Airbus Tests Folding Wings for Next-Generation Narrowbody Aircraft

What we know

At the Farnborough Air Show (southwest of London), Airbus announced on July 21, 2026 that it will test folding wing extensions for the next generation of its best-selling aircraft, according to The Guardian. The announcement was made by Sue Partridge, head of Airbus's "Wing of Tomorrow" program—a research and development initiative dedicated to designing wings for the company's next-generation commercial aircraft.

Four- to 5-meter extensions will be fitted to the wings of an A321neo—a stretched version of the A320 family, a single-aisle, twin-engine aircraft—to test different shapes in real-world conditions. Testing will begin in the second half of 2027.

Assembly of these extensions will start at the Airbus facility in Broughton, northern Wales. This initial phase will include only fastening bolts: the hinges allowing the wingtips to actually fold will not yet be integrated.

The final shape of Airbus's next narrowbody aircraft must be determined by 2030. The new generation will use relatively large-diameter, heavy engines and gull-wing-shaped wings.

Context — Longer wings, airport constraints

Longer, thinner wings made of composite materials reduce aerodynamic drag and thus fuel consumption. However, their span can exceed limits allowed at many congested airports. Folding wingtips—which extend during flight and retract on the ground—are being considered as a solution to reconcile aerodynamic performance with airport constraints.

Boeing is the only manufacturer to have equipped a commercial airliner with folding wingtips so far, on its 777X, a large twin-aisle aircraft. If Airbus applies this technology to a narrowbody aircraft, it would be a world first in this segment—the largest sector of commercial aviation.

Boeing is also exploring a "truss" system to structurally strengthen the longer wings of its own future aircraft.
