Abstract:

A shaped charge device having a cylindrical housing, an explosive charge with a cavity at one end, a fuze, booster, a multimaterial vertically layered liner having a hemispherical, semi-hemispherical, arcuate or conical shape with a number of segments of materials, each segment in contact with the explosive charge and the cavity, each segment oriented normal, parallel or oblique to the charge axis. The detonating of the explosive charge causes the liner to form a jet of a plurality of the segments. A method of manufacture is also disclosed wherein the liners made in the vertical manner avoid mixing or interaction between dissimilar materials undergoing the jetting action. Vertically layered liners provide excellent material flow and liner collapse diagnostics.
