Description

FIELD OF TECHNOLOGY

The invention relates to weapons, namely to automatic weapon-free weapons, in particular to weapons using the energy of the explosion of a mixture of gas, flammable liquid or other mixture in internal combustion chambers as a bullet propulsion device and can be used in all types of automatic weapons.

PREVIOUS TECHNOLOGY

The well-known "Automatic barrelless weapon system" (RU 2122170, IPC Classes - F41A 9/28, F41A 5/00, F41C 3/14, Published: 11/20/1998, Author - Tsvetkov S.A.), which includes a barrel, a bolt, bolt frame with gas piston, return mechanism and receiver. A distinctive feature of the system is the presence of a revolving drum in it with several chambers and blades on its surface and a tube for removing unburned particles of a propellant charge of ammunition. The camora, which is in the upper position, has the ability to perform the function of a chamber. The output tube of unburned particles of the propellant charge is located in front of the receiver with the possibility of combining with the front of the chamber of the turret drum when sending the ammunition into this chamber. The axis of the drum is the gas piston rod. Due to the presence of several chambers of the revolving drum, one of which is involved in the shot, while the others are cooled, and the enhanced ventilation provided by the blades of the revolving drum, the author believes, this eliminates the risk of self-ignition of shellless ammunition.

Disadvantages:

- use only cartridgeless cartridge.

- a complex trigger mechanism.

- there is no connection between the trigger and the trigger

Known patent "Cartridge-free automatic weapons" (RU 2578466, IPC Classes - F41C 3/00: 03/27/2016, Author - Rogulchenko AM), which contains a barrel, a box with a gas channel, predstole, receiver, shutter wedge, chamber shutter, wedge socket, powder cartridge and bullet clip. Bullets and gunpowder are loaded into the weapon separately in different parts of the weapon. Bullets are loaded from the bullet cage in the forehead, from where they then move to the barrel. Gunpowder is loaded from the powder cartridge into the powder receiving chamber, from where it then moves to the chamber, where the powder is combusted, from where the powder gases enter the barrel through the gas-conducting piston of the chamber shutter, where they fire the bullet. The ability to use various ammunition in weapons is achieved.

Disadvantages:

- the use of a volumetric and heavy cartridge for gunpowder

- design complexity

CHALLENGES

The invention is the creation of an automatic weapon-free system without marked drawbacks with a reusable bullet engine sufficient to produce 500 shots, replacing gunpowder with a more efficient, compact flammable mixture, minimizing soot in the barrel, reducing the weight and length of the machine, reducing recoil, bringing portable ammunition to 720 bullets without increasing the total weight of the soldier’s equipment.

SPECIFIED TASK

This task is achieved by the fact that instead of gunpowder, the weapon uses gas, a highly flammable liquid, or another mixture (hereinafter gas), placed under pressure of more than 15 atmospheres in a cylinder. The gas entering through the dispenser is mixed with air in the mixing tube and is fed under pressure to the upper combustion chamber through the combined openings in the chamber and the tube. Therefore, a cylinder with compressed gas, for example, a volume of 100 ml, when mixing gas with air in a proportion of 1:20 is enough to produce more than 500 shots.

The use of a gas mixture instead of gunpowder significantly reduces soot in the barrel and eliminates the remains of gunpowder.

The cameras are made in the form of elongated cylinders combined into a drum. The cross section of the internal combustion chambers is possible from round to trapezoidal. The bullets enter the machine’s bracket vertically and are inserted into the chamber when the drum moves to the barrel by pushing the camera nozzle onto the tail of the bullet. When the drum is rotated around its own axis and its longitudinal movement, the bullet of the upper chamber is sent to the barrel of the machine. The use of several internal combustion chambers in turn during the firing process, a chamber purge system after being shot with compressed air, and also supplying the mixture to only one upper chamber allows cooling the chamber ready for firing, including by rotating the drum, which eliminates arbitrary and premature ignition of the mixture .

The original layout of the machine, the absence of a striking mechanism, the use of the magazine as a stock, and the placement of only part of the bullet in the barrel chamber can significantly reduce the weight of the machine and its length.

The recoil during firing is reduced by the use of elongated exhaust gas outlet openings at the end of the gas pipe, which, as the piston approaches the muzzle, increases the size of the holes and slows the piston stroke, the direction of the powder gases in the gas pipe and the piston with the rod moving toward the muzzle of the barrel, and the use of a spring-loaded drum and a weighted magazine-butt.

The increase in portable ammunition by several times without increasing the total weight of the equipment is achieved by transferring only bullets that are 2-3 times lighter than the cartridge, as well as by using a multi-purpose magazine of increased capacity made in the form of a box, inside of which are clips with bullets. The store performs the function of a stock, and in the manufacture of a store’s box made of composite bulletproof fabrics or materials, it also has the function of armor plates on body armor.

