A method is provided for connecting two fuselage sections. A less complicated and time consuming method was found by using High-Speed-Drilling (HSD) for a group of final bore holes through the outer skin of at least one fuselage section and/or the coupling using one drilling template preferably without any pilot drilling.

In a method for manufacturing a shell, at least two shell sections are fabricated out of a composite fiber material, at least one compensation body of a plastically deformable material is secured to at least one limiting edge of at least one shell section, the shell sections are overlapped to form the shell, yielding flat seams between respectively adjacent shell sections. The at least one compensation body is arranged on at least one of the seams. In order to compensate for dimensional deviations in each overlap, the shape of the corresponding compensation bodies is changed, and the shells sections are joined together at the seams.

The present invention provides an interconnection, in particular in the field of aerospace. The interconnection has a T-stringer, an Ω-stringer and a connecting arrangement. The connecting arrangement connects base sections of the T-stringer and of the Ω-stringer to one another. This provides a coupling of an Ω-stringer to a T-stringer which is comparatively insensitive with respect to tolerances relating to the orientation of the Ω-stringer in relation to the T-stringer.

An aircraft fuselage including at least two sections kept assembled at a circumferential join, each section having at least one panel. The circumferential join includes at least one inner ring, situated on one face, called the inner face, of the fuselage. The inner ring has a width li, partially overlaps each of the two panels and is fixed to the two panels by fasteners. The fuselage also includes an outer ring, situated on one face, called the outer face, of the fuselage, opposite to the inner face. The outer ring has a width le, partially overlaps the two panels, and is fixed to the two panels and to the inner ring by some or all of the fasteners fixing the inner ring to the two panels.

The invention relates to a transverse butt connection (1, 24) between two fuselage sections (2, 3, 25, 26), more particularly for creating a fuselage cell for an aircraft, with a number of stringers (41, 42) arranged spaced out uniformly parallel to one another inside on an outer skin (4, 5, 27, 28).In order to enable a universal tolerance compensation with standardised compensating means within a predetermined tolerance band between two fuselage sections which are to be joined together, it is proposed according to the invention that both end areas (6, 7, 29, 30) of the fuselage sections (2, 3, 25, 26) have on the inside oppositely inclined skin wedge faces (8, 9) and the connection of the two end areas (6, 7, 29, 30) is carried out by a circumferential transverse butt strap (10, 31) which is provided with two oppositely inclined transverse butt strap wedge faces (12, 13) in the underneath area (11) wherein a wedge (14, 15, 33, 34) can be pushed in between each one transverse butt strap wedge face (12, 130) and a skin wedge face (8, 9) for tolerance compensation between the fuselage sections (2, 3, 25, 26).

An aircraft structure including stiffened panels assembled at the junction, without continuity of the stiffeners. Multiple panels are used to form the fuselage, tail units and wings of an aircraft. These panels include stiffeners which are interrupted at each panel junction. However, the stresses experienced by the stiffeners must be transmitted despite these interruptions. Known solutions require the use of at least one additional part per stiffener and per interruption. In order to solve this problem, the disclosed embodiments include a doubler necessitating at most one additional part per panel junction area for all of the interrupted stiffeners in this area.

Structures and methods for joining composite fuselage sections and other panel assemblies together are disclosed herein. In one embodiment, a shell structure configured in accordance with the present invention includes a first panel portion positioned adjacent to a second panel portion. The first panel portion can include a first stiffener attached to a first composite skin, and the second panel portion can include a second stiffener attached to a second composite skin. The shell structure can further include a fitting extending across a first edge region of the first panel portion and a second edge region of the second panel portion. A first end portion of the fitting can be attached to the first stiffener and the first composite skin, and a second end portion of the fitting can be attached to a second stiffener and a second composite skin, to join the first panel portion to the second panel portion.
