摘要： A device includes a drive link coupled to an actuator and a first link coupled to the drive link, the first link and the drive link forming a first pivot point. The device also includes a second link coupled to the first link and a support shaft coupled to second link. The second link and the first link form a second pivot point and the second link is configured to rotate about the support shaft. The device further includes a third link coupled to the second link and includes a fourth link coupled to third link and coupled to a door assembly. The third link and the second link form a third pivot point, and the fourth link and the third link form a fourth pivot point. When the door assembly is in an open position, the support shaft, the third pivot point, and the fourth pivot point are aligned.

摘要： Disclosed herein is a seal assembly for sealing a gap between a first component and a second component is disclosed. The second component is movable relative to the first component. The seal assembly includes a rub strip and a seal strip. The rub strip includes a seal strip engagement surface having a convex shape. Additionally, the rub strip includes a first component engagement surface that is opposite the seal strip engagement surface and has a concave shape. The seal strip includes a rub strip engagement surface having a convex shape. Furthermore, the seal strip includes a second component engagement surface that is opposite the rub strip engagement surface and has a concave shape. The seal strip engagement surface is harder than the rub strip engagement surface.

摘要： 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.
