The aim of the invention is to reduce friction losses and reduce radial deformation of the projectile with the leading part of the rolling elements. The proposed device contains a barrel 1 with breech 2, a shutter 4, a charging chamber 3. The leading part 5 of the barrel 1 is formed by grooves 6 in the form of gas transfer channels, fields 7 grooves and a longitudinal groove 7 made in each field. When firing the rolling body 9, the leading network of the projectile 10 moves along the grooves 7 without sliding friction, and the powder gases passed through the rifling put pressure on the walls of the projectile 10, reducing the radial deformation of the shells from the internal pressure of the equipment.

The well-known grenade launcher GP-25 [Material from the Internet], mounted under the barrel of a Kalashnikov assault rifle of all modifications, calibres 5.45 mm and 7.62 mm. A grenade launcher is charged with a shot from the muzzle of the barrel. The shot must be inserted into the barrel all the way to the end of the breech. In this case, the shot in the barrel is fixed with a special lock, which, in turn, is connected with a transmission lever that locks the trigger in such a way that when the shot is not completely sent out, firing becomes impossible. The open-type mechanical sight was used on the grenade launcher, which allows for targeted shooting at ranges from 100 to 400 m. The sight is located to the left of the machine’s aiming line. Combat rate of 4-5 rds / min. The disadvantage of the described known technical solutions are insignificant rate of fire and range.

Known automatic firearms [No. 2077011, IPC ⁶ , F41A 1/00 F41A 3/00, 1997.04.10], selected as the closest analogue. It is intended for use mainly in aircraft and anti-aircraft machine guns and cannons.

The inventive: to increase the rate of fire and the initial velocity of the projectile in an automatic firearm containing a barrel, a receiver, a sliding shutter with a gas channel from the charging chamber to the front end of the shutter, two feed mechanisms separately for shells and charges and an automatic drive, the latter is made with a gas outlet in the side wall of the barrel, with a gas cylinder and a gas piston associated with the shutter. The charging chamber is formed in the receiver with a charging window in the rear wall of the camera. The shutter is made of two interconnected parts, the front of which is located in front of the charging chamber with the possibility of sending a projectile into the barrel, and the rear of the front of the shutter is placed in the charging chamber with the possibility of longitudinal movement in it. The gas-conducting channel is formed as an axial nozzle in the front of the shutter, and the back of the shutter is located behind the charging chamber with the possibility of charging the charge into the chamber. The disadvantage of the invention is the complexity of the design, as well as the low rate of fire.

Known live cartridge for weapons [No. 97101350, IPC ⁶ , F42B 5/18, 1999.01.10], connected in series through a sleeve into one unit - a bullet, a powder charge, a means of ignition, a piston for firing a weapon in the air, inside the bouncer and reactive charges with a means of ignition. Explosion of the expelling charge in the projectile, without destroying its wall, throws the projectile along the barrel of the weapon to a certain range, at the same time ignition and combustion of the reactive charge, destruction of the tube of the nose diffuser through which air (water) enters the cavity to contact direct-flow reactive charge, charges converted into working gas (steam), which through the nozzle holes in the cavity of the projectile creates draft to the projectile and rotates the projectile due to the resistance of the spiral grooves in the cavity of the projectile around it and straight flight. The disadvantage of the invention is the complexity and bulkiness of the structure, due to which the speed and range are reduced.

The objective of the present invention is to increase the speed and range of fire, as well as simplifying the design.

The objective of the invention is solved by the proposed firearms, containing a barrel with a gas outlet on the side wall, with a gas cylinder and a gas piston, in which the barrel is made of two detachable parts connected to each other by a thread and a sleeve, and also contains a sleeve-bracket for mounting parts of the barrel , a ratchet wrench with a lock for twisting and unscrewing the barrel parts, a handle, a pusher, a pusher rod, a U-shaped bracket for clamping a projectile, an electric current battery to create an ignition spark, a trigger, a silencer, including a housing, a glass hermetically integrated in the barrel bore, a valve switch, a cylinder in which a piston, a rod and a return spring are placed, an electric rechargeable battery and an optical sight.

