Abstract

A simple, inexpensive, device and method of use thereof for disrupting the jet of a shaped charge and thereby significantly reducing the penetrating capability by over 90% thereof; thus providing a means to mitigate the damage caused by the premature or accidental jetting of the shaped charge. The device has a central support, along which radiate a plurality of increasing radius, generally hemi-circular, thin discs—such that the outline of the disc edges thereof form a cone that models the interior of the hollow open mouth of the shaped charge—importantly, the discs are staggered along the length of the central support. The device, which can be molded of inexpensive plastic, must be lodged fully within the hollow open mouth of the shaped charge at the time of the premature or accidental jetting—to provide the desired mitigation.
