Revolver-automatic V. Gorobtsova

At one time, revolvers were the most progressive class of small weapons, because it allowed to make a series of shots without reloading. In the future, they gave way to self-loading pistols, which had several advantages. The use of automation and shops has greatly simplified the operation of weapons, as well as provide even higher performance. One of the most important differences between self-loading pistols and revolvers was the ability to create a store of almost any capacity. Ready-to-use ammunition revolver, in turn, depends on the size of the drum. Nevertheless, from time to time attempts are made to improve the characteristics of revolvers by increasing the size of the drum or other methods.

The original way to increase the ammunition of a revolver several years ago was proposed by the inventor V. Gorobtsov (patent RU 2130157). V. Gorobtsov developed an interesting construction of small arms, combining some features of a revolver and a self-loading pistol with a store supply. From the first class of weapons, the new weapon received a drum with chambers for cartridges, from the second - a magazine in the handle. It is argued that the proposed design of weapons allows you to automate the process of placing the cartridges in the drum chambers and extracting spent cartridges. As a result, a significant increase in the characteristics of a weapon with a revolving drum is possible.

All units of the proposed weapon (the inventor calls it a revolver-automatic) must be mounted on a common frame. Like on revolvers of classic design, the barrel of the weapon, located in the front upper part of the frame, with its rear section touches one of the four drum cavities. To seal the joint between the drum and the barrel, a special movable obturator is provided. The axis of the drum is proposed to perform hollow, inside it should be one of the most important structural elements - the gas piston, which activates all the mechanisms of the automatic revolver. The vapor tube is located in the front of the frame and connects the bore with the inner cavity of the axis of the drum.

In the neutral (extreme front) position, the gas piston should be held using a return spring located at the rear of the weapon. The back of the piston must be associated with various mechanisms that ensure the supply of cartridges, the extraction of spent cartridges and cocking the weapon. The front part of the piston is equipped with a pusher that is included in the screw grooves of the drum. This node is designed to rotate the drum in preparing the weapon for the next shot.

The back of the piston is connected to the feeder and rammer, designed to extract the cartridge from the magazine and feed it into the lower chamber of the drum. An interesting design of the store, proposed by V. Gorobtsov. The automatic revolver, as conceived by the inventor, should use a “longitudinally-double-row” shop. In fact, this store consists of two pistol stores of conventional design, assembled together. The feeder and rammer of the automatic revolver should alternately remove cartridges from both store halves. When moving, the feeder and the rammer seize the cartridges from both store halves and move them forward. The cartridge from the front "half shop" gets into the drum chamber, and the cartridge from the back takes its place. In place of the latter comes the next cartridge from the back of the store. At the next loading cycle, the process is repeated. For the extraction of spent cartridges, it is proposed to use an ejector with a tooth for its hook, located in the side of the weapon.

The trigger mechanism of a revolver-automatic machine designed by V. Gorobtsov has an original design and is made on the basis of cranks, cams and rods. The use of such a design, allegedly, simplifies the weapon, and also provides the possibility of operating the firing mechanism for firing both in single and in bursts. Provides for the use of an automatic fuse and translator of fire. The latter should be included in the design of an automatic revolver with the possibility of firing in lines.

For aiming the automatic revolver can have any suitable aiming devices. Depending on the ideas and ideas of the designer, the weapon can use both an open sight and systems of a different design.

The principle of operation of the original automation, combining the features of a revolver and a self-loading pistol with store supply, is as follows. Before shooting, the shooter cocks the weapon with a special lever on its side surface. An interesting feature of the automatic revolver is the fact that in order to prepare for firing, the cocking lever must be turned back and returned to the place not once, but three. The first time you press the lever, the cartridge from the magazine is placed in the lower chamber of the drum. The next two clicks are required to lead the chamber with the cartridge to the barrel and prepare the next two chambers. After this, the shooter can turn off the fuse and set the fire translator (in the case of automatic weapons) to the required position.

When you press the trigger, the trigger mechanism of the automatic revolver produces a shot. The powder gases in the barrel enter the gas exhaust tube and act on the gas piston. The piston, moving backwards, cocks the firing mechanism and also shifts the shutter. The drum is set in motion and rotates 90 °, with the result that the chamber with the new cartridge is at the level of the barrel. During rotation of the drum, the chamber with the cartridge case comes to the ejector. Extraction and release of the liner.

Returning to the neutral position, the gas piston actuates the feeder and the rammer, which places the new cartridge from the magazine (its front half) into the lower chamber of the drum. In addition, the obturator returns to its place, and the corresponding elements of the firing mechanism are brought to the back of the chamber. The weapon is ready for the next shot.

The automatic revolver designed by V. Gorobtsov is of considerable interest from an engineering point of view. The inventor managed to solve the problem of feeding cartridges into a weapon with a rotating drum, without resorting to cardinal solutions. In the fifties of the last century, the American gunsmith D. Dardic proposed a similar system with a magazine and a drum, but to ensure the interaction of these nodes it was necessary to create a new cartridge of a characteristic triangular cross section. The system Gorobtsova theoretically allows you to use any available pistol cartridge.

However, the proposed automatic revolver has some problems, including at the concept level. It is not entirely clear why we need a magazine-powered revolver, and what advantages does it have over existing self-loading and automatic pistols? The lack of an answer to this question makes it doubt that the original weapon will ever come down from the drawings and will appear as a valid sample.

