The individual bracket parts that make up the front wing mounting.
Take load from the wing hardpoints into the frame tabs, in double shear where possible.
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.
Milled rather than waterjet from CR26I onward, because the waterjet cut surface leaves stress raisers that can propagate.
