CAPSULATED CASE FOR RIFLED AND SMOOTH-BORE CARTRIDGES FOR COMBINED GUNS WITH REPLACEABLE PAIRS OF SHAFTS Russian patent published in 2016 - IPC F42B5/26 F42C19/10 

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to production of capsulated shells to threaded and smooth-bore cartridges and can be used for production of said cartridges. Capsulated shell includes metal cap with pressed into it with ignition compound of impact action coated with sealing membrane, and inserted inside it a three-lobed domed anvil, pressed by its top to sealing membrane, and by its base to annular protrusion or a capsule seat of shell, or metal shell, located in capsule seat of shell around metal cap. All geometrical dimensions and mark of metal of metal cap, mark, mass of priming composition of impact action and configuration of press-fitting of priming composition of impact action are same as for rifled cartridge, and for smooth-bore cartridge with both metal and plastic or paper shell. Design of capsulated plastic or paper shell comprises metal shell of detonating cap in form of thin-walled cylinder with flange at end of cylinder with bending cylinder walls at other end face by 180° inside with a radius of 0.1-0.15 mm more than half thickness of wall, and cylinder length is selected so that three-wall dome anvil with its base is located in collar of cylinder end.

EFFECT: technical result consists in creation of a unification design of capsulated shell for rifled and smooth-bore guns for combined guns with replaceable pairs of shafts with same primer initiation sensitivity to impact gun striker.
