Automatic bezgilzovy gun Gerasimenko VAG-73

29
For all history small weapons A huge variety of systems have been developed. The sleeveless weapon is quite interesting, but if you ask interested people about it, many will take as an example only the German machine G11. Probably, someone will remember that the Germans were developing a light machine gun and a PDW submachine gun for the same cartridge. A person studying the history of weapons in depth will cite as an example the competitors of this system - Mauser and Diehl, who participated in the same competition. For this weapon was used ammunition, which is a bullet pressed into a parallelepiped made of explosives. For the American MBA Gyrojet pistol, also related to the caseless weapon, so-called reactive bullets were used.


Automatic bezgilzovy gun Gerasimenko VAG-73


In addition, another version of ammunition was used - it consists of a head part (metal) and a hollow thin-walled rear part, made in the shape of a cylinder. The rear part serves as a sleeve inside which a propellant powder charge and a burning capsule (charge of a flammable substance) are placed. The cartridges of this type are used in the Benelli CB-M2 submachine gun (Italy) and in the experimental submachine gun design of the Zhetesov RPG-005 (Kazakhstan).

It can be summed up: when it comes to caseless weapons, experts recall many countries, not the USSR or Russia. But this is unfair - in the Soviet Union developed such systems.

At the end of the 1980-s, the Kiev State Security Committee handed over a pistol to the Weaponry funds of the St. Petersburg Artillery Museum without any accompanying documents. This weapon was developed by Vladimir Alekseevich Gerasimenko (1910-1987) and had a highly unusual design.

The emblem of Arsenal, a plant that was engaged in optical aviation systems for space and aviation.



At this plant, Vladimir Alekseevich worked with 1942, the design engineer. Gerasimenko, on his own initiative, developed and designed combat and sporting pistols, while his work was carried out under the supervision of the KGB. Over the years, he developed about 20 experienced weapons and obtained 7 certificates for inventions. Interestingly, Gerasimenko did not have any weapons education.

At the beginning of the 1970-s Gerasimenko designed and manufactured automatic guns VAG-72 and VAG-73 under the 7,62-mm cartridge-less cartridge.

In addition to the VAG pistols, the 9-mm pistol for the 9x18 PM ammunition and the Gerasimenko 7,62-mm pistol for the TT ammunition were transferred to the funds of the museum after the death of the designer. True, these guns have quite an ordinary design.

Constructive features of Gerasimenko's sleeveless pistols:

The gun itself has quite impressive dimensions and mass - with dimensions of 235x135x28 mm its weight is 1,2 kg.

The trigger mechanism allows you to make a shot of self-cocked or with a preliminary cocking of the trigger. In the gun there is no external safety device, but there is a two-way translator of firing modes. Both single shots and bursts can be fired.



The receiver unit with the frame of the pistol is connected with a vertical pin fixed by a transverse axis.

The AVH-73 has a rather interesting power system. The “tandem” magazine holds 48 cartridges (in the VAG-72 store - the 24 cartridge). In fact, these are two stores, placed one behind the other in a single package with separate supply springs. Shops of this type are also used in the Russian OZ-53 submachine gun.

Sending the cartridge to the chamber took place according to the following scheme: with the magazine attached and fully equipped, when retracted to the rearmost position of the bolt, the gate larva goes behind the ammunition in the front compartment of the shop, and the larva feeder behind the ammunition in the rear. During the movement of the bolt to the front position, the front cartridge is fed by the larva into the chamber, and the cartridge from the rear compartment of the magazine takes its place.

The receiver unit is connected to the frame of the pistol with a vertical pin fixed by the transverse axis


Thus, during the shooting, cartridges from the back of the magazine were first spent. Each cartridge was first fed to the place of the upper cartridge of the front of the store, and only then, during the next reloading cycle, into the chamber.

Ammunition from the rear compartment of the store was attacked by the gate larvae feeder.

The larvae feeder after 24 shots (using up all the ammunition in the back of the magazine) without meeting a cartridge in its path, worked to idle. At the same time, the front part of the larva during each cycle fed into the chamber of the cartridge from the front of the store.

In order to provide effective aiming in automatic mode, the VAG-73 design is supplemented with a pneumatic moderator (it is absent in the VAG-72). The retarder slowed the bolt when it rolled forward, which made it possible for the pistol to return to the aiming line when firing bursts.

The design of the pneumatic moderator is quite simple. There is a valve opening in front of the cylinder.

During the movement of the shutter starts to back its lower part interacts with the moderator lever, which moves the aluminum piston forward. At the same time, the air in the cylinder leaves through the valve located in the front part - a vacuum is formed. During the roll-up of the bolt, he encounters the other lever arm of the moderator on his way and, overcoming the resistance of the cylinder held by the vacuum in the cylinder, continues to move. As a result, the shutter moves a moment later to its most forward position. This is quite enough for the pistol to return to the line of sight before the next disruption of the trigger during automatic shooting.


The cartridge from the “rear” magazine is harvested by the feeder of the shutter larvae (indicated by the arrow)


The mechanism of the translator of fire modes works as follows. Depending on the position in which the translator of fire modes is located, the trigger pusher either moves up and down freely or is rigidly fixed. Two shoulders lever, connects the pusher and sear.

When the trigger is cocked while pulling the trigger, it presses the front of the two shoulders lever on the left side of the shutter larva. Pressing occurs through the movable pusher. At the same time, the rear part of the lever lowers, presses the sear, the trigger breaks off from the platoon - a shot takes place.

If the translator is set to single-fire mode, after the shot, the trigger pusher with the lever's front lever moves downward when the shutter returns.

