Introduction to Airfoil Aerodynamics

This is part 5 in a series of fundamental aircraft design articles that aims to give you an introduction to aircraft design principles. In a previous post we looked at the importance of the shape and plan-form of the wing, and how this has a great impact on the flying characteristics of the aircraft. Specifically we looked at wing area and aspect ratio. In this post we look more closely at the shape of the wing airfoil: why this differs from aircraft to aircraft, and how a careful airfoil selection will help to produce the flying characteristics you desire for your airplane.
