Lift, in the context of this article, refers to the upward force generated by an aircraft’s wings that enables it to overcome gravity and achieve flight. It is a crucial concept in aviation and is essential for understanding the principles of flight.
Lift is generated when air flows over the wings of an aircraft. The shape of the wings, known as an airfoil, is designed to create a difference in air pressure between the upper and lower surfaces. The higher airspeed over the curved upper surface of the wing results in lower air pressure, while the lower airspeed over the flatter lower surface results in higher air pressure. This pressure difference creates an upward force, known as lift.
