Fuselage structure and method for the production of a fuselage structure

1. A fuselage structure of an aircraft or spacecraft comprising:

an inner shell arrangement which has an upper inner shell and a lower inner shell, the upper inner shell being spaced apart at least in some sections from the lower inner shell by a first gap in order to form a window region;

a window band which is arranged at least in the window region and has a pane device which comprises a grid structure which absorbs fuselage forces;

wherein the fuselage structure comprises an outer shell arrangement which has an upper outer shell associated with the upper inner shell and a lower outer shell associated with the lower inner shell, the upper outer shell being spaced apart at least in some sections in the window region from the lower outer shell by a second gap;

wherein the outer shells are spaced from the inner shells for accommodating a core material between the inner and outer shell arrangements; and

wherein the grid structure extends beyond the window region, which is formed by the first and second gaps, into the shell arrangements and is fastened to the individual shells of the inner and outer shell arrangements in order to form a fuselage structure which connects the individual shells to one another and is optimized in terms of force flux.

2. The fuselage structure according to claim 1 , wherein the grid structure has individual grid ribs for forming grid meshes, the grid structure being designed to absorb the forces occurring in the fuselage.

3. The fuselage structure according to claim 1 , wherein the grid structure is designed as a lattice grid structure and, in terms of shape configuration, is matched to the shape of the shell arrangements.

4. The fuselage structure according to claim 1 , wherein the first gap and the second gap are formed at the same height and, at least in some sections, such that they run in the longitudinal direction of the fuselage structure, in order to form an optimized window region.

5. The fuselage structure according to claim 1 , wherein the first gap and the second gap have the same gap widths and/or gap lengths.

6. The fuselage structure according to claim 1 , wherein the pane device has at least two individual panes which each end flush with the associated inner and/or outer shells, can be fastened to the inner and/or outer shells and enclose the grid structure between them.

7. The fuselage structure according to claim 1 , wherein a suitable core material is provided between the inner shells and the outer shells, at least with the exception of at least the window region.

8. An aircraft or spacecraft with a fuselage structure which is designed according to claim 1 .
