Description

The Automatic Shooting Non-Ammunition Weapon

The field of technology

The invention relates to armament, namely, to automatic non-ammunition weapons, in particular, to weapons using the energy of explosion of a mixture of gas, flammable liquid or other mixture in internal combustion chambers. The invention can be used all types of automatic weapons.

The previous level of technology

The "System of Automatic caseless weapons" (RU 2122170, Classes of The International Patent Classification (IPC) - F41A 9/28, F41A 5/00, F41C 3/14, Published: 20.11.1998, the author - Cvetkov C.A.) is already known. It includes a barrel, a bolt, a bolt carrier with a gas piston, a return mechanism and a 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 the removal of unburned particles of propellants. Camora, located in the upper position, has the ability to perform the function of the chamber. The discharge tube of unburned propellant particles is located in the front part of the receiver, with the possibility of aligning with the front part of the turret chamber when the ammunition is sent to this chamber. The shaft of the drum is a piston rod. Due to the presence of several chambers of a revolver, one of which participates in the shot, while the others are cooled, the enhanced ventilation is carried out by the blades of the revolver drum, and as the author considers, thus eliminating the danger of self-ignition of deadly ammunition.

The disadvantages:

• The use of caseless cartridges only;

• A complex shock-trigger mechanism;

• There is no connection between a cock and a trigger. A patent "Cartridge automatic weapons" (RU 2578466, IPC Classes - F41C3 / 00: 27.03.2016, Author - Rogulchenko AM) is already known. It contains a barrel, a box with a gas channel, a foreground, a barrel box, a bolt wedge, a chamber shutter, a wedge seat, a powder cartridge and a bullet cartridge. The bullets and gunpowder are loaded into the weapon separately into its different parts. The bullets are loaded from the bullet clip into the barrel, where the bullets then move to the barrel. The gunpowder is loaded from the powder cartridge into the powder chamber, where it then moves to the chamber, where the combustion of the powder occurs, from where the powder gases through the gas-conducting piston of the chamber's gate enter the barrel where the bullet is driven. It is possible to use various munitions in such weapons.

The disadvantages:

• The use of a bulky and heavy cartridge for the gunpowder;

• The complexity of a construction.

The task

The tasks of the invention are: ) the creation of an automatic caseless weapon system without the noted drawbacks with a bullet engine that is reusable enough to produce 500 shots;

) the replacing of the powder with a more efficient, compact flammable mixture;

) the minimizing of the deposit in the barrel;

) the reducing of a weight and a length of the machine;

) the reducing of a recoil;

) the creation of a transportable ammunition for up to 720 bullets without increasing the total weight of the soldier's outfit. The specified problem

This task is achieved by using gas in the weapon instead of gunpowder, that readily ignites liquid or another mixture (hereinafter gas) placed under a pressure of more than 15 atmospheres per cylinder. The gas, coming through the metering device, is mixed with the air in the mixing tube and the piston under pressure is fed into the upper internal combustion chamber through aligned 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 ratio of 1:20, will suffice for the production of more than 500 shots.

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

The chambers are made in the form of oblong cylinders united in a drum. A cross-section of combustion chambers may varies from round to trapezoid. Bullets enter the staple of the machine vertically and are inserted into the chamber when the drum moves to the trunk by fitting the chamber nozzle onto the bullet's tail. When turning the drum around its own axis and its longitudinal movement, the bullet of the upper chamber is sent to the trunk of the machine. The use of several internal combustion chambers in the course of the shooting, the system of blowing the chambers after a shot with compressed air, and also the supply of a mixture to only one upper chamber allow the chamber to be cooled and ready to fire, also by rotating the drum. It eliminates the arbitrary and premature ignition of the mixture.

The original layout of the machine, the lack of a shock mechanism, the use of the store as a stock, and the placement of a bullet in the barrel chamber of the barrel can significantly reduce the weight of the machine and its length.

The shot's impact is reduced by using oblong holes for exhaust gases at the end of the gas tube, which, as the piston approaches the muzzle, increases the size of the holes and slows the piston stroke. The shot's impact is reduced by the direction of the powder gases in the gas tube and the piston with the rod moving towards the barrel's muzzle. The shot's impact is also reduced by the use of a spring-loaded drum and a weighted magazine stock.

The several times' increase of the transportable ammunition load without increasing the overall weight of the equipment is achieved by the fact that only bullets (that are much lighter than the cartridge) are transferred. Also such increase is achieved by the using of a multifunctional high-capacity magazine made in the form of a box inside which there are clips with bullets. The store serves as a butt, as a box of a store made of composite bullet-proof fabrics or materials and has the function of armored plates on the bulletproof vest.

