Right Front Wing End Plate

Subteam: AerodynamicsSubsystem: Front wingAssembly: Front WingCars: CR22, CR25, CR26I, CR26E

Purpose

Mirror of the left front wing endplate.

Function

Identical function, mirrored geometry. See the left endplate entry for the sweep data that justifies the fence and half-tube.

Design Process

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.

Manufacturing Process

Waterjet from sheet, or laid up on a milled or 3D printed mold.

Full Material List

Same laminate schedule as the left endplate.
