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.

As first a movement of a body (ship) in a water was studies, it is not a surprise that some aviation terms are the same as naval ones rudder, water line, – keel beam, speed measured in knots (nautical miles). It is further influenced by the development in professional motorsport, which decreases the variety of designs. 198 0 obj<>stream Vehicle aerodynamics includes three interacting flow fields: • flow past vehicle body • flow past vehicle components (wheels, heat exchanger, brakes, windshield), • flow in passenger compartment.

Pietro Fittipaldi announced as Grosjean's replacement for Sakhir GP . The time schedule is tight and the knowledge is limited in most cases. Clearly the modified formula does an excellent job. 0000002158 00000 n 0000013743 00000 n 164 35 Rev. In Aerodynamics class, one learns that wing lift depends on the air density, the speed at which it is traveling, its size, its shape, and its angle of attack. 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. 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.
