Description

The invention relates to the field of firearms and can be used mainly 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 through the use of a method for producing a shot from an automatic caseless weapon, which uses:

- the energy of the gas(s) for the implementation of: liquid supply, initial acceleration of the projectile, formation of a low-pressure area in the low-pressure chamber with the possibility of increasing the fluid outflow rate, into the low-pressure area, with a violation of the continuity of the liquid flow in the low-pressure zone, displacement of gases from the chamber high pressure, followed by pressure equalization in the high pressure chamber and automatic shutdown of the gas supply(s);

- the inertia of the movement of the shutter for the implementation of the supply of gas (s) under pressure into the chamber of reduced pressure;

- the energy of the gas(s) for the detonation of the gas-vapor mixture;

- pressure energy of the propelling gas for locking the bore, firing a shot, while accumulating the propellant gas;

- the energy of the propelling gas for the return of moving parts to their original position, the displacement of gases from the high-pressure chamber and the low-pressure chamber, the creation of pressure in the low-pressure chamber with the possibility of outflow of gases from this chamber, while the shutter speed decreases, the gas outflow rate increases , through the gap between the shutter channel and the nozzle from the reduced pressure chamber, leads to a decrease in pressure in the gap and the possibility of supplying liquid.

With the further movement of the parts, to their original position under the influence of the energy of the propelling gas, the pressure in the high pressure chamber is released. In this case, the speed of the shutter movement decreases, followed by the rotation of the shutter along the axis of rotation of the shutter and its stop. In this case, the projectile is fed to the line of the bore. At the same time, the supply of gas (s) is automatically resumed, the energy of which (s) is used to carry out, in the automatic mode of firing, to re-execute a shot, in a single mode of firing, to set the shutter to the position of readiness for a second shot. In this case, it is possible to carry out a blank shot both in a single firing mode and in an automatic firing mode.

The technical result is achieved through the use of a device containing: a body, a barrel with a barrel protrusion, a cocking mechanism pusher, a shutter stop, a shutter with a shutter protrusion, a shutter spool and a shutter piston, a guide stop, a pusher of the descent mechanism with a pusher support, a pusher lever and a spring of the pusher lever , a gas distribution mechanism with a valve of the channel of the gas distribution mechanism, a valve spring, a spool of the gas distribution mechanism, a spool spring and a cylinder of the spool of the gas distribution mechanism, a high pressure reservoir, a high pressure chamber, a reduced pressure chamber, an injector, a liquid supply chamber, a liquid reservoir.

In an automatic caseless weapon, it is possible to use a shutter 6 for firing a shot, characterized in that in the channel 27 of the shutter 6 (see Fig. 5) there is a nozzle having a subcritical section of the nozzle 41 of the channel 27 of the shutter 6, a critical section of the nozzle 42 of the channel 27 of the shutter 6 and a supercritical section nozzles 43 of the channel 27 of the shutter 6, with the possibility of converting the internal energy of the gases into the kinetic energy of the gases of directional movement at the moment of the outflow of gases through the shutter channel.

In an automatic caseless weapon, it is possible to use a shutter 6 (see Fig. 4) for firing a shot, characterized in that the shutter 6 is made with a broadening 26 of the shutter 6, the diameter of which is greater than the diameter of the piston 8 of the shutter 6, while after automatically stopping the supply of gas (s), the movement of the shutter, for the implementation of the supply of gas (s) under pressure into the chamber of reduced pressure, is carried out under the influence of the pressure energy of the gas (s).

In an automatic caseless weapon, it is possible to use a shutter 6 (see Fig. 4) for firing a shot, characterized in that the shutter 6 is made with a broadening 26 of the shutter 6, the diameter of which is less than the diameter of the piston 8 of the shutter 6, while after automatically stopping the supply of gas (s), the movement of the shutter, for the supply of gas (s) under pressure to the chamber of reduced pressure, is carried out with a slowdown in the direction of the barrel under the influence of the pressure energy of the gas (s).

In an automatic caseless weapon, for a shot, it is possible to carry out a blank shot both in a single firing mode and in an automatic firing mode.

The method of firing a shot from an automatic caseless weapon is implemented as follows.