When 8 spare stores are transported on the fighter’s body in the form of armored plates, the transportable ammunition is increased to 72 0 bullets, and the weight of the armor is reduced due to the use of “boxed” armor, the top layer of which significantly reduces the kinetic force of the bullet due to amortization, as well as the increased armor protection due clips and ammunition

SUMMARY OF THE INVENTION

The automatic weapon-free weapon, arranged according to the bullpup scheme, contains a barrel 5 with an opening 33 connecting the barrel channel with a gas pipe 12, a receiver in the form of a cylinder 2 turning into a rectangular box 7, several combustion chambers 2 6 combined into a drum 3, a trigger the mechanism 9, the piston 23 of the mixing tube 4 5 for preparing and supplying the mixture to the upper combustion chamber 26 and supplying compressed air through the tube 14 for purging the chambers after a shot connected by the rod 24 with the piston 34 of the gas tube 12, the cylinder 18 with compressed gas ohm, the ignition mechanism consisting of a piezoelectric element 28 and candles 25, a spare ignition system consisting of a battery 35 and a capacitor 36, a gas exhaust mechanism with a gas pipe 12 and a piston 34, in which gases are directed towards the muzzle end, the return mechanism of the drum 3 in the form of a spring 39 .

Bullets go into the bracket 27 of the machine vertically from the magazine 55 and are inserted into the chamber 2 6 when the drum 3 moves towards the muzzle by mounting the nozzle of the chamber 2 6 on the tail of the bullet. When rotating the drum 3 around its own axis and its longitudinal movement, the bullet of the upper chamber is sent to the barrel 5 of the machine.

The compressed gas cylinder 18 has a valve in the form of a needle 21, needle spring 4 0 and a nozzle 42. When the piston 23 presses on the needle 21, it is recessed into the nozzle 42, forming a gap between the needle 21 and the inner walls of the nozzle 42, through which the compressed gas enters into dispenser 22.

The piston 23 is rigidly connected by the rod 24 to the piston 34 of the gas tube 12. When the piston 34 moves under the influence of the "powder" gases towards the muzzle end, the piston 23 pulls the dispenser 22 by a distance sufficient for the dispenser 22 to close the opening 44 of the mixing tube 45 with the dispenser 22 and the needle 21 under the influence of the spring 40 at this time closes the gaps with the nozzle 42 stopping the flow of gas into the dispenser 22. Fixation of the dispenser 22, when it is pulled by the piston 23, is done by the antennae 54 of the needle 21. Moreover, between the walls of the figured hole in the back wall of the dispenser 22 and gaps are formed on the outer walls of the nozzle 42 through which air enters the dispenser 22 through the openings 41. An additional supercharger of air into the mixing tube 45 is the drum 3 when moving it back. The piston 23, moving towards the muzzle end, creates a vacuum in the mixing tube 45, thereby drawing gas into the tube 45 together with air mixing them.

When the piston 23 is moved by the mainspring 31 towards the cylinder 18, the dispenser 22 returns to its original position by the pressure of the gas mixture in the tube 45, closing the hole in its front wall with the needle 21. In this case, the piston 23 creates pressure in the mixing tube 45 and through the combined holes 43, 44 of the tube 45 and the upper internal combustion chamber 26 drives the gas mixture into the combustion chamber 26, compressing it to several atmospheres and in the final stage closes the hole 44.

At this moment, the hook 30 of the rod 24 strikes the piezoelectric element 28, which leads to the generation of energy and arson of the mixture in the upper chamber 2 6 with a spark between the electrode of the candle 25 and the wall of the chamber 26. The spark is produced only in the upper chamber 26 due to the fact that one the contact of the piezoelectric element 28 is closed to the drum casing 3, and the second contact 46 is attached to the upper frame 4 of the cylindrical receiver 2 and comes into contact with the electrode of the candle 25 when the bullet is in the barrel 5 and the machine is ready to fire. A shot is taking place.

Powder gases push the piston 34 of the gas tube 12, and with it the hook 30 towards the muzzle end. Not reaching the hole 33, the powder gases close the contact 32 of the relay 19 and the locking mechanism 20 opens, releasing the drum 3. The remaining powder gases shift the drum 3 to the leftmost position.

The shutter 6 is inserted into the machine through the figured window 17 of the receiver 7 and is fixed by the rod 24, which is the axis of the shutter 6.

When the shutter 6 is pulled back, it closes the contact 47 of the relay 19 and opens the locking mechanism 20, then acts on the drum 3 and takes it to the leftmost position by compressing the return spring 39. By releasing the shutter 6, we actuate the return spring 39, which pushes the drum 3 forward and he nozzle the lower chamber 26 is mounted on the rear of the bullet, fixing it in the nozzle of the camera. When the shutter 6 is pulled forward, it moves the hook 30 of the rod 24 together with the stem 24 and the pistons 23 and 34 to the extreme right position until the hook 30 is locked with a hook whispered 38. The shock spring 29 prevents the shutter 6 from moving together with the stem 24.

