Abstract:
A projectile with lateral bulging effect for combating armored targets, said projectile comprising an outer cylindrical body; a hollow cylindrical tubularly-shaped casing encompassing said outer body at least partially or entirely, said casing fragmenting into predetermined body portions; said casing having a constant uniform diameter and wall thickness along the axial extent thereof and being constituted of a material selected from the group of materials consisting of; tungsten heavy metal; tungsten hardened metal; depleted uranium and; high strength steel; and a mass consisting of a bulging medium filling the interior of said hollow cylindrical tubularly-shaped casing and constituting an effective active charge, said casing and said bulging medium having a leading end terminating in an impact surface extending perpendicularly of the longitudinal axis of said casing for impacting a target in surface contact, said bulging medium being selected from the group of materials consisting of glass-fiber reinforced plastic, polyethylene, nylon, aluminum, copper, lead, tantalum, synthetic resin-containing compressed wood and composites constituted of plastics and metal excluding iron and steel and being of a density and strength which is lower than the density and strength of the material of the casing, wherein the material of said casing upon impacting a target is ballistically more effective than the material of the effective active charge, such that upon the projectile impacting against the target, the bulging medium is axially retarded and thereby compressed within a compression zone proximate said leading end of the casing and so as to laterally bulge and impart a radially outward deflection to at least the leading end of the casing penetrating into the target.
