In order to improve their stability and handling, engineers mounted inverted wings profiles1 generating negative lift. 1 Introduction First racing cars were primarily designed to achieve high top speeds and the main goal was to minimize the air drag. The time schedule is tight and the knowledge is limited in most cases. The constant struggle between the regu- lators and the constructors’ desire for speed pushes the frontier of science and reveals new physics, which deserves the rigor of an academic examination.

To anyone involved in aeronautics, Formula I cars must seem to be pretty weird devices and so, in order to explain some of the rather unorthodox aspects of FI aerodynamic design, I shall start by retracing the history of aerodynamics in FI a few years to 1968, when it was realised that greater gains could be made by increasing the tyre loads than by trying to reduce the drag. 0000002682 00000 n 0 Aerodynamics, from Greek ἀήρ aero (air) + δυναμική (dynamics), is the study of motion of air, particularly when affected by a solid object, such as an airplane wing. 0000009903 00000 n Introduction to Aerodynamics Dr. Guven Aerospace Engineer (P.hD) Aerodynamic Forces •All aerodynamic forces are generated wither through pressure distribution or a shear stress distribution on a body.
