The wind tunnel blade () is formed in a resin transfer molding process in which central, fore, and aft foam core sections () are placed together to form the wind tunnel blade (). Radius fillers () are used to fill the gaps between the outer edge of the foam core sections.

A tip () is formed separately from the rest of the wind tunnel blade () and is glued to the top thereof. Stacked layers of braided fibers () are used to reinforce the central core section ().
