View Notes - Aerodynamics_formula.pdf from AA 7311 at National Cheng Kung University. 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. Within Formula 1, aerodynamics is renowned to be highly important. Fluid Mech. Hence … Aerodynamics_formula.pdf - Aerodynamics report The difference between 2D&3D wing symmetry airfoil 2D-Airfoil cambered airfoil Analysis elliptical lift, is the fundamental equation for thin airfoil theory. 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. Aerodynamics is the study of the dynamics of gases, or the interaction between moving object and atmosphere causing an airflow around a body. trailer F1 Firsts: Aerodynamic wings.

In order to improve their stability and handling, engineers mounted inverted wings profiles1 generating negative lift. 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.
