Improving the aerodynamic characteristics of racing cars is one of the important means to improve the performance of FSAE.This paper completed the FSAE car body and aerodynamics device design and development, based on the CFD technology in the car’s aerodynamic characteristics are studied.Through the analysis of the aerodynamic characteristics of the car body with and without aerodynamic devices, and the comparative analysis of airflow pressure and velocity distribution around the car body and aerodynamic devices, the simulation results show that the aerodynamic devices effectively improve the aerodynamic characteristics of the car, and better improve the control stability and driving safety of the car.

Recently reduce in fuel consumption and concern regarding the ground vehicle safety, automotive engineers are faced with the immediate task of introducing more efficient aerodynamic performance vehicles. Hence, the rear spoiler attached on the ground vehicle was presented. Rear spoiler is a device commonly found on road vehicle for improving their aerodynamic performance. Review on the research effects of the rear spoiler aerodynamic analysis on ground vehicle performance is reported in this paper. This review intends to enhance the stability and safety by attaching the rear spoiler on ground vehicle. The review mainly focus on aerodynamic analysis and control of the rear spoiler for different types ground vehicle in term of improving vehicle performance. Researches carried out by a number of researchers with regard to analyze and control the rear spoiler of ground vehicle and their effect on ground vehicle performance. Aerodynamic analysis i.e. computational fluid dynamics(CFD), design optimization, drag coefficient (Cd ) and lift coefficient (Cl ) and control methods i.e. passive control and active control had been reviewed. Meanwhile, progressive research on the rear spoiler aerodynamic analysis was observed due to its flexibility for wide range of application in the different type vehicles.
