Airfoil
An airfoil is a shape designed to produce lift when air flows over it. In aviation, airfoils are used on wings, propellers, and rotors of aircraft to generate lift and thrust. The shape of an airfoil is curved on the top and flat on the bottom, which creates a difference in air pressure between the two surfaces. This pressure difference results in lift, which allows an aircraft to stay aloft. The angle of attack, or the angle at which the airfoil meets the oncoming air, also affects the amount of lift generated. Airfoils are an essential component of aircraft design and are carefully engineered to provide the necessary lift and control for safe and efficient flight.
