2019 Cooper Motorsports FSAE Aerodynamics

Over the course of the 2019 FSAE season I developed a specialized aerodynamics package through CFD analysis, wind tunnel testing, and on track testing. The package consists of an extreme outwash front wing, four element rear wing with a leading edge slat, an aerodynamically efficient Venturi tunnel undertray, a drag reducing engine shroud, and aerodynamically beneficial sidepods for improved cooling and aerodynamic performance. The CFD models were tuned using wind tunnel data. The components in the package were iterated through CFD by using Altair Hypermesh for controlled mesh generation, Ansys Fluent for simulation, and CFD-Post for post processing. The package was designed to work cohesively to maximize downforce and minimize drag, resulting in a downforce to drag ratio of 3.0.
