Abstract
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.
Claims20
An apparatus, comprising:
- a hinge pin to rotatably couple a foldable tip of an aircraft wing to a fixed structure of the aircraft wing, the hinge pin including 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.
An apparatus, comprising:
- a hinge pin joint including a foldable tip of an aircraft wing, a fixed structure of the aircraft wing, and a hinge pin, the hinge pin rotatably coupling the foldable tip to the fixed structure, the hinge pin including 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.
A foldable aircraft wing, comprising:
- a foldable tip;
- a fixed structure;
- and
- a hinge pin rotatably coupling the foldable tip to the fixed structure, the hinge pin including 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.
1 more element
A method, comprising:
- moving a foldable tip of an aircraft wing between a folded position and an unfolded position relative to a fixed structure of the aircraft wing, the aircraft wing including a hinge pin rotatably coupling the foldable tip to the fixed structure, the hinge pin including 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.
