Abstract
The objective of this research is to design a set of front and rear wings that can help maximize the down-force to enhance the aerodynamic performance of 2011 Jilin University Formula SAE racing car in dynamic events. In this research, computational fluid dynamics analysis is used for the design of the front and rear wings. Based on a given vehicle body styling, twenty sets of front wing and rear wing profile are investigated, the influence of the endplate shape on the wing aerodynamic performance is also investigated, and one plan was chosen as final design, which is suitable for the vehicle at a relatively low speed (70km/h). The CFD analysis results show that the suitable front wing and rear wing will enhance the aerodynamic performance of the racing car significantly.
