Abstract

An apparatus for storing and/or shipping explosive components, such as shaped charges, is generally described. In an embodiment, the apparatus includes a shielding assembly. The shielding assembly may include a shielding panel having a body made of metal foam and an aperture formed within the body. In an embodiment, the body is sandwiched between an upper and a lower layer. The shielding panel is configured to receive a shaped charge. Thus, the apparatus is capable of at least preventing and/or limiting ballistic transfer in the event of detonation of a shaped charge.

First claim

What is claimed is:

1. An apparatus for storing and shipping an explosive article, comprising:
a shielding assembly comprising a shielding panel comprising a body formed of a metal foam, wherein
the shielding panel comprises an upper layer, a lower layer, an inner layer positioned between the upper layer and the lower layer, and an aperture extending through at least the upper layer and at least a portion of the inner layer, wherein the aperture is configured for receiving a shaped charge, and
the shielding assembly is adapted and configured to trap and absorb shrapnel and shock wave impulses in the event of detonation of the shaped charge.

2. The apparatus of claim 1 , least wherein an upper edge of the shaped charge is below an upper surface of the upper layer of the shielding panel when positioned in the shielding panel.

3. The apparatus of claim 1 , wherein an upper edge of the shaped charge is above an upper surface of the upper layer of the shielding panel when positioned in the shielding panel.

4. An apparatus for storing and shipping an explosive article, comprising:
a container having a top, a bottom and four sides; and
a shielding assembly positioned within the container,
wherein the shielding assembly comprises a shielding panel, the shielding panel comprising a body formed of a metal foam,
wherein the shielding panel comprises an upper layer, a lower layer, an inner layer positioned between the upper layer and the lower layer, and an aperture extending through the upper layer and at least a portion of the inner layer, wherein the aperture is configured for receiving a shaped charge, and
wherein the shielding assembly is adapted and configured to trap and absorb shrapnel and shock wave impulses in the event of detonation of the shaped charge.

5. The apparatus of claim 4 , wherein an upper edge of the shaped charge is below an upper surface of the upper layer of the shielding panel when positioned in the shielding panel.

6. The apparatus of claim 4 , wherein an upper edge of the shaped charge is above an upper surface of the upper layer of the shielding panel when positioned in the shielding panel.

7. The apparatus of claim 4 , further comprising a protective layer, wherein the shielding assembly is paired with the protective layer.

8. The apparatus of claim 7 , further comprising a non-rigid container having an open end and a closed end, the non-rigid container being configured for receiving an inner protective container, wherein the shielding assembly in combination with the protective layer is positioned within the inner protective container.

9. The apparatus of claim 4 , wherein the shielding panel comprises:
a plurality of shielding panels, wherein
each shielding panel of the plurality of shielding panels is oriented within the container in a stacked arrangement, and
an upper surface of the shielding assembly is positioned within the container in an orientation facing an upper surface of an adjoining shielding assembly.

10. The apparatus of claim 4 , further comprising an inlay positioned adjacent to an opening of the shaped charge, such that when the shaped charge is positioned within the aperture of the shielding panel, the inlay is configured to prevent jet formation from the shaped charge upon inadvertent detonation of the shaped charge.

11. An apparatus for storing and shipping an explosive article, comprising:
a container having a top, a bottom and four sides;
a non-rigid container positioned within the container, the non-rigid container having an open end and a closed end; and
a shielding assembly positioned within the non-rigid container, wherein the shielding assembly comprises a shielding panel and a protective layer paired with the shielding panel, the shielding panel comprising a body formed of a metal foam, an upper layer, a lower layer, an inner layer formed from the body and positioned between the upper layer and the lower layer, and an aperture formed in the body and configured for receiving a shaped charge,
wherein the shielding assembly is adapted and configured to trap and absorb shrapnel and shock wave impulses in the event of detonation of the shaped charge.

12. The apparatus of claim 11 , wherein the metal foam comprises aluminum, steel, iron, alloys thereof, or combinations thereof.

13. The apparatus of claim 11 , wherein the metal foam comprises a highly porous, irregular-shaped pattern, which reduces the overall weight while maintaining structural integrity to trap and absorb the shrapnel.

14. The apparatus of claim 11 , wherein the aperture is one aperture of a plurality of apertures and the plurality of apertures is positioned in the shielding panel in a circular arrangement.

15. The apparatus of claim 14 , wherein the shaped charge has a plurality of sides and is positioned in the shielding panel such that at least one side of the plurality of sides is in direct contact with at least the inner layer.

16. The apparatus of claim 11 , wherein the shaped charge comprises an opening and an external surface positioned opposite the opening, the shaped charge being positioned within the shielding panel, such that opening and the external surface are positioned within at least a portion of the inner layer.

17. The apparatus of claim 11 , wherein the shielding panel further comprises a jet interrupter positioned therein.

18. The apparatus of claim 17 , wherein the shaped charge is one of a pair of shaped charges, wherein each shaped charge of the pair of shaped charges comprises an opening and the pair of shaped charges is arranged such that the openings of the pair of shaped charges are in a face-to-face arrangement and the jet interrupter is positioned between the openings of the pair of shaped charges, the jet interrupter being configured to at least inhibit or limit transference of a jet formed from one shaped charge or both shaped charges of the pair of shaped charges upon inadvertent detonation of one shaped charge or both of shaped charges of the pair of shaped charges.
