Word forms: (regular plural) airfoils
( Automotive engineering : Vehicle components , Bodywork, controls, and accessories )
is a flat shape such as a wing that is intended
to produce a particular effect from the flow of air.

As air flows over an airfoil wing it is forced downwards, which creates an upward force on the wing.
