Forces on an Airplane in Flight
... Most airplane wings have a special, basic shape as viewed edge-on: their upper surfaces are curved and their lower surfaces are flatter. This shape is what works with the fluid motion of the air to create lift. As air moves around a wing, some goes over the top and some goes underneath. The air that ...

Aileron

An aileron (French for 'little wing') is a hinged flight control surface usually forming part of the trailing edge of each wing of a fixed-wing aircraft. Ailerons are used in pairs to control the aircraft in roll (or movement around the aircraft's longitudinal axis), which normally results in a change in flight path due to the tilting of the lift vector. Movement around this axis is called 'rolling' or 'banking'.The aileron was first patented by the British scientist and inventor Matthew Piers Watt Boulton in 1868, based on his 1864 paper On Aërial Locomotion. Even though there was extensive prior art in the 19th century for the aileron and its functional analog, wing warping, in 1906 the United States granted an expansive patent to the Wright Brothers of Dayton, Ohio for the invention of a system of aerodynamic control that manipulated an airplane's control surfaces. Considerable litigation ensued with the United States over the legal issues of lateral roll control, until World War I which compelled the U.S. Government to legislate a legal resolution.
