Lining for an aircraft
View Patent ↗A lining for an aircraft. The lining separates an intermediate space from an interior space of the aircraft in a pressuretight manner. The lining panels extend either substantially horizontally or are fastened approximately vertically on a lining framework formed by profiles for connection to the fuselage cell. At least one of the lining panels allows automatic pressure equalization between the interior space and the intermediate space in the event that the pressure in the interior space drops to something in the order of 0 hPa. This pressure corresponds to the air pressure prevailing at an altitude above 10,000 m. Mounts of the lining panels are provided with predetermined breaking points. The predetermined breaking points are formed in particular by plastic nuts, the thread of which tears away when a critical load-bearing capacity is exceeded.
1. A lining for a fuselage cell of an aircraft, comprising:
at least one lining panel; and
an intermediate space existing between the fuselage cell and the lining, wherein the at least one lining panel has such a connection to the fuselage cell passing through the intermediate space that, when there is a rapid drop in pressure between an interior space of the fuselage cell and the intermediate space, the at least one lining panel exposes at least one gap to allow pressure equalization, wherein the at least one lining panel extends substantially horizontally and the connection of the at least one lining panel to the fuselage cell takes place by at least one tensioned cable, the at least one lining panel being supported against at least two supports which can be adjusted in length and are fastened to the fuselage cell.
2. The lining according to claim 1 , wherein, starting from a first articulation point in a region of a first edge of the at least one lining panel, the cable is led over a first cable guide, arranged on one support of the at least two supports, over at least one holding point, fastened in the central region of the lining panel, and, from the holding point, the cable is led further over a second cable guide, arranged on the support, to a second articulation point in the region of a second edge, lying opposite the first edge.
3. The lining according to claim 2 , wherein the at least one holding point has a predetermined breaking point in such a way that the holding point gives way above a critical load-bearing capacity of the at least one lining panel.
4. The lining according to claim 2 , wherein the at least one holding point is formed by a threaded bolt which has a third cable guide.
5. The lining according to claim 4 , wherein the at least one holding point formed by a threaded bolt which has a third cable guide is fastened by means of a plastic nut as a predetermined breaking point in the at least one lining panel.
6. The lining according to claim 1 , wherein a length of the at least one cable is dimensioned in such a way that uncontrolled lowering of the at least one lining panel is prevented.
7. The lining according to claim 1 , wherein the at least one lining panel adjoins another lining panel, wherein the lining panels have seals in each case along the edges of the lining panels and adjoin one another in a pressuretight manner.
