Aerodynamics and Structural Design of the Sukhoi Su-31
Aerodynamic Design
The Sukhoi Su-31 is a low-wing monoplane, a design choice that enhances its aerodynamic efficiency during high-speed maneuvers. The aircraft’s wing configuration provides the necessary lift while minimizing drag, allowing for tighter turns and more precise control during aerobatic routines. The wings are relatively short but wide, which contributes to the aircraft’s excellent roll rate of 401 degrees per second. This makes the Su-31 one of the fastest-rolling aerobatic planes in its category.
The wing design also incorporates a symmetrical airfoil, a common feature in aerobatic aircraft. Symmetrical airfoils are ideal for performing inverted flight and vertical maneuvers because they generate equal lift regardless of the aircraft’s orientation. This allows the Su-31 to perform complex stunts such as loops, hammerheads, and knife-edge passes with ease.
Wing Span and Surface Area
The wing span of the Su-31 is 8.2 meters (26.90 feet), which is relatively compact compared to other aerobatic aircraft. The shorter wingspan reduces the moment of inertia about the roll axis, enabling faster roll rates and better control during spins or snap rolls. The compact wings also contribute to the plane’s agility in tight spaces, making it ideal for competitive aerobatics where precision is key.
Another important aspect of the wing design is its surface area, which provides enough lift to maintain controlled flight at both high and low speeds. The combination of a short wingspan and sufficient surface area ensures that the Su-31 can handle a wide range of speeds without sacrificing maneuverability.
Fuselage Design
The fuselage of the Sukhoi Su-31 is constructed from all-metal materials, primarily aluminum alloys, which provide both strength and lightweight characteristics. This construction method ensures that the aircraft can withstand high G-forces without suffering structural damage. The fuselage is designed to be as streamlined as possible, reducing drag and improving overall speed and fuel efficiency.
One of the unique aspects of the Su-31’s fuselage is its ability to endure extreme stress during aerobatic maneuvers. The aircraft’s structure is rated to handle up to +12G and -10G, meaning it can endure forces twelve times greater than gravity without compromising safety or performance. This makes it one of the most durable aerobatic planes available today.
Tail Section
The tail section of the Su-31 features a conventional horizontal stabilizer and vertical fin configuration. The tail height is 2.76 meters (9.06 feet), providing ample control authority during pitch and yaw maneuvers. The elevators and rudder are oversized compared to those on standard aircraft, allowing for more precise control during extreme maneuvers like flat spins or tail slides.
The rudder is particularly important in controlling yaw during knife-edge flight or when recovering from spins. Its large surface area gives pilots greater control over directional stability, even at low speeds or high angles of attack.
Landing Gear
The landing gear on the Sukhoi Su-31 consists of a fixed tricycle configuration with retractable options available on some variants (like the proposed but never fully developed Su-31U). The fixed gear design simplifies maintenance and reduces weight while providing adequate ground clearance for take-offs and landings on various surfaces.
The take-off distance for the Su-31 is relatively short at just 363 meters (1,190 feet), thanks in part to its powerful engine and lightweight design. Similarly, its landing distance is only 300 meters (984 feet), making it suitable for operation from small airstrips or grass fields commonly used in aerobatic competitions.
Cockpit Design
The cockpit of the Sukhoi Su-31 is designed with pilot comfort and visibility in mind. It features a single seat for the pilot, with a large canopy that offers excellent visibility in all directions—an essential feature for aerobatic flying where situational awareness is critical. The canopy is made from lightweight but durable materials that can withstand high G-forces without cracking or distorting.
In terms of instrumentation, the cockpit includes basic avionics necessary for navigation and communication but does not feature advanced systems like autopilot or weather radar—these are unnecessary for an aerobatic plane focused on manual control and performance flying. Instead, the emphasis is on providing clear readouts for speed, altitude, engine performance, and G-forces so that pilots can monitor their aircraft’s status during intense maneuvers.
