Embodiment Construction

[0018] refer to figure 1 and figure 2 , discloses a fluid-tight mechanical fastening system, generally indicated at 100, and a structural assembly, generally indicated at 10, comprising a connection to a second member using the disclosed fluid-tight mechanical fastening system 100 14 of the first member 12 . As described in greater detail herein, the disclosed fluid-tight mechanical fastening system 100 can facilitate externally connecting the first member 12 to the second member 14 (from the outer side 13( figure 2 )), while maintaining the fluid impermeability of the first member 12.

[0019] In one particular application, the disclosed structural assembly 10 may be a wing of an aircraft, such as a passenger or commercial aircraft. Thus, first member 12 of structural assembly 10 may include an aircraft wing skin panel 16 and optionally a stringer 18 connected to skin panel 16 , while second member 14 of structural assembly 10 may include spar ribs 20 . However, those s...

Abstract

A structural assembly including a first member having an external side and an internal side, the first member defining a first member through-bore, a second member having an external side and an internal side, the second member defining a second member through-bore aligned with the first member through-bore, and a mechanical fastening system including a bushing at least partially received in the first member through-bore, the bushing defining a bushing through-bore and including a flange, wherein the flange is positioned in a gap between the internal side of the first member and the external side of the second member, a nut plate connected to the internal side of the second member, the nut plate defining a clearance bore aligned with the second member through-bore and the bushing through-bore, the nut plate including a nut, and a bolt extending through the bushing through-bore and into threaded engagement with the nut.

Description

technical field [0001] This application relates to mechanical fasteners, and more particularly, to structural assemblies assembled using mechanical fasteners, such as aircraft wings, and even more particularly, to fluid-tight fasteners for aircraft wing assemblies. , liquid-tight) mechanical fastening system. Background technique [0002] Airfoils for aircraft are typically constructed of ribs, spars, and skin panels (eg, upper and lower skin panels). Specifically, the ribs are spaced apart from each other along the length of the wing. The front end of the rib is connected to the front spar, and the rear end of the rib is connected to the rear spar. An upper skin panel is attached to the upper portion of each rib, and a lower skin panel is attached to the lower portion of each rib. Thus, the ribs, spars and skin panels define an enclosed wing box, which is commonly used as a fuel tank on passenger and commercial aircraft. [0003] When jet fuel is stored within wing boxe...
