Stock material for the endcaps that close out the ends of each wing airfoil.
Endcaps seal the internal volume of each airfoil and provide the bonding surface between skin and endplate.
No part-specific design process is documented. The Front wing subsystem design process applies: 1. 2D CFD sweeps in ANSYS to place elements and set angle of attack cheaply. CR26E ran 153 two-element and 148 three-element sweeps for the rear wing on the same method. 2. Move promising 2D results into a 3D half-car model at 35 mph, chosen as a representative competition corner speed. 3. Iterate in the half-car model, tracking CLA, CDA, CoP and tire drag in an iteration tracker. 4. Run the best candidates in the performance map (PMAP) full-car model for yaw, roll and cornering. 5. Validate on track with constant-speed testing, tufting and Flo-Vis oil.
Endcaps are manufactured independently from the skins and spars, then bonded using 3D printed jigging.
