VVA-1 by V.S.Pyshnov


Light biplane, built under terms proclaimed by 1934 Safe Light Aircraft Contest, organized by Osoaviakhim. Designer of VVA-1 was V.S.Pyshnov, professor of the VVA. Tailplane was moved forward as an anti-spin effort. Upper wing carried slatted flaps and ailerons, lower wing - landing flaps. Wings cold be 'folded' backwards for storage or transportation.

All-wooden aircraft had very good airdynamic, but for 100hp engine it was overweight by 100...120kg. Climb and ceiling were insufficient, and VVA-1 was abandoned. This was very unfortunate, because with more powerful M-11E this sturdy biplane could be suitable for production and service.
