Three-barreled automatic salvo fire TKB-059 of German Korobov

35
The TKB-059 volley fire automatic machine is a unique example of domestic design thought, created by the Soviet designer of infantry weapons German Alexandrovich Korobov (1912-2006). Three-barreled automatic (Pribor-3B) German Korobov created 1962 in the Tula Design Bureau.




The design of the machine is based on the Bullpup scheme (English bullpup) - this is the layout scheme of the small arms mechanisms, in which the percussion mechanism and the magazine are located in the butt, behind the trigger. This arrangement allows you to increase the length of the barrel without increasing the total length and weight of the weapon, which contributes to the improvement of characteristics in range and firing accuracy.

Herman Korobov, when creating the TKB-059, put an ultra-fast queue at the forefront in which the recoil from the shots did not have time to deflect the barrel, which allows for high accuracy of fire.

Several barrels on one machine allowed for a salvo shot, the rate of firing from the TKB-059 (Pribor-3B) submachine gun reached 1400-1800 shots per minute. Many units and parts of the Pribor-3B were borrowed from the Kalashnikov assault rifle, which made it possible to achieve a high degree of unification with the main small arms of the Armed Forces of the USSR.



The fire from TKB-059 was conducted either by volleys of three shots, or in bursts. Three barrels in the machine are assembled in a single carriage and have a common mobile automation system. TKB-059 showed unprecedented accuracy when firing bursts due to the super-speed and monitors the mounting scheme of trunks.

During the state tests, due to the simultaneous firing of three bullets in the queue, the weapon really showed very high accuracy. However, the unusual design and complexity of equipment built-in stores led to the fact that the state commission refused to accept this machine. The fact that the troops were armed with an AKM machine gun also played a role, and there was no need to retool a new type of small arms.

The TKB-059 automatic salvo fire (Pribor-3B) remained a prototype, but still it is the clearest illustration of the talent of the outstanding Soviet designer German Alexandrovich Korobov.

Performance characteristics of TKB-059 (Pribor-3B):

      And then Israel used the layout of the mechanisms in the stock, but with only one barrel, and gave it away as its know-how. So old ideas come to light of God ...

        An Israeli will come and say that more than 10 years have passed and declare the rights to use.

    and strangely enough bullpup in 1962 .. and when did the avtrtiyaks do their thing there? in 1977 if I’m not mistaken. So we were the ancestors of the result.

        By setting up bullpups maybe yes, but by setting up bullpups for vending machines the first who was? Korovin? Korobov with his TKB 408-2? or English EM-2?

    N-yes ..... It's not just original, but it seems very effective. A company of such machine gunners will be replaced by more than one machine gun ...

    Interesting machine.
    Has anyone understood where the spent cartridges are ejected?
    Understood:
    "Discharge of spent cartridges and exhaust gases is carried out forward to the muzzle of the barrels."

      Ideal for attacking an enemy trench. Shooting begins when the enemy is visible behind the parapet from a height of growth - that is, meters from 70. And with one shot, a bullet horizontal wall is immediately set! Moreover, shaking during running and the inevitable withdrawal of the barrel when shooting from a hand are practically excluded - there’s only one shot. Awesome thing.

    In fact, this machine can be made in the variant caliber 5,45.
    And since it can conduct salvo and fire at an increased rate of fire, it will not have the lack of stopping action of a bullet inherent to AK 5,45 caliber. Three 5.45 bullets, for any one, will kill 7,62.
    Based on this design, an excellent light machine gun of 5,45 caliber can be created and replaced with RPK 74 (index 6P18). The life of the weapon, before overheating, will be huge.

    This model was created to work out new principles, and not for arming. It was on this sample, in practice, that confirmation was obtained of the high effectiveness of the short high-temperature line on the monitors. Especially their precarious positions. The heirs to this principle were Stechkin and Nikonov assault rifles.

