Abstract

Based on the 2017 Formula Student Electric race car of KMUST, racing team of Kunming University of Science and Technology built entity models by CATIA, designed and optimized the combined wings of the race car spoiler by STAR-CCM+, comparing with the model of leeboards on different "gills" area, "gill" number and notch at the back edge by the Orthogonal experiment. The results show the aerodynamic efficiency of the rear wing is improved obviously through the leeboards modeling optimization, in which the drag coefficient (cd) is reduced by 13.75%; the lift-to-drag ratio is increased by 6.71%.
