Axilinear shaped charge liner with parabolic apex

摘要

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.

1. A shaped charge explosive device having a longitudinal axis that extends along the length of the explosive device from a rearward end to a forward end, comprising:
a liner having a first parabolic liner section located from a apex longitudinal position to a vertex longitudinal position and a second winged liner section extending from said vertex longitudinal position to a winged base end at the forward end of the liner,
said first parabolic liner section formed substantially in a parabolic shape rotated around the longitudinal axis with an apex of the first parabolic liner being located substantially near said longitudinal axis and toward the rearward end of the shaped charge explosive device, and said first parabolic liner section having walls extending circumferentially around the longitudinal axis and extending at an angle C.°/2 from said apex forward toward the vertex longitudinal length of the shaped charge explosive device;said second winged liner section having two winged wall extensions, each winged wall extension being planar symmetric about a horizontal plane with the opposing winged wall extension, each winged wall extension having conical walls partially circumferentially rotated around the longitudinal axis between two winged arc ends and each said winged wall extensions located between said two winged arc ends extending from said vertex longitudinal length contiguous with the first parabolic liner section forward to a forward end of the liner of the shaped charge explosive device, andsaid winged arc ends at corresponding ends of opposing winged wall extensions having a face hollow concavity in the liner material on two opposing sides of the base end of the liner conical profile that extends from the winged vertex longitudinal length to each respective winged arc end for the opposing winged wall extensions, said each face hollow concavity being a parabolic shape extending from each winged arc end to said winged vertex longitudinal length and each face hollow concavity being planar symmetric about a vertical plane; an explosive billet charge that surrounds said first parabolic liner section and surrounds the partially circumferential winged wall extensions with an additional charge located behind the conical apex of said liner; an outer charge body that is an external containment casing surrounding said high explosive billet charge of the shaped charge explosive device and having two outer charge body walls located in the face hollow concavity in the liner material on two opposing sides of the base end of the liner parabolic profile that extends from the vertex longitudinal length to each respective winged arc end for the opposing winged wall extensions; and a detonator coupled to rearward end of high explosive billet charge for initiating detonation of the explosive charge, said detonator providing initiation to the high explosive billet to produce transform the liner into a symmetrical spade shaped projectile configuration.
