Downed on take-off: D-6 moto armor


By the time the D-2 motocars approached the series (read about the D-2 here: Unknown Nikolai Dyrenkov. Armored car D-2), - some of their shortcomings were already obvious, but in the framework of mass production, they cannot be eliminated. Therefore, in 1931, N. Dyrenkov turned to the UMM of the Red Army with a proposal to build a new motor-armored wagon with reinforced armament from an 107-mm cannon in a tower of circular rotation and with improved driving characteristics. The proposal was accepted by 27 on October 1931 of the year, but due to the overload of the Dyrenkov Design Bureau some drawings appeared only in the middle of 1932 of the year. Being forced to move the turret to the central part of the car - Dyrenkov placed the engine and transmission not in the middle, like in the D-2, but in the end of the motor vehicle. At the same time, Dyrenkov, being in his repertoire, offered in peacetime to carry passengers with this transport:

“In the program of work of the Institute of Mechanization and Motorization, presented to you in 1931, issues of the possibilities of extensive use of military vehicles in peaceful conditions were especially developed. Guided by these considerations in the design of the D-2 motor-armored car, the armored corps were designed by me in demountable, as a result of which, removing the upper part of the hull and the tower, you can put a light iron booth on the remaining lower chassis and use the chassis as a power truck.

When designing the D-6 armored car with a single turret, with an 107-mm gun, I had to transfer the engine and transmission mechanisms from the middle of the car to one end in order to have a place for the gun turret, which makes it possible to use the undercarriage in peaceful life as a passenger railcar. The D-31 body that I designed for this running gear makes it possible to locate 102 passenger seats on it.
In addition, to further simplify and reduce the cost, I have designed a new D-35 transmission for the D-6 undercarriage, which involves the use of an I-2 ordinary gearbox instead of an 2 speed clutch and 5 speed reverse gear in combination with a reverse gear, dressed directly on the wagon axis, which reduces the number of transmission details on 1104 pcs. and weight (approximately 0,5 t). By bringing the above to your consideration, I ask you to approve the D-6, D-35 and D-46 projects attached herewith and allow them to be built according to the same design. "

Downed on take-off: D-6 moto armor

However, if you noticed, the photos of the D-6 are very different from the one that is supposed by the descriptions of the appearance. What is the matter, why neither 107-mm guns, nor circular fire is not detected? The fact is that the Experimental Design and Testing Bureau of the Office of Mechanization and Motorization of the Red Army in December 1932 was disbanded, and Dyrenkov himself was appointed Deputy Director and Head of the Department of Mechanization and Motorization of NATI.

The development of the D-6 in a trivial fashion was "stuck" at the semi-ready stage. The problem was that the self-taught Dyrenkov did not issue a ready-made set of drawings to production, but delivered them as the machines were manufactured — accordingly, when the OKBM UMB was disbanded, there was simply no one to finish the drawings.

The project of an armed 107-mm armored rubber was in limbo ...

"Motobronewagon with the engine" Hercules "105 hp (D-6).
The upper and lower parts of the hull, the tower body without shoulder straps, the mast and the turning mechanism were made. A running gear with hand brakes, a Hercules motor with an I-5 gearbox and a D-35 reverse, a Kommunar type radiator are installed. Installed silencers, pipelines, as well as a temporary gas tank and temporary control of the armored car. In this form, the system will be ready for testing by 10.12.32. Further assembly is delayed due to the absence of drawings. ”

Transferring the employees of the OKIB to the disposal of the plant Mozherez helped the case slightly, because trying to get rid of someone else's development as quickly as possible - the plant management decided to finish building D-6 as an improved version of D-2. They rationalized the armored hull, making it noticeably lighter, expanded the armored jacket. The tumbling installations of the guns were replaced with normal turrets with the suspension of the gun to the rotating turret - however, they did not take the 107-mm guns, but the same, 76-mm guns of the 1902 model.

The tests of the trolley were brilliant, the guns fired without problems, but the maintenance of the guns in these towers was inconvenient. Therefore, it was decided that to change the less advanced, but already in production D-2, to such D-6 - there is no sense. The game was not worth the candle. But, already built armored car was accepted for armament, the good should not be lost.

