This paper explains how plane designers improve the fuel economy of planes by improving the wing airfoils. This article describes three stages of wing airfoil designs. They are periods: the period between World War One and World War Two, the 1980s, and 2000s. Every time stage there is a specific kind of airfoil design to reduce the air resistance and improve fuel economy. In the end, it also gives some suggestions about future airfoil designs to improve the future fuel economy of planes.
