And Tupolev-8 (ANT-13). Photo. Story. Characteristics.


And-8, or ANT-13, was an unusual project for KB AN Tupolev. Project ANT-12 (previous model) was not entirely successful, and it will all work to a halt, but the engineer Rodionov still insisted on the construction of a new model based on the fighter failed. Moreover, the work had to be done in your spare time. After the revolution, such events are accepted. Because of this, sometimes in the CB and-8 called "public aircraft". Also for this reason, the plane did not hit the building plan.

Since December 29 years UWS TTT issued to aircraft with flight-technical and technological requirements. Management of the technical plan Tupolev gave P. Sukhoi.

And Tupolev-8

Fighter created in AGOS TsAGI, he belonged to the category of "jockey." "Jockeys" played the role of defense surround important objects. And-8 on technical and flight characteristics had to be agile and climb, which in turn allowed him to make a quick impression interception purposes and to dogfight by quick and short attacks. The maneuverability of the aircraft used lightning allowed to go out of the enemy's attack and quickly rebuilt, once again engage in battle.

Advanced tactical and technical requirements for the ANT-13:

  • 1) maximum speed at an altitude of five kilometers - 310 km / h;
  • 2) maximum ceiling - 8500 m;
  • 3) climb in 5000 m should not exceed seven minutes.

These requirements are approved in January 1930 years.

On the future of fighter history is silent because there is virtually no data left. Among the information found only managed to find two pictures and documents on the history of creation.

In addition to the requirements for the design of an interceptor fighter, I-8 also represented an experimental model. For the first time in the history of Soviet aircraft construction, stainless steel was used in the design. Among the engines engineers chose "Curtiss Concourer" with the permissible power of 600 hp. But with the calculations made, flight performance was reduced. The flying weight of the fighter is 1375 kg, the maximum speed with this weight and with the Curtiss engine was only 281 km / h, and at an altitude of five kilometers it did not exceed 6 250 km / h. Also, the ceiling decreased - 6700 m. The maximum time allowed for climbing in 5 km was 13,1 minutes.

Due to the deterioration of the chief engineer decided to examine the possibility of increasing the degree of compression pressure in the engine. Power should grow 75 hp and speed - on 12-15 km / h. Planned installation of a supercharger (impeller). Among the options considered the best was the last: the speed at an altitude of 3,6 km - 313 km / h on 5 km - 303 km / h, the maximum attainable ceiling - 9000 m. The maximum time to climb to five thousand meters was supposed to be not more than eight minutes.

In the absence of another motor and a built-8 Curtiss V-1570 Conqueror. The aircraft structure used different materials. Wings set up of a metal frame with fabric covering, made of steel belts braces wing box, stainless steel shelves 2A allowed to spar, respectively, ribs made from kolchugalyuminievyh profiles. The documents have not indicated what exactly constructed from the fuselage of the aircraft, but it is known that it could be carbon or chrome-molybdenum tubing. Plumage made from kolchugalyuminiya.

Construction of the I-8 ended in mid-November 1930, and the first flight, made by test pilot M. Gromov, occurred 12 December of the same year. The weight of the aircraft increased and amounted to 1424 kg, because of which the maximum time taken for lifting to the altitude of 5 km increased to 10,32 minutes. After some time the plane was altered. The upgrade plan included established stabilizer control circuits, an oil cooler was enlarged and a crutch control mechanism was mounted. In addition, it was calculated to use an engine with ethylene glycol cooling and supercharging, change the profile of the wings, change the compensating return of the horizontal tail, install the cook on the screw and the closed fairings on the lantern and the chassis.

In August of the following year on a fighter changed the engine, the chassis and the horizontal tail. It was suggested to start flight tests. Thus, the lapping of the aircraft was carried out before the year 32, but the plane in the series and did not because of the reluctance to purchase motors "Konkveror" and similar engines for the replacement was not.

Most of the aircraft I like the fact that it is not big, but compact. It is run by only one pilot.
Also, I really like the fact that he can fly 5 8 kilometers per minute. This excellent performance, because the 1930 year was not enough of these aircraft as fast.
I believe that a great fighter, for 1930-1932 years. The only pity is that in 1932 shut down its production.

The fighter's dream at the time. "Jockey" could give many odds. But imported engine stopped doing so, and turned down the project. And the information about the use unlikely to meet somewhere. The project covered the documents were lost or something. He flew all the nearly two hours.

Hello! I wanted to ask, and if any information about ANT-13. This refers not to the original model, namely-8 and replaced with a motor. I'm aware of what were the requirements for the aircraft and how it was originally. But I do not own nor any infoy about future state tests. He passed them or not. What fate befell him. If anyone there on this topic please write.
