Design of an Aerodynamic Package for FSAE Racing Car and CFD Analysis

In the field of racing cars,air dynamics research has become the focus of competition between the events and teams. For Formula SAE,aerodynamic research is very important.This paper through aerodynamic simulation analysis of G03C racing car,finds out influence aerodynamic factors of the vehicle model,and designs an aerodynamics package for it according to the principle of aerodynamics,including the front wing,rear wing and diffuser. Compared the aerodynamic performance of the car before and after modification,the results show that the increase of pressure makes the car high-speed stability improve under suite aerodynamic package.
