A structure with a curved surface designed to give the most favorable ratio of lift to drag in flight, commonly used in aircraft wings, propeller blades, and rotor blades.

The engineers tested the new aerofoil design in the wind tunnel to ensure it would improve the aircraft's performance.

The cross-sectional shape or profile of an aerofoil structure.

The designer adjusted the aerofoil to achieve a higher lift coefficient.

aerofoiladjective

Relating to, characteristic of, or functioning as an aerofoil.

The aerofoil section of the rotor blade was redesigned for efficiency.
