Abstract
Changes in the performance of a 1/10 scale radio-controlled car due to various mechanical and aerodynamic modifications were investigated. The car’s mechanical performance was evaluated by measuring lap times on custom figure-eight and oval tracks to assess handling. A straight 60-foot track was used to measure acceleration times. Mechanical modifications included a low-center-of-gravity chassis, a higher power motor, and wider street tires to optimize suspension, drivetrain, and grip. Aerodynamic enhancements included the integration of front and rear spoilers, a diffuser, and an undertray all designed using Autodesk Fusion. All aerodynamic components were 3D printed and mounted to the vehicle for physical testing. These components were analyzed using computational fluid dynamics to determine drag and lift coefficients. Computational fluid dynamics results were compared to force measurements made on the car in a crude wind tunnel using a leaf blower. The final car configuration yielded significant improvements in aerodynamic efficiency, increased downforce, and reductions in both lap and 60-foot acceleration times.
