Abstract

A method of operation of automation of riffle-gun arms in one cycle of operation of which there is provided the cartridge seating to the cartridge-chamber by means of the breech-mechanism, with clocking the channel of the barrel, shoot implementation, unlocking the channel of the barrel and extraction of the shot shell by the back motion of the breech-mechanism; at that the barrel due to interaction through the rifling with the bullet (missile) moving in it gets rotary motion round its long axis with direction opposite to the direction of rotation of the bullet (missile), with performing one complete turn in one cycle and with continuous rotation to the same side at shooting bursts, this is used directly for locking and unlocking the channel of the barrel. To simplify the structure of the arms, unlocking of the barrel takes place before the bullet (missile) leaves the barrel, and the excess pressure of powder gases in the barrel is used to give to the breech-mechanism through the shell bottom of pulse needed for extraction of the shell and for compression of back spring under action of which after that seating of the next cartridge to the cartridge chamber is performed; at that thebarrel mechanically interacts with the sear of the plunger mechanism with provision of its switch-off for implementation of impact by the pin (hammer) over the primer of the cartridge after locking the barrel only.

Description

Description of the invention

The useful model refers to weapons, in particular, to rifled automatic small-armor guns and 2 operations of its automation.

The highest requirements for reducing the weight of the weapon and increasing its rate of fire are placed on aviation guns and aviation machine guns. Therefore, in recent decades, the most developed from this point of view was precisely the aviation small-arms and cannon weapons.

The greatest increase in the rate of fire of aircraft weapons was achieved by increasing the number of barrels from 70 to 4-6 and combining them into a rotating block with alternate firing from each barrel, which ensured the combination of actions in the automatics of all barrels and smooth feeding of the cartridge belt during firing. At the same time, it was possible to overcome 1-3 misfires in a row due to the kinetic moment of the barrel block during their rotation |11.

In addition, weapons with a rotating block of barrels have another advantage - stabilization of the axis of rotation of the block in space during firing due to its gyroscopic properties.

However, the increase in the number of barrels led to a significant complication and, most importantly, an increase in the weight of the weapon.

All this led to the fact that recently single-barreled aviation guns began to appear again (11.

However, the advantages of multi-barreled weapons (automatic elimination of misfires, stabilization of the firing direction) made it necessary to develop a single-barreled weapon with the same advantages. It turned out to be possible to implement in weapons with a rotating barrel.

As the analysis shows, the operation of the automation of modern classic (single-barreled) weapons is based on the law of conservation of the amount of movement of the system of the bullet (projectile) and other parts of the weapon (bolt, barrel, receiver, other parts, their combinations, and the entire weapon as a whole). But in |2| described another method of operation of rifled small arms automatics, which is based on the law of conservation of the momentum of the system of rotating along the grooves of the barrel of the bullet (projectile) and the barrel itself, which has the ability to rotate freely around its 29 longitudinal axis. in

In one cycle of operation of the aforementioned automatics, the cartridge is fed into the barrel chamber using the bolt, the barrel is closed, the shot is fired, the barrel is unlocked, and the spent casing is extracted by the return movement of the bolt. A distinctive feature of the method is that the barrel, due to the interaction through the grooves with the bullet (projectile) moving in it, acquires a rotational movement around its longitudinal axis, in the reverse direction of rotation of the bullet (projectile), making one complete revolution in one cycle , which is used by Ha") directly to close and open the barrel, and through a mechanical converter - for reciprocating shutter movement. When shooting in bursts, the barrel rotates in one and the same direction continuously. This method is an analogue for the proposed method of operation of automatic weapons with a rotating "I barrel. 3o The above-described method of automatic operation is quite suitable for artillery weapons, machine guns, automatic weapons and - pistols, but requires the presence of a mechanical converter in order to use the rotary movement of the barrel for the reciprocating movement of the shutter. At the same time, in some models of small-arms and cannon weapons, it is possible to do with a simpler method of automatic operation, which does not require such a converter, which at the same time "leads to a certain reduction in the weight of the weapon. With 50 For the implementation of the above, a method of operation of the automatics of small-arms weapons is proposed, during one cycle of which the cartridge is fed into the chamber of the barrel by means of a shutter,

From" locking the barrel, firing, unlocking the barrel and extracting the fired casing by the reverse movement of the bolt, and the barrel, due to the interaction through the grooves with the bullet (projectile) moving in it, acquires a rotational movement around its longitudinal axis, opposite to the direction of rotation of the bullet (projectile), 45 making one complete revolution in one cycle and rotating continuously in the same direction when firing - a sequence used directly to lock and unlock the barrel, which differs in that "" unlocking the barrel takes place before departure bullet (projectile) from the barrel, and the residual pressure of the powder gases in the barrel is used to give the bolt through the bottom of the cartridge case the impulse necessary to extract the cartridge case and to compress the return spring, under the action of which the next cartridge is subsequently sent to the o 20 chamber, while the barrel mechanically interacts with the sear of the hammer-trigger mechanism, ensuring its exclusion for striking the hammer kom (trigger) on the capsule of the cartridge in the chamber only after closing the barrel.

In the above method of operation of the automation, the advantages of the analogue are preserved - increased stabilization of the axis of the weapon during firing due to gyroscopic properties and elimination of misfires due to the kinetic moment of the rotating barrel - but the design of the weapon is simplified. c The proposed method of operation of the automation of a single-barreled rifled weapon with a target can be implemented in the same way as the analog |2) is implemented in its constructive implementation |Z.

A useful model was created in my spare time using open sources of information.
