Formula Student race cars are getting more competitive and hence enhancements of the car aerodynamics, although the top speeds are not exceeding 140 km/h, are getting more important in order to have a competitive race car. Therefore aerodynamic packages consisting of several aerodynamic devices are being developed. Especially the front and rear inverted airfoils or wings have a major influence on the dynamic behaviour of the car. These wings are designed in order to develop a maximum down force at still acceptable drag. The Reynolds number is about 5×105. However, most of the airfoils and corresponding available airfoil data were developed for Reynolds numbers of the order of 3×106<Re<8×106. The lift coefficient of an airfoil is basically determined by its camber, the distance of the maximum camber from the leading edge, thickness and the shape of the airfoil, as well as by the angle of attack. The NACA 4 digit series of airfoils allows controlling these parameters exactly. Therefore a study was performed analyzing over 500 different NACA 4 digit airfoils configurations systematically by variation of these parameters and studying its impact on the lift and drag coefficients at Reynolds numbers of 5×105. Based on these airfoils the aerodynamic design process is described. Full car CFD simulations with ANSYS CFX of the race car with and without aerodynamic package are shown and compared. Detailed quantitative analysis of the forces on the wings and the whole car are presented without and with the aerodynamic package.
