Binghamton's Formula Society of Automotive Engineers (FSAE) designed an aerodynamically efficient rear wing with three airfoils for their new electric vehicle (EV) to improve lap time. They used an integral model, JavaFoil, to determine the size and configuration of each airfoil. Over 4,000 simulations were conducted to determine the optimal spacing and angle of attack for each airfoil to achieve the best downforce. The results were confirmed through computational fluid dynamics (CFD) simulations and experiments at the AEROLAB Wind Tunnel. The final configuration was manufactured using a manual wet layup technique for epoxy resin and carbon fiber. The rear wing assembly will be installed on the 2023 FSAE EV vehicle, which will compete in June 2023 at the Michigan International Speedway. The findings and insights gained from this project will not only assist future aerodynamics teams at Binghamton Motorsports but will also benefit other FSAE teams.
