Problems solved by technology
[0004] In particular, the connection of the main wing requires high assembly outlay, which leads to high cost
The disadvantage here is that in the case of the connection between the wing and the wing box, loads are introduced around the corners, which reduces the stability of the connection and constitutes a disadvantageous load transfer from the wing into the fuselage

Embodiment Construction
[0031] In the ensuing description and figures, in order to avoid repetitions, identical components and components are at least partially also marked with the same reference numerals, as long as no further distinction is required for the description.
[0032] According to the invention, the wing-fuselage-structure B is used to connect two wing shells-upper parts 11, 12, respectively associated with one of the two main wings F1, F2, with the fuselage section of the aircraft. Body-shell part 30 or fuselage-upper shell part 50 or fuselage-lower shell part connection. figure 1 An embodiment of a wing shell-upper part 11 according to the invention with a longitudinal direction L1 is shown. The wing shell upper part 11 is integrated into the wing F1 in such a way that the longitudinal direction L1 extends in the spanwise direction S1 of the wing F1 . The wing shell upper part 11 has two sections, a wing-side shell part 11 a and a fuselage-side shell part 11 b , which are arranged co...

The invention relates to a wing-fuselage structural component (B) for the connection of two airfoils (F1, F2) and a fuselage section (3) of an air aircraft, having: a first wing shell part (11) for the first wing (F1) and a second wing shell part (12) for the second wing, each of which is produced in one part and formed from a shell part (11 a, 12a) on the wing side and a shell part (11 b, 12b) on the fuselage side, wherein each shell part (11 b, 12b) on the fuselage side has connecting parts (31, 32, 33; 41, 42) and recesses (34, 35; 43, 44, 45) in each case between the connecting parts, wherein the connecting parts and the recesses of the shell part (11 b, 12b) on the fuselage side for the first wing (F1) and of the shell part (11 b, 12b) on the fuselage side for the second wing (F2) interlock in the assembled state and wherein at least two connecting parts (31, 32, 33; 41, 42), on their shell part (11a, 12a) on the wing side, have an elongation part (31 a, 32a, 33a; 41a, 42a), a partially cylindrical fuselage shell part (30), the supporting edges (51, 52) of which have recesses (51 a, 51 b), with which the elongation paths of the wing shell parts (12) interlock.
Description
technical field [0001] The invention relates to a wing-fuselage structure for connecting two main wings and fuselage sections on an aircraft. [0002] The invention relates to a wing-fuselage structure for connecting two main wings and fuselage sections on an aircraft. In this case, each of the two main wings has a shell part which is integrated or to be integrated in the wing upper shell, wherein the two shell parts together form a wing-fuselage structure. Background technique [0003] In the prior art, the wing-fuselage connection is currently formed by means of wing boxes. A wing box is a separate component from the main wing, which is usually formed from a number of different parts, wherein the parts used to form the wing box are welded to each other and / or connected by connecting elements. Typically, wing boxes are made of metal, which can develop corrosion over time. The wing box has connection elements for the wing connection or the fuselage connection, which likew...
