Why Airbus gave its A350 distinctive curved wingtips

Guillaume Faury, CEO | Airbus

Airbus designed the A350 with integrated, curved wingtips to improve aerodynamic performance and efficiency. The wingtips are not simply an aesthetic choice; they are blended into the wing structure to reduce vortex drag, which occurs when high- and low-pressure air meet at the wingtip. By minimizing this drag, airlines operating the A350 benefit from lower fuel consumption and reduced environmental impact.

Aviation Partners, a company known for its work on wingtip technology, has explained that these features allow for optimal "aerodynamic loading" and help "avoid vortex concentrations that produce drag." This results in less fuel burn and allows aircraft to fly further on the same amount of fuel. While many modern jets use winglets or wingtips, the A350’s curved design also enables greater wing flex. This means the wings can adapt automatically to changes in air pressure during flight, contributing to more efficient operation.

The concept of flexible wings is now standard in commercial aviation. Aircraft must withstand significant vertical G-forces as required by FAA and EASA regulations. During testing of other widebody jets like the Boeing 777X, engineers have simulated extreme loads where wings bend significantly without structural failure. Flexibility helps dissipate energy safely rather than transferring stress onto other parts of the aircraft.

The A350's airframe uses advanced materials—up to 54% composites along with titanium and advanced alloys—and features a four-panel fuselage design that optimizes strength while minimizing weight. According to Airbus, these choices were made with environmental sustainability and efficiency in mind. The design also includes technologies such as Variable Camber (VC) and Differential Flaps Settings (DFS), allowing pilots to optimize wing shape during flight for better lift-to-drag ratios.

Powering the A350 is the Rolls-Royce Trent XWB engine, developed using data from 70 million hours of Trent family service. Airbus claims it is currently “the world’s most efficient aero engine in service.” The engine was specifically created for use on this model.

Over time, Airbus has introduced incremental improvements to the A350’s wingtips. In 2017, new taller and squarer wingtips were added to enhance span load distribution and reduce drag even further. These changes improved fuel efficiency and range; most new A350s produced since then feature this updated design. However, earlier deliveries—including those operated by Qatar Airways, Vietnam Airlines, Finnair, Delta Air Lines, and Singapore Airlines—still have older winglet versions.

The success of these blended curved wingtips influenced later Airbus models such as the A330neo. When developing this aircraft, designers incorporated similar large curved wingtips into an extended outer span section of the wing—a change that increased overall wingspan but did not increase drag thanks to aerodynamic refinements like those used on the A350. Other enhancements included using carbon fiber-reinforced plastic (CFRP) for part of the structure and optimizing components through computational fluid dynamics modeling.

According to FlightGlobal reporting (https://www.flightglobal.com/airframers/a330neos-wing-changes-deliver-fuel-burn-gain/128890.article), these advancements led to a roughly 4% improvement in fuel efficiency for the A330neo compared with previous models.

Winglets have become common since their introduction on business jets in 1977. Manufacturers continue experimenting with different shapes; while Boeing’s latest designs are also blended into their wings—as seen on the 737 MAX—they do not curve upward in quite the same way as Airbus’ recent models.

Francois Obe, marketing director for the A350 program at Airbus, commented on updates: “With the aircraft being better than we have expected in service… we will be able to deliver some of [the new developments] in 2018...We needed to be sure the aircraft structure was good enough to sustain the additional weight, and it is the case."

As airlines seek ever-greater efficiency from their fleets amid rising costs and environmental concerns, innovations like those found on Airbus’ latest widebodies may become increasingly standard across commercial aviation.
