Shaped charge warhead with mechanical means for preventing rotation

Abstract

Mechanical interference between a cast explosive material and a casing prnts rotation of the cast explosive material during machining thereof and improves symmetry and performance of the shaped-charge warhead. The cast explosive material may be keyed to the casing by flowing portions of the explosive material into a plurality of cavities in the casing before curing. Alternatively, pins may extend inward from the casing into the explosive material which surrounds them when cast and resists relative motion therebetween when cured. Alternatively, the explosive material may be pre-cast into an appropriate shape, cured and pressed into the casing. Protuberances to fit into holes in the casing or indentations to fit over pins extending into the casing may be formed on the pre-cast explosive. Engagement between the protuberances or indentations and the holes or pins respectively is attained when the explosive material is pressed into the casing.
