Since the wing exerts a force on the air to change its direction, the air must also exert an equal and opposite force on the wing. When this occurs, the wing deflects the airflow downwards as it passes the wing. įor a wing to produce lift, it must be oriented at a suitable angle of attack. However, except for simple geometries these equations are notoriously difficult to solve and simpler equations are used. In principle, the properties of the airflow around any moving object can be found by solving the Navier-Stokes equations of fluid dynamics. ![]() The design and analysis of the wings of aircraft is one of the principal applications of the science of aerodynamics, which is a branch of fluid mechanics.