The design of the automatic revolver was also not without ambiguous solutions. Thus, a two-row store of the original design, placed in the handle, can seriously complicate the operation of the weapon. For example, “longitudinally single-row” (using the terms of the inventor) the magazine of a pistol PM chambered for 9x18 mm has a width of the order of 27 mm. A “long-row” store at its base, actually consisting of two standard stores, will have a width of at least 50 mm. To this must be added the dimensions of the handle of the weapon, from which it follows that the ease of operation of the automatic revolver with the original magazine directly depends on the used cartridge. However, the problem of a large store can be solved by abandoning the second row of cartridges and using the classic two-row design.

With the cartridge is connected and the performance of the weapon. Not every pistol cartridge can be used in weapons with vapor-automatic. Features of the operation of such automation and its requirement for the energy of the cartridge imposes appropriate restrictions on the types of ammunition used. This, in turn, may affect the size of the store and the convenience - or even the possibility itself - of using such weapons.

Despite the strange decisions applied in the construction of V. Gorobtsov’s automatic revolver, this weapon is of some interest. The inventor was able to develop an interesting and possibly promising way to improve the characteristics of a weapon based on a revolving drum. However, as already mentioned, the future of this invention is hazy, since the meaning of using such a system and its advantages are completely unclear.

    Stillborn construction. The main advantage of the revolver is simplicity and reliability. The disadvantages of revolvers are their small ammunition and the complexity of the reloading process. In the hybrid, an attempt was made to eliminate the shortcomings of the revolver due to a significant complication of the design with a decrease in reliability resulting from this circumstance. The result is a sample, IMHO, which has lost the virtues of revolvers, but has no advantages over pistols. How engineering is interesting, but, I believe, nothing more.

      For the sake of justice, I note that in artillery, such an approach is not news:
      Swiss 30 mm KCA, 1350 rds / min,

      and German 27mm Mauser BK27, up to 1700 rds / min.

      Anti-aircraft MANTIS 35 mm, 1000 rds / min.

      True pistol, on such a system - yes, it’s pretty extravagant. GSH-23, not revolving, but also with combined chambering and extraction of the sleeve,
      turn into an easel machine gun, like and did not try. Despite the fact that even in a single-barrel version and with an 14 mm cartridge, this unit would be superior to KPVT. Probably, they decided that it was a little expensive and complicated for the land. Well to speak about small arms ...

    As usual, our online designers from the site know everything. But for me, it’s enough that a person created something original. Remember the story. How many delusional inventions were created in the first half of the century? But no less and brilliant things. I can only express my joy that human thought is developing in the Fatherland. I’m not a weapons designer, I can’t evaluate the invention, but I hope that if out of a dozen such ideas at least one is used, then it’s not in vain.

      On the contrary, it’s all just because the design idea is developing. Only in this case it develops in the wrong direction - it turns out to be a bulky and overly complex weapon that has lost the advantages of various principles - a revolver and a store pistol. This is the same dead end branch as the first store models of Mauser and Manliher - the store was located in front of the barrel, and the handle of the weapon remained ballast, as in a revolver.
      As a warm-up for the mind, this is a good invention, but in short-arms it is not applicable. Rather, it is suitable for multi-barrel designs.

    The main drawback of the revolver is the loss of pressure at the interface between the drum chamber and the barrel. The disadvantage was not eliminated, they just added a magazine so that there were more rounds. An absolutely common thing in the world of technology is invention for the sake of invention. Funny but pointless.

        You are right, of course. It’s shorter ... in general, the sleeve liner obturation is not a technically perfect solution, it is a fundamentally weak point of the structure, so to speak. If you want to do a truly perfect thing - in general take out the weaknesses of the working field. Well, for example, like that. Here the barrel of the machine gun is warming up, and all the parameters are falling. So the number of rounds in the box should be no more than that the barrel did not have time to overheat. And during the reload time, the barrel should cool down so that you can shoot another box.
        Designs without flaws are impossible. But it should be designed in such a way that the user never encounters flaws! And do not interfere with the bulldog with the rhino, maybe it will work ....

          most likely it’s necessary to adapt to the modern details of small arms, and it dictates the simplification of automation schemes, and the transition to a more sophisticated ammunition, for which there is a base of breech-loading mortar ammunition, but not in the literal sense of the word - mortar, this is the ammunition that is in the launcher the pipe does not leave anything other than gases - reactive-reactive, here it is necessary to activate the settlement discussions

          We change the design a bit and solve the flaw with the breakthrough of gases between the drum and the barrel, 17 more details appear in the structure, extend the barrel of the revolver and add the shoulder rest and get a sport-hunting rifle with magazine feed. We get at the exit a very expensive and rare design. We carry out tests and send to the weapons museum well and make 10-15 pieces for sale in order to recoup the costs of the entire process and in 10 - 20 years this weapon exclusive will go into collections. In my opinion, this is the only niche for the use of this unit))) hi

    all the same, my opinion is on the essence of the topic, design weaknesses are a charging mechanism, there are a lot of details that require reliability, although twice the strength, not to mention more, it does not have and cannot have this scheme due to the limited scope of the structure within designs like a pistol, for members of the forum, when developing easel and more weapons, the designer has certain advantages for using the dimensions of his products and the forms of energy supply to the reloading mechanism, but the author of such a puzzle is really an interesting designer,

    Difficult-ambiguous. And sealing the end of the charging chamber ??? This is generally an empty place. Type clearance within tolerance. Nagan even had a drum approaching the barrel before firing. Because of this, the sealing was not bad, but all one low speed of the bullet and low pressure in the barrel, which led to a decrease in the energy of the bullet. Both range and slaughter suffered from this. No, this is not our option. As an idea, it’s normal, but hereinafter ..... Personal opinion, I do not insist.
