Free form hemispherical shaped charge
First Claim
1. A hemispherical shaped charge comprising:
- a. a contoured liner having a greater thickness at the pole than at the equator, wherein said liner has an outside surface that is aspherical and an inside surface that is spherical;
b. a charge explosive;
c. a case; and
d. a detonator.

Abstract
A hemispherical shaped charge has been modified such that one side of the hemisphere is spherical and the other is aspherical allowing a wall thickness variation in the liner. A further modification is to use an elongated hemispherical shape. The liner has a thick wall at its pole and a thin wall at the equator with a continually decreasing wall thickness from the pole to the equator. The ratio of the wall thickness from the pole to the equator varies depending on liner material and HE shape. Hemispherical shaped charges have previously been limited to spherical shapes with no variations in wall thicknesses. By redesign of the basic liner thicknesses, the jet properties of coherence, stability, and mass distribution have been significantly improved.