With the transfer of 8 spare magazines on the soldier's body in the form of armored plates, the transferred ammunition increases to 720 bullets. The weight of the armor is reduced by the use of "box" armor, the upper layer of which, due to depreciation, significantly reduces the kinetic strength of the bullet, and the reinforcement of armor protection by means of clips and ammunition.

The essence of the invention

The automatic caseless weapon, arranged according to the bull-pop scheme, contains a barrel (5) with a hole (33) connecting the bore of the trunk to the gas tube (12), a barrel-shaped box in the form of a cylinder (2) passing into a rectangular box (7), several internal combustion chambers (26) which are combined in a drum (3), the trigger mechanism (9), the piston (23) of the mixing tube (45). It is used for preparing and supplying of the mixture to the upper combustion chamber (26) and supplying of the compressed air through the air purging tubes (14) after the shot, connected by the rod (24) with the piston (34) of the gas tube (12). The automatic caseless weapon also contains the compressed gas cylinder (18), the ignition mechanism consisting of a piezoelectric cell (28) and spark plugs (25), a spare ignition system consisting of an accumulator (35) and a condenser (36), a gas outlet mechanism with a gas tube (12) and a piston (34) in which the gases are directed towards the muzzle, the return mechanism of the drum (3) in the form of a spring (39).

The bullets enter the staple (27) of the machine vertically from the magazine (55) and are inserted into the chamber (26) as the drum (3) moves to the muzzle cut by fitting the nozzle of the chamber (26) to the tail portion of the bullet. When the drum (3) is rotated about 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), a needle spring (40) and a nozzle (42). During the pressure of the piston (23) at the needle (21), it goes down 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 the dispenser (22).

The piston (23) is tightly connected by a rod (24) to the piston (34) of the gas tube (12). As the piston (34) moves under the influence of the "powder" gases towards the muzzle, the piston (23) pulls the dispenser (22) behind it by a sufficient distance to close the dispenser (44) of the mixing tube (45). At this time the needle (21) under the influence of the spring (40) closes the gaps with the nozzle (42), stopping the flow of gas into the dispenser (22). The fixation of the dispenser (22), when it is pulled by the piston (23), is produced by the antennae (54) of the needle (21). Meanwhile, gaps are formed between the walls of the shaped hole in the rear wall of the dispenser (22) and the outer walls of the nozzle (42). Through these gaps air is introduced into the dispenser (22) with the help of the apertures (41). An additional air blower in the mixing tube (45) is the moving back drum (3). The piston (23), moving towards the muzzle, creates a vacuum in the mixing tube (45), thereby drawing gas into the tube (45) together with the air, thus mixing them.

When the piston (23) moves by the spring (31) towards the side of the balloon (18), the dispenser (22) under the influence of the created pressure of the gas mixture in the tube (45) returns to its original position by closing the hole in its front wall with a needle (21). In this case, the piston (23) creates pressure in the mixing tube (45) and, through the aligned holes (43), (44) of the tube (45) and the upper combustion chamber (26), drives the gas mixture into the combustion chamber (26), compressing it to a few atmospheres and, in the final stage, closes the aperture (44).

At this time, the hook (30) of the rod (24) hits the piezoelectric element (28), which results in the generation of energy and the burning of the mixture in the upper chamber (26) by a spark between the electrode of the candle (25) and the wall of the chamber (26). The production of the spark only in the upper chamber (26) occurs due to the fact that one contact of the piezoelectric element (28) is closed to the drum body (3) and the second contact (46) is attached to the upper frame (4) of the cylindrical receiver (2) and comes into contact with the candle electrode (25) when the bullet is in the barrel (5) and the machine is ready to fire. The shot occurs then.

Powder gases push the piston (34) of the gas tube (12), and together with it, the hook (30) towards the muzzle. Before reaching the opening (33), the powder gases close the contact (32) of the relay (19) and the locking mechanism (20) is opened with the release of the drum (3). The powder gas residues shift the drum (3) to its extreme left position.

The shutter (6) is inserted into the machine through the shaped window (17) of the receiver (7) and fixed by the rod (24), that is the axis of the shutter (6).

When the shutter (6) is retracted, it closes the contact (47) of the relay (19) and opens the locking mechanism (20) and then influences the drum (3) and moves it to the extreme left position by compressing the return spring (39). By releasing the bolt (6), we operate the return spring (39) which pushes the drum (3) forward and it sticks the back of the bullet with the bottom chamber (26), fixing it in the chamber nozzle. When the bolt (6) is withdrawn forward, it advances the hook (30) of the rod (24) together with the stem (24) and the pistons (23 and 34) to the rightmost position, until the hook (30) is hooked by the sear (38). The spring coil (29) does not allow the shutter (6) to move with the stem (24).

