METHOD FOR MANUFACTURE OF FRAGMENTATION AMMUNITION Russian patent published in 2005 - IPC

FIELD: military equipment, applicable for manufacture of fragmentation ammunition to salvo-fire jet-propelled systems.

SUBSTANCE: the claimed method includes production of a shell by deformation and welding, arrangement of finished fragments and fastening to the ammunition body. The shell is molded of plates until a polyhedron is obtained, mainly of a trapezoidal shape with rounded off ribs, and after welding the polyhedron is deformed to a cylindrical shape by grooving, for example, in rolls with localization of deformations in three points, and a multiple, for example two-operation inner grooving, expansion with a decrease of deformation within 1 to 5 per cent, then the shell is placed in a mould, finished fragments are filled in and cast by thermoplastic material, for example, high-density polyethylene, and radial reduction in thickness is simultaneously performed over the entire outer surface, in separate symmetrical sections, for example, at least two, in the plastic area of deformation, and on the rest surface - in the flexible area, at a pressure of 60 to 80 kg/sq.cm during 44 to 46s.

EFFECT: enhanced efficiency of combat use of the ammunition by producing of an irregular stressed state in the shell of the set of finished fragments.
