In this article we will talk about the first draft of the heavyweight tank, went down in history as "thetank Mendeleev. " Vasily Mendeleev (1886 — 1922) developed the project's own super-heavy tank in 1911. Working in the 1908 — 1916 years as a designer at a shipyard, in his spare time, he thought about how to make a machine that would be fine armor and invulnerable for a gun and artillery fire, had a devastating firepower, and could do it all delivered combat puzzle . As we know, he was a marine engineer, and his creation of the track down the main concept of building ships since then, and it is armadillos.
August 24, 1916 VD Mendeleev presented project for review. It should be emphasized that project has been designed very carefully to small details. Machine plan design reminiscent of a land battleship faster than usual for our awareness of the tank. In general, at the time, by analogy with the sea, the tanks were called land fleet. The design of the tank, although it is more appropriate title SAU, was a box-shaped housing length of 10 m (length with a gun — 13 m), the height of 2.8 m Reservations: forehead — 150 mm (cast steel plate), a board feed — 100 mm (Solid Plate), roof — 76 mm (5 assembled from cast slabs) it was very highest figure at the time. Such armor withstands 152 mm. The car was virtually immune to at least some guns as long for its destruction would take a direct hit at least 305-mm shells of marine instruments, then VD Mendeleev was the first engineer who applied protivosnaryadnoe booking. Running the machine was based on air suspension rollers (on board by 6 rollers of small diameter, 5 and 4 support rails were leading the upper rear wheels), which allowed the car to change the ride height or even fall to the ground with heavy fire in order to avoid running injuries parts. It was also intended to lower the body on the ground to increase the accuracy. VD Mendeleev, taking into account the impressive weight of the machine, anticipating a design chassis can move by rail, install the special tool carts on wheels that can be driven car engine, allowing it to move by rail without the help of others. Landing crew of eight men (commander, mechanical, control, gunner, machine gunner, three gunners) and loading ammunition was carried out through a door located in the rear armor plate.
The machine is also provided for interior lighting on-board power supply. Estimated weight of the machine — 172 tons, with the specific ground pressure less than 2.7 kg/cm2. Design speed — 24 km per hour, with a power carbureted engine with water cooling of 250 horsepower. The engine was placed in the back of the case with a small offset to the left side, with the fuel tanks are in the center hulls, which lacked the capacity of the car to go 50 miles without any additional charge. Tank had a manual gearbox with four-, 4 — go ahead, 1 — back. On the roof of the body was placed spinning retractable machine gun (one 7.62-mm machine gun "Maxim") cylindrical tower with a radial arc of fire, which sank in the stowed position inside the housing. Reservations turret was 8 mm. Drawback of such placement was the presence of dead zones, but the project provides loopholes in the sides of the machine to fire crew members from personal weapons. The main armament — 120mm naval gun Kone — housed in the frontal armor plate, with a rotating armored gun mask, which was one of the main features of the design deflection was 16 °. The shells were submitted on the implement monorail pneumatic, so greatly increasing the rate of fire weapons. Kone Cannon at the time had almost indestructible purposes. By all measures it was a stern and majestic battle machine, which were on the shoulder the most difficult and unsafe combat missions. But the story of this project was completed. Later, in autumn 1916 VD Mendeleev again tried to present already modernized with the introduction of the British battle tank project of his car, but he was not subject to review. This was his project from virtually none.
Although the project remained a non-incarnated in reality, he was a major step in the history of tank development. Neither the project nor its painstaking study not intrigued military, he was not accepted for consideration and was put in a long box, like a lot of other similar projects.