The combat service of the D-6 motobroner car took place in Transbaikalia, along with other Dyrenkov non-serial machines, the D-3 and the D-2 prototypes.

    Dyrenkov unknown ?! Ha! He has only three standing samples, and the rest ...... was interrupted on take-off (one idea, without blueprints, strength calculations ...). Although not one of his offspring lived up to the war.

      Dyrenkov was talented in ideas, but the adventurer is the same ... This is so.
      I didn’t even really make blueprints and toiled with maintenance.
      But the idea was great.
      Why is it so to blame?

      And that "did not survive" before the war?
      D-2 was built 30 pieces (15 in Moscow, 15 in Bryansk)
      D-2 participated in the Second World War.
      Moreover, 7 NKVD armored vehicles were captured by the Germans, repaired and ... included in the German army. But the Germans understood a lot about technology.

      D-2, D-3 and D-6 continued their service in Transbaikalia and were decommissioned at the end of the 40's, so they survived the war.

      Here are the Germans, radishes, studying D-2:

        D-2 participated in the Second World War.

        ... They jumped out to the outskirts by car and see how more than two dozen enemy tanks creep along the highway. Our motorcycle company departs in front of them, sent on the eve of intelligence. Critical situation! The enemy is about to break into Dmitrov, and here is the army headquarters, and there are no troops.
        And then, fortunately for us, an armored train appeared on the line of the Yakhroma-Dmitrov railway. He fired straight off. The driver then threw him forward sharply, or just as swiftly led him back. When the armored train came closer, we [308] with the communications chief Lieutenant Colonel A.Ya. Ostrenko ran up to him.
        Jumping on the bandwagon, I knocked on the tower. Two fresh holes and a few dents gaped in the armor. The hatch opened, a man in a leather jacket appeared, which had previously been worn by tank commanders, but without insignia, his face was stained with fuel oil.
        “The commander of armored train No. 73 is Captain Malyshev,” he introduced himself. - I’m fighting, destroyed eight tanks.
        - Where did you get here from?
        - Sent yesterday was the commander of the Moscow defense zone.
        - And who is leading the fire?
        “This is my second armored site.”
        It turns out the train consisted of two independent armored sites, armed with guns, machine guns and anti-aircraft guns. Combat armored trains with 20 tanks! A rare case ...

        It was possible to use motor armored cars separately. This is an example of such an effective application. And it was D-2.
        Dyrenkovsky motorized armored cars were certainly not a fountain, but they fought, and not weakly.

          Well, here's a real episode that clearly shows that armored cars are best, and armored trains could be used in a maneuverable defense, like a "fire brigade", but I wonder how to use them in an offensive?

        But the same D2 but ...
        The crew of the D-2 armored car is discussing the wall newspaper with the decisions of the VII Congress of Soviets. Winter-spring 1935 ……… .. Pay attention to the unusual helmets of the French model on the heads of the lich. composition.

          Yes, unfortunately, they understood and appreciated, but by evaluating themselves they began to create something similar

    And of the armored cars (if we compare with the Dyrenkovskys), the brainchilds of the Kirov plant were interesting, but only 2 of them were built and they were not at all "small" compared to the D-2.
    Both took part in the battles.

    ... The performance characteristics of the MBV-2:
    length: 19,2 m;
    booking: front sheets of the hull, turret and commander’s rubles - 20 mm, side sheets - 16 mm, roof - 10 mm;
    combat weight: 80 t;
    armament: three tank guns of caliber 76,2 mm, four anti-aircraft mount 4M (Maxima 4), two anti-aircraft machine guns DT (!!!) and two Maxim machine guns on each side;
    number of axles - 5;
    engine: M-17T power 500 hp (368 kW);
    maximum speed: 120 km / h;
    maximum speed with train: 100 km / h;
    power reserve: 500 km;
    crew: 34 person, incl. 4 officer (commander, his assistant, commissioner and assistant commander for technical affairs) ...

    I first discovered here that something Dyrenkovo ​​fought. I saw a live Dyrenkovo ​​armored car - this is a capsule of death, how it was possible to use weapons! But we must pay tribute to his ingenuity and resourcefulness.
