Description

The invention relates to ammunition, in particular to ammunition of unitary loading / unitary cartridges /, and can be used as ammunition for automatic small arms "revolving type", also having automatic loading and extraction of spent cartridges.

Known ammunition for unitary loading / Zhuk A.B. Handbook of Small Arms, Moscow: Military Publishing House, 1993, p.19, Fig. 15, pos. A, see image to “obsolete American cartridges inserted into the front drum” / containing a unitary cartridge sleeve for small arms ” revolving type, "charged and extracted through the muzzle hole of the next charging chamber.

The disadvantage of this device is the lack of a central bottom socket for the capsule, as well as the cylindrical shape of the sleeve, which makes it difficult to automatically load the drum magazine.

The unitary loading ammunition is known / the source is the same, see page 19, Fig. 15, pos. B /, which is the closest analogue in technical essence to the declared object, because it contains a sleeve, the breech of which / in this case is “hemispherical” / facilitates the automatic loading of the drum magazine of the small arms through the muzzle of its next charging chamber, also the sleeve of this unitary cartridge has a bottom central socket for the capsule element initiating the powder charge of the cartridge in this case, the so-called. "nipple type".

The disadvantage of this device is its inability for automatic small arms "revolver type", which use small-caliber / automatic / cartridges, for example a 5.45 / 39 mm cartridge with the possibility of obturation of powder gases between the barrel and the drum of the weapon, carried out by any element of the "internal equipment "cartridge.

The technical task is to adapt the small-caliber cartridge / automatic / to automatic small arms "revolver type".

The technical result is achieved in that the unitary loading ammunition is designed as a unitary cartridge for small arms, a "revolver type", charged and extracted through the muzzle hole of the next charging chamber of the drum magazine, contains a sleeve whose muzzle diameter is larger than its breech diameter, as well as the bottom of the sleeve has a central socket and other elements that provide ignition of the powder charge of the cartridge from the shock capsule and throwing a "bullet" or, "special" projectile, while there is "p hive sleeve ", which, when fired, moving in the cartridge case to the barrel of the weapon, obturates the powder gases, preventing their breakthrough, between the breech section of the barrel of the weapon and the muzzle section of the next charging chamber of the drum magazine, as well as between the walls of the" bullet sleeve "and surrounding its cartridge sleeve, as well as between the “bullet sleeve” itself and the bullet covered by it, located in the axial channel of the sleeve, which also centers the bullet along the longitudinal axis of the cartridge sleeve; in addition, a small-caliber bullet “borrowed” from a standard cartridge of 5.45 / 39 mm or a cartridge of 5.56 / 45 mm is equipped in a unitary cartridge; in addition, the case of the sleeve has the shape of a “cylinder” in its muzzle, and the shape of a “slightly expressed case with a truncated apex "in its breech, the bottom of the sleeve also has a central capsule nest with an anvil, and two" seed holes ", in addition, the" bullet sleeve "has a breech-like" funnel-shaped "end facing the charging chamber of the sleeve, as well as this sleeve fully open inside the indrical "part of the cartridge case, in addition, the" bullet sleeve "is made of aluminum alloy to reduce its weight, or the sleeve is made of steel alloy to increase its strength; in addition, there is an additional sealing washer, which is attached to the muzzle end of the “bullet sleeve” by means of “glue connection”, in addition, the small-caliber shell bullet of the cartridge is fixed inside the “axial channel” of the bullet sleeve according to the “tight fit” type, in addition, the “bullet sleeve” has several “annular grooves” on the axial outer surface that prevent the breakthrough of powder gases between the “bullet sleeve” itself and the cartridge sleeve enveloping it, also fixing the “bullet sleeve” together with the bullet covered by it inside the sleeve is carried out by “crimping” the metal sleeve of the cartridge, in the annular groove - “bullet sleeve”, in addition, there is an additional “cap-shutter” having a “dustproof” function, which is fixed in the muzzle hole of the axial channel of the “bullet sleeve”, In this case, this cap has a “beveled” muzzle end and is removed outside when fired through the bore through an insignificant amount of powder gases, overtaking a bullet going through the rifles of the gun barrel.

Distinctive features in the claimed combination show a new property - the possibility of obturation of powder gases between the breech end of the barrel and the muzzle end of the next charging chamber of the drum magazine of arms by means of a movable sleeve, obturating the "bullet sleeve", as an element of the "internal equipment" of a unitary cartridge, while this sleeve serves as an element that “centers” a small-caliber / automatic / bullet along the longitudinal axis of a larger diameter sleeve.

The technical result is ensured by the fact that the "bullet sleeve" is placed in the sleeve of the unitary cartridge, which is adapted for loading / and extraction / through the muzzle hole of the next charging chamber of the drum magazine. That allows you to create under such a cartridge, an automatic / "assault rifle" / as a weapon of a "revolving type" with a "carriage automation scheme", which has significant advantages over other automation schemes that are currently accepted for weapons of this class.

The invention is illustrated by drawings, where:

figure 1. Unitary loading ammunition / unitary cartridge / shown in frontal section, on the right side of the image there is an option with an additional sealing washer; figure 2. The operation of a unitary cartridge during firing is shown, in the upper part of the image a variant with an additional sealing washer is shown.

Ammunition unitary loading / unitary cartridge / contains a metal sleeve - 1 / Fig.1, 2 /; central bottom capsule nest - 2 with a “shock capsule” located in it; powder charge of the cartridge - 3; movable in the sleeve, obturating the "bullet sleeve" - 4, which has a breech-like "funnel" end face - 5, several "annular grooves" - 6, a small-caliber shell bullet - 7, for example, borrowed from a standard cartridge 5.45 / 39 mm; additional sealing washer - 8; "cap-shutter" - 9; the "anvil" of the sleeve - 10; two "seed holes" - 11. The weapon barrel is also shown - 12; charging chamber / drum magazine / - 13.

The unitary loading ammunition / unitary cartridge / works as follows: when fired, the “bullet sleeve” - 4, under the influence of powder gases pressing on the bottom of the sleeve, moves forward in the sleeve, obturating the powder gases, between the breech of the barrel and the muzzle of the next drum charging chamber magazine / 12, 13 /, as well as between the "pool sleeve" - 4 and the sleeve covering it, which is carried out through the "ring grooves" - 6, preventing the breakthrough of powder gases, as well as between the "inner walls" of the pool sleeve - 4 and coverage the bullet 7 she calls until the bullet passes into the barrel of the weapon - 12. In this case, the “bullet sleeve” 4 “centers” the small-caliber shell / machine gun / bullet 7 along the longitudinal axis of the cartridge case 1, which has a larger caliber. In this case, an option with an additional sealing / polymer / washer 8, located on the muzzle end of the "bullet sleeve". It is also possible option with an additional "cap-obturator" 9, placed in the channel "bullet sleeve" 4, and removed outward through the barrel channel through a small amount of powder gases / figure 2 - are shown by arrows /, which overtake the bullet 7, which is cut the barrel of the weapon 12. At the same time, the “cap-shutter” 9, having a “sloping” muzzle end at the exit from the barrel of the weapon, is shifted to the side of its flight path without creating a jamming pool 7.

The claimed unit-loading ammunition device can be used as a unitary cartridge for small arms of a “revolver type”, for example, a weapon / assault rifle / with an “gun mount” automation circuit, as well as automatic loading and extraction through the muzzle hole of another charging chamber drum shop.
