Shaped charge liner method and apparatus
One or more aspects of the present disclosure relate to a method of at least partly manufacturing a liner for a linear shaped charge. The method can include coating each of a plurality of metal particles with a non-metal, to form a plurality of coated spherical particles; mixing, without a solvent, the plurality of coated spherical particles with a polymer binder and at least one of: a filler, a dry lubricant, or a wet lubricant, until a flexible material is formed with the plurality of coated spherical particles dispersed homogeneously in the polymer binder and the flexible material has a mass of at least 5,700 kg per cubic meter volume of the flexible material; and at least partly forming a liner for the linear shaped charge from the flexible material.

PRE-DEFINED RECESS
The invention relates to a process for forming a pre-defined recess in a cured or cast explosive composition comprising the steps of: i) providing a female mould, ii) providing a male former, and locating said male former proximate to the female mould to create a gap between said male former and female mould, iii) forming an admixture of a curable/castable explosive composition, charging the gap with the admixture of explosive composition, causing the cure or cast of said curable/castable explosive composition, removing the male former to furnish a cured or cast explosive composition with a pre-defined recess.

Shaped charges for focusing a fluid mass
Provided herein are shaped charges for focusing a fluid mass and related methods of using the shaped charges for disruption of an explosive target. The shaped charge comprises a plastic shell having a special geometric shape configured to support a shape-conforming explosive. A cylindrical plastic body has an interior volume for containing a fluid and the plastic shell. The plastic body closed distal end has a geometric shape that is substantially matched to the shape of the plastic shell.

Shaped charge with self-contained and compressed explosive initiation pellet
A shaped charge comprises a case including a wall that defines a hollow interior within the case. The wall includes an external surface and an internal surface. An explosive load is disposed within the hollow interior and positioned adjacent at least a portion of the internal surface. An initiation point chamber extends at least partially between the external surface and the internal surface of the wall. At least one self-contained, compressed explosive initiation pellet is contained within or adjacent the initiation point chamber. An exposed perforating gun carrier utilizing the shaped charge, and a method of using and producing the same are also contemplated.
FIRING STAND FOR SHAPED CHARGES
A firing stand (30) for mounting a plurality of shaped charges. The firing stand (30) can be configured by a user between a transport configuration in which shaped charges are stored for transport, and at least a first firing configuration from which shaped charges can be deployed. Inter-connected rotating panels (31) may be used to provide user configurability to the firing stand (30), with shaped charges optionally being mounted in panel apertures (36). The firing stand provides for rapid and configurable deployment of multiple shaped charges.
SHAPED CHARGE LINER AND METHOD FOR PRODUCTION THEREOF
The present invention relates to a liner for shaped charge for penetrating hard targets, wherein the liner comprises i) a carrier having a density below 9500 kg/m3; and ii) a coating deposited on said carrier comprising at least one metal and/or metal oxide, wherein the coating has a density greater than 10000 kg/m3; wherein the thickness ratio of the carrier to the coating ranges from 100:1 to 1:1, and wherein the oxygen content in the coating is less than 100 ppm atomic. The invention also relates to a method of producing such shaped charge liner and the use 0 thereof in a projectile for penetrating a hard military target.
