Aerodynamics in FSAE can be used to describe the ineraction 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 (), coefficient of Drag (<meta http-equiv="content-type" content="text/html; charset=utf-8">) and the ratio of <meta http-equiv="content-type" content="text/html; charset=utf-8">.
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 inclues lift and drag coefficents and helps you determine your target goals.
