Purpose

CR21 assembly line covering the front and rear wings together.

Function

The CR21 cost report did not separate the front and rear wing packages, so both are costed under this one assembly. From CR22 onward they are split into separate Front Wing and Rear Wing assemblies with their own elements, endplates and mounting. This is the clearest of the split-assembly cases the taxonomy README flags. Design Philosophies and Processes: Inherited from the Front wing subsystem design process: 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.

Reoccuring issues

Because the assembly spans two subteam groups, the same assembly name appears under both Front wing and Rear Wing in the taxonomy. Resolve which node owns it before the wiki publishes this page.
