Embodiment Construction

[0018] The present disclosure describes various methods and systems for efficiently attaching an aircraft wing to an aircraft body. As will be described in more detail below, in one embodiment, the aircraft wing can be attached to the aircraft body by fasteners without the use of any fastening means through the wing assembly, so that the aircraft body and Wing assembly attached. The following description and attached figure 1 to attach Figure 8 These are described in detail so that various embodiments of the present invention can be fully understood. However, for the sake of brevity and clarity, well-known structures and systems generally associated with aircraft wings, fuselages, and aircraft structures will not be described in this disclosure.

[0019] Details, dimensions, angles, and other features shown in the drawings are merely illustrative of certain embodiments of the present disclosure. Accordingly, other embodiments having other details, dimensions, angles, and ...

Abstract

The present disclosure generally relates to an aircraft body (3) comprising a fuselage skin on an outer member of the aircraft body (3) and a wing box (10) extending through the member of the aircraft body (3) ). The wing box (10) is closed and capable of being pressurized, the wing box is fixedly attached at the outer surface to at least one pair of attachment members (20) fixedly attached to the aircraft body (3) and the attachment Connect components.

Description

technical field [0001] The present invention relates generally to aircraft structures and, more particularly, to aircraft wing-to-fuselage attachment structures. Background technique [0002] A significant portion of the time spent in aircraft final assembly is devoted to attaching wing assemblies to the aircraft body. Traditional wing-to-fuselage mounting attaches frame stubs used to splice the outer wing boxes to the center wing box and vertical flanges that connect the aircraft body skin to the wing boxes. The interface with the wing box includes short beams of the body frame, wing box truss struts and fasteners. The aircraft fuselage side panel frame is split in two so that the lower frame portion can be deflected relative to the wing to fuselage joint. In this configuration, additional frame weight is added due to splicing of the aircraft fuselage frames. Also, the additional fuel barrier application process produces noxious fumes and cannot be fully completed until ...
