Wave Shaping in the MRL (Materials Research Laboratories) 38 MM Shaped Charge.

Abstract

The effect of wave shaping on the MRL 38 mm shaped charge is considered. A simple extension of the Pugh, Eichelberg and Rostoker theory is used to consider the effect of the both spherically diverging and spherically converging detonation waves on jet performance, and then a more sophisticated analytical approach is used to look at the expected increase in jet-tip velocity produced by a conical detonation wave. This predicted jet-tip velocity is compared with the result from a HELP-code simulation of the same event. Numerical problems occurred in the latter, but both methods predict a considerable increase in the velocity of the jet-tip. Some problems involved with the experimental formation of a conical detonation wave are the briefly discussed. (Author)
