For Airfoil we have terms and definitions in 3 topics. The topics are Explosives, Import Cars and Wind Energy.

A surface designed to develop a desired force by reaction with a fluid, especially air, that is flowing across the surface. Examples of airfoils are the fixed wings of airplanes, which produce lift ( aerodynamics), and control surfaces, such as ailerons, elevators, rudders, and flaps, that are manipulated to produce variable forces. Other airfoils include spoilers, propeller blades, and the blades utilized in turbojet engines.

An aerodynamic device designed to improve traction by increasing the downforce on the car. The use of airfoils (also called wings) increases the cornering capability and improves stability at speed, but often at the expense of additional aerodynamic drag.

The cross section profile of the leeward side of a wind generator blade. Designed to give low drag and good lift. Also found on an airplane wing.