The gas pipe 12 is attached to the barrel 5 of the machine due to the tube of the hole 33, semicircle 13, and is fixed by the trigger box 9.

The back cap 1 fixes the gas bottle 18 and the magazine 55 in the machine.

The movement of the drum 3 back is carried out by powder gases, and forward by a return spring 39.

DRUM

The drum 3 is a few cylindrical cylinders 26 combined into a drum 3 around the tube-axis 48. The drum 3 freely rotates on this axis, and also moves along the axis in the longitudinal direction. The cameras 26 are located along the axis of the drum 3, and their nozzles have a diameter that allows you to sit on the tail of the bullet. The tube-axis 48 protrudes on one side of the drum 3 and on the protruding part there are curly grooves 49, which mates with the latch 50 and due to which the drum 3 moves along the axis and rotates.

LAUNCHING MECHANISM

It is located according to the bullpup scheme and consists of a housing 9 with hooks 10 for the projections 11 of the barrel 5, a profile 51 for fastening to the handle 8 of the machine, a security bracket 52 of the trigger 15, axles 53, sear 38, fuse 16, hook 15, oval 37 .

When you press the tail of the trigger 15, the oval 37 raises the front end of the sear 38 up, thereby lowering the rear end of the sear 38 down, leading it out of the hook 30 of the rod 24. The trigger 9 is fixed to the machine due to the hooks 10 of the protrusions 11 of the barrel 5.

FUSE

It is located on the outside of the machine, but at both ends it goes inside the machine, where the front end enters the trigger box 9 and mates with the sear 38, and the rear through the slot of the receiver 7 mates with the hook 30 of the rod 24, restricting the movement of the rod 24 and pistons 23, 34 in such a position that the piston 23 of the tube is not in contact with the needle 21.

The fuse has a minimum of three positions:

1) 1st position, when the sear 38 and the rod 24 are blocked together with the pistons 23 and 34.

2) the second position, when the left end of the fuse 16 falls down and releases the hook 30 of the rod 24. In this case, the right end of the fuse 16 releases the sear 38 so that it is sufficient to fix the hook 30 of the rod 24 and release it for firing. And while holding the trigger 15, the sear 38 lowers and does not come into contact with the hook of the rod, which leads to the continuous production of shots.

3) the 3rd position when the sear 38 is not limited by the fuse 16 and when you press the trigger 15, it acts on the oval 37, removing the sear 38 from the hook 30, sufficient for firing a shot. With further action on the trigger 15 and moving it to the extreme left position, it disengages from the oval 37 and ceases to act on the sear 38, which returns to the contact position of the hook 30. Returning to its initial state, the trigger 15 raises the left edge of the oval 37 until the oval 37 ceases to mate with the radius part of the hook 15 is lowered and enters the hook with the working surface with its front part.

AUTOMATIC OPERATION PROCEDURE

The magazine 55 with its grooves 56 is inserted into the rectangular profile 57 of the receiver 2, 7 and is fastened to the machine and fixed on it against lateral rolling by entering the U-shaped rear part of the handle 8. The rear one holds the magazine 55 out of the grooves of the machine cover 1.

Bullets vertically enter the machine and are fixed in bracket 27 at the level of the nozzle of the lower chamber 26. To load the drum 3, the shutter 6 moves backward, closing the relay contact, freeing the drum from the locking mechanism, after which the drum 3 by the shutter 6 is moved to the extreme left position. From the extreme left position, the drum 3 due to the return spring 39 moves forward to the barrel 5 and the nozzle of the lower chamber 2 6 is mounted on the tail of the bullet and captures it. To insert a bullet into the barrel chamber 5 with 4 chambers in the drum, this operation must be done 3 times, so that the lower chamber 2 6 can be moved up by turning the drum 3 and send bullets into the nozzles of the next two chambers. In this case, the piston 23 drowns the needle 21 of the gas drum 18 and the gas fills the dispenser 22. By moving the shutter 6 forward to the muzzle, we compress the mainspring 31 and start the hook 30 of the rod 24 into the sear 38. With this action, the piston 23 is also moved forward. , as a result of which gas and air are drawn into the mixing tube 45. The machine is charged and ready to fire with the fuse 16 removed.

The present invention completely solves the technical problem posed by the creation of an automatic weapon-free weapon with a reusable bullet engine by replacing the gunpowder with compressed gas in a cylinder, which allows you to abandon the cartridge and have only bullets and a cylinder with compressed gas as ammunition. The described solution allows to reduce the weight and length of the machine, minimizes soot in the barrel, reduces recoil, and brings the portable ammunition to 720 bullets without increasing the total weight of the soldier’s equipment, and also enhances the fighter’s armor protection.
