Sukhoi Su-26

The Sukhoi Su‑26 is a single‑seat aerobatic aircraft developed by the Sukhoi Design Bureau in the early 1980s to replace the aging Su‑15 series used by Soviet sport pilots. First flying in 1983, the Su‑26 entered production in 1985 and quickly became the benchmark for competition aerobatics, earning multiple world championship titles. Its airframe is a compact, all‑metal monocoque with a low‑wing configuration that provides excellent roll rate and structural rigidity. Power is supplied by a 268‑kilowatt (360 hp) Ivchenko AI‑14R‑25 radial engine driving a two‑bladed propeller, delivering a thrust‑to‑weight ratio favorable for rapid vertical maneuvers. The aircraft incorporates a fully spring‑loaded control system, large ailerons, and a tricycle landing gear with reinforced shock absorbers, allowing pilots to execute extreme loops, rolls, and hammerheads with precision. The Su‑26’s design philosophy emphasized lightweight construction, high power output, and responsive handling, influencing later aerobatic types such as the Extra 300 and the Yak‑55. Its dominance in international contests during the 1990s cemented its reputation as a cornerstone of modern aerobatics and a testament to Sukhoi’s versatility beyond fighter production. Today the aircraft remains popular among civilian aerobatic clubs and is frequently displayed at air shows worldwide.
