Page "Wing" Paragraph 12

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.

The properties of the airflow around any moving object can-in principle-be found by solving the Navier-Stokes equations of fluid dynamics.

However, except for simple geometries these equations are notoriously difficult to solve.

Fortunately, simpler explanations can be described.
