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, and 26 May of the same year, N.I. Petrov first climbed up into the sky. Until April 1925, the aircraft was tested. According to their results, it was decided to release a series of five cars. This task was at the workshops Kolchuginsky plant. The ANT-2bis aircraft had an engine in 200 hp. And was designed to carry three people. Due to the loading of the KB by the works on the deployment of the P-3 series (ANT-3), it was not possible to implement plans for the release of 5 ANT-2bis. And only in 1930 one machine ANT-2bis was created. At the same time, the project of a scout built on the basis of ANT-2 was not realized. The ANT-2 that has survived to date can be seen in the Air Museum, 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.

Design approach А.N. Tupolev was always based on the connection of scientific theory with practice, on the broad adoption of advanced ideas and technologies from related industries. Without this, Andrei Nikolaevich would never become a pioneer in the field of domestic "metal" aircraft construction. Having worked on its first ANT-1 aircraft, the use of new material in separate parts and assemblies, the designer creates an all-metal high-altitude ANT-2 with corrugated embroidery. This was a great success, confirming the prospects of the chosen direction. ANT-2 was designed to carry two passengers or perform reconnaissance flights. Test flights confirmed that the aircraft is extremely light, rational and in no way inferior to Junkers machines, in the design of which duralumin was used, somewhat different in properties from the Soviet analogue. The aerobatic qualities of the aircraft with the modified tail unit did not cause any complaints. Installation of the engine with increased power allowed to increase the passenger load of ANT-2 to three people. It was assumed that the aircraft would be produced serially, however, the difficulties with the supply of imported engines, the lack of production capacities and new, far-reaching plans to create the following all-metal aircraft did not allow them to be realized.

Delusional plane. Delusional test. Information about it, do not understand what it is. Nightmare. I modeller with experience, I have my own collection, but its principle will not simulate.
The maximum ceiling and did not find out, the information about the speed exactly the same, even on the wiki read that if the passenger was sitting two passengers, the plane had one indicator, and if three, then quite different. Such a feeling that it was not designed and was "muddied" like water. The couple quickly welded, interrupted, glued, looked in the face, in the profile. They even more quickly carried out inspections and tests. Eventually. The device seems to be good, but it will not work. All right, bye. I do not like such planes. An air vehicle must be created long, hard and easy. I've often met such things as if things were not going well, the problems started. The case must be changed. Or approach to it to change. And ANT-2 is a direct proof of such problems.

Eugene, they really had five. However, only two raised to the sky. Others simply have built solutions for the "top". When considering all of the aircraft Commission recognized that good, but no one wanted to spend time and energy on the ANT-2. It seems like due to the fact that the projects were already more new aircraft.

I have long been interested in, any information about the mass production of the "carcasses". On the Internet, as well as on the official website of the EDB, almost nothing there. Especially when it comes to the number of cars built. Some sources mention one instance, in the other a few. I do not remember exactly where, like a book on the designer himself and his work, but met 5 number (serial). At the same site EDO is a question of five planned. I understand only one finished. He was the prototype. It's good that it could recover after a fire.
If anyone has what information plz share. It is also not very clear for whom the planned flight. According to one source for domestic airlines, according to another Red Army Air Force. If there is anyone what infa manual, respectful request - to share.
Once I met about the existence of the Old books on ANT and ANT-1-2. Somewhere in the net, you can find it. But there is nothing about the operation.
