Description

The invention relates to the field of firearms and can be used primarily in the creation of samples of artillery and small arms.

A known method of producing a shot of a firearm, which consists in the fact that first the ammunition, consisting of a powder charge and a projectile, is placed in the breech of the main barrel, part of which is located with a gap in the guide barrel, after which the main barrel is accelerated inside the guide barrel to the side muzzle of the main barrel, followed by ignition of the powder charge (see, for example, RF patent No. 2363908, IPC F41A 25/00 dated 12/20/2008).

There is also known a method for producing a shot of a firearm, which consists in the fact that before firing from a firearm, ammunition is placed, consisting of a powder charge and a projectile, into the breech of the main barrel, part of which is located with a gap in the guide barrel. The main barrel is accelerated inside the guide towards the muzzle of the main barrel, followed by ignition of the powder charge. At the same time, a gaseous medium under pressure is supplied into the gap between the barrels through the flow limiters with the formation of a gas-static layer in the gap, centering the main barrel in the guide, and preventing active friction between their surfaces, (see, for example, RF patent No. 2546364, IPC F41A 25 / 00 dated 06/18/2013), selected as a prototype.

The disadvantage of the method chosen as a prototype is a complex design for the acceleration of the main barrel inside the guide towards the muzzle of the main barrel, followed by ignition of the powder charge.

The technical result consists in the possibility of using a substance in a liquid state of aggregation, gas (s) for the production of a shot. Reducing the weight and size characteristics of weapons.

The technical result is achieved by supplying gas (s) or liquid for the initial acceleration of the bolt with the projectile body or moving the projectile body towards the area of low pressure, followed by a change in the direction of movement, as a result of the formation of excess pressure, towards the muzzle of the barrel, form areas of low pressure with the possibility of increasing the flow rate of the supplied fluid into the area of low pressure, with or without violation of the continuity of the liquid flow in the area of low pressure, gas (s) are supplied under pressure to the area of low pressure, followed by detonation of the vapor-gas mixture, the formation of excess pressure and the production of a shot, with or without partial compensation for the recoil force of caseless weapons.

Based on the foregoing, we can conclude that the proposed technical solution has a "novelty" and "inventive step".

The method of producing a shot from a caseless weapon is implemented as follows.

It is necessary to fill the liquid supply mechanism, for this, liquid is supplied from the reservoir 4 with liquid (see Fig. 1), which fills the liquid supply channel 13, the internal volumes of the nozzle 9, the cylinder 11 of the liquid supply mechanism. In this case, the plunger 8 moves towards the high pressure channel 10, blocking the high pressure channel 17 into the high pressure chamber 18. The shutter 6 is located in its original position, with one part placed in the high pressure chamber 18, the other part in the reduced pressure chamber 19. In this case, the channel 16 of the piston 6 blocks the nozzle 9. The projectile 5 is placed in the channel 16 of the shutter 6. From the high pressure tank 3, through the high pressure channel 10, gas (s) is supplied under high pressure to the gas distribution valve 7.

To carry out the shot, it is necessary (see Fig. 2) to open the high-pressure channel 10 by shifting the gas distribution valve 7 (the valve drive mechanism is not shown in the figure; the numbering is not assigned). Under high pressure, gas (s) are supplied to the cylinder 11 of the liquid supply mechanism acting on the piston 8. The piston 8 from the cylinder 11 of the liquid supply mechanism displaces the liquid into the channel 14 of the nozzle 9. In this case, the valve 12 of the liquid supply closes the channel 13 of the liquid supply. Through the valve 15 of the nozzle 9, the liquid is supplied into the volume formed by the walls of the channel 16 of the shutter 6 and the walls of the nozzle 9.

Further movement of the piston 8 (see Fig. 3) leads to the opening of the channel 17 for supplying high pressure to the high pressure chamber 18. Under high pressure, the gas(s) are fed into the high pressure chamber 18. As a result of the increase in pressure, in the high pressure chamber 18, the shutter 6 moves towards the muzzle of the barrel. When this happens, the pressure decreases in the reduced pressure chamber 19, as a result of an increase in the internal volume of this chamber. Through the gap between the walls of the channel 16 of the shutter 6 and the walls of the nozzle 9, the liquid is sucked into the reduced pressure chamber 19. At the same time, the shutter 6 carries the projectile 5 towards the muzzle of the barrel, giving the projectile 5 initial acceleration.

When the shutter 6 moves (see Fig. 5), towards the muzzle of the barrel 2, gases are displaced from the internal space of the housing 1, through the bore 2, into the atmosphere. When the shutter 6 moves, the pressure in the reduced pressure chamber 19 is significantly reduced. As a result, the rate of fluid outflow from the channel 16 of the shutter 6 into the reduced pressure chamber 19 increases. pressure 19. In this case, the shutter 6 opens the channel 20 connecting the high pressure chamber 18 with the cylinder 21 of the valve 7 gas distribution. As a result, the gas pressure increases in the channel 20 connecting the high-pressure chamber 18 with the cylinder 21 of the valve 7 of the gas distribution and in the cylinder 21 of the valve 7 of the gas distribution. Under the influence of high pressure gases, the valve 7 gas distribution moves in the cylinder 21 of the valve 7 gas distribution towards the opening 22 of the cylinder 21 of the valve 7 gas distribution. When this spool 7 valve blocks the channel 10 high pressure and displaces gases from the cylinder 21 of the spool 7 gas distribution, through the hole 22 of the cylinder 21 spool valve 7 gas distribution, into the atmosphere. The supply of gas(s), under high pressure, to the pressure chamber 18 is stopped.

