The new McFarlane stiffeners are accurately shaped to the same angle that the top and bottom skins come together to completely eliminate the bending stress due to riveting the skins together. This prevents stress concentrations in the skin corrugations and near the rivets, making cracks less likely. McFarlane has improved the stiffener angle as compared to other brands of triangle stiffeners.
The new McFarlane design smoothly transitions from the skin surface to a blunt trailing edge. It maintains the flap’s natural airfoil shape by eliminating the unsightly bulb and resultant drag found on common trailing edge stiffeners.
