WILLIAMS AIMING TO REDUCE DRAG
Free practice for the Canadian Grand Prix saw Williams sample a new nose with straighter mounting pillars, while the FW38 rear wing also featured additional openings on the endplates.
The zones on each side of the endplate have different pressures: high on the inside, lower on the outside. The horizontal louvres allow the high-pressure air through the endplate and towards the low-pressure area.
This helps decrease the pressure differential, which in turn weakens the vortex generated at the joint area of the endplate and wing tip (see the yellow whirl) with the ultimate goal of reducing drag.
