the field,and the preformed fragments are distributed in the outside ring region.Fragments are distributed equally in the field,and the radial dispersion angle of fragments reaches to 22.5°.The forming technology of composite fragments field can be used in warhead of loitering missile.
