Aerodynamic Basics

Aerodynamics in FSAE can be used to describe the interaction of air and the racecar, in particular its bodywork and aerodynamic elements such as wings, diffusers and fins. It can be analysed by the use of Computational Fluid Dynamics. The performance of aerodynamic elements can be described by parameters such as the coefficient of Lift ($C_{l}$), coefficient of Drag ($C_{d}$) and the ratio of $C_{l}/C_{d}$.

Conceptual aspect of Aerodynamics

Aerodynamics is not necessary to make a car go around a racetrack. Check beforehand if your car benefits from aerodynamic elements. Simple laptime simulation usually includes lift and drag coefficents and helps you determine your target goals.
