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.

1. A shaped charge jet disrupter comprising, (a) An elongated central support, with a first tip end and second base end;(b) a plurality of general hemi-circular discs extending generally perpendicular from said central support, which discs are spaced along the length of the central support in a staggered manner;(c) wherein the disc closest to the first tip end of the central support has the smallest radius and the radius of each disc thereafter toward the second end is greater, such that the outline formed by a outer edges of the discs forms a general cone shape;(d) which general cone shape corresponds to the interior of the hollow open mouth of the shaped charge. 2. The shaped charge jet disrupter of claim 1, wherein there are at least 4 generally hemi-circular discs staggered along the length of the central support. 3. The shaped charge jet disrupter of claim 1, wherein the number of generally hemi-circular discs staggered along the length of the central support is selected from the group consisting of 4, 5, 6, and 7. 4. The shaped charge jet disrupter of claim 1, wherein there is a completely circular disc located at the second base of the elongated central support, which disc provides a means to secure the disrupter within the hollow open mouth. 5. The shaped charge jet disrupter of claim 1, wherein said disrupter is manufactured of a material selected from the group consisting of a plastic, a metal, a composite, and glass. 6. The shaped charge jet disrupter of claim 1, wherein said elongated central support is cylindrical in shape, with the first tip end thereof rounded. 7. The shaped charge jet disrupter of claim 1, wherein said elongated central support is a thin, triangular in cross-section, wedge that has a rounded tip. 8. The shaped charge jet disrupter of claim 7, wherein said wedge has a base end opposite to its rounded tip, which base end has a length that is just less than the inner diameter of the hollow open mouth of the shaped charge. 9. A method for disrupting and significantly mitigating the penetrative capability of a jet emitted from the generally hollow open mouth of a shaped charge, comprising, (a) placing within said generally hollow open mouth of said shaped charge a disrupter;(b) wherein, said disrupter comprises an elongated central support, with a first tip end and second base end;(c) a plurality of general hemi-circular discs extending generally perpendicular from said central support, which discs are spaced along the length of the central support in a staggered manner;(d) wherein the disc closest to the first tip end of the central support has the smallest radius and the radius of each disc thereafter toward the second end is greater, such that the outline formed by the outer edges of the discs forms a cone shape;(e) which cone shape corresponds to the interior of the hollow open mouth of the shaped charge; and(f) wherein the first tip end of the said central support is adjacent to the central point of the interior of hollow open mouth of the shaped charge;(g) such that when the shaped charge is detonated, the disrupter will disrupt and significantly mitigate the penetrating force of the jet therefrom. 10. The method for disrupting and significantly mitigating the penetrative capability of a jet emitted from the generally hollow open mouth of a shaped charge of claim 9, wherein said disrupter is fastened to a container holding the shaped charge.
