Description

The invention relates to the field of armament, namely to automatic firearms.

Known automatic small arms (AK-74), taken as a prototype, including a barrel interconnected with a muzzle brake, a means for placing cartridges interconnected with a magazine box, a piston-pusher, a bolt, a handle (see the newspaper "Komsomolskaya Pravda. 23.02. - 03/01/2012, p. 15).

Of the main disadvantages, the following can be noted:

- during the movement of the piston-pusher with the bolt back and during an abrupt stop, the barrel throws up;

- the center of gravity of a known weapon is below the axis of the barrel; when recoiling, the weapon rotates around its axis. The axis of rotation is the center of gravity, as a result, the barrel throws up;

- the handle is below the axis of the barrel, when kicked, the machine throws up.

These shortcomings reduce accuracy and accuracy of fire. The task to which the invention is directed is to improve the operational properties of firearms and expand the arsenal of structural schemes used in the design. Another objective is to increase the efficiency of automatic firearms by absorbing recoil energy, reducing barrel oscillations, increasing accuracy of fire and increasing lethal force.

To solve this problem, an automatic firearm, including a barrel interconnected with a muzzle brake, a means for placing cartridges interconnected with a magazine box, a piston-pusher, a bolt, a handle, according to the invention, the weapon is made smooth-bore, with the possibility of providing a center of gravity on the axis of the barrel, this means for placing cartridges is made in the form of two horizontally mounted on both sides of the store box stores made with the possibility of alternately spending thrones, the muzzle brake is made in the form of a rocket-reactive muzzle brake, which is located at a distance from the edge of the barrel and is made in the form of backward inclined openings in the barrel body with a profile expanding from the barrel channel, the piston-pusher and the shutter are made in such a way that their center symmetry is the axis of the barrel, the handle is located at the end of the weapon, while the weapon is additionally equipped with a gas-turbine gyroscopic stabilizer of the barrel, located on the barrel.

A gas-turbine gyroscopic barrel stabilizer includes slotted openings made in the barrel and a cylinder with gas-turbine-type blades mounted on the barrel, with the blades being placed opposite the slotted holes and rotatable around the barrel.

The implementation of the means for placing cartridges in the form of two horizontally mounted on two sides of the store box stores, made with the possibility of alternate expenditure of cartridges, eliminates the fluctuation of the weapon in any direction, which increases the accuracy of fire.

The implementation of the muzzle brake in the form of a rocket-reactive muzzle brake, which is located at a distance from the edge of the barrel and made in the form of backward inclined openings in the barrel body with a profile expanding from the barrel channel, allows to create an anti-recoil effect, i.e. recoil along the axis of the barrel is significantly reduced, which increases the stability of the barrel and, as a result, increases the accuracy of fire.

The execution of the piston-pusher and the shutter in such a way that their center of symmetry is the axis of the barrel also increases the stability of the barrel, which increases the accuracy of fire.

Placing the handle at the end of the weapon contributes to the stability of the weapon, which increases the accuracy of fire.

The supply of the inventive weapons gas turbine gyroscopic stabilizer barrel, located at the end of the barrel, also provides additional stability to the barrel, which increases the accuracy of fire.

Running the barrel smooth increases the speed of the bullet, which increases the effectiveness of small arms.

The claimed invention is illustrated by drawings.

The inventive automatic firearms are structurally 100% executed in accordance with Newton’s Law 3 - every action is counteracted equal in magnitude and oppositely directed. Automatic firearms (figure 1, 2) is configured to provide a center of gravity on the axis of the barrel and includes a barrel 1 interconnected with a muzzle brake 2, a piston pusher 3, a shutter 4, a handle, two magazines, a gas turbine gyroscopic stabilizer 5 of the barrel 1, located on the barrel 1. The muzzle brake 2 is made in the form of a reactive muzzle brake, which is located at a distance of about 100 mm from the edge 6 of the barrel 1 and is made in the form of holes 7 in the body of the barrel 1 with a profile inclined backward from the edge of the barrel at a 45 ° angle, expanding I’m from the bore, with a diameter of 4 mm in the wall of the barrel and 8 mm at the outlet, the length of the holes 10-15 mm. The gas-turbine gyroscopic stabilizer 5 of the barrel 1 includes slotted openings 8 made in the barrel and a cylinder 9 with gas turbine blades 10 and is worn on the barrel 1 with blades 10 opposite the slotted holes 8, rotatable around the barrel 1. The edge of the barrel 6 is conical to protect the firing from powder gases. The piston-pusher 3 and the shutter 4 are made in such a way that the axis of the barrel 11 is their center of symmetry. Magazines are horizontally mounted on both sides of the magazine box 12 with the possibility of alternating expenditure of cartridges, which keeps the mass of magazines at any time almost the same. In the lid of the magazine box 12 above the bottom of the cartridges, a semicircular part with a lever in the middle is movably fixed, which moves by interacting with another movable lever located on the rod 13 of the piston-pusher 3. The lever has two positions: to the right, to the left, with fixation due to the spring, located on the bar. A semicircular part switches stores for alternate use of cartridges. Namely, moving, for example, to the left, a semicircular part fills the bottom of the cartridge of the left magazine, so the shutter can pick up the cartridge from the right magazine, while the semicircular part moves to the right, fills the cartridge of the bottom of the right magazine, the shutter takes the cartridge out of the left magazine, etc. d. The handle is located at the end of the weapon. The handle has two positions: parallel to the shops - the machine does not shoot (this position is used mainly for transportation) and in the vertical position comes into contact with the trigger. In addition, on the left side, under the thumb, a small lever is made to switch the shooting mode: short burst - two shots and long bursts.

