Nikitin NV-6

Vasily Nikitin · Soviet Union · first flew 1940 · fighter

The Nikitin NV-6 (IS-1/IS-2) was a remarkable Soviet experimental fighter concept that could fold its lower wing to convert between biplane and monoplane configurations in flight. Only prototypes were built before the programme ended.

WEFT is AircraftIQ's four-point recognition method — how it works.

Spot it by:

Tiny, compact fighter with a straight mid-set wing, inline engine, and the ability to present either biplane or monoplane profile — unique in aviation history.

History

Vasily Nikitin designed the NV-6 as a way to combine the take-off and climb performance of a biplane with the high-speed performance of a monoplane. The concept called for the lower wing to fold flush with the fuselage once airborne. Limited trials showed the idea was workable but impractical for service use, and the project was abandoned.

Variants

The IS-1 and IS-2 were successive prototypes with different engines; no production series was ordered.

Where you'll see it

Never entered service; expended in experimental trials only.
