Sukhoi Su-42 / Su-26


The first prototype flew on June 30, 1984, and at the World Aerobatic Competitions in Hungary 1984 western pilots saw, for the first time, the replacement for the very competitive Yak 50 and Yak 55; the standard competition aircraft of the Soviet pilots. This was the Sukhoi Su26 (originally called the Su42). The two new aircraft were prototypes with wings and tail made of foam covered plywood and apparently not well finished. They weren't highly placed and did little to impress. It wasn't until 1986 at the world championships in England that the western world saw for the first time the redeveloped Su26M when three aircraft arrived in tight formation. The Su26M had carbon fibre and keviar technology with extensive use of titanium in the spar and landing gear, as well as a longer wing. It was to become the standard aircraft for the Soviet team and very quickly impressed all who saw it in action. The engine never changed and is the same nine cylinder Vedenyev M-14P 360HP engine as in the Yak 55.

A mid-wing, aerobatic taildragger, the fuselage is made of stainless steel tube and kevlar, the wings are composite and the landing gear is titanium. The main spars are a combination of carbon fibre covered with kevlar (ultimate strength +- 28g).

With the political changes that have occurred, the former Soviets have found an increasing desire to attract, sales abroad. The former Soviet pilots soon came to the conclusion that there was a requirement for a two seat aircraft with the same performance as the single seat, principally for training purposes; a point not lost on the Sukhoi design team. Hence the development of the two seat Su29.
