Inventor: Robert E. Eckels Title: Shaped Charge With Enhanced Penetration ABSTRACT OF THE DISCLOSURE A diverging, smooth wall stand-off for an explosive shaped charge aligns generated gases into smooth flow enhancing of the formed jet substantially increasing the jet length effec- tively, the jet penetration, increasing the cleanliness of the developed hole, and the like. The shape of the stand-off to produce the enhancement is a frusto conical tubular device, and preferably extends from about 13° included closing angle at about 1.5 conical cavity diameters to about 30° included closing angle at about 0.6 conical cavity diameters. The base of frusto-conical stand-off coincides with the base of the cavity of the shaped charge and the small end of the stand-off has an area of about two-thirds of the base. A small range on either side of the optium or preferred frusto-conical stand-off provides a highly effective enhancement for the shaped charge.
