CR26E naming for the rear wing endplates.
Same function as the CR22 through CR26I rear endplates.
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.
Infused in a tooling board mold milled on the 5-axis gantry, or laid up on a 3D printed mold for smaller parts. Endcaps, spars and skins are made independently and bonded in 3D printed jigs with glass alignment beads controlling bond gap.
CFRP skins over a wet laid-up spar, with Nomex honeycomb core in sandwich panels.
