Unusual Roscii tanks and the Soviet Union. Tank TG 1931

In the USSR in the late 20-ies of the past century have not yet been fully developed tank building. The base of the Red Army Tank-Automotive troops were machines made under license on the basis of imported samples of light tanks. Management of the country, realizing the urgent need to produce its own machines Russian development, strongly contributed to the promotion of various projects of Russian engineers and designers. Once a year, the Commission considered the UMM RKKA 10's projects, make decisions on the allocation of funds for their tremendous development. One of the principal directions of the Russian tank design was to create a medium tank that can accompany the infantry in the deepest coming, and break the fortified lines of defense. Lack of experience of Russian engineers to create such type of machines has led to the plight of several similar projects, and it was decided to invite and connect to the creation of new models of foreign experts. Since the Soviet Union was invited to Germany engineer Grote Edward (Edward Grote). Once in the Russian Union in March 1930, E. Grote, together with a group of German technicians and engineers already in April, begins working on his new project, maneuverable medium tank TG or "Tank Grote."

Project TG designed specially made KB ABO-5 plant "Bolshevik." The plan E. Grote, according to the teachings of the terms of reference, it should be highly maneuverable, well armed and protected rolled 18-30-mm armor protivosnaryadnoy tank weighing less than 20 tons, capable of traveling at speeds of over 35 km per hour. In April 1931 experienced a standard machine was built and in July was submitted to the tests, which lasted more than 2 months. Showing good results rate of 34 km per hour, the highest agility and continuity, tank Grote through reverse drive and six-speed box had the ability to move forward and backwards with similar speed. Shielded chassis of the car was a huge 5 rubberized rollers diameter, fitted with a personalized spiral spring and brake mechanism. 6 support rollers, guides and rear (with the inside it-gear wheel) on the board. Track shoes were made by the method of hot stamping and had the highest share of strength. The aft hulls was placed V-shaped 12-cylinder aircraft engine M-6 carburetor type rated 305 hp The hulls car was completely welded, size: length 7.5 m, width 3.1 m, height 2.84 m, from rolled armor plates with inclined installation, the armor was: the forehead — 44 mm, side — 24 mm, feed — 20mm.

The layout of arms is a three-tier, the first tier of weaponry consisted of a 2-7.62-mm tank guns DT-29, installed in ball bearings and placed in the side body armor plates. Second tier included 76.2-mm gun collaborative design PN Syachentova and E. Grote and three 7.62-mm machine gun system "Maxim" also set in the ball joints and placed in the highest turret box. Third tier — one 37-mm gun PS-1, installed in a rotating turret, which had a large vertical angle pickup, which allowed for fire at air targets.

To monitor the progress of the battle on the roof of a revolving turret cupola was installed, equipped with a tank periscope.

Overall machine made the right memory to the committee members, but identified a number of significant drawbacks, one of which was a small zabronevoe space, close placement of the crew led to the inability to lead immediately fire the cannons and machine guns. It was noted unsatisfactory cooling motor, causing it to overheat Hassle. , The location of the box and steering clutches made access to these sites for repairs in case of breakdown. October 4 1931 , it was ordered to the profound and comprehensive review of the study, "Grote tank." Carefully examining the car, the Commission concluded: "Tank Grote considered as experimental model. " In general, not only the technical flaws machine served as the reason for refusing to take it on board and start the series. In addition to the rest of the affected design complexity in the production, making the machine very expensive, its price has exceeded 1.5 million rubles. Soon all the work on the project was stopped TG, engineer E. Grote started to develop new projects for the creation of languid tanks TG-4 and TG-5. But the lessons learned Russian engineers and designers worked together with German officers in the upcoming be successfully applied in subsequent projects.
