The Sukhoi Su-31 is a Russian aerobatic aircraft powered by a single engine, created by Sukhoi as a lighter and higher-performance evolution of the Sukhoi Su-29.

Design and development

Development began in 1991 to produce a single-seat variant derived from the earlier Sukhoi Su-29, equipped with a more robust Vedeneyev M14PF engine and redesigned landing gear. This low-wing cantilever monoplane completed its maiden flight in June 1992 under the designation Su-29T, with serial production models taking to the skies starting in 1994.
