CUMULATIVE HIGH-EXPLOSIVE COMBAT CHARGING COMPARTMENT OF UNIVERSAL SMALL-SIZED TORPEDO Russian patent published in 2021 - IPC F42B12/02 F42B12/10 F42B3/08 

FIELD: military technology.

SUBSTANCE: invention relates to the field of military technology and can be used in combat charging compartments (CCC) universal small-sized torpedoes (UST), designed to destroy surface and underwater targets, and attacking enemy torpedoes. CCC UST has a combined explosive charge, which consists of three coaxially located explosive compositions, a conical shaped-charge lining and an inert lens. The central charge is made of a pressed blasting compound with a mass of 3 to 10 percent of the total mass of charges, the middle charge is made of a cast explosive composition, a charge with a mass of 22 to 40 percent of the total mass of charges, the peripheral charge is made of a high-explosive explosive composition with a mass of 50 up to 75 percent of the total mass of charges. Casting high-explosive composition contains 16-24% of octogene, 29-32% of aluminum powder, 32-37% of ammonium perchlorate and 15-18% of a mixture of LD-70 with an acrylic copolymer. In the front part of the hull of the combat charging compartment, a conical shaped-charge lining with a cone opening angle of 65-75 degrees, with a thickness of 0.02-0.035 of the lining diameter, is fixed. From the side of the central charge, the lining has a coaxial cylindrical protrusion with a length and diameter of 0.025-0.05 times the diameter of the lining, and on the opposite side has a coaxial spherical recess with a radius of 0.025-0.05 times the diameter of the lining. The central charge is located coaxially to the facing and is distant from it at a distance of 0.25-0.4 from the diameter of the central charge. From the side of the facing, an inert lens in the form of a truncated cone adjoins the central charge with a base diameter equal to the central charge diameter, 0.15-0.25 height from the central charge diameter, with a cone opening angle along the generatrix of 100-120 degrees. The medium charge adjoins the cladding and fills the body along its entire length. The peripheral charge fills the space between the case and the medium charge.

EFFECT: combination of a sufficiently high level of high-explosive and cumulative action of CCC during an underwater explosion.