Control Surfaces
The control surfaces on the Sukhoi Su-31 are oversized compared to those found on traditional light aircraft. This includes larger ailerons for roll control, elevators for pitch control, and a rudder for yaw control. These oversized surfaces allow for more precise handling during complex maneuvers such as rolls, loops, spins, and hammerheads.
The large ailerons contribute significantly to the plane’s impressive roll rate of over 400 degrees per second. This allows pilots to perform rapid rolls with minimal input from the control stick—a crucial factor in competitive aerobatics where precision timing is everything.
Structural Durability
One of the standout features of the Sukhoi Su-31 is its structural durability. Aerobatic flying places enormous stress on an aircraft’s frame due to rapid changes in speed, direction, and altitude—often accompanied by extreme G-forces. To handle these stresses, Sukhoi engineers designed the Su-31 with reinforced spars in both the wings and fuselage.
These reinforcements allow the plane to endure high G-loads without suffering structural damage or deformation—a critical factor when performing advanced stunts like snap rolls or tail slides that place significant strain on an aircraft’s structure.
Additionally, many parts of the plane are designed to be easily replaceable in case of damage during practice sessions or competitions—ensuring that pilots can quickly get back into action after minor mishaps.
Engine Performance
At the heart of every great aerobatic plane lies its engine—and in this regard, the Sukhoi Su-31 does not disappoint. It is powered by a single Vedeneyev M14PF radial piston engine, which produces an impressive 400 horsepower—one of the highest power outputs for an aircraft in this class.
Vedeneyev M14PF Engine
The Vedeneyev M14PF engine is a nine-cylinder radial engine originally developed in Russia for use in both military trainers and civilian sport planes like those produced by Sukhoi. It has become famous among aerobatic pilots worldwide due to its reliability under extreme conditions as well as its ability to deliver consistent power throughout long flights involving multiple complex maneuvers.
This engine uses air cooling rather than liquid cooling systems found on many modern engines—a design choice that reduces weight while providing adequate cooling even during sustained high-power operation at low speeds (such as during vertical climbs).
Engine Specifications:
- Type: Radial piston
- Cylinders: 9
- Displacement: 10 liters
- Maximum Power Output: 400 hp (298 kW)
- Fuel Type: Aviation gasoline
- Fuel Consumption: Approximately 8 gallons per hour at cruise speed
- Weight: 230 kg (507 lbs)
Fuel Efficiency
Despite its powerful engine output, one area where pilots must be mindful when flying long distances with their Sukhoi Su-31s is fuel consumption—especially given that most flights involve periods at full throttle while performing complex stunts requiring maximum thrust output from their engines.
With an average fuel consumption rate around 8 gallons per hour at cruising speeds combined with total onboard fuel capacity limited around 76 gallons (289 liters), pilots typically have enough range (~594 nautical miles) between refueling stops if they maintain moderate throttle settings throughout most portions their journey

Technical Advancements and Modifications of the Sukhoi Su-31
Composite Materials and Weight Reduction
One of the key advancements in the design of the Sukhoi Su-31 is the use of composite materials, particularly in the rear fuselage and wing structures. This innovative approach to construction not only reduces the overall weight of the aircraft but also increases its structural strength and durability. The use of composites allows for a lighter airframe without compromising on the aircraft’s ability to withstand high G-forces, which is crucial for aerobatic performance.
According to reports, the rear fuselage of the Su-31 is made from composite materials, which significantly reduces weight compared to traditional metal constructions. This weight reduction has a direct impact on the aircraft’s performance, allowing for faster acceleration, improved climb rates, and more agile handling during aerobatic routines. The combination of a lightweight airframe with a powerful engine gives the Su-31 an exceptional power-to-weight ratio, making it one of the most competitive aerobatic planes in its class.
In addition to the fuselage, the wings of the Su-31 are also constructed from composite materials. The composite wings are designed to be both lightweight and strong, providing excellent lift while maintaining structural integrity during high-stress maneuvers. The wings are equipped with large ailerons that contribute to the aircraft’s impressive roll rate of 401 degrees per second, allowing pilots to perform rapid rolls with minimal control input.
