Abstract
A shaped charge device having at least a double confinement configuration d utilizing a standard shaped charge liner inserted into a hollow cavity in the inner explosive fill. The inner explosive fill is surrounded by an inner confining case which may be made from any metal, ceramic, or composite. The uniqueness of the present invention is the addition of an outer layer of explosive containing an outer confinement case. Also utilized in the device are a booster, and a detonator, held by a centering device, to initiate the device according to standard practice. The device acts to use the outer explosive as a tamping material surrounding the inner confining case material. This will delay the expansion of the inner confinement case and increase the pressure on the liner. Increasing the pressure on the liner will increase the kinetic energy of the resulting penetrator jet.