It is necessary for the arrow (see Fig. 1) to move the shutter 6 to its original position with the pusher 15 of the cocking mechanism. In this case, the pusher 15 of the cocking mechanism engages with the protrusion 9 of the shutter 6. The shutter 6 moves in the opposite direction from the barrel 2. In this case (see Fig. 10A), the protrusion 9 of the shutter 6 engages tangentially with the guide stop 46 of the protrusion 9 of the shutter 6. The guide stop 46 of the protrusion 9 of the shutter 6 rotates the shutter 6 relative to the axis of rotation of the shutter 6. In this case, the protrusion 9 of the shutter 6 stands on the stop line 20 of the protrusion 9 of the shutter 6. In this case, the pusher 15 of the cocking mechanism prevents the protrusion 9 of the shutter 6 from moving off the stop line 20 protrusion 9 of the shutter 6. The shutter 6 is in the safe position.

In this case, the pusher 15 of the cocking mechanism switches the fuse 16 of the fire selection mode to the fuse position. In this case, the fuse switch 16 of the fire selection mode blocks the pusher 15 of the cocking mechanism.

The groove 37 of the rammer 40 of the shutter 6 (see Fig. 1) is aligned with the window 55 of the projectile feeder. The projectile 5, under the influence of the elastic element of the store acting on the pusher (not shown in the figure, the numbering is not assigned), enters the groove 37 of the rammer 40 of the shutter 6.

After setting the shutter 6 in the safe position, 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 11. Through the liquid supply valve 12, the liquid supply chamber 13 is filled. From the chamber 13 of the liquid supply, the internal volume of the nozzle 10 is filled.

To produce a shot from an automatic caseless weapon, the energy of the gas (s) is used to supply the liquid, which is implemented as follows: By opening the high-pressure tank 3 (see Fig. 1), gas (s) is supplied at high pressure through the channel 22 of the gas supply (s ) (see Fig. 2), through the spool 23 of the gas distribution mechanism, into the chamber 25 of high pressure, into the channel 24 for supplying gas (s) to the diaphragm 14. In this case, the diaphragm 14, under the influence of pressure, displaces the liquid into the nozzle 10 from the chamber 13 liquid supply. In this case, the liquid supply valve 12 closes the liquid supply channel 11. Through the nozzle 10, the liquid is supplied to the channel 27 of the shutter 6.

When the pressure in the high-pressure chamber 25 increases, the spool 7 of the shutter 6 moves towards the barrel 2 and abuts against the broadening 26 of the shutter 6. In this case, the shutter 6, moving towards the barrel 2, the protrusion 9 of the shutter 6 engages with the stop 20 of the protrusion 9 of the shutter 6.

To fire the arrow, it is necessary (see Fig. 2) to move the pusher 15 of the cocking mechanism to the extreme position from the shutter 6. In this case, the pusher 15 of the cocking mechanism switches the switch-fuse 16 of the fire selection mode to the single fire position. In this case, the pusher 15 of the cocking mechanism (see Fig. 10B) does not prevent the protrusion 9 of the shutter 6 from moving off the stop line 20 of the protrusion 9 of the shutter 6.

The shooter, by pressing the pusher 21 of the trigger mechanism, through the trigger (numbering not assigned) displaces the latch 17 in the channel 18 of the latch 17, compressing the spring 19 of the latch 17. In this case, the pusher 21 of the trigger mechanism (see Fig. 10B) moves in the channel 48 of the pusher 21 of the mechanism descent. In this case, the support 49 of the pusher 21 (see Fig. 10B) in contact with the walls of the channel 48 of the pusher 21 of the descent mechanism performs the function of a bearing and prevents the pusher 21 of the descent mechanism from being pressed against the channel 48 of the pusher 21 of the descent mechanism. The lever 50 of the pusher 21 (see Fig. 10B) engages with the protrusion 9 of the bolt 6. The spring 51 of the lever 50 of the pusher 21 presses the pusher lever 50 towards the trigger. In this case, the protrusion 9 of the shutter 6 is displaced relative to the stop line 20 of the protrusion 9 of the shutter 6. In this case, the shutter 6 rotates (see Fig. 3) relative to the axis of rotation of the shutter 6. The groove 37 of the rammer 40 of the shutter 6 is displaced relative to the window 55 of the projectile feeder. The protrusion 9 of the shutter 6 (see Fig. 3 and Fig. 10G) disengages from the stop 20 of the protrusion 9 of the shutter 6 and stands on the line of the channel 38 of the pusher 15 and (see Fig. 8) the groove 47 of the protrusion 9 of the shutter 6. In this case the lever 50 of the pusher 21 (see Fig. 10D) with the protrusion 52 of the lever 50 of the pusher 21 under the stop 20 engages with the stop 20. The spool 7 of the shutter 6 engaged with the shutter 6, under the influence of the energy of the gas (s) performs the initial acceleration of the projectile 5 .

