ANT-46 (CI-8)

In the design office of Tupolev, an experienced ANT-46 type fighter was designed, which was supposed to work at long distances. This machine was designed in parallel with the aircraft ANT-40, but, in contrast, it was a triple, equipped with both offensive and defensive weapons.

This aircraft was designed to cover bombers and was equipped with more powerful engines than the previous version of the ANT.

In the development of this aircraft designers was taken into account a number of nuances, they encountered in the manufacture of previous devices. Therefore, it was designed quickly and accurately. It had an all-metal body design, which has been perfectly worked on other planes, manufactured Tupolev. Also, the aircraft had a water-cooled engine that distinguishes it from other cars of the time. It was equipped with two large-caliber guns, which could produce 15 volleys. These guns were installed on the wings.

Its first flight ANT-made 46 35 in the middle of summer, after which he was transferred to the Commission for the passage of factory tests. But soon the work on the machine have been stopped due to the emergence of new at that time rockets such as MS. It is for this reason that the designers had to change weapons to a new and effective.

Designers OKB installed on this aircraft four cannons brand SHVAK, which were placed in the wing. A version of the aircraft with the same guns was developed, but under the fuselage of the apparatus, and their number was increased to five. The ventral version was more convenient for replacing and charging guns. In addition to weapons, aerodynamic qualities were also improved by equipping the wing with a detachable part. Also, the horizontal tail was changed, and a horn compensation system was added to the tail steering wheel during the flight. There was a thought of replacing engines with newer AM-34. But a year after this, this project was completely closed.

Design features ANT-46

The design of the machine is made of duralumin. plane body is composed of three structural parts, which are manufactured separately and linked to one another. The front part of the aircraft structure is represented by the cockpit, which has a large glass area. The cockpit gets via the hatch in the bottom, was made through him, and the emergency evacuation of the crew.

Middle compartment of the aircraft was manufactured together with the wings, namely the assembly of wings takes the most amount of time and materials. This compartment housed the post of the machine's control, namely the cockpit. Cabs pilot and radio operator were equipped otdvizhnymi lanterns, lantern and radio operator had a large size. At the tail section of the tail unit was attached.

As for the power plant of the aircraft ANT-46, it is significantly different from previous models because it was represented by two engines of the type K-14. They had both the designation - "Mistral-Major." They were given power 800 horsepower each and were air cooled. The engines were installed in front of center on special motor farms. For optimum performance, between the motor has been installed a ring-type oil cooler. Engines with their work resulted in the movement of the screws that were made of wood and had a diameter of 3,4 meters.

airframe was made of tubular metal sections, which have V-shaped. They are mounted on the casing of the machine itself and thus creating a closed circuit. The designs were frames and ribs, which were made of duralumin and had holes, due to which the design has been reduced weight unit.