Pneumatic moderator is quite simple in design. Well visible valve hole in the front of the cylinder


When the trigger is pressed in the automatic mode, the pusher, pressing the lever, is fixed in the upper position. During the forward movement of the bolt, the lever stumbles upon a pusher and its front part rises — a sear is lowered, a shot occurs.

Part of the firing mechanism with a mainspring, a sear and a trigger is easily removed from the frame. When fired with an unvoiced trigger, the thrust located inside the frame of the pistol is activated, which connects the trigger and the trigger.



The USM part with the trigger, the sear and the mainspring is easily removed from the frame of the gun. In the production of a shot with an unlocked trigger, the thrust connecting the trigger to the trigger, inside the frame of the pistol, is activated.


Ammunition to the pistol Gerasimenko VAG-73

For bezgilzovyh systems used several types of ammunition. This may be a bullet pressed into a parallelepiped of an explosive (German automatic G11) or the so-called reactive cartridges (American MBA Gyrojet pistol).

The bullet to the guns Vah belong to the third type. Also, these munitions are called a cartridge with a "flying away" sleeve. The ammunition consists of a metal head and a rear hollow thin-walled part, made in the shape of a cylinder (cup). Inside the back of the cartridge, there is a propellant powder charge and a burning capsule (there is a thread for screwing it in) - a charge of a flammable substance, that is, it serves as a sleeve.



Cartridges having a similar design are also used for the Benelli CB-M2 submachine gun (Italy) and the experimental submachine gun pistol of the design Zhetyosov PPZH-005 (Kazakhstan).

At first glance, cartridges for VAG pistols raise legitimate questions. Made of steel, they should “eat” the barrel after several dozen shots, but brass cork, screwed into the bottom of the bullet, prevents this. The function of the leading element performs a speaker belt. A similar master device is available in the artillery projectile and the PPS bullet.

In some sources, VAG ammunition, referring to the features of the classification, even in spite of a small caliber, is counted as a projectile. The use of a thick steel shell in the construction is explained by the need to eliminate its expansion by powder gases, and hence friction against the walls of the barrel during a shot.

    Thanks to the author for this article. Very interesting design as a pistol and ammunition. We were able, nevertheless, to do the necessary things at Arsenal. It is a pity that I did not go into the series. For special forces would be just right. It is a pity that you can put only one plus .... hi

      Well, straight, so sorry. And what, without this design in special forces there is nothing to use? Yes, a curious thing, but no more. Not given and the characteristics of weapons, except for bulky. In the future, we can still learn about all sorts of different developments, as we remove the secrecy stamp, of which we do not even suspect yet. It is not at all necessary that every curious model should have been in the series.

    I don’t understand in principle - why in small arms there is a case-less ammunition: to save non-ferrous metals? increase rate of fire? simplification of automation? Although the VAG cartridge is interesting ... And soot from a burning capsule - not too much? And maybe it’s better, after all, to press in, and not the thread ...

      Perhaps in this case there is reason to believe that simple pressing can not do. The capsule can simply fly out of the seat and the weapon will jam. And to break the thread, it is necessary to stretch it more than once and it will not work. Everything is done right.

        Well, bullets of ordinary cartridges do not jam? .. I suppose this is some kind of plastic, a little larger in diameter, stuck in a bullet and expanded; in addition, this connection does not work at all when recharging

                  And with rubber bands, how can you get there. Once I saw BMV immediately after the war, and on the road. In 1989 he still had his own oil seals. There you go.

      What for?
      1. Pay attention to the ammunition of this product.
      2. The entire mass of the projectile flies to the target (together with the sleeve). Those. the ammunition can be made smaller and generally lighter, with comparable characteristics to conventional. This means that a fighter can take with him a much larger ammunition. (Well, saving on sleeves, of course).

      This is an experimental sample.
      At the first stage, it was important to just start the automation without damage. It was necessary to start with minimal energies. Therefore, the cartridge is made collapsible to use a different amount of gunpowder. After all, there was no prototype.

    "At first glance, the cartridges for VAG pistols raise legitimate questions. Made of steel, they must" eat "the barrel after several dozen shots, but the brass plug screwed into the bottom of the bullet prevents this. The protruding belt performs the function of the leading element."

    One lead belt? what In theory, the projectile should still hang out, having one point of contact with the barrel. And why, in order to avoid bloating, not make the sleeve steel, and its continuation not be pressed into a lead bullet with a shell for the diameter of the channel? True, the production of ammunition will be more expensive, but so it is not a mass weapon. In general, such samples are more likely from a series of technical oddities, the scope of such weapons is unclear.

    The design is interesting. But in view of the complexity of the design, it seems to me that the sensitivity to contamination is much higher than that of pistols with classic automation systems. Although this gun is experimental, it is unlikely that he was in the field tests.
    It would also be interesting to know the combat characteristics, namely the accuracy of firing in single and automatic mode.

    The store deserves special attention - 24 rounds in the store, not protruding beyond the dimensions of the handle, this is clearly good.

      Experiments with reactive bullets have been going on for a long time, since the 40s.
      Some examples of sleeveless weapons even went beyond the framework of design developments and reached small-scale production, back in the 70s. In particular, a Benelli submachine gun. But no one took them into service.
      Concerning "ammunition, which is a bullet, pressed into a box made of explosives", the problem of long-term storage of such ammunition has not yet been resolved. Such ammunition is sensitive to storage conditions. And indeed there are a number of problems. If they were not, then traditional ammunition would not have been produced for a long time. In particular, shellless ammunition has not solved the problem of obturation.

        In Soviet developments, there was a cartridge made of a burning varnish with a powder filling and a clad bullet. The initiating composition was mounted at the bottom of the sleeve and rested on pressed powder, which served as an anvil.

    A jet bullet has a low initial velocity, and this is the minus of such structures.
