The aircraft Tupolev ANT-40. A photo. History. Nature of.
ANT-40 is a high-speed bomber. Mass production aircraft, the development of which is owned by CB AN Tupolev.
7 1934 October, the ANT-40 made its first flight under the control of the pilot KK Popov. 1936, the spring has been released the first production aircraft. Over the years, series-built aircraft repeatedly modernized. In 1941 year prior to the termination of serial release was issued more than 6 thousand. Aircraft of various modifications.
1931 autumn, the first flight made a new all-metal twin-engine bomber, which was created by a team of designers AA Archangel, who worked under the direction of A. Tupolev.
Flight tactical and external forms of the new aircraft, known as the Security Council, namely the high-speed bomber, testified to the success of the designers and aircraft in addressing the fundamental problem, which has been put before the Soviet air force in those years: fly faster, higher, farther.
Speed AN-40 (SB) was 1,5 times the speed of serial bombers TV-3. AN-40 has a smooth lining. Rational pair wing and well streamlined fuselage, a fully retractable landing gear isolated new bomber among modern similar machines with the same purpose. Takeoff weight AN-40 - 5706 kg empty - 4138 kg.
The first copy of AN-40 was equipped with air-cooled radial engine (M-25) in 730 hp In another instance of engines installed M-100, which were only recently mastered and took power in 760 hp Flight tests of these options were at the same time. They demonstrated that more promising is the bomber engine M-100.
The maximum speed of the car at the height of 4 thousand. M higher than 420 km per hour. As you can see, it was higher than that of foreign aircraft in the same class. This version of the aircraft was used as a basis for the preparation of aircraft production, which became known as SB-2.
Designers AH-20 never ceased to improve aircraft. Over time, it appeared more powerful engines, such as M-100A, M-103, M-105, which had a screw variable pitch in flight. It also strengthens the on-board weapons.
As a result of improvements to the complex maximum speed of the aircraft increased to 450 km per hour. Such fighting qualities of the new Soviet bomber in 1937, the learned in Europe. Spain, to purchase aircraft AN-20, was satisfied, as they have shown themselves in the great battles.
On one of the upgraded SAT-2 test pilot MU Alekseev was able to break the world altitude record with a cargo of 1 tons. The aircraft climbed with this weight by height in meters 12 246.
In addition to the bombers, it was issued a certain number of airplanes in the postal and cargo version. They received the following notation - SS-40. The pilots of "Aeroflot" on these machines first mastered flying at high altitudes.
ANT-40 produced at two factories in the Soviet Union and four in Czechoslovakia. According to official data just released 6831 aircraft of various modifications. As already mentioned, in the process of production of the aircraft was constantly improved. Also, the planes were in service in Czechoslovakia and China. In Spain, the ANT-40 has received the designation "Katya" (in honor of the heroine of the popular at the time of the operetta "Bombardier Katya").
The first combat use occurred in October 28 1936 year, whereas the four SAT struck the airfield at Tablada (near Seville). For a long time they were almost invulnerable to the Italian and German fighters. Security was also used against the Japanese in China, Khalkhin-, Hassan and the Finnish war. In the days of the Great Patriotic War planes were already considered obsolete.