When moving the shutter 6 (see Fig. 3), in the direction of the barrel 2, in the chamber 28 reduced pressure is significantly reduced pressure. The decrease in pressure occurs due to an increase in the volume formed by the walls of the chamber 28 of reduced pressure, the walls of the piston 8 of the gate 6 and the walls of the nozzle 10. Through the gap between the channel 27 of the gate 6 and the nozzle 10, as a result of the movement of the gate 6 towards the barrel 2 and a significant decrease in pressure in the chamber 28 reduced pressure, there is an increase in the rate of flow of liquid into the chamber 28 reduced pressure. In this case, there is a violation of the continuity of the liquid flow in the zone of low pressure and the formation of a vapor-gas mixture in the chamber 28 of low pressure. In the chamber 28 of reduced pressure, also as a result of a decrease in pressure, liquid is supplied through the nozzle 10 to form a vapor-gas mixture.

The spool 7 of the shutter 6 (see Fig. 2) moves towards the barrel 2 displaces gases from the high-pressure chamber 25, through the narrowing 29 of the chamber 25 in which the rammer 40 of the shutter 6 is located. Subsequently (see Fig. 3) broadening 26 of the shutter 6 enters the constriction 29 of the chamber 25 and locks the gases in the high pressure chamber 25. Further movement of the spool 7 of the valve 6 (see Fig. 4), towards the barrel 2, opens the window 57 for supplying pressure to the channel 30 of the gas distribution mechanism. The valve 31 of the channel 30, under the influence of gas pressure, compresses the spring 32 of the valve 31. This increases the pressure in the cylinder 33 of the spool 23. The spool 23 of the gas distribution mechanism begins to move towards the breather 35, compressing the spring 34 of the spool 23. At the same time, displacing gases through the breather 35 into atmosphere. Through the open channel 30 of the gas distribution mechanism, the pressures are equalized in the high-pressure chamber 25 in front of the spool 7 of the shutter 6 and behind the spool 7 of the shutter 6. When the shutter 6 moves towards the barrel 2, the groove 37 of the rammer 40 of the shutter 6 enters the protrusion 36 of the barrel 2.

The rammer 40 of the shutter 6 (see Fig. 4) displaces gases from the channel 39 of the rammer 40 of the shutter 6 into the bore 2. In this case, the projectile 5 tangentially engages with the protrusion 36 of the barrel 2. This obturates the channel 27 of the shutter 6 with the projectile 5 and partial overlap of the groove 37 of the rammer 40 of the bolt 6 with the projectile 5 and the protrusion 36 of the barrel 2.

When this broadening 26 of the shutter 6 displaces gases from the constriction 29 of the chamber 25 into the store.

The spool 23 of the gas distribution mechanism, under the influence of the pressure energy of the gas (s) moves and blocks the channel 22 of the gas supply (s). In this case, an automatic shutdown of the gas supply (s) occurs.

The shutter 6 continues to move by inertia towards the barrel 2 (see Fig. 4). When this is the supply of gas(s) under pressure in the chamber 28 reduced pressure. As a result of the exit of the piston 8 of the shutter 6 (see Fig. 5) from the chamber 28 of reduced pressure.

A sharp increase in pressure, as a result of the supply of gas (s) under pressure in the chamber 28 of reduced pressure, leads to the detonation of the gas-vapor mixture. The pressure increases in: the chamber 28 of reduced pressure, the chamber 25 of high pressure, the channel 24 of the gas supply (s) to the diaphragm 14, the channel 30 of the gas distribution mechanism, the cylinder 33 of the spool 23. This equalizes the pressures from the side of the channel 24 of the gas supply (s) to diaphragm 14 and the chamber 13 of the liquid supply. This equalizes the pressures in the chamber 25 of the high pressure in front of the spool 7 of the valve 6 and from the side of the chamber 28 of the reduced pressure. In this case, the valve 31 of the channel 30, under the influence of the elastic force of the spring 32 of the valve 31, begins to block the channel 30 of the gas distribution mechanism. The pressure energy of the projecting gas tightly presses the jammer 6 to the barrel 2. In this case, the channel 39 of the rammer 40 of the shutter 6 is closed by the rammer 40 of the shutter 6. The groove 37 of the rammer 40 of the shutter 6 is completely entered into the protrusion 36 of the barrel 2. In this case, the protrusion 9 of the shutter 6 does not touch the pusher 15 cocking mechanism. In this case, the valve 31 of the channel 30 (see Fig. 6) closes the channel 30 of the gas distribution mechanism, accumulating the pressure of the propelling gas in the volume formed by the walls of the widening 26 of the shutter 6, the high pressure chamber 25, the spool 7 of the shutter 6, the channel 30 of the gas distribution mechanism and the cylinder 33 of the spool 23 .

