F-6 (ANT-7) - a multi-purpose Soviet aircraft, which had the following destination options: scout bomber, torpedo, triple fighter.


In the middle of 20-ies it became a popular theory about the need to position a part of the military forces of long-distance fighters to infiltrate deep behind enemy lines.

Slightly reworked TB-1 design and comes with its engines BMW-IV, was able to reduce the size and weight of the aircraft. The speed of the aircraft was about the same as that of the single-engine biplanes of the time. The first prototype was built in September 1929, at a trial only began in May 1930-th after the modifications of the aircraft. State flight tests began in October 1931 years. Successfully completing them, to establish serial production model.

The first batch was released in Moscow at the plant № 22. Coming up with 1932 of serial production moved to the plant in Taganrog number 31. Since 1934 in Moscow again resumed serial production under the designation KR-6. Production was up to 1935 years, and for all time built around aircraft F-400 6 in different versions.

Design F-6 (ANT-7)

F-6 - cantilever monoplane, having composed two engines. Power plants with rotors were right and the left fuselage, the front wing. This aerodynamic design, which was first proposed in the Tupolev R-6, soon became known as a classic for the majority of combat aircraft of that time.

The fuselage is mainly made of chain mail. The airframe is made of corrugated sheets. Its thickness is from 0,3 to 0,8 mm. The wing included a centroplane, made in unity with the central part of the fuselage, and two detachable consoles. The composition of the longitudinal set of the wing included stringers and four spars. The latter consisted of dense, flat tubular trusses that moved in the direction of the wing into beams with tubular shelves and stamped walls. Shelves made from docked chain mail aluminum pipes, which have a different cross-section. The closing of the joints of the corrugated skin was ensured by the U-shaped profiles, which were placed along the ribs.

On the wing ailerons installed large, which consisted of tubular kolchugalyuminievyh spars and cladding of corrugated sheets. The ailerons had aerodynamic compensator large and small aerodynamic axial compensation. wing profile was very thick and designed Tupolev team specifically for heavy aircraft.

The structure of the fuselage consisted of three parts: the nose, middle and tail. Their matchmaking took place on the bolts. The fuselage has a truss, which riveted kolchugalyuminievymi pipes, lining - made of thin corrugated sheet. Forward fuselage occupied cabin that housed the shooter observer. It was adopted in the form of a turret machine gun, then located the cockpit.

The middle part of the fuselage occupied turning "knife-like 'sliding down machine-gun installation. On top of the tail section placed another machine gun turret.

The design of the tail was like a wing. Podnosny stabilizer served rocker aircraft in various flight conditions could change its position, rejecting at 5 degrees in both directions. This was made possible with the use of a screw jack mechanism, which has been linked with a steering wheel cockpit cable runs.

As part of the power plant had two engines with water cooling type and wooden propellers fixed pitch. Engine mounts were made of steel and all metal pipes were attached to the wing center section with four bolts. Under the engine nacelles were placed in water radiators. Fuel tanks riveted construction were made from kolchugalyuminiya. They have set on the wing tool trays, fixation was performed by metal tie bands.

Chassis in F-6 aircraft pyramidal, non-retractable, made of steel pipes. Swivel has riveted kolchugalyuminievy crutch. Depreciation crutch corded and chassis, rubber. In winter time skiing instead of the chassis installed. In some versions of the aircraft floats put TB-1. Modification of the MR-5 widely used for civilian and military purposes.

Russia and the World Combat Aircraft

Confidence AN Tupolev in choosing for themselves the goal of a lifetime - the creation of a long-range heavy aircraft - causes all respect and admiration for him as a person and designer. ANT-7 was another, albeit small, step towards achieving a dream.
Andrei planned to create a fighter. Installation of two motors power of 500 hp. Already allowed to compete in speed with light single fighters. However, at the top they wanted to see a car designed for a five-seater crew carrying reinforced weapons and capable of performing the functions of a long-range fighter, as well as a reconnaissance aircraft for flights to the enemy's deep rear. The increase in the weight of the load reduced the speed by one and a half times, the main emphasis in aerial combat was not on the ability to maneuver, but on firepower. This completely neutralized Tupolev's original idea, moreover, all the weighting was accounted for already designed and partially in the production design. Only the weight was reduced by the crew of 4 people.
During the tests the aircraft F-6 has received a lot of comments. One of the most serious was the tail buffeting. Rectification took a lot of time, reducing the length of stay morally ustareyuscheymashiny in military units. After decommissioning the aircraft served in the civil airlines, as well as the training.

What it shows me that you - Sanya - not seven found there. Firstly, as far as I know, they do not fly there, and secondly, it is probably a modification of an entirely different plane. Perhaps, not even our own, and the Germans. They have a lot of these were.

Incidentally, intelligent "air cruiser". The first successful model that combines aviation and naval forces. Roughly speaking was born in the Soviet Navy. I still like that in this plane, he was tenacious. Quite a few of them were shot down. Also inspires a large number of modifications created.

There is interesting information. My colleagues and I recently discovered fragments of an incomprehensible aircraft in the Crimean mountains, or rather, at first we thought that it was an incomprehensible flying machine, but later on, Zhenya (my friend) suggested that this was a model of Tupolev. Toli civilian ANT-7, felts combat intelligence R-6. When we found it, there was a downpour, so it was not possible to consider everything ideally. It is interesting that the found remains of the engine M-17 with the factory number 2-1060. Painted in green and blue color pieces of plating - corrugated aluminum. In general, the rest will be viewed in the next "expedition"
