Abstract
Optimizing the design of the aerodynamic packages can effectively improve the performance of the formula SAE (FSAE) racing car.Following the rules of Formula Student China,we take the lead in using the curved wings to optimize the front wing and rear wing for Chongqing University formula SAE racing car.Profili and Xfoil are used to choose the wing sections and optimize the attack angles.An in-depth study is undertaken to analyze the flow field around the formula car in the rectangular parallelepiped wind tunnel simulation via numerical simulations (CFD,computational fluid dynamics).The results indicate that downforce is increased with a sword cured front wing and a rear wing.The rear wing contains a main straight wing and upwarp flap.The downforce coefficient is improved to 1.68 and downforce-drag ratio is improved to 1.91.关键词
