【摘要】 对聚能装药多层药型罩的特性进行了理论分析，并对铜铝双层罩所形成的射流进行了Ｘ光测试，结果表明，其射流头部速度及速度梯度均优于单铜罩，是提高聚能射流速度的一种有效技术途径。更多还原

【Abstract】 The specific property of shaped charge multilayer liner is studied theoretically in this paper.And the jet from shaped charge with Cu-Al bimetallic liner is determined with X-ray experiment.The results show that the bimetallic liner is superior to copper one in jet head velocity,jet velocity gradient,indeed,it is an effective means to increase jet velocity by using multilayer liner.更多还原
