An airfoil coupling system includes plural airfoil coupling structures, each of which includes a body having a horizontal flange with a first coupling interface that is coupled with panels of an airfoil of an aircraft. The first coupling interface extends between first and second ends in a first direction, and between third and fourth ends in a second direction. The body also includes a vertical flange having a mating end that is coupled with the horizontal flange. The vertical flange includes a second coupling interface that is coupled with a rib of the airfoil. The second coupling interface extends between fifth and sixth ends in the second direction, and between mating and free ends in a third direction. Each of the airfoil coupling structures are disposed at different locations along a length of the rib between a leading edge and a trailing edge of the rib.

Airfoil coupling systems and methods

Aircraft main landing gear drag brace backup fitting assemblies and related methods are described herein. An example aircraft wing disclosed herein includes a rear spar having a rear side and a front side opposite the rear side, a side-of-body rib coupled to the rear spar, a rib post disposed on the front side of the rear spar, where the rib post is to couple a second rib to the rear spar, a side-of-body fitting coupled to the side-of-body rib, an intercostal member coupled between the side-of-body fitting and the rib post, and a drag brace fitting disposed on the rear side of the rear spar. The drag brace fitting is coupled to the rib post and the side-of-body fitting via a first plurality of fasteners extending through the rear spar.
