Description

Description of the invention

The invention relates to the field of armaments, in particular, to automatic small arms, namely, to 2 automatic weapons of the Kalashnikov system.

The invention can be used to arm special units and paratroopers.

A known automatic weapon of the Kalashnikov system, which includes a barrel, a receiver, a receiver cover, a gas chamber, a gas tube with a receiver cover, a bolt frame with a gas piston and a bolt handle, a bolt with a striker, a return mechanism with a spring, a fire control handle, a forend, magazine, 70 magazine latch, stock, shock-trigger fuse, safety clip and sight /1/,

Among the disadvantages of the well-known automatic weapons of the Kalashnikov system is that the long length of the weapon limits the convenience in combat use, the fire control handle is located outside the center of mass of the weapon, which makes it difficult to aim fire with one hand. The well-known automatic weapon of the Kalashnikov system is made according to the classic layout scheme, that is, for ease of aiming, the butt is shifted below the longitudinal 12 obi of the barrel. With such a scheme, there is a shoulder between the fulcrum (shooter's shoulder) and the axis of the barrel, which contributes to the formation of a rotating moment at the time of the shot. Because the force of recoil and the force of counteraction equal to it do not act along the same line, a pair of forces is formed, which causes the weapon to deflect with the muzzle part of the muzzle. At the same time, the size of the deviation of the muzzle part of the barrel is greater, the greater the distance between the longitudinal axis of the barrel and the butt stop point.

The closest technical solution, both in substance and in terms of the result to be achieved, which was chosen as a prototype, is an automatic weapon of the Kalashnikov system, which contains a barrel and a receiver rigidly fastened together, a cover of the receiver, a gas chamber, a gas tube with barrel cover, bolt frame with gas piston and bolt handle, bolt with firing pin, recoil mechanism with spring, fire control handle, buttstock, magazine, magazine latch, buttstock, trigger mechanism with trigger, front and rear sear and trigger, safety , a protective bracket and a sight containing a front sight and a rear sight 121. "

The shortcomings of the well-known automatic weapon of the Kalashnikov system, which was chosen as a prototype, include the fact that the long length of the weapon limits the convenience in combat use, the fire control handle is located outside the center of mass of the weapon, which makes it difficult to aim fire with one hand. Known automatic weapons of the system

The Kalashnikov is made according to the classic layout scheme, i.e., for ease of aiming, the stock is shifted below the longitudinal axis of the barrel. With such a scheme, there is a shoulder between the fulcrum (shooter's shoulder) and the axis of the barrel, which contributes to the formation of a rotating moment at the time of the shot. Because the force of recoil and the force of counteraction equal to it do not act along the same line, a pair of forces is formed, which causes the weapon to deviate with the muzzle part of the upper part. At the same time, the size of the deviation of the muzzle part of the barrel is greater, the greater the distance between the longitudinal axis of the barrel and the butt stop point. Also among the disadvantages is the fact that an angle is formed between the direction of the axis of the barrel before the shot and its direction at the moment of departure of the bullet, which, in turn, leads to an increase in the scattering of bullets, especially when firing bursts.

The invention is based on the task of improving the tactical and technical characteristics of weapons by changing the design. "

At the same time, the mentioned front part of the buttplate 17 is connected to the rear part of the latch 16 of the magazine. both with a gap and without a gap (see Fig. 10). and?" Structurally, a fuse 30 is installed on the right side wall of the receiver 2 (see Fig. 10).

Automatic weapons of the Kalashnikov system are operated in this way.

The design of the weapon is pre-assembled. To do this, the barrel 1 with the gas chamber 4 and front sight 23 is fixed

Ge" on the receiver box 2. Next, structural elements of the shock-trigger mechanism are placed inside the receiver box 2 (trigger 18, front 19 and rear 20 whisperer and other details that are not shown in Fig. 1-11). The rod 27 of the trigger 21 is attached to the front 19 of the sear (see Fig. 11). To the lower part of their receiver 2, buttplate 17 and latch 16 of the magazine are attached. At the same time, the butt 17 is installed so that 5p the rear part of the butt 17 is located in the plane of the end part of the receiver 2, and the front and part of the butt 17 is in close proximity to the rear part of the latch 16 of the store (with

With a gap or without a gap). Fuse Z0 is installed on the right side wall of receiver 2 (see Fig. 10). A magazine 15 is inserted into the receiver of the magazine, which is structurally made on the lower surface of the receiver 2 (in front of the bolt 16 of the magazine). The gas tube 5 with the receiver cover 6 is installed. 11 and the return mechanism with a spring 12. After that, the inner cavity of the receiver 2 is closed with a cover 3. On top of the receiver

P boxes 2 set the rear sight 24 (see Fig. 10).

Next, technological operations are performed, during which a power platform 25 is attached to the front part of the receiver 2, which is structurally made of a box-type O-shaped cross-section, with a cutout in the lower part 28 for the passage of the trigger 21, and with technological holes 29 for attaching the handle fire control 13 (at the same time, the right side wall of the power platform 25 is technologically made lower in height than its left side wall, see Fig. 1-2).

At the same time, the trigger 21 is pre-fixed in the aforementioned cut-out 28 of the power platform 25.

The fire control handle 13 is fixed to the power platform 25 in front of the cutout 28 for the passage of the trigger 21 (using technological holes 29). The trigger 21 is closed with a protective bracket 22, which is fixed on the lower surface of the power platform 25 (using technological holes 29). Further to the trunk

1 (In the area of the gas chamber 4) fasten the specified power platform 25 with the above-mentioned elements of the weapon design fixed on it. After that, the free end of the trigger rod 27 is attached to the mentioned trigger 21 (see Fig. 11), and the fore-end 14 is attached to the front part of the power platform 25 (see Fig. 9).