Fuel System and Range
The fuel system in the Sukhoi Su-31 is another area where significant advancements have been made. The aircraft is equipped with a fuselage tank that holds approximately 70 liters (18.5 gallons) of fuel, which is used primarily for aerobatic flights. This tank provides enough fuel for short-duration flights focused on aerobatic maneuvers, where weight reduction is critical for performance.
However, for longer flights or cross-country travel, the Su-31 can be equipped with additional long-range wing tanks, each holding over 100 liters (26.4 gallons) of fuel. These tanks significantly extend the aircraft’s range, allowing it to cover distances of up to 1,100 kilometers (680 miles) without refueling. While these additional tanks provide greater range, they do come with a weight penalty that can slightly reduce the aircraft’s agility during aerobatics.
Some variants of the Su-31 were produced without these wing tanks, relying solely on fuselage fuel for shorter flights. In these cases, pilots could opt for detachable belly tanks if extended range was needed. This modular approach to fuel storage gives pilots flexibility depending on their mission requirements—whether it’s a short aerobatic display or a longer cross-country flight.
Luggage Compartments
Despite being primarily designed as an aerobatic aircraft, the Sukhoi Su-31 offers an unusual feature for its class: multiple luggage compartments. This makes it somewhat unique among aerobatic planes, which typically prioritize performance over storage capacity.
The Su-31 has three distinct luggage areas:
- A bay behind the pilot: This compartment provides space for personal items or small equipment.
- A separate compartment in front of the pilot, located above the fuselage tank: This area can be used to store additional gear or supplies.
- A compartment in front of the instrument panel: This space is designed to hold a specially-made suitcase that can be quickly installed and removed from the aircraft.
These storage options make the Su-31 more versatile than other aerobatic planes, allowing pilots to carry essential items during cross-country flights or competitions without sacrificing too much performance.
Cockpit Ergonomics and Visibility
The cockpit design of the Sukhoi Su-31 places a strong emphasis on pilot comfort and visibility—two critical factors in competitive aerobatics where situational awareness and precise control are paramount.
The cockpit features a side-opening canopy, which allows pilots to open it while idling on the ground—a useful feature in hot weather conditions when waiting for takeoff clearance. The canopy itself is made from lightweight materials that provide excellent visibility in all directions, giving pilots an unobstructed view of their surroundings during complex maneuvers.
In terms of ergonomics, the cockpit layout is designed to minimize pilot workload during high-stress situations. The controls are arranged within easy reach, allowing pilots to make quick adjustments without losing focus on their flight path. The instrument panel includes essential avionics such as altimeters, airspeed indicators, engine gauges, and G-force meters—all critical for monitoring performance during aerobatic routines.
The Su-31M2 variant, introduced in 1999, further improved cockpit ergonomics by incorporating a larger canopy/windscreen that enhanced visibility even more. This variant also featured weight reductions and other refinements aimed at improving overall handling and performance.
Safety Features
Given its role as an aerobatic aircraft capable of extreme maneuvers, safety is a top priority in the design of the Sukhoi Su-31. One notable safety feature found in some variants (such as the Su-31M) is a pilot extraction system—essentially an emergency ejection seat that allows pilots to safely exit the aircraft in case of catastrophic failure during flight.
This system was developed by Zvezda SKS-94 and is designed specifically for light aircraft like the Su-31. It provides an added layer of protection for pilots who regularly push their planes to their limits during competitions or training sessions.
In addition to this extraction system, all versions of the Su-31 are built with reinforced structures capable of handling extreme G-forces without suffering damage or deformation. This ensures that pilots can perform advanced stunts like snap rolls or tail slides without risking structural failure—a critical consideration when flying at high speeds under intense stress conditions.
Modifications by Richard Goode Aerobatics
Richard Goode Aerobatics has played a significant role in modifying and improving several Sukhoi Su-31s over time. These modifications have included enhancements such as:
- Lighter electrical systems: Replacing heavy Russian electrical components with lighter Western analogues.
- Improved propellers: Installing more efficient propellers that increase thrust while reducing drag.
- Additional wing tanks: Adding long-range wing tanks that more than double fuel capacity.
