Abstract:
The negative lift generated by the aerodynamics package plays an important role in improving the track performance of the Formula One racing. The rear wing is one of the main components that generate negative lift. In this paper, Computational Fluid Dynamics(CFD) technology is used to study the aerodynamic characteristics of the rear wing of formula racing car for college students. The results show that the value of negative lift generated by the empennage increases with the increase of the angle of attack of the main wing in a certain range. The external factors affecting the negative lift of the tail in the Formula SAE vehicle flow field are mainly the body blockage and the upstream airflow of the front wing. The maximum negative lift loss is about 40%; designing different main wing angles of attack for the tail sub-region can effectively improve the ability of the Formula SAE tail to produce negative lift.
