A mechanical fastener system for EME protection, including at least one plated component, wherein the at least one plated component includes a base material, a bonding layer disposed over the base material, and a metal plating disposed over the bonding layer.

Mechanical fastener system for electromagnetic effect (EME) protection

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.

Part edge seal arrangement and joining method

Apparatuses and methods for aircraft wings, including fuel tank access panel assemblies, are disclosed. For example, an aircraft wing comprises a skin and a load bearing fuel tank access panel assembly fastened to the skin. The skin comprises a fuel tank access panel hole and a first fastener hole. The load bearing fuel tank access panel is configured to bear at least some of a wing bending load and comprises an access panel, a fastener, and a self-locking fastener mating assembly. The access panel comprises a body portion configured to be received in the fuel tank access panel hole, and a lip portion extending over an interior surface of the skin. The lip portion comprises a second fastener hole, and the fastener extends through the first fastener hole and the second fastener hole into the self-locking fastener mating assembly.

Aircraft fuel tank access panel assemblies

Systems and methods are provided for fabricating fasteners. One embodiment is an apparatus that includes a fastener. The fastener includes a head, a cylindrical shank that extends from the head and is dimensioned to engage in a fit with a corresponding hole, and a coating that is discontinuously speckled around a circumference of the shank and extends axially along the shank, leaving irregular portions of a surface of the shank exposed. The coating exhibits a higher lubricity than the surface, and the coating exhibits a higher dielectric withstand voltage than the surface.

Fasteners having enhanced electrical energy dispersion properties

A method and apparatus for forming a seal over a hole in a structure. The apparatus comprises a washer, a sleeve, and a fastener. The washer has a first channel. The sleeve has a second channel and an expandable section. The sleeve is positioned inside the first channel in the washer. The fastener has an elongate portion positioned inside the second channel of the sleeve to cause at least a portion of the expandable section of the sleeve to form a first interference fit with the washer.

Method for fuel tank spark containment

The disclosure generally relates to baffle fuel dams and tank boundary fuel dams having a single-piece or two-piece construction. In one example, a baffle fuel dam is a single piece having slotted holes sized and spaced to accommodate for tolerance variations during installation. The baffle fuel dams also include a base angle that allows installation at multiple locations. The disclosure also relates to tank boundary fuel dams that include a two-piece configuration which incorporates slotted holes to accommodate tolerance variations and that are sized/spaced for different installation locations. The tank boundary fuel dams may also include a base angle that allows installation at multiple locations.

Quick installation fuel dam

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.

Seal assembly for sealing relatively movable components

Apparatus for fuel tank spark containment

A method of installing a door in an access opening in a skin of an aircraft. A composite inner door panel is positioned against an inside face of the skin. A composite outer door panel is positioned against an outside face of the skin. A plurality of fasteners is installed through fastener openings in the composite outer door panel. The plurality of fasteners is tightened to form a chamfered interface between the skin and the composite outer door panel.

Composite access door

A door for an aircraft wing fuel tank access opening includes an outer impact resistant composite door panel, and an inner composite door panel. Double seals on the inner door panel prevent fuel leakage, and a chamfered outer edge on the outer door panel transfers a component of impact loads laterally into the wing skin to increase kinetic energy absorption.

Apparatus and methods described herein provide for a spillover tank to extend the fuel capacity of the main wing tank of an aircraft. The spillover tank is located in the wing of the aircraft adjacent to the main wing tank. At least one aperture exists through the shared barrier between the main wing tank and the spillover tank that allows fuel to flow passively between the tanks. A scavenge pump mechanism driven by motive flow from the main fuel pumps continuously pumps fuel from the spillover tank into the main wing tank.

Aircraft spillover fuel tank

Embodiments of the present disclosure provide an apparatus, method, and system for managing deflections comprising a fuel dam, a first portion of the fuel dam connected with a stringer, a second portion of the fuel dam connected with the first portion, and a third portion of the fuel dam. The second portion is more flexible than the first portion. The third portion is connected with the second portion, and connected with a rib. The second portion accommodates deflection between the stringer and the rib.

Fuel barrier

An aircraft joint comprises a wing structure and a wing tip. The wing structure has a first part of a clevis and lug fastening system located around an outer end of the wing structure. The wing tip has a second part of the clevis and lug fastening system located around an end of the wing tip. The wing tip is capable of being joined to the outer end of the wing structure. An upper aerodynamic surface and a lower aerodynamic surface are formed by joining the wing structure and the wing tip. The first part and the second part are located about a center between the upper aerodynamic surface and the lower aerodynamic surface. The first part and the second part engage each other such that a moment reaction occurs around the upper aerodynamic surface and the lower aerodynamic surface.
