Abstract
A method and apparatus for controlling the final shape of an explosively formed penetrator, in which a liner is explosively accelerated to high velocity to impact upon a mandrel and form a penetrator whose final shape, surface and mass distributions about its axis and along its length are determined by the mandrel shape. The shape of the mandrel can be varied to produce penetrators of optimal shape, depending upon the intended penetrator use. Such shape definition permits the dynamic formation of penetrators which have favorable static margins, which can be fin or spin stabilized, and which can have favorable shapes and mass distributions for effective target penetration.