Throwing gas enters (see Fig. 6), through the channel 27 of the shutter 6, to the projectile 5. The pressure from the bottom of the projectile 5 increases. As a result, the projectile leaves the shutter 6 into the bore 2. This significantly increases the speed of the projectile 5 in barrel channel 2.

Projectile 5 flies out of barrel 2.

Gases (see Fig. 6) fly out through the bore 2 and the channel 27 of the shutter 6 into the atmosphere. When this happens, the pressure decreases in the chamber 28 of reduced pressure, in the channel 24 for supplying gas (s) to the diaphragm 14, in the chamber 25 of high pressure. In this case, the valve 31 of the channel 30 closed the window 57 for supplying pressure to the channel 30 of the gas distribution mechanism.

Under the influence of the energy of the propelling gas, the spool 7 of the shutter 6 moves towards the chamber 28 of reduced pressure. When this happens, the pressure relief channels 44 of the spool 7 of the gate 6 are aligned with the pressure relief channels 45 of the gate 6. The spool 7 of the gate 6 engages with the piston 8 of the gate 6. As a result, the gate 6 begins to move towards the chamber 28 of reduced pressure. In this case, the narrowing 29 of the chamber 25 is blocked by the widening 26 of the shutter 6. In this case, the spool 7 of the shutter 6 and the piston 8 of the shutter 6 displace gases from the high pressure chamber 25 and the low pressure chamber 28.

The piston 8 of the shutter 6 (see Fig. 7) enters the chamber 28 of reduced pressure. This increases the pressure in the chamber 28 reduced pressure. Gases from the low pressure chamber 28, through the gap between the channel 27 of the gate 6 and the nozzle 10, are forced out into the channel 27 of the gate 6. From the chamber 25 of the high pressure, the gases are expelled into the channel 27 of the gate 6 through the combined pressure relief channels 44 of the spool 7 of the gate 6 with channels pressure release 45 of the shutter 6. This reduces the speed of movement of the shutter 6 and the spool 7 of the shutter 6. With an increase in the rate of outflow of gases through the gap between the channel 27 of the shutter 6 and the nozzle 10 from the chamber 28 of reduced pressure, it leads to a decrease in pressure in the gap and the possibility the implementation of the supply of liquid through the nozzle 10 into the channel 27 of the shutter 6. With further movement of the shutter 6 and the spool 7 of the shutter 6 (see Fig. 8), to its original position under the influence of the energy of the projecting gas, the broadening 26 of the shutter 6 comes out of the constriction 29 of the chamber 25. The gases rush through the narrowing 29 of the chamber 25, through the channel 39 of the rammer 40 of the shutter 6 through the bore 2 into the atmosphere. There is a release of pressure in the high-pressure chamber 25, in the channel 30 of the gas distribution mechanism, the cylinder 33 of the spool 23. In this case, the spool 23 of the gas distribution mechanism, under the influence of the elastic force of the spring 34 of the spool 23, moves in the cylinder 33 of the spool 23, sucking gases from the atmosphere through the breather 35. When this happens, the speed of movement of the shutter 6 decreases, followed by the rotation of the shutter 6 along the axis of rotation of the shutter 6 and its stop. This is implemented as follows. The shutter 6 and the spool 7 of the shutter 6 continue to move by inertia. In this case, the movement of the spool 7 of the gate 6, towards the chamber 28 of reduced pressure, leads to the closing of the pressure relief channels 44 of the spool 7 of the gate 6 by the walls of the chamber 28 of the reduced pressure. As a result of the increase in pressure, the speed of movement of the spool 7 of the shutter 6 decreases and the piston 8 of the shutter 6 disengages. the stop 46 of the protrusion 9 of the shutter 6. The guide stop 46 of the protrusion 9 of the shutter 6 rotates the shutter 6 relative to the axis of rotation of the shutter 6. In this case, the protrusion 9 of the shutter 6 stands on the stop line 20 of the protrusion 9 of the shutter 6.

