air·foil

 (âr′foil′)
n.
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.

airfoil

(ˈɛəˌfɔɪl)
n
(Aeronautics) US and Canadian a cross section of an aileron, wing, tailplane, or rotor blade. Also called: aerofoil

air•foil

(ˈɛərˌfɔɪl)

n.
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.
[1920–25]

air·foil

(âr′foil′)
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.

For example, one might want to predict the performance of an airfoil (or even design an airfoil from first principles) given known uncertainties in angle of attack, air speed, environmental conditions and design imperfections without having to resort to extensive and repetitive testing.

Their goal: to tuna the aluminum into an airfoil or wings to be attached to a piece of foam to test in flight.
However, the working Reynolds numbers of small-power wind driven generators are relatively low and the air viscosity has relatively great influence on paddles, so the use of traditional airfoil is difficult to work efficiently in such bad conditions (Michael et al.