When the shutter 6 moves (see Fig. 6), towards the muzzle of the barrel 2, the shutter 6 opens the low pressure chamber 19. Under high pressure, the gas (s) from the high pressure chamber 18 enters the low pressure chamber 19. A sharp increase in pressure , in the reduced pressure chamber 19, leads to the detonation of the gas-vapor mixture and the formation of excess pressure in the high pressure chamber 18, in the reduced pressure chamber 19, in the channel 16 of the shutter 6. In this case, under the influence of gas pressure, the valve 15 of the nozzle 9 closes. , significantly increases the speed of the shutter 6 and the projectile 5 in the direction of the muzzle of the barrel 2. In this case, the speed of the projectile 5 is higher than the speed of the shutter 6 due to the mass difference.

The projectile 5 (see Fig. 7) enters the bore 2. At the same time, the pressure increases in the volume formed by the internal space of the body 1, the cut of the barrel 2, the projectile 5 and the end of the shutter 6. As a result of the increase in pressure, the speed of the shutter 6 decreases.

When the bolt 6 moves (see Fig. 8), towards the muzzle of the barrel 2, the bolt 6 abuts against the barrel 2. In this case, the recoil force of the caseless weapon is partially compensated. The projectile 5 flies out of the bore 2. When this happens, the outflow of gases from the internal space of the body 1, through the bore 2, into the atmosphere. The shot has been fired.

The method for producing a shot from a caseless weapon is different in that the initial acceleration of the projectile body occurs as a result of the fluid pressure on the projectile body (see Fig. 2). In this case, the liquid additionally fills the volume formed by the bottom of the projectile 5 and the walls of the channel 16 of the shutter 6 and the walls of the nozzle 9, partially enters the chamber of reduced pressure 19. In this case, the initial acceleration of the projectile 5 occurs as a result of the liquid pressure on the projectile 5. Subsequently, the shutter 6 ( see Fig. 3) additionally informs the projectile 5, having the initial speed, acceleration.

The method for producing a shot from a caseless weapon is different in that the supply of liquid to the area of low pressure is carried out as a result of the pressure difference acting on the liquid. In this case, the liquid is supplied to the volume formed by the bottom of the projectile 5 and the walls of the channel 16 of the shutter 6 and the walls of the nozzle 9, partially enters the reduced pressure chamber 19.

The method for producing a shot from a caseless weapon is different in that when fired, there is no partial compensation for the recoil force of a caseless weapon. Depending on the performance of the caseless weapon (see Fig. 9), a projectile-piston 24 is placed in the body-barrel 23. The liquid is supplied through the nozzle 9 into the internal volume 25 of the projectile-piston 24, and the energy of the gas (s) directly affects the projectile -piston 24. In this case, the projectile-piston 24 moves towards the muzzle. When this happens, the pressure decreases in the reduced pressure chamber 19 and in the internal volume 25 of the projectile-piston 24. In this case, the liquid "boils". Further movement, in the housing-barrel 23, the projectile-piston 24 opens the channel 20 connecting the high pressure chamber 18 with the cylinder 21 of the spool 7 gas distribution. In this case, the supply of gas(s), under high pressure, to the pressure chamber 18 is stopped. With further movement, the projectile-piston 24 opens the reduced pressure chamber 19. Under high pressure, the gas (s) from the high pressure chamber 18 enters the reduced pressure chamber 19. A sharp increase in pressure in the reduced pressure chamber 19 leads to detonation of the vapor-gas mixture and the formation of excess pressure in the high pressure chamber 18, in the low pressure chamber 19 and in the internal volume 25 of the projectile-piston 24. Further movement in the body-barrel 23, the projectile-piston 24 does not engage with the body-barrel 23. This does not occur partial compensation for the recoil force of caseless weapons. The projectile-piston 24 flies out of the housing-barrel 23. When this occurs, the outflow of gases from the internal space of the housing-barrel 23 into the atmosphere. The shot has been fired.

The method for producing a shot from a caseless weapon is characterized in that the outflow of liquid into the area of reduced pressure is carried out without violating the continuity of the liquid flow due to the low speed of the liquid flow from the channel formed by the walls of the channel 16 of the shutter 6 and the walls of the nozzle 9 into the reduced pressure chamber 19, and as well as a slight decrease in pressure in the reduced pressure chamber 19.

The method for producing a shot from a caseless weapon is distinguished by the fact that the projectile, as a result of the pressure difference acting on the projectile, moves towards the area of low pressure with a subsequent change in the direction of movement, as a result of the formation of excess pressure, towards the muzzle of the barrel. As a result of a significant decrease in pressure in the reduced pressure chamber 19 (see Fig. 4), the projectile 5 is affected by a pressure difference, which leads to a decrease in the speed of the projectile 5, followed by a stop and the beginning of the movement of the projectile 5 towards the area of low pressure. When the shutter 6 moves (see Fig. 6), towards the muzzle of the barrel 2, the shutter 6 opens the reduced pressure chamber 19. Under high pressure, the gas(s) from the high pressure chambers 18 enter the reduced pressure chamber 19. A sharp increase pressure, in the chamber of reduced pressure 19, leads to the detonation of the vapor-gas mixture and the formation of excess pressure in the chamber of high pressure 18, in the chamber of reduced pressure 19. In this case, the speed of the projectile 5 decreases, followed by a stop and movement of the projectile 5 towards the muzzle of the barrel 2.

All of the above differences are the advantage and advantage of the proposed technical solution in comparison with the prototype.
