selective shaped charge

The study and application of the concentrated energy charge are introduced in this paper.

介绍聚能爆破的研究与实践成果,重点叙述“聚能弹”研制及其在青藏高原多年冻土地带工程爆破中的实际应用效果。

Shaped charges of the same sort are underbalance perforated in three kinds of sandstones in the lab.

在实验室条件下,用同种聚能射孔弹在3种不同砂岩上进行负压射孔,然后进行流动测试。

The test data are adopted along with the-characteristics of jets produced by shaped charges to analyze the forming process of perforation channels and damage mechanism of perforatio.

射孔实验后对贝雷砂岩靶进行了核磁共振等实验,结合聚能射孔弹产生射流的特点,分析了射孔道的形成过程及射孔损害机理。

Four parameters affecting penetration length of shaped charge are cone angle,wall thickness of shaped charge liner,shaped charge structure and casing thickness.

在聚能射孔弹的研究中应用正交试验方法,以确定聚能射孔弹各结构因素对性能的影响及主要因素的交互作用对性能的影响。