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

The rear plug (1) secures the gas cylinder (18) and the magazine (55) in the machine.

A backward movement of the drum (3) is carried out by powder gases, and a forward movement by a return spring (39).

The drum

The drum (3) represents a few cylindrical cylinders (26) connected to the drum (3) around the tube-axis (48). The drum (3) rotates freely on this axis and also moves axially in the longitudinal direction. The chambers (26) are arranged along the axis of the drum (3), and their nozzles have a diameter that allows to be mounted on the tail portion of the bullet. The tube-axis (48) protrudes from one side beyond the drum (3) and on the protruding part there are shaped grooves (49) that mate with the lock (50) and due to which the drum (3) moves along the axis and rotates.

The trigger mechanism

It is arranged according to the bull pap scheme and consists of a body (9) with hooks (10) behind the protrusions (11) of the barrel (5), a profile (51) for fastening to the machine's handle (8), the protection bracket (52) of the trigger (15), the axes (53), the sear (38), the fuse (16), the hook (15), the oval (37).

By pressing the tail of the trigger (15), the oval (37) raises the sear's front end (38) upward, thereby lowering the sear's rear end (38) downward from the hook (30) of the rod (24). The trigger (9) is fixed to the machine by the hooks (10) behind the protrusions (11) of the barrel (5).

The safety device (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), limiting the movement of the rod (24) and the pistons (23, 34) in such a position that the tube piston (23) does not contact the needle (21).

The fuse has at least three positions:

1) The 1^st position: when the sear (38) and the rod (24) are blocked together with the pistons (23) and (34).

2) The 2^nd position: when the fuse's left end (16) falls down and releases the hook (30) of the rod (24). The fuse's right end (16) releases the sear (38) to such an extent that it is sufficient to fix the hook (30) of the rod (24) and release it to produce a shot. And while holding the trigger (15), the sear (38) descends and does not come into contact with the hook of the rod, which leads to a continuous production of shots.

3) The 3 position: when the sear (38) is not limited by the fuse (16) and when the trigger (15) is pressed, it acts on the oval (37), removing the sear (38) from the hook (30) sufficient to produce a shot. Upon further action on the trigger (15) and transferring it to the extreme left position, it leaves the hook with the oval (37) and ceases to act on the sear (38), that returns to the contact position of the hook (30). Returning to its original state, the trigger (15) raises the left edge of the oval (37) until the oval (37) stops mating with the radius part of the hook (15) is lowered and engages the work surface with its front part.

How the automatic machine works

Magazine (55) with its grooves (56) is inserted into the rectangular profile (57) of the receiver (2, 7) and by moving forward fastened to the machine and fixed on it from the transverse rolling by entering the U-shaped back of the handle (8). From the arbitrary exit of the magazine (55) from the slots of the machine, the back cover (1) is held.

The bullets go vertically into the machine and are fixed in the bracket (27) at the level of the lower chamber's nozzle (26). To charge the drum (3), the shutter (6) is shifted back, closing the relay contact, releasing the drum from the locking mechanism, after which the drum (3) is moved to the leftmost position by the shutter (6). From the extreme left position, the drum (3), due to the closing spring (39), moves forward to the barrel (5) and the nozzle of the lower chamber (26) is placed on the tail portion of the bullet and grasps it. To put a bullet in the barrel chamber (5) with the four chambers in the drum, this operation must be done for three times, so that the lower chamber (26) is moved upwards by the rotation of the drum (3) and the bullets are sent to the nozzles of the next two chambers. In this case, the piston (23) heats the needle (21) of the gas drum (18) and the gas fills the dispenser (22). With the help of moving the bolt (6) forward to the muzzle cut we compress the coil spring (31) and set the hook (30) of the rod (24) in the sear (38). Together with this the rod (24) is shifted forward simultaneously with the piston (23), and as a result of this, gas and air are drawn into the mixing tube (45). The machine is charged and ready to fire with the removed fuse (16).

The present invention completely solves the technical task of creating an automatic caseless weapon with a reusable bullet engine, by replacing the powder with compressed gas in a cylinder. It allows to abandon the cartridge and use only bullets and a compressed gas cylinder as an ammunition. The described solution allows to reduce the weight and length of the machine, minimizes the deposit in the barrel, reduces the recoil, and brings the transferred ammunition to 720 bullets without increasing the total weight of the soldier's equipment, and also strengthens the armored protection of the soldier.
