Aside from the first two chapters, we are following a sequence of topics that is quite traditional—except for the lack of mathematics—in the multitude of texts discussing fluid mechanics, the basis of aerodynamics. In this chapter we will close our discussion of the underlying science of flight. We have already seen that fluid mechanics teaches the behavior of fluids—liquids and gases—at rest and in motion. Only after mastering these fundamentals, albeit here without the use of higher mathematics, can we begin to understand aerodynamic drag and lift and what makes airplanes fly.
