CUMULATIVE CHARGE (OPTIONS) Russian patent published in 2021 - IPC F42B1/02 F42B1/28 

FIELD: explosives.

SUBSTANCE: proposed invention relates to the field of explosion processing, weapons, and oil and gas production, namely, shaped charges. The variants of the shaped charge are presented. Shaped charges contain a body, a shaped metal lining, an initiator and a high explosive filling the space between the body and the lining. The metal cumulative lining is a frame - a conical funnel formed from intertwining square wire, and the weaving feature is such that some wires coincide with the forming funnels, while others intertwine them. The second embodiment of the shaped charge differs in that the blasting explosive is pressed unevenly - denser sections of the explosive are pressed along a helical line.

EFFECT: improved penetrating ability of the shaped charge by increased density and length of the shaped charge.
