A recently granted patent (Publication Number: US11891173B2) details an innovative aircraft structural assembly design. The assembly includes a fuselage portion with a passenger cabin and a wing unit attached to it. The wing unit features first and second wings with pressure fences attached to them, defining parts of the pressure vessel. These pressure fences, made of fence skins, are attached to the fuselage portion above the cabin floor, guiding fuselage frames for self-alignment in lateral directions. Stringers along the fuselage portion's longitudinal axis support the fence skins, creating a cradle for the fuselage portion.

Furthermore, the patent describes additional features such as fence frames supporting the fence skins, overlapping of the fence skins with fuselage frames, and upper wing skin portions contributing to the pressure vessel's structure. The design aims to enhance structural integrity and alignment within the aircraft assembly, showcasing a novel approach to fuselage and wing integration. This patent highlights advancements in aircraft engineering, focusing on optimizing pressure vessel construction and ensuring efficient assembly processes for improved performance and safety in aviation technology.