The groove 37 of the rammer 40 of the shutter 6 (see Fig. 8) is aligned with the window 55 of the projectile feeder. The projectile 5 enters the groove 37 of the rammer 40 of the shutter 6.

At the same time, the supply of gas (s) is automatically resumed, the energy of which (s) is used to carry out, in the automatic mode of firing, to re-execute a shot, in a single mode of firing, to set the shutter to the position of readiness for a second shot. This is implemented as follows.

The spool 23 of the gas distribution mechanism (see Fig. 9), under the influence of the elastic force of the spring 34 of the spool 23, opens the channel 22 of the gas supply (s). The pressure increases in the high pressure chamber 25, in the channel 24 for supplying gas (s) to the diaphragm 14. In this case, the diaphragm 14, under the influence of pressure, displaces the liquid into the nozzle 10 from the liquid supply chamber 13. In this case, the liquid supply valve 12 closes the liquid supply channel 11. Through the nozzle 10, liquid is supplied to the channel 27 of the shutter 6. When the pressure in the high-pressure chamber 25 increases, the spool 7 of the shutter 6 moves towards the barrel 2 and abuts against the broadening 26 of the shutter 6. In this case, the shutter 6, moving towards the barrel 2, the protrusion 9 shutter 6 (see Fig. 10E) engages with the lever 50 of the pusher 21. In this case, the lever 50 of the pusher 21 (see Fig. 10D) with the protrusion 52 of the lever 50 of the pusher 21 under the stop 20 is engaged with the stop 20. Further movement in shutter 6 and spool 7 of shutter 6 is not possible. There was a delay in the shot in a single firing mode.

To continue firing, the shooter must release the trigger. The latch 17 (see Fig. 2), under the influence of the elastic force of the spring 19 of the latch 17, moves the pusher 21 of the escapement mechanism to its original position. In this case, the lever 50 of the pusher 21 (see Fig. 10B) turns the shutter 6 and disengages from the protrusion 9 of the shutter 6. In this case, the protrusion 9 of the shutter 6 remains on the stop line 20 of the protrusion 9 of the shutter 6. In this case, the shutter 6 rotates relative to the axis rotation of the shutter 6. The groove 37 of the rammer 40 of the shutter 6 is displaced relative to the window of the projectile feeder.

Under the influence of pressure acting on the spool 7 of the shutter 6 and the shutter 6, the shutter 6 is displaced towards the barrel 2 and engages the protrusion 9 of the shutter 6 with the stop 20 of the protrusion 9 of the shutter 6. The shot is fired.

For a second shot, in single firing mode, the arrow must be pressed on the trigger.

To fire a shot in the automatic fire mode, the shooter must switch the fuse 16 of the fire selection mode to the automatic fire position. This provides a longer stroke of the pusher 21 of the trigger mechanism (see Fig. 10G) compared with the stroke of the pusher 21 of the trigger mechanism (see Fig. 10B) in the single firing mode.

When the trigger is pressed, the pusher 21 of the escapement mechanism (see Fig. 10B) moves in the channel 48 of the pusher 21 of the escapement mechanism. The lever 50 of the pusher 21 engages with the protrusion 9 of the shutter 6. The spring 51 of the lever 50 of the pusher 21 presses the pusher lever 50 towards the trigger.

In this case, the protrusion 9 of the shutter 6 is displaced relative to the stop line 20 of the protrusion 9 of the shutter 6.

The protrusion 9 of the shutter 6 (Fig. 10D) disengages from the stop 20 of the protrusion 9 of the shutter 6 and stands on the line of the channel 38 of the pusher 15. In this case, the lever 50 of the pusher 21 by the protrusion 52 of the lever 50 of the pusher 21 under the stop 20 engages with the stop 20.

Further movement of the pusher 21 of the escapement mechanism (see Fig. 10G), in the channel 48 of the pusher 21 of the escapement mechanism, leads to the rotation of the lever 50 of the pusher 21 under the influence of the elastic force of the spring 51 of the lever 50 of the pusher 21. In this case, the lever 50 of the pusher 21 is the protrusion 52 of the lever 50 the pusher 21 under the stop 20 engages with the stop 20 and the protrusion 53 of the lever 50 of the pusher 21 under the pusher 21 engages with the pusher 21.

