Improving Vehicle Performance by Aerodynamic Devices in Formula SAE 2009-32-0103
In this study, we have evaluated the performance of undertray and rear wing in formula SAE.
The undertray was adopted to increase the driving force transmission. And in order to further increase the driving force and prevent the car from oversteering in high speed areas, a rear wing was mounted.
Finally, by mounting these aerodynamic devices, driving force increased by 41% (undertray 14%, rear wing 27%) at the speed of 90km/h, and by calculating the value of stability factor measured by cornering power, improvement of the vehicle's oversteering tendency was confirmed.
