An aerofoil is shaped so that air flows faster over the top than under the bottom. There is, therefore, a greater pressure below the aerofoil than above it. This difference in pressure produces the lift.
The lift generated by a wing is based on the principle that the pressure in a fluid decreases as its velocity increases (Bernoulli′s Principle):
Movable control surfaces, usually mounted in the trailing edge of a wing adjacent to the wingtips, to control an aircraft′s rolling movements.
The curvature, convex or concave, of an airfoil surface.
The distance measured from the leading-to trailing-edge of an airfoil.
The edge of an airfoil which first meets the airstream in normal flight.
The rear edge of an aerofoil.
