Abstract
A fitting assembly includes a fitting with at least one a pocket. The pocket includes a web extending inward from a perimeter of the pocket, and the web has cutout that defines an inner edge. A stiffener is mounted within the pocket. The stiffener includes a lattice and a coupler that is configured to engage at least a portion of the web to mount the lattice to the fitting.
Claims20
An aircraft component, comprising:
- (a) an elongated steel fitting, comprising a plurality of pockets, wherein each pocket has walls surrounding the perimeter of the pocket and a web extending inward from the perimeter of the pocket, the web having an aperture defining an inner edge;
- and
- (b) a stiffener, comprising:
- (i) a lattice having a generally rectangular exterior shape having four straight edges that meet at a rounded corner, wherein the lattice is inserted in the aperture defined by the web;
- and
- (ii) a coupler configured to engage at least a portion of the web, the coupler coupling the lattice to the web,
- (c) wherein a majority of a length of the elongated steel fitting is comprised of the pockets having stiffeners with lattices.
A stiffening insert configured for stiffening an elongated steel fitting having a pocket, wherein the pocket has walls surrounding a perimeter of the pocket and a web extending inward from the perimeter of the pocket, the stiffener, comprising:
- (a) a lattice having a generally rectangular exterior shape having four straight edges that meet at a rounded corner, wherein the lattice is inserted in an aperture defined by the web;
- and
- (a) a coupler associated with the lattice and configured to engage at least a portion of the web.
A fitting assembly, comprising:
- (a) a fitting having first and second surfaces on opposites sides of a thickness of the fitting, the fitting further comprising:
- a first pocket on the first surface, the first pocket has walls surrounding an entire perimeter of the first pocket, and the first pocket has a depth extending partway through the fitting thickness,
- a second pocket symmetrical to the first pocket, wherein the second pocket is on the second surface, the second pocket has walls surrounding an entire perimeter of the second pocket, and the second pocket has a depth extending partway through the fitting thickness, and
- a web extending inward from the surrounding perimeter walls of bottoms of the first and second pockets, wherein the web has a thickness less than the fitting thickness, the web having an aperture defining an inner edge;
- and
- (b) a stiffener, comprising:
- (i) a lattice;
- and
- (ii) a coupler configured to engage at least a portion of the web, the coupler coupling the lattice to the web.
