FUEL DAMS, AIRCRAFT WING BOXES, AIRCRAFT, AND METHODS OF ASSEMBLING AIRCRAFT WINGS

Methods of assembling an aircraft wing includes adhering fuel dams to stringers and adhering the fuel dams to ribs. Fuel dams include a fuel-dam body that defines a channel shaped to receive a portion of a stringer of an aircraft wing. The fuel-dam body includes a stringer adherent surface, a rib adherent surface, and a pair of spaced-apart flanges extending from the rib adherent surface and positioned to project from the rib adherent surface on opposing sides of a notch of a rib.

FUEL TANK ACCESS PANEL HEAT EXCHANGER

An access panel to be received in an access aperture in a lower skin of a wing on an aircraft incorporates a body surrounded by a sealing flange. The body is configured to be received in the access aperture and the sealing flange is configured to be received on a sealing land surrounding the access aperture. An integral heat exchanger extends from a top surface of the body into a fuel tank in the wing to conduct heat from the fuel to an external surface of the access panel.

Devices and methods to structurally close and seal openings in an aircraft wing fuel tank

Closure devices and methods are provided for closing a stringer penetration space defined between a stringer and a wing rib of an aircraft wing section. According to certain embodiments, the closure devices will integrally include a forward face plate positioned in covering relationship to at least a portion of the stringer penetration space, and a rearwardly projecting attachment arm rigidly adapted for rigid attachment to the stringer so as to positionally fix the forward face plate relative to the stringer penetration space.

Single piece vent dam

A dam for use with a duct having a longitudinal axis. The dam employs a single piece insert having a first lateral flange and a second lateral flange configured to engage opposing interior lateral surfaces of the duct. The insert engages the duct in sealing contact in a seated position. The first and second lateral flanges are offset longitudinally along the longitudinal axis and joined with a curved wall having a curvature shaped to be received, with the insert oriented at an insert angle about a normal axis perpendicular to the longitudinal axis, in an aperture in the duct.

Noise attenuating device to reduce noise generated by an opening in a skin of an aircraft

A noise attenuating device for reducing acoustic resonance in a cavity of an aircraft with an opening in a skin of the aircraft defining a first surface area and an opening peripheral edge includes a connection mechanism for securing the noise attenuating device in proximity to the opening in the skin of the aircraft and an exterior surface. The exterior surface defines a second surface area that is less than the first surface area of the opening and a device peripheral edge, which has a first section having an edge profile complimentary to at least a portion of the opening peripheral edge and a second section having an indented edge profile in relation to the first section such that when the noise attenuating device is secured within the opening, at least one gap is formed between the device peripheral edge and the opening peripheral edge.

Part edge seal arrangement and joining method

A seal arrangement is provided for sealing an exposed edge of a composite laminate part having a fay surface configured to be joined to a structure. The seal arrangement includes a precured edge seal covering the exposed edge and a cover covering the edge seal. A seal bead located within a recess in the fay surface of the part forms a seal between the part and the structure.
