FIELD: weapons and ammunition. SUBSTANCE: automatic gun comprises drum-type breech block and drum-type magazine. Drum magazine is arranged ahead of drum breech block. EFFECT: compact design. 1 dwg
The invention relates to small arms and compactness superior automatic weapons, made by the scheme of the bullpup. Known machine with a drum shutter, comprising: a barrel, drum, extractor, striking mechanism, a pusher and a store of ammunition, smarna "Weapon" No. 1, 1997, p.34, 35, in which the cartridges from the magazine type "horn" is served in the cylinder chambers. Extending the functionality of the prototype described in the patent RU №2247295 C1. In order to reduce the length of the device while maintaining its technical characteristics machine with a drum shutter drum magazine contains: barrel, drum bolt, the extractor sleeve, a percussion mechanism and a drum shop, established before the drum shutter and is made of several tubular shops, set in a circle with the axis of rotation parallel to the axis of the drum shutter. The device is illustrated schematically, where: 1 - barrel, 2 - drum shutter, 3 - reel store, made coaxial with the barrel. Machine with a drum shutter drum magazine works as follows: spring-loaded ammo from the tube store, part of the drum shop 3, sequentially fill the drum drum shutter. In the chamber, combined with the barrel 1, is initiated by a shot through the shock mechanism, and in the firing chamber, compatible with the seal with the extractor, the cartridge case is ejected. If there are no cartridges in a tubular drum shop shop 3 turns one position in the drum drum shutter 2 continue to go the rounds of the next tubular outlet 3. It should be noted that the drum drum shutter in order to facilitate the extraction of shells can be made conical, that is, decreasing in cross section toward the rear of the chamber, and the sleeve may have a "rim" in the front. Also the back of the chamber may be muted, but to have the hole for the shock mechanism. Drum shop from the back side may be provided with a rotating shutter with a hole, the diameter of which is equal to the inner diameter of the tube drum shop. The shutter is designed for fixation of rounds in the tube drum shop. The axis of the drum magazine can be located both above and below the axis of the drum, depending on the layout of the weapons. The number of barrels, chambers in the shutter and the number of tubular drum stores in the store is not specified. Machine with a drum shutter drum magazine containing barrel, drum bolt, the extractor sleeve and the percussion mechanism, characterized in that the drum magazine is installed before the drum shutter and is made in the form of a tubular shops have been fitted the x in a circle with the axis of rotation, parallel to the axis of the drum shutter
