Abstract

A user-fillable linear shaped charge (10), comprising an elongate body (15) and a liner (30), in which the charge further comprises a cavity (50) adjacent at least part of the liner for receiving explosive material, the cavity comprising two elongate channels (50A, 50B) extending adjacent the liner, the body having a delivery opening (55) between the channels for receiving explosive material.

• F42B 33/06 - Dismantling fuzes, cartridges, projectiles, missiles, rockets, or bombs

Abstract

Container (10) is generally cylindrical except for a longitudinal concave groove (11) extending along its entire length. Upon explosion, the contour of this groove (11) results in a focussing effect on the wall material due to the oblique angle at which the expanding cylindrical detonation wave front impacts upon its inner wall. This produces the forging of a rough rod-like projectile (111) which, being coherent, maintains its velocity and consequently travels much further than the randomly shaped projectiles (101).
