Aerodynamic Study of the Different Spoiler Section Design used in Formula-SAE Cars 2021-28-0181

Aerodynamics of a car plays a very important role in a racing car. That is why many race cars are designed to take advantage of aerodynamics. Improvement of cornering speed in the race car is achieved through increase in the downforce on the tire. Spoilers (inverted wings) are used for increasing the downforce but this increases the drag too. The performance of a racing car depends on both the downforce and the drag, requiring good compromise between these two forces. In this paper, different airfoils which are used for building the front and rear spoiler of the race car are analyzed. NACA 0012 is analyzed at 0° angle of attack. The front spoiler design is made on the basis of the result with the analysis of S1223 (s1223-il) and GOE304 at 10° and 17°. Modeling of a wing has been done in Solid work and CFD analysis using ANSYS software.