At the final stage of assembling the weapon, a shock-absorbing pad 26 is attached to the rear end part of the butt 17 (see Fig. 10). At the same time, the mentioned shock-absorbing pad 26 is fixed so as to close the end parts of the buttplate 17 and the receiver 2.

Automatic weapons of the Kalashnikov system are operated in this way.

Previously, the magazine 15 is equipped with cartridges (position 31, see Fig. 10) and the equipped magazine 7/0 5 is inserted into the receiver of the magazine (which is structurally made on the lower surface of the receiver 2 in front of the latch 16 of the magazine). Next, the weapon is picked up, while the shooter's right hand is on the fire control handle 13, and the left hand is on the butt 14. Holding the weapon by the butt 14 with the left hand, the right hand affects the ZO fuse and sets it in the position necessary for firing, for example , for firing single shots or bursts. Then, with the right hand, they affect the shutter handle 9 (reloading handle /5) and move the shutter frame 7 with the gas piston 8 to the rearmost position. At the same time, the trigger 18 of the shock-trigger mechanism is raised and the spring 12 of the return mechanism is compressed, and the front 19 and rear 20 whisperers become a combat platoon.

When the bolt handle 9 is released, the bolt frame 7 with the bolt 10 with the striker 11 placed in it will begin to move to the side of the chamber under the action of the spring 12 of the return mechanism (position 32, see Fig. 11). When the shutter 10 passes over the magazine 15, the shutter 10 pulls out the upper cartridge 31 from the magazine 15 and sends it into the chamber 32. The weapon is ready for firing.

The shooter aims the weapon at the target by connecting the front sight 23 with the slot of the rear sight 24.

To produce a shot, the shooter presses the trigger 21 with the index finger of the right hand. At the same time, the trigger 21 turns in the suspension assembly 33 and with the help of the rod 27 affects the front 19 of the Whisperer. The front 19 whisperer releases the trigger 18, which is released and strikes the striker 11. The striker 11 moves forward and impales the cartridge capsule 31. A shot is fired. When a shot is fired, part of the powder gases emerging in the bore of the barrel 1 behind the bullet is ejected through the hole (which is made in the wall of the barrel 1) into the gas chamber 4 and affects the gas piston 8 of the shutter frame 7. At the same time, the gas piston 8 with the shutter frame 7 is sharply thrown back (moving inside the gas tube 5). с зо Moving back, the bolt frame 7 with the front bevel of the shaped cutout (in Fig. 1-11 - not shown) turns the bolt 10 around the longitudinal axis Я and brings out its combat protrusions (in Fig. 1-11 - not shown) through the combat stops of the receiver 2 (not shown in fig. 1-11). The bolt 10 is unlocked and the bore of the barrel 1 is opened. When moving back, the bolt 10 pulls the sleeve out of the chamber 32 and throws it out.

The shutter frame 7 when moving back compresses the return spring 12 and cocks the trigger 18. At the moment when the recoil force becomes equal to the compression force of the return spring 12, the backward movement of the shutter frame 7 will stop. In the forward position, the shutter frame 7 is rotated under the action of the mentioned return spring 12 of the return mechanism.

At the same time, the shutter 10 pulls out the next upper cartridge 31 from the magazine 15 and sends it to the chamber 32.

At the same time, the shutter 10, turning to the right, closes the cartridge 31 in the chamber 32 (closes the bore of the barrel 1).

To create a shot, you must press the trigger 21 again (if the fuse 30, which at the same time "

Performs the functions of a switch of types of fire, is in a position for conducting fire with single shots). z c The back 20 whisperer (single fire) will be engaged, the trigger 18 (according to the above) will release and strike the firing pin 11, the next shot will take place. ;" If the fuse 30, which simultaneously performs the functions of a fire type switch, is in the position for conducting automatic fire (in turns), then in this case, the shutter frame 7, when moving forward, brings out the front trigger 19 from under the trigger platoon of the trigger 18. At the same time, automatic firing would continue until the trigger 21 is pulled.

Increasing the effectiveness of the Kalashnikov automatic weapon system, which is claimed, in comparison with the prototype, is achieved by changing the design by adding an intermediate power platform, placing it in front of the receiver, fixing the mentioned power platform on the barrel, 5r moving the fire control handle in front of the store and placing it on the power platform, moving the bow about forward with respect to the power platform and fixing it on the front part of the specified power platform in the area

Ge of the gas chamber, transferring the trigger to the area of the power platform and placing it in the cutout on the mentioned power platform, connecting the trigger with the help of an additional pull with the front sear, placing the butt on the lower surface of the receiver and connecting the end part of the mentioned butt with the plane of the The end part of the receiver, placement on the end parts of the receiver and the butt of the shock-absorbing pad. Increasing the effectiveness of the Kalashnikov automatic weapons, which

P" is claimed, in comparison with the prototype, is also achieved due to the fact that the length of the weapon is reduced, the fire control handle is moved to the area of the center of mass of the weapon, which ensures the convenience of holding the weapon and firing with one hand, and the resulting scheme of the weapon with a "direct" butt leads to the fact that the longitudinal axis of the barrel is as close as possible to the fulcrum, and all moving parts - the shutter and the return mechanism - also move along this line. Increasing the effectiveness of the automatic weapon system

The proposed Kalashnikov, in comparison with the prototype, is achieved due to the fact that, thanks to the obtained scheme of the weapon, there are no prerequisites for the displacement of the muzzle part of the barrel when firing, and the scattering of bullets is minimal. 65 SOURCES OF INFORMATION 1.
