Abstract

A lightweight linear shaped charge for explosive cutting and penetration of target, which includes a plastic linear housing in the form of a concave channel with an inverted "V" shaped metallic liner mounted within the concave channel. An explosive charge is shaped and held between the plastic housing and the metallic liner. Upon detonation of the explosive charge an explosive jet of the metallic liner is generated to cut and penetrate the target. Also, the plastic linear housing may be extended downward a short standoff distance of approximately 0.5 to 1 inch for optimum cutting and penetration of the target.

Claims

1. A lightweight linear shaped charge for explosive cutting and penetration of a target, which comprises:

a plastic linear housing having a flat top connected along its length to two opposing arms to form a hollow concave channel therebetween with the concavity opening downward toward the target for cutting and penetration;

a metallic liner, having an inverted "V" shape, mounted within the concave opening and attached along the interior length of each opposing arm, with the top of said inverted "V" shape extending lengthwise along the interior of said linear housing beneath said flat top and above the target, so as to form a hollow interior space between said metallic liner and said plastic housing;

an explosive charge shaped and held within said hollow interior space between said metallic liner and said plastic housing; and

a detonator holder connected to said plastic housing and holding a detonator therein for initiation of said explosive charge to make an explosive jet of said metallic liner for cutting and penetration of the target.

2. The lightweight linear shaped charge of claim 1, wherein each of said opposing arms are integrally extended a short distance outward and downward toward the target.

3. The lightweight linear shaped charge of claim 2, wherein the the extension of each of said opposing arms is for a distance of approximately 0.5 to 1 inch.
