Also found in: Thesaurus, Medical, Encyclopedia, Wikipedia.
A part or surface, such as a wing, propeller blade, or rudder, that interacts with a flow of air to provide stability, rotation, lift, or thrust.
(Aeronautics) US and Canadian a cross section of an aileron, wing, tailplane, or rotor blade. Also called: aerofoil
any surface, as a wing or stabilizer, designed to aid in lifting or controlling an aircraft by making use of the air currents through which it moves.
A part, such as an aircraft wing, designed to provide lift as air flows around its surface. Air passes over the airfoil faster than it passes beneath it, resulting in greater pressure below than above. Propellers are airfoils that are spun rapidly to provide propulsion.
