本文系美国加里福尼亚大学劳伦斯利维莫尔实验室关于多级空心装药设计的状况,着重叙述多级空心装药设计的各个方面如何影响射流特征的分析和研究工作。证实确定药型罩几何形状的分析研究法对得到具有可控的速度梯度的射流和高的效率是有效的。还证实射流截断器、其它补助元件与控制的药型罩厚度一起有助于使射流和杵体之间明显断开并使第二级 This article is based on the design of multistage hollow charge at the Lawrence Livermore Laboratory at the University of California, the University of California, focusing on the analysis and research of how various aspects of multistage hollow charge design affect jet characteristics. Analytical methods that confirm the geometry of the drug shields are effective in obtaining jets with a controlled velocity gradient and high efficiency. It was also confirmed that, together with the controlled thickness of the medicament cover, the jet cutter, the other supplemental elements, helped to clear the gap between the jet and the body and allow the second stage
