NIAI OSh

The Osh was an attack aircraft designed in the USSR from 1939.

Development

In 1930, the LIIPS formed a UK GVF, a training centre for civil air fleet. In turn, the UK GVF formed the NIAI which became the focus of several good design engineers who were given command of individual OKB.
In 1939, Anatolii Georgievich Bedunkovich designed a large single-engined twin-boomed attack aircraft, it was to be constructed from stressed skin light-alloy. This large aircraft was to carry a heavy cannon armament including a turret in the rear of the fuselage nacelle, which also housed the single engine, driving propellers in the nose of each tail-boom, through shafts and gearboxes. There is no record of this interesting project having been built or flown.
