Composite FSAE Aerodynamic Kit
The Goal
Model, Simulate, and Manufacture a Composite Aerodynamic Kit for the HR26 FSAE Race Car
Aerodynamic Kit Components
Wings
Wings were selected to generate bulk downforce due to high lift coefficient compared to other aerodynamic devices, especially at lower speeds. Constructed with a carbon fiber layup over a foam core with carbon rods and aluminum spars.
Bodywork
Bodywork was designed, simulated, and constructed to minimize drag and cover the new ECU and exhaust introduced with the HR26 FSAE race car platform.
Cooling
Cooling issues with the HR25 platform were addressed with a new radiator inlet, which minimized flow separation and internal drag through CFD & CAD iteration.
The Result
Shock potentiometer and strain gauge data showed aerodynamic loads within 13% of the forces predicted by CFD simulations, indicating strong agreement between simulation and real-world performance. Driver feedback also reported improved drivability and steering balance with the wings installed. Flow visualization using yarn further confirmed airflow behavior consistent with the CFD results.
