1. a structure with a curved surface designed to give lift when moving through air, such as an aircraft wing
Usage: British spelling; American equivalent is ‘airfoil’

Examples

• The aircraft’s aerofoil design allows it to generate lift during flight.
• Engineers tested the new aerofoil shape in a wind tunnel.
• The helicopter’s rotor blades have an aerofoil cross-section.
• Birds’ wings naturally form an aerofoil shape when extended.
• The racing car’s rear wing uses an inverted aerofoil to create downforce.
• Students learned how air flows over an aerofoil in physics class.
