UNDERBARREL GRENADE LAUNCHER AMMUNITION TO DESTROY UNMANNED AERIAL VEHICLES Russian patent published in 2023 - IPC F42B12/02 F41H13/00 

FIELD: military technology.

SUBSTANCE: invention relates to the field of military technology, in particular to ammunition for grenade launchers, grenade launchers designed for remote destruction or capture of low-flying unmanned aerial vehicles. Ammunition, made in the form of a grenade, contains a warhead and ammunition body. On the outer side surface of the body of the ammunition there is a leading belt and an annular groove, in which a mechanical distance switch is located. The warhead of the ammunition - grenade consists of a two-segment fairing (6) and a two-segment steel cup (7) with pins. The inner surface of the two-segment steel cup (7) is covered with a protective gasket (8), inside which a net (9) is laid with striking elements (10) attached to its corners. A wad (12) is located behind the two-segment steel cup (7). The body of the ammunition - grenade consists of a cylindrical steel cup (11), which plays the role of a combustion chamber and a guide for firing a two-segment steel cup (7) with a network (9) and striking elements (10). In a cylindrical steel cup (11) in the space behind the wad (12) there is a powder charge (13). The wad (12) is designed to prevent the breakthrough of powder gases between the wall of the cylindrical steel cup (11) and the two-segment steel cup (7). Behind the wad (12) and powder charge (13) there is a mechanical distance switch, consisting of front (25) and rear (19) fixed parts made of aluminum, an aluminum adjusting ring (20), three powder retarders (21), three gas generating powder charges (23), three steel balls (24), acting as valves for shutting off powder gases in the cylindrical part of the body, a bolt (17), a washer (26) with holes for transmitting a flame beam, a nut (18), connecting screws that regulate compression force of the adjusting ring, and screws (22) for laying gas-generating powder charges (23) and balls (24) into the channels of the front (25) fixed part, rubber ring (27) for tight connection of a cylindrical steel cup (11) with a mechanical distance switch . Behind the mechanical distance switch there is a transfer charge (16) and the bottom of the grenade (15), in which the propellant charge (14) of the underbarrel grenade launcher grenade is installed.

EFFECT: creation of a device with a large amount of internal space occupied by the net, which increases the area of the striking plane after shooting the net on the trajectory, due to which firing errors are leveled.
