Operational Context
Sukhoi Su-31 — single-seat unlimited aerobatic aircraft
The Su-31 was introduced in the early 1990s as a development of the earlier Su-26 aerobatic aircraft. It featured refinements to aerodynamics and structure to enhance performance in unlimited competition. The aircraft employs composite materials and a steel tube fuselage core for strength.
Powered by a Vedeneyev M14P radial engine producing approximately 360 horsepower, the Su-31 is capable of roll rates exceeding 400 degrees per second. Maximum takeoff weight is roughly 2,100 pounds (950 kg). The airframe is stressed for high positive and negative g loads typical of unlimited aerobatics.
The Su-31 has been used in world championships and advanced aerobatic displays. Its combination of power and structural resilience made it competitive at the highest levels. The design remains a prominent example of post-Soviet aerobatic engineering.
