The aircraft Tupolev ANT-2. A photo. History. Characteristics.
ANT-2 - metal aircraft, which has a corrugated siding kolchugalyuminiya. It is a monoplane with a triangular in cross-section fuselage and cantilever high-wing, which made it possible to abandon the spacers and increase rigidity. ANT-2 had a booth of closed type for two passengers, with a seating area, located opposite each other. Through a side door you can log on to the cabin. The aircraft was equipped with a motor Bristol Lucifer (three cylinder) capacity in liters 100. from.
Along with the work on the aircraft ANT-1 preparing the material base for the construction of domestic all-metal airplanes.
Production of semi-finished kolchugalyuminiya (corrugated, sheet metal, pipes, profiles, rivets) allowed the team, which was headed by AN Tupolev, begin to build an all-metal aircraft.
In May 1923 years for the construction of aircraft, the Commission embarked on a UWS order to create a single-engine aircraft in two versions: as a spy plane with a machine gun and a passenger, is designed to carry two or three passengers. For ANT-2 picked scheme cantilever all-metal monoplane having a wing verhneraspolozhennoe.
ANT-2 was completed in May 1924 years 26 and May this year, NI Petrov first took it up into the sky. Until April 1925 years passed the test aircraft. According to their results, it was decided to release a series of five machines. This task fell to workshops Kolchugino. ANT-2bis had 200 hp engine and it was designed to carry three people. Due to work load Bureau to deploy a series of P-3 (ANT-3) implement plans to release 5 ANT-2bis worked. Only in 1930 was established one machine ANT-2bis. However, it was not possible to implement the project reconnaissance, built on the base ANT-2. Preserved today ANT-2 can be viewed at the Museum of the Air Force, located in Monino.
The design of ANT-2
As already mentioned, the plane was completely made of kolchugalyuminiya (height - 8 mm pitch - 40 mm). When you create a special attention was paid to good aerodynamic quality, simplicity of design, reduced weight without compromising strength.
The wing of a continuous, rigid, two-spar, with twenty-six truss ribs, with a bow-type ANT-2, which has a relative thickness in sixteen percent. By the fuselage wing spar is secured by four bolts on top. In front of the wing, which hangs over the cockpit, there is a cut-out. Below on the wing tips are provided a small bow, by which the movement is directed AN-2 aerodrome. Moreover, the bow were mounted on the aircraft parking area.
The fuselage has a triangular shape, which provides good stiffness with minimum weight, as no longer necessary in the struts and braces when mounting frames. Fuselage trehlonzheronny. Motor roofing is attached to the front of the four bolts. When removing the two bolts with it it can rotate simultaneously with the motor, just as in the doors on the hinges.
an open cabin and is located above the engine. Small celluloid visor protects the pilot from the air stream (later increased it). On the dashboard are instruments showing speed, altitude, the presence of gasoline, engine speed, temperature and oil pressure. The pilot climbs into the cockpit on the left, where there is a special recess for the legs.
The passenger cabin in the normal version is designed for two people and is located above the cockpit. From the aft fuselage and cockpit separated its corrugated walls. The front door is located in front of the cockpit on the port side. On each side is made of 3 window. The passengers sat facing each other on the woven reed chairs. Passenger seat located behind the cockpit, did not have a back.
The chassis is attached to the bottom of the fuselage. It is with 2 poluoski with stretch marks, which were enclosed in a little lower plane, located between the wheels.
