Abstract
A self-aligning support incorporates a support attachment fitting and a rotatable pin assembly having a primary load pin coupling the support attachment fitting to an attachment support, and inboard and outboard attachment claws engaged to end portions of the primary load pin. The rotatable pin assembly is configured to rotate relative to the support attachment fitting. At least one fuse pin extends through the primary load pin to limit translation of the primary load pin relative to the inboard and outboard claws.
Claims20
A self-aligning support comprising:
- a support attachment fitting;
- a rotatable pin assembly having
- a primary load pin coupling the support attachment fitting to an attachment support, and
- inboard and outboard attachment claws engaged to opposite end portions of the primary load pin, the rotatable pin assembly configured to rotate relative to the support attachment fitting;
- and
- at least one frangible fuse pin extending through the primary load pin to limit translation of the primary load pin relative to the inboard and outboard claws.
A self-aligning support comprising:
- a support attachment fitting;
- a rotatable pin assembly having
- a primary load pin coupling the support attachment fitting to an attachment support, and
- inboard and outboard attachment claws engaged to end portions of the primary load pin, the rotatable pin assembly configured to rotate relative to the support attachment fitting, wherein the inboard and outboard attachment claws each have a support stud received in a bushing in apertures in an inboard fitting extension and an outboard fitting extension to rotatably support the pin assembly for rotation relative to the support attachment fitting;
- and
- at least one fuse pin extending through the primary load pin to limit translation of the primary load pin relative to the inboard and outboard claws.
A method for fusing of shear out loading on a flap support attachment fitting and accommodating variation in load direction, said method comprising:
- reacting operating loads on a flap with a primary load pin coupling an attachment support to a flap support attachment fitting with inboard and outboard attachment claws, wherein the inboard and outboard attachment claws each have a support stud received in a bushing in apertures in an inboard fitting extension and an outboard fitting extension to rotatably support a pin assembly for rotation relative to the support attachment fitting;
- rotating the pin assembly with an axis of the primary load pin eccentric from a rotational axis of the inboard and outboard attachment claws to accommodate variation in load direction;
- and
- reacting flap deployment loads induced on the primary load pin with at least one fuse pin extending through the primary load pin to limit translation of the primary load pin relative to the flap support attachment fitting.
