How to Make Planes Fly Faster with the Area Rule

Engineers use a simple mathematical rule about engine placement to design airplanes to be faster and more efficient. Called the area-rule, it defines the ideal cross-sectional area distribution of jet planes. This rule is the reasoning behind why most jet engines on passenger planes are placed slightly ahead of the wings, it all has to do with cross-sectional area. The short video below goes into greater detail concerning this interesting mathematical model.
