Window element for a double-shell skin field of an aircraft fuselage cell
A window element for a double-shell skin field of an aircraft fuselage cell includes a window frame having a window module disposed in the frame, wherein the frame is disposed in an opening of the double-shell skin field, and wherein the frame is connected to the double-shell skin field by a surrounding embrasure profile positioned against a core structure of the skin field at least in some regions, wherein the core structure includes an inner and an outer covering layer.
1. A window element for a double-shell skin field of an aircraft fuselage cell, the double-shell skin field including a core structure disposed between an inner covering layer and an outer covering layer and having an opening, the window element comprising:
a window frame disposed within the opening of the double-shell skin field; having
a window module disposed in the window frame; and, wherein the frame is disposed in an opening of the double-shell skin field, and wherein the frame is connected to the double-shell skin field by a surrounding
an embrasure profile surrounding the window frame, the embrasure profile connecting the window frame to the double-shell skin field and being positioned against a the core structure of the skin field at least in some regions, wherein the core structure includes an inner and an outer covering layer,
wherein the embrasure profile includes a C-shaped cross-sectional geometry with an inner and an outer arm running parallel to one another, and wherein the inner and the outer arms are connect connected by a profile web,
wherein the frame has an inner and an outer flange connected to one another by a flange web,
wherein the outer flange includes a recess, and
wherein the outer covering layer is positioned against the outer flange at least regions.
2. The window element as recited in claim 1 , further comprising an outer covering layer opening and an inner covering layer opening, wherein the outer covering layer opening is of smaller extent than the inner covering layer opening, and wherein an opening of the core structure is of larger extent than the inner covering layer opening.
3. The window element as recited in claim 1 , wherein the outer arm is longer than the inner arm.
4. The window element as recited in claim 1 , wherein the inner flange is disposed on the inner covering layer.
5. The window element as recited in claim 1 , wherein the outer covering layer is connected to the outer arm and to the outer flange.
6. The window element as recited in claim 5 , wherein the outer covering layer is at least one of riveted, bolted and attached with adhesive to the inner covering layer and to the outer flange.
7. The window element as recited in claim 1 , wherein the inner arm is connected to the inner covering layer and to the inner flange.
8. The window element as recited in claim 7 , wherein the inner arm is at least one of riveted, bolted and attached with adhesive to the inner covering layer and to the inner flange.
9. The window element as recited in claim 1 , wherein the profile web is connected to the core structure at least in some regions.
10. The window element as recited in claim 9 , wherein the profile web is attached to the core structure with adhesive.
11. The window element as recited in claim 1 , wherein an intermediate space is disposed between the flange web and the profile web.
12. The window element as recited in claim 1 , wherein the inner covering layer and the outer covering layer contain a first material and the core structure contains a second material that is different from the first material.
13. The window element as recited in claim 1 , wherein the embrasure profile is disposed between the inner covering layer and the outer covering layer.
14. The window element as recited in claim 1 , wherein the profile web abuts the core structure.
