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

A wing flap includes a flap body and a torque member. The torque member is integrally formed with at least a portion of the flap body.

Wing flap with torque member and method for forming thereof

A wing flap includes a flap body. The flap body includes an upper skin, a lower skin opposite the upper skin, and a plurality of spars that extend between the upper skin and the lower skin. The wing flap also includes a torque member that is coupled to the flap body. A portion of the torque member is contiguous with at least one of the upper skin and the lower skin.

A torque tube door and related method steps may include a door coupled to an inboard wing flap, such that the door is movable with the flap to selectively cover and uncover a torque tube opening in an aircraft fuselage.
