The Nikitin NV-5, was a tandem-seat trainer aircraft designed and produced in the USSR from 1934.

Development[]

In 1934 (Society for assistance to aviation and chemical industry), and (Aviation Department of Vnito, all union scientific and technical research organisation), opened a competition for designing and building a safe aeroplane. Nikitin designed a small biplane with tandem seating, I-type wide chord struts, rubber shock-isolating engine mounts and small semi-balloon tyres. The fuselage was built up from welded steel tubing with plywood covering and the wings were constructed from wood with fabric covering. The first prototype had a Licence-built Renault MV-4 inverted in-line engine, but later variants used M-11 or MG-11 radial engines.

The NV-5 won the Osavaiakhim/ AVIAVnito competition in 1937 and was prepared for production, as the U-5, for Osaviakhim and UVVS. One U-5 was modified with a ShKAS machine gun under the starboard wing and four under-wing RS-82 rockets.

The most significant variant of the U-5 was the LSh (Legkii Shtabno – light staff aircraft), built in 1942 at the request of the , this aircraft was used operationally on liaison and special missions from Leningrad to the Caucasus mountains. With a much more powerful MG-31F engine, Polikarpov I-153 upper wing, enclosed cabin, toughened rear cockpit with bench seating for two and aluminium lining, the LSh had excellent STOL and range performance.
