SHOT TO THE GRENADE LAUNCHER Russian patent published in 2022 - IPC F42B5/02 F42B30/04 

FIELD: ammunition.

SUBSTANCE: invention relates to ammunition, in particular to shots for grenade launchers. The shot for the grenade launcher contains a warhead of functional equipment, a liner, which includes a jet engine, consisting of a combustion chamber with a fuel stick and an igniter, and a bottom part commensurate with the barrel prechamber. The bottom part contains a combustion chamber equipped with outlet openings and equipped with a propelling powder charge and a central primer-igniter. A special feature is that the central primer-igniter through an axial throttling channel communicates through the igniter with the combustion chamber of the fuel checker of the jet engine, and the combustion chamber of the jet engine through at least one offset from the axis of the throttling channel is connected to the annular combustion chamber of the propellant charge placed at the bottom of the shank and separated from the primer-igniter. The inlet openings of the motor nozzles and the throttling channel have equal diameters and are closed by a common diaphragm.

EFFECT: improvement of the design of an active-reactive shot to the grenade launcher in order to synchronize the processes of the engine reaching the operating mode and ignition of the propellant charge, compensating for the spread in the time of the engine reaching the operating mode, stabilizing the intra-ballistic parameters of the shot and, thus, improving the accuracy indicators.