    By the way, a vivid example of the competition of Soviet times. Now it is customary to say that under socialism there is no competition, therefore everything is bad with the products, but this is a lie. There was competition, and the liveliest. It was simply brought to a more pragmatic level, because it was accomplished before the launch of any product in the series. Various engineers, designers and manufacturers competed at the pre-production stage of production. Then the commission selected the best by the sum of the parameters, and the best product was launched into the series. Sometimes a few, if required. Thus, there is no dispersion of forces and means, but different design bureaus are constantly working, talented teams and personalities are encouraged, and any work can be done quickly and on time, because the blade is always sharpened and cuts when necessary;)

    Now they’ve lost it, left at best one KB each, so there is no future for the country, and a genius like Korobov simply can’t do what he wants. The competition went capitalistically, not able to give the best product and work on it with the whole society and with all its might. In the West, they left part of the Soviet system (especially in Japan), leaving the state order, financing of various design bureaus and other structures at the expense of the state, so they are ready for war, but our profession is not :)

        Dear Droid, what about the three-bullet cartridge? (did they seem to do it?)

          With multi-bullet cartridges problems.
          Firstly, this is a decrease in the mass of an individual bullet, and secondly, an increase in the shape coefficient of the bullet and, as a consequence, a ballistic coefficient (according to domestic calculation methods). As a result, the deterioration of ballistics and a decrease in the range of effective fire.
          And if the Soviet two-bullet 12,7 mm cartridge 1СЛ, for the YakB aviation machine gun, copes with its task - increasing the density of fire and the probability of hitting targets up to 1000 m, then in small arms everything is worse.
          As an example, the American two-bullet cartridge M198.

            an American with a bevel bottom is not a good idea. As regards the reduction in bullet weight and, consequently, the shape coefficient, in contrast to tripartite mitrallise, the problem does not seem insoluble: increasing the length of the cartridge, increasing the barrel of the cartridge case, increasing the powder charge

              TKB-059 is intended solely for testing the concept of high-temperature serial volley on a montage scheme. This is not a weapon, but a "laboratory device."

              And now for multi-bullet cartridges with normal bullets. Take for example the 5,45 bullet. Its length is slightly more than 25 mm, for the convenience of counting we take exactly 25 mm. Three bullets one after the other is 75 mm, minus 5 mm (the tip of the bullet enters the recess ahead), total 70 mm. This is slightly less than the rifle cartridge 7,62x54R. And you also need a place for a powder charge weighing ~ 4 grams. What will be the length of the cartridge? You can take a powder checker, a sort of pasta, where to put these bullets. Do not also forget about the outburst charge of sufficient mass and the bottom of the sleeve. This will add ~ 1,5 cm to us. Total 70 + 15 = 85 mm cartridge length, which exceeds the length of the rifle. This means that the course of the bolt group, and therefore the receiver, will be longer, and we should not forget about the length of the chamber. The mass and length of the weapon increases.
              Now let's see what happens with powder gases.
              In an American cartridge, the mass of two bullets exceeds the mass of a regular bullet by 11%, in our example the difference is 300%, 3 times. What will happen to the machine gun if you put a bullet in the barrel, then charge the cartridge and shoot? And we have 3 bullets in the cartridge. And the charge of gunpowder is triple. What will be the maximum and average pressure in the barrel in such a weapon? And if the thickness of the barrel and the chamber is increased, will the locking unit withstand? And if you design such a weapon, how much will it weigh and what will be its resource?
              Multi-bullet cartridges without such problems can be implemented only in the SPEL version. Cartridge of 9-10 mm caliber, in the pallet 3-4 SPEL arranged in parallel, with a total weight of 4-5 g (together with the pallet) But there are other problems. And I don’t see much sense.

                Come on, I was joking. I myself have never dug so deeply, more than two in one sleeve - and it would not have entered my head. I just saw how you were "for", well, it got carried away ... Actually, when I was young, I had the idea of ​​two barrels, but with grooves in different directions to compensate for lateral withdrawal, and three barrels ... even if arrange with a triangle - some kind of garbage. Well, the rest: three gas outlets (no less recoil), three shutters (I hope they are interchangeable?), And the concept itself is more like the working curiosity of a designer
