4. Air actions on the vehicle

This section is dedicated to the action of air on the vehicle, in other words, to automotive aerodynamics. However, the aim is not to give a course in fluid dynamics, but rather to provide information on the essential data involved in vehicle dynamics, what form they take and how they can be used in the context we are concerned with. To fully understand how these data are used, we refer to the basic results developed for aerodynamics in aeronautics, which are the subject of the 4.1 paragraph; the 4.2...
