View Patent ↗A drainage device for letting out a fluid that is present between the exterior skin and the interior lining of an aircraft, wherein the drainage device comprises a collecting vessel and an outlet line. The collecting vessel is designed to collect the fluid that is present between the exterior skin and the interior lining and the outlet line is connected to the collecting vessel and is designed to let out the collected fluid.
1. A drainage device for letting out a fluid that is present between the exterior skin and the interior lining of an aircraft, wherein the drainage device comprises:
a collecting vessel;
an outlet line;
wherein the collecting vessel is configured to collect the fluid between the exterior skin and the interior lining;
wherein the outlet line is connected to the collecting vessel and is configured to let out the collected fluid; and
wherein the collecting vessel comprises a stringer.
2. The drainage device of claim 1 ,
wherein the collecting vessel is attachable between the exterior skin and the interior lining.
3. The drainage device of claim 2 ,
wherein the collecting vessel comprises a substantially S-shaped cross section.
4. The drainage device of claim 1 ,
wherein the collecting vessel is attachable to the exterior skin.
5. The drainage device of claim 1 ,
wherein the stringer is attached to the exterior skin at such orientation that said stringer forms a cavity with the exterior skin.
6. The drainage device of claim 1 ,
further comprising an attachment element, by which the stringer is attached to an insulating mat of the interior lining.
7. The drainage device of claim 1 ,
wherein the collecting vessel is formed by a stringer and at least one of the exterior skin and the interior lining.
8. The drainage device of claim 1 ,
wherein the outlet line comprises a hose.
9. The drainage device of claim 8 ,
wherein the hose comprises at least one branch line.
10. The drainage device of claim 1 ,
further comprising a drainage funnel that is arranged between the collecting vessel and the outlet line.
11. An aircraft comprising
an exterior skin;
an interior lining;
a drainage device for letting out a fluid that is present between the exterior skin and the interior lining, wherein the drainage device comprises:
a collecting vessel;
an outlet line;
wherein the collecting vessel is designed to collect the fluid between the exterior skin and the interior lining;
wherein the outlet line is connected to the collecting vessel and is designed to let out the collected fluid; and
wherein the collecting vessel comprises a stringer.
12. The aircraft of claim 11 ,
wherein the drainage device is arranged above an aircraft window.
13. The aircraft of claim 11 ,
wherein the drainage device is arranged above an aircraft door.
14. The aircraft of claim 11 ,
wherein the drainage device is configured to let out the collected fluid into a fuselage of the aircraft.
15. A method for letting out a fluid that is present between the exterior skin and the interior lining of an aircraft, comprising:
collecting the fluid by a collecting vessel between the exterior skin and the interior lining; and
letting out the collected fluid by an outlet line connected to the collecting vessel;
wherein the collecting vessel comprises a stringer.
