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).
Claims12
-14. (canceled)
An explosive charge comprising a tubular container, said container comprising four walls, said walls being equally radially spaced, each of said walls comprising a concave longitudinal flute, said concave longitudinal flutes extending along substantially the entire length of said container and upon detonation of the charge, said flutes produce coherent linear projectiles, said linear projectiles providing a cutting effect applied in four equally spaced directions.
A linear explosively formed projectile charge for producing projectiles, the charge comprising an elongate casing having a compartment portion containing explosive material and having four equally radially spaced longitudinal rounded grooves which extend along substantially the entire length of said elongate casing and, upon detonation of said explosive material, each of said grooves produce coherent linear projectiles in which no jet is formed in said coherent linear projectiles.
A tubular charge comprising a container comprising four concave longitudinal flutes which extend along substantially the entire length of said container, each of the concave longitudinal flutes having wall material and upon detonation, each of the flutes form a coherent linear projectile in which about 90% of the wall material in each of said flutes constitutes each said linear projectile.