When the shutter 6 moves to its original position, the protrusion 9 of the shutter 6 (see Fig. 10G) engages tangentially with the guide stop 46 of the protrusion 9 of the shutter 6. The guide stop 46 of the protrusion 9 of the shutter 6 rotates the shutter 6 relative to the axis of rotation of the shutter 6. At the same time the protrusion 9 of the shutter 6 stands on the stop line 20 of the protrusion 9 of the shutter 6. In this case, the groove 37 of the rammer 40 of the shutter 6 (see Fig. 1) is aligned with the window 55 of the projectile feeder. The projectile 5, under the influence of the elastic element of the store acting on the pusher (not shown in the figure, the numbering is not assigned), enters the groove 37 of the rammer 40 of the shutter 6.

Under the influence of pressure acting on the spool 7 of the shutter 6 and the shutter 6, the shutter 6 is shifted towards the barrel 2 and the protrusion 9 of the shutter 6 (see Fig. 10Z) is tangentially engaged with the lever 50 of the pusher 21. The protrusion 9 of the shutter 6 is not included in engagement with the stop 20 of the protrusion 9 of the shutter 6 and stands on the line of the channel 38 of the pusher 15 and (see Fig. 8) the groove 47 of the protrusion 9 of the shutter 6. In this case, the shutter 6 rotates (see Fig. 3) relative to the axis of rotation of the shutter 6. The groove 37 of the rammer 40 of the shutter 6 is displaced relative to the window 55 of the projectile feeder.

There was no delay in the automatic firing mode. The fire will continue until the shooter releases the trigger. In this case, the latch 17 (see Fig. 2), under the influence of the elastic force of the spring 19 of the latch 17, moves (see Fig. 10B) the pusher 21 of the escapement mechanism and the lever 50 of the pusher 21 to its original position. In this case, the protrusion 9 of the shutter 6, when moving towards the barrel 2, engages with the stop 20 of the protrusion 9 of the shutter 6.

The weapon is put on the fuse by turning the fuse switch 16 of the fire selection mode. In this case, the fuse switch 16 of the fire selection mode blocks the movement of the pusher 21 of the trigger mechanism.

In an automatic caseless weapon, for a shot, it is possible to carry out a blank shot both in a single firing mode and in an automatic firing mode. In this case, the projectile 5 is absent and is not used in the production of a shot.

In an automatic caseless weapon, it is possible to use a shutter 6 for firing a shot, characterized in that in the channel 27 of the shutter 6 (see Fig. 5) there is a nozzle having a subcritical section of the nozzle 41 of the channel 27 of the shutter 6, a critical section of the nozzle 42 of the channel 27 of the shutter 6 and a supercritical section nozzles 43 of the channel 27 of the shutter 6, with the possibility of converting the internal energy of the gases into the kinetic energy of the gases of directional movement at the moment of the outflow of gases through the shutter channel.

Throwing gas under high pressure enters, through the channel 27 of the gate 6, into the subcritical section of the nozzle 41 of the channel 27 of the gate 6 through the critical section of the nozzle 42 of the channel 27 of the gate 6 into the supercritical section of the nozzle 43 of the channel 27 of the gate 6. Moving along the nozzle, the propelling gas expands, its temperature and pressure drops, and speed increases. The internal energy of the gas is converted into the kinetic energy of gases of directed motion. Throwing gas moves at high speed towards the projectile 5. The pressure from the bottom of the projectile 5 increases. As a result, the projectile exits the shutter 6 into the bore 2. This significantly increases the speed of the projectile 5 in the bore 2.

In an automatic caseless weapon, it is possible to use a shutter 6 (see Fig. 4) for firing a shot, characterized in that the shutter 6 is made with a broadening 26 of the shutter 6, the diameter of which is greater than the diameter of the piston 8 of the shutter 6, while after automatically stopping the supply of gas (s), the movement of the shutter 6 to supply the pressurized gas(es) to the reduced pressure chamber 28 is driven by the pressure energy of the gas(s). As a result of the pressure of the gas(s) on a large area of expansion 26 of the gate 6

In an automatic caseless weapon, it is possible to use a shutter 6 (see Fig. 4) for firing a shot, characterized in that the shutter 6 is made with a broadening 26 of the shutter 6, the diameter of which is less than the diameter of the piston 8 of the shutter 6, while after automatically stopping the supply of gas (s), the movement of the shutter 6, for the implementation of the supply of gas (s) under pressure into the chamber 28 of reduced pressure, is carried out with a slowdown in the direction of the barrel under the influence of the pressure energy of the gas (s). As a result of the pressure of the gas (s) on a large area of the piston 8 of the valve 6.

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