Rear Wing Endplate Brackets

Subteam: AerodynamicsSubsystem: Rear WingAssembly: Rear WingCars: CR22, CR25, CR26I, CR26E

Purpose

Attach the endplates to the element stack.

Function

Carry the endplate load into the airfoil spars.

Design Process

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.

Manufacturing Process

Milled. Mounting parts moved from waterjet to milled because the waterjet cut surface leaves stress raisers that can propagate.

Full Material List

Aluminium.
