General Characteristics

The Sukhoi Su-26M is a single-seat, single-engine aerobatic aircraft derived from the original Su-26. It is one of the world’s premier unlimited-class aerobatic competitors, known for its extremely light weight, high power-to-weight ratio, and robust structure capable of withstanding severe g-forces.

Property	Value (Su-26M)
Rolle	Unlimited Aerobatic Competition Aircraft
Producent	Sukhoi Design Bureau / MAPO
First Flight (Su-26)	Juni 1984
Besætning	1 pilot
Konfiguration	Mid-wing monoplane, conventional fixed gear
Empty Weight	700 kg (1,540 lb)

Design and Powerplant

Engine: One Vedeneyev M-14P 9-cylinder, air-cooled radial piston engine.
Power Output: 268 kW (360 hp).
Propeller: Three-bladed (later four-bladed) German Mühlbauer composite propeller.
Construction: The Su-26 was the first Soviet aerobatic aircraft to use over 50% composite materials, resulting in a very high strength-to-weight ratio.
Fuselage: Steel tube truss structure, titanium in critical areas.
Cockpit: Bubble canopy provides excellent all-around visibility, crucial for aerobatic competition.

Performance and Handling

Maximum Speed: 450 km/h (280 mph).
Stall Speed: 105 km/h (65 mph).
Roll Rate: Extremely high, exceeding 360 degrees per second.
G-Force Limits: Certified for maximum load factors of +12 to -10g, allowing for extremely violent maneuvers typical in international unlimited aerobatics.
Key Improvement (Su-26M): The “M” variant introduced structural enhancements, redesigned wingtips, lighter materials, and often a four-bladed propeller, further enhancing its vertical performance and roll authority.
Competition Success: The Su-26 family won numerous gold medals at World and European Aerobatic Championships, demonstrating superior performance against its Western counterparts.
