Close out the ends of the rear wing stack and control the flow spilling off the wing tips.
Prevent pressure equalisation around the ends of the elements. Curved endplates and louvres were both identified as open investigations for CR26E: curved endplates to keep out tire wake, louvres to bleed high pressure off the top surface and reduce the pressure gradient.
No part-specific design process is documented. The Rear Wing subsystem design process applies: 1. 2D ANSYS sweeps to optimise element positions and angles of attack for each candidate element count. 2. Verify positions in 3D and increase stack angle of attack where 2D over-predicted. 3. Run integrated half-car runs with the current undertray iteration so element interaction is captured rather than assumed. 4. Full-car yaw runs to check performance when the front stack is reduced. 5. On-track validation with tufting on both surfaces and Flo-Vis oil during constant speed and skid pad.
