Trainer Aircraft

Nikitin

NV-2

One of the most successful was the single-seat trainer aircraft NV-2 he created. This low-wing wooden structure, with a landing gear retractable into fairings under the wing, was built in 1935 mainly by students of the Moscow Aviation Technical School with funds allocated by Osoaviakhim. The NV-2 was flown by many flight instructors from Moscow flying clubs. The aircraft (empty weight 385 kg, take-off - 750 kg) with the M-11 engine developed a speed of up to 230 km / h and climbed to a height of 5800 m.

Like all other planes of V. V. Nikitin, the NV-2 monoplane was distinguished by a good finish and outwardly resembled the I-16 fighter. Its monocoque fuselage was veneered and covered with linen. The wing with an area of ​​11 square meters is one-piece, wooden, sheathed with plywood and also covered with canvas.

The designer then used the successful NV-2 scheme for the NV-2-bis and UTI-5 training aircraft with the MG-31 engine of 300 hp. It should be noted that pilots-instructors of flying clubs took part in the tests of UTI-5.

UTI-5 (NV-2 bis - MG-31) - the same NV-2, but accordingly reinforced for the MG-31 engine. The plane was made very cleanly and better than the serial I-16, to which it was very similar in appearance. It was released by order of the UVVS and tested by pilots of the Air Force Research Institute, Civil Air Fleet and Osoaviakhima (extended factory tests). In total, up to 40 pilots flew on it. It was recognized that the aircraft was good and fit for its purpose as a training fighter, especially since it had a ShKAS synchronous machine gun with 250 rounds. The Air Force ordered a series of 20 aircraft, which was not completed.

NV-6

Trainer Aircraft

NV-6

By the end of the 30s of the last century, the development of aviation had already reached such a level that simple two-seat training vehicles capable of performing a limited number of aerobatic maneuvers were no longer enough for pilot training. There was a need for the so-called training fighters - vehicles designed for practicing aerobatics by young pilots and participating in aviation competitions that were very popular at that time.

The aviation design bureaus of A.S. Yakovlev and V.K. Gribovsky took up the creation of such vehicles. The talented designer Vasily Vasilyevich Nikitin also proposed his own version of such a vehicle. The NV-6 (UTI-6) aircraft was developed at the expense of Osoaviakhim at the Moscow Aviation College.

The vehicle was made according to the scheme of a compact biplane, in which the ailerons were only on the lower wing, and the upper wing was swept (80 degrees along the edge) and slightly exceeded the lower one in scope. The structure is mixed. Fuselage with a frame made of XMA pipes, wings - wood with canvas, plumage - duralumin with canvas. Chassis - cantilever racks with balloon wheels in fairings. The aircraft was built using the central part of the fuselage and the wing from the HB-1, which was included as the lower wing in the biplane box HB-6.

MG-11F engine, 165 hp. had a special carburetor designed by M. A. Kossov for inverted flight. With a takeoff weight of 750 kg, the aircraft had a high power-to-weight ratio sufficient to perform any aerobatics. This was facilitated by a high margin of safety, the maximum operational overload was nine units.

NV-6 was built in OKB-30 in 1939, but there was no engine for it, which was delivered only in December 1940, after which V.V. Nikitin and V.V. Shevchenko carried out a number of test flights. The aircraft showed quite good flight data, however, due to the lack of static tests, TsAGI did not give permission for official flights, and the tests dragged on until the war itself, when it was no longer possible to deal with this very interesting aircraft.

Drawing NV-6

Vasily Vasilyevich Nikitin (1901-1955) worked for more than ten years in the design bureaus of D.P. Grigorovich and N.N. Polikarpov. The accumulated experience later allowed him to create up to a dozen original light aircraft. Without interrupting his main job, he learned to fly and tested almost all of his cars in the air.

During the Great Patriotic War, V.V. Nikitin worked as a chief engineer, then as a chief technologist at aircraft repair enterprises, and in the last years of his life - as deputy chief designer of helicopters, N. I. Kamov.
