Abstract
A liner for an explosive shaped charge is formed from a mixture of powdered metals into three or more conical sections wherein the axial height of the first two sections is 30% to 70% of the total liner height. The first conical section may be formed to an included angle of about 20° to about 60°. The second conical section is formed to a greater included angle of about 30° to about 70°. The third conical section is formed to a density less than that of the first and second section and to an included angle that is preferably greater than the first section and equal to or less than the second section.
Claims20
A shaped charge liner comprising at least three axially aligned, substantially frusto-conical sections formed by a mixture of compacted powdered metal, said sections having respective inner and outer substantially frusto-conical surfaces whereby inner and outer frusto-conical surfaces of a first section fairly transition into respective inner and outer frusto-conical surfaces of a second section and respective inner and outer frusto-conical surfaces of a second section fairly transition into inner and outer frusto-conical surfaces of a third section, a second conical angle respective to the inner frustoconical surface of said second section being greater than a first conical angle respective to the inner frusto-conical surface of said first section and a third conical angle respective to the inner frustoconical surface of said third section being less than said second conical angle but greater than said first conical angle.
A shaped charge assembly comprising a charge of highly explosive material that is intimately formed about a concave liner, said liner comprising a mixture of powdered metal that has been compacted to a consolidated configuration comprising at least three, axially aligned, substantially frusto-conical sections, said sections having respective inner and outer substantially frustoconical surfaces whereby inner and outer frusto-conical surfaces of a first section fairly transition into respective inner and outer frusto-conical surfaces of a second section and inner and outer frusto-conical surfaces of said second cone section fairly transition into respective inner and outer frusto-conical surfaces of a third section, a second conical angle respective to the inner frusto-conical surface of said second section being greater than a first conical angle respective to the inner frusto-conical surface of said first section and a third conical angle respective to the inner frustoconical surface of said third section being less than said second conical angle but greater than said first conical angle.
