The Tupolev ANT-1 ( Russian Туполев АНТ-1 ) is the first aircraft built by Tupolev in the 1920s, an experimental single - seat low -wing aircraft with a radial engine . The ANT-1 was intended as a light sports aircraft, but was mainly used to test the relatively new material aluminum in aircraft construction. The first flight took place on October 20, 1923.
development
The aircraft was equipped with an Anzani radial engine with 35 hp and could fly a maximum of 120 km / h. The wingspan was 7.5 meters and the curb weight was only 205 kilograms.
In 1920, aviation officials from the Soviet Union, which was just being formed, commissioned various scientists to find a light and hard aluminum alloy suitable for aircraft construction. In 1922 the first results were available in the form of the “Kolchugalumin” alloy (named after the place of manufacture Kolchugino ). It was decided to use this material in the construction of the ANT-1 developed under the direction of Andrei Tupolev from the summer of 1922.
The aircraft had a wooden frame fuselage with mostly fabric covering, the aluminum was used for the wings, the tail unit ribs and for the planking of the front and top of the fuselage. That was about 60% of the plane.
After the maiden flight, the pilots N. I. Petrow and E. I. Pogossi alternately completed several successful test flights. However, testing was stopped when the only available Anzani engine failed and was irreparably damaged. There are contradicting statements about the whereabouts of the aircraft. The aircraft manufacturer Tupolev itself claims that it was destroyed in 1937, other sources claim that the aircraft was on display in a museum until at least 1941.
The successor, the Tupolev ANT-2 , was made entirely of aluminum and is considered to be one of the first “real” aluminum aircraft in the world.