The problem is also solved by the proposed firearm for a firearm, which is a sleeve in which a refractory plastic bullet is placed, made with a groove for repelling a reactive charge, an ignition device and a lead hemisphere, and a reactive charge (mini rocket) containing a housing in which the camera is placed for ignition, a shank, a pressure indicator, a sleeve-starter, a perforated baffle for the exit of a flame of combustion of gunpowder, a jet engine and a jet charge retainer. The essence of the invention lies in the fact that due to the pressure of air and gas generated as a result of the burning of gunpowder in the liner, the plastic refractory bullet pneumatically, without touching the warhead, exerts pressure on the pressure indicator in the rear part of the mini-rocket, the plastic bullet plays the role of a piston pusher, which initiates the means of ignition in a mini-rocket, ignition of solid jet fuel and high-speed release of the jet charge. The high rate of fire and the range of fire of a firearm is ensured by summing the pressures exerted on a reactive charge by compressed air and the resulting combustion gases of the fuels.

The invention is confirmed by illustrations: Figure 1 - firearms. Figure 2 - cartridge. Figure 3 - mini-rocket.

Firearms (Figure 1) contains a barrel consisting of two parts: the front part 1, made with an internal socket for installing a mini-rocket, and the rear part 2, connected to each other by a threaded head 3, a sleeve-bracket 4, 5 for mounting barrel parts, ratchet wrench with lock 6 for twisting and unscrewing barrel parts, pusher rod 7, 8, cam follower 9, U-shaped bracket 10, handle with clamping head 11 for holding the chuck, electric current battery 12, electric wire 13 , electrical contacts 14, start button ku 15, trigger 16, hole 17, where the muffler valve switch 18 is sealed, a cup with contacts 19, relay 20, gas and flame outlet 21, piston rod 22, return spring 23, cylinder 24, piston 25, battery 26, contacts 27, an electric wire 28, a silencer body 29, a hole for supplying compressed air 30, an optical sight 31. A projectile for the proposed firearm is a cartridge and a mini-rocket.

The cartridge (Figure 2) contains a series-connected sleeve 32 with a powder charge, a refractory plastic bullet 33, a lead hemisphere 34, and electrical contacts 35 for igniting the powder made with a shaped groove. Mini-rocket (Figure 3) includes a housing consisting of a tail portion 36 with a chamber for gunpowder and a pressure indicator 37, a sleeve-starter 38, a perforated baffle 39 for transmitting fire, and a front part 40 with rocket fuel.

Firearms work as follows.

The front part 1 of the barrel is opened with a ratchet wrench 6, a mini-rocket is inserted into the barrel’s inner sleeve 38, clamped with a ratchet wrench, into the rear part 2 of the barrel, the handle with the clamping head 11 is pushed into the hole, the cartridge is inserted, the handle is moved upward , in the initial position, as well as using the U-shaped bracket 10, the cartridge is clamped tightly to prevent gas leakage. Through the hole with a check valve 30 in the rear of the barrel 2, compressed air is supplied into the space between the cartridge and the mini-rocket. By pressing the trigger 16 on the button 15 on the handle provide an electric spark with electrical contacts 35 and ignition of the powder in the combustion chamber of the cartridge case, the gas pressure drives a plastic bullet 33 with a lead hemisphere 34, designed for ballast. A plastic bullet pneumatically acts on the pressure indicator 37, while the compressed air in the barrel space does not allow the plastic bullet to come in contact with the mini-rocket, and it ignites the powder in the combustion chamber of the tail section 36 of the mini-rocket during flight. The flame through the perforated baffle 39 ignites solid rocket fuel in front of the mini-rocket 40, at the moment of rocket fuel ignition the tail section is reset. Between the sleeve-starter 38 and the wall of the barrel 1 there is a gap provided for the expansion of the sleeve-starter. Compressed air and gases from the combustion of fuel under high pressure press on the walls of the starter shell, expand the walls and at the same time push out the mini-rocket, while there is no deformation of the rocket charge. The gas pressure in the front of the barrel 1 between the mini-rocket and the plastic bullet presses on the muffler valve switch 18, which closes the contacts 19 in the glass, the pulling relay 20 is triggered, actuates the stem 22 with the piston 25, opens the hole 21 in the barrel, from where the muffler sucks gases and flames. The return of the piston to its original closed position of the hole is carried out using a return spring 23 located in the glass 24.

Firearms have a simple and sociable design, but at the same time they have a high rate of fire and projectile range.
