Abstract: An explosive breaching device is made from a surplus bomblet. The bomblet includes a shaped-charge liner, a steel fragmentation case with an open end, explosive material disposed between the shaped-charge liner and the steel fragmentation case, and a fuze. The fuze of the bomblet is removed and a shock-attenuating case is fixed adjacent to and coaxial with the steel fragmentation case. The shock-attenuating case may be made of a material having a speed of sound that differs from the speed of sound in the steel fragmentation case. A mild steel housing is fixed around the shock-attenuating case. A retaining sleeve may be fixed to the mild steel housing. The explosive breaching device may be mounted in an aiming device to direct the shaped-charge jet in a desired direction.

Abstract: This invention is a shaped explosive device with a liner that has a parabolic apex, which can produce a purely planar symmetric jet. The half pipe liner in the present invention has a parabolic apex or pole toward the aft end, a “V” notch on each side of the concave wings toward the fore end, and liner base end on each wing. Liner resembles two angled half sections of thin walled pipe butted together at the apex or pole, and when properly driven by a high explosive will produce a spade shaped stretching Munroe jet that erodes a deep elongated hole in a target. Alternatively, this invention is a shaped explosive device with a liner that produces a single combination jet consisting of a forward rod portion and rearward flattened spade shaped portion, this jet has a velocity gradient form tip to tail. When applied in a circular or other polygonal shaped array the Axilinear shaped charges will produce extremely large diameter holes greater than the overall diameter of the array.
Abstract translation: 本发明是具有抛物线顶点的衬垫的成形爆炸装置，其可以产生纯平面的对称射流。 本发明中的半管衬套具有朝向后端的抛物线顶点或极，朝向前端的凹翼的每侧上的“V”槽口以及每个翼的衬垫基端。 衬垫类似于薄壁管的两个有角度的半部分，在顶点或杆处对接在一起，并且当被高爆炸物适当地驱动时，将产生一种铲除形状的延伸的Munroe射流，其侵蚀目标中的深长的孔。 或者，本发明是一种具有衬套的成形爆炸装置，其产生由前杆部分和后扁平的铲形部分组成的单个组合射流，该射流具有尖端到尾部的速度梯度形式。 当应用于圆形或其他多边形阵列时，双线形电荷将产生大于阵列总直径的非常大的直径孔。

Abstract: A shaped charge includes a casing defining an interior volume, wherein the casing is prepared by sintering a metal powder or a mixture of metal powders; a liner located in the interior volume; and an explosive between the liner and the casing. A method for manufacturing a shaped charge casing includes the steps of mixing a metal powder or a metal powder mixture with a binder to form a pre-mix; pressing the pre-mix in a mold to form a casing green body; heating the casing green body to a first temperature to vaporize the binder; raising the temperature to a second temperature in an inert or reducing atmosphere to sinter the metal powder or the metal powder mixture to produce the shaped charge casing.

Abstract: A system where a group of substantially universal pre-manufactured explosive pellet assemblies are provided for on-site forming of shaped charges. That is, a specifically tailored liner may also be separately provided to the worksite/oilfield and combined with any one of the pellet assemblies so as to form a shaped charge having characteristics that are determined by the particular liner used. In this manner, hazardous shipping of fully assembled shaped charges may be avoided while at the same time allowing the operator a full range of shaped charge performance options based on the availability of uniquely tailored performance determinative liners that are also provided to the oilfield location.

Abstract: An improved shaped charge apparatus and method of manufacturing is provided including a composite wave shaper, a main charge, and a metal liner. An exemplary embodiment's wave shaper can be adapted to manipulate a shock front so that an interaction of the main charge and the metal liner occurs lower along the liner's profile such that the apparatus restricts an initial elongation of a resulting jet. An embodiment can have a thickness of the metal liner sufficient to provide a mass necessary to generate a first size diameter aperture in a target material. An embodiment an also provide a combination of the liner thickness and shock interaction point resulting in the jet having an improved length to diameter ratio among other advantages. An embodiment of the invention can also provide other advantages such as an explosive to mass ratio of less than 3 or 2 to 1.
