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.

* Quiet operation with a direct-drive motor and balanced airfoils.
For refinement around the airfoils to capture the turbulence wakes, a sphere of influence was defined at such region.
Features include a smart controller with resistive touchscreen and password protection that controls up to eight fans; eight patented airfoils topped with winglets to eliminate wind noise; an IP43-rated motor and NitroSeal drive gearbox that is fully sealed to resist corrosion and reduce heat buildup for longer life.
When designing the blades, the airfoils are coupled as if they were length differentials ([DELTA]L); these, in turn, decrease in size as they move away from the rotational core.
