Formula Student SC19 New Front Wing & Sidepods Aero Package · 模型 5624
This project documents the design and development of a new aerodynamic package for the SC19 racecar, adapted for autonomous operation. The work focused on the front wing, sidepods, and supporting aerodynamic devices, replacing the previous configuration with a more efficient and better-controlled flow structure. The update began with a full reconstruction of the inherited car CAD assembly, which required reorganising parts, correcting geometry, and restoring surface quality before any new aero surfaces could be developed. The new front wing was then modelled from a clean sheet, using a multi-element layout sized to increase the available planform area and improve circulation in ground effect. Small vortex-control devices were added on the suction region to improve boundary-layer behaviour across steering-angle and ride-height variations. The endplate and footplate geometry were revised to better manage the wheel wake and condition the flow toward the underfloor and sidepods. The central section was kept geometrically cleaner to limit interference with the cooling inlets. Additional 3D-printed whiskers were integrated to control the upwash generated by the front wing and to stabilise the tyre-wake region, improving the downstream flow feeding both the sidepods and the rear wing. The sidepods retain the overall shape of the original configuration, but the trailing-edge and endplate regions were redesigned to strengthen floor-edge vortex sealing and reduce cross-flow into the diffuser inlet. These changes produce a more stable flow field in yaw and reduce local induced drag. Overall, the combined package increases front-axle downforce with only a moderate drag penalty, resulting in a more favourable aerodynamic balance and improved performance under operating conditions. Development relied on parametric surfacing, iterative CAD refinement, and in-depth CFD analysis employed to assess both local changes (pressure distribution, endplate loading) and global flow conditioning toward the underfloor. Internal structural layout, attachment strategy, and composite stacking-sequence considerations were also assessed through preliminary FEA to verify stiffness, load paths, and manufacturability. This work was carried out during my time as part of the Chassis & Aerodynamics Division of Squadra Corse DRIVERLESS | PoliTO (Sep. 2024 – Feb. 2025).
