Foldable aircraft wings are disclosed. An example aircraft includes a foldable wing having a fixed wing portion, a foldable wing portion and a hinge to pivotally couple the foldable wing portion relative to the fixed wing portion. The hinge includes a wing transition portion including wing hinge ribs and wing stub ribs, respective ones of the wing hinge ribs coupled to corresponding respective ones of the wing stub ribs. The hinge also includes a tip transition portion including tip hinge ribs, where respective ends of the tip hinge ribs positioned between corresponding respective ones of the wing hinge ribs and the wing stub ribs.

Foldable aircraft wings

A folding wing hinge for a wing having a fixed wing portion and a folding wing portion, the folding wing hinge including a hinge pin including a hinge pin spline and having a first longitudinal axis, an input fitting coupled to one of the fixed wing portion and the folding wing portion, the input fitting including an input fitting spline and a second longitudinal axis, and a spline coupling member having a coupling spline configured to couple with the hinge pin spline and the input fitting spline so that the first longitudinal axis moves relative to the second longitudinal axis by a first predetermined amount of movement.

Folding wing hinge, aircraft and method therefor

Hinge pins for foldable aircraft wings are described. An example apparatus includes a hinge pin to rotatably couple a foldable tip of an aircraft wing to a fixed structure of the aircraft wing. The hinge pin includes a first flange, a second flange spaced apart from the first flange along a central axis of the hinge pin, and a through hole oriented along the central axis.
