DTIC ADA604020: An Empirical Shaped Charge Jet Breakup Model

Much of the increase in penetration capability of copper lined shaped charges has been due to changes that increased copper jet breakup time. This has been accomplished largely independent of the growing understanding of breakup phenomenology. This report discusses an empirical shaped charge jet breakup model and provides significant experimental confirmation over a broad range of velocity gradients. Analysis using this model has proved to be useful in order to explain observed performance and to identify undesirable characteristics.