Dismantling the machine. When the stopper is inserted, the handle is removed to the side from the store box 12, then the cover of the store box 12 is removed. At the front of the store box 12, remove the bar 14 - barrel lock 1, then forward the barrel 1, piston-pusher 3, cylinder 15 and shutter 4. Assembly is carried out in the reverse order.

The weapon works under the influence of powder gases.

After the shot, the bullet 16 moves along the barrel 1.

Powder gases through the holes 17 in the thickening of the barrel 1 press on the ring 18 of the piston-pusher 3, which goes freely to the middle of the cylinder 15, where the holes are made 19. Further, the ring 18 works as a compressor piston, compresses the air to the required pressure. Compressed air plays the same role as a spring in an AK type machine. While the bullet 16 flies 100 mm after the jet muzzle brake 2, through eight holes 7, the cross-sectional area of which is six times the area of the hole of the barrel 1, through holes 7, which are essentially nozzles of the rocket engine, more than half of the high-pressure powder gases will fly out, which gives a push of the weapon forward by 5-10 mm. Next, a bullet 16 and the remaining gases fly out, which produces recoil, but first the kinetic energy of the weapon is quenched forward, the remaining energy from the bullet 16 and gases will produce a return that is several times less than the usual recoil from AK-type assault rifles.

Moving through the holes 8 of the gyroscopic stabilizer 5, the powder gases hit the blades 10 of the type of gas turbine, which untwist the cylinder 9, made, for example, of steel, which acts as a gyroscope. Gyroscopic stabilizer 5 eliminates the smallest vibrations of barrel 1. So, with a barrel length of 500 mm with a deviation of the barrel edge of 1 mm and a distance of 50 m from the target, the bullet deviation will be 100 mm, 2 mm - 200 mm, etc. The installation of a gyroscopic stabilizer 5 increases the accuracy of fire, the resulting weighting at the end of the barrel also contributes to the accuracy of fire.

The barrel 1 is made smooth, which increases the acceleration speed of the bullet 16 and increases the lethal force of the weapon. Figure 3 presents an example of the execution of the barrel, the inner surface of which contains the guiding protrusions 20 of a triangular section, which serve as threaded grooves.

Thus, the claimed invention allows to increase the effectiveness of automatic firearms, while absorbing recoil energy, damping the vibrations of the weapon, simplifies and lightens the design, increases the reliability and accuracy of automatic firing, increases the lethal force.

The invention of a reactive bullet relates to the field of weapons, namely to ammunition for smoothbore small arms.

Known bullet, including the head part and a jet engine (patent RU 21078863. 02.16.1996, publ. 03/27/1998).

The disadvantage is the complexity of the design and manufacture. The problem to which the invention is directed is to improve the operational properties of ammunition and expand the arsenal of structural schemes used in the design. Another objective is to simplify the design.

To solve the problem in a jet pool, including a head part and a jet engine containing a nozzle, fuel, according to the invention, solid rocket fuel is used as fuel placed in the cylindrical part of the rocket engine with the formation of a cone in contact with the cavity of the jet engine, expanding to a nozzle located in the rear of the jet engine.

The invention is illustrated in the drawing.

Figure 4 shows schematically a reactive bullet for a smooth-bore automatic firearm.

A reactive bullet 16 contains a lead part 21 made of lead with a brass shell 22, a jet engine 23. The jet engine 23 includes a housing 24, in the cylindrical part of which solid rocket fuel 25 is placed with the formation of a surface 27 in contact with the cavity 26 of the jet engine 23 in the form cone (to increase the area of sunbathing), expanding to the nozzle 28. The nozzle 28 is placed in the rear of the jet engine 23.

After ignition in the cartridge of gunpowder from the capsule, the gases formed, having a high temperature and pressure, carry out an ejection effect on the reactive bullet 16 in the direction of the muzzle of the barrel 1. Bullet 16, translating, leaves the cavity of the sleeve into the barrel 1, gaining speed. At the same time, solid rocket fuel 25 will ignite from the breakthrough of the powder gases through the nozzle 28, during the combustion of which a large amount of gaseous working fluid is released, which flows out of the nozzle 28 and creates rocket thrust. Bullet 16 acquires additional acceleration, while increasing the kinetic energy of the bullet 16.

The inventive bullet has improved performance, a simpler design, high initial speed and the ability to further increase the flight speed after departure from the barrel, giving it stable stabilization in the barrel and on the flight path.
