Abstract

A passenger aircraft with a passenger cabin is described, wherein the passenger aircraft comprises a fully functional door, which is openable and closable and which is adapted for an entrance and an exit of passengers, and en emergency exit door, which is exclusively adapted for an emergency exit of passengers from the passenger cabin. Therein, the emergency exit door is arranged in an area of a fuselage of the passenger aircraft, which is arranged ahead of and/or behind of wings of the passenger aircraft.

First claim

What is claimed is:

1. A passenger aircraft with a passenger cabin, comprising:
a fully functional door that is openable and closable and that is designed for the entry and exit of passengers; and
an emergency exit door that is designed exclusively for the emergency exit of passengers from the passenger cabin;
wherein the emergency exit door is arranged in a region of an external skin of the passenger aircraft, which region is arranged forward or aft of wings of the passenger aircraft,
wherein the emergency exit door is locked by press fit bolts, each comprising a conic part that fits into a respective conical hole extending through the emergency exit door and the external skin,
wherein the bolts are insertable into and removable from their respective conical holes through a lever arrangement in the emergency exit door, and
wherein the bolts frame a door cutout of the emergency exit door.

2. The passenger aircraft of claim 1 ,
wherein the emergency exit door is designed to be load bearing.

3. The passenger aircraft of claim 1 ,
wherein the emergency exit door is reversibly openable.

4. The passenger aircraft of claim 1 ,
wherein the press fit bolts are designed to detachably affix the emergency exit door to the external skin of the passenger aircraft.

5. The passenger aircraft of claim 1 ,
wherein the emergency exit door is detachably affixed with positive-locking fit in the external skin of the passenger aircraft.

6. The passenger aircraft of claim 1 ,
wherein the bolts are screwed into nuts.

7. The passenger aircraft of claim 6 ,
wherein the emergency exit door comprises at least one explosive charge which is adapted for destroying the bolts or the nuts each at a predetermined breaking point.

8. The passenger aircraft of claim 1 ,
wherein the bolts comprise a non-conic form-fit part.

9. The passenger aircraft of claim 7 ,
wherein the emergency exit door comprises a barometric control which is adapted for securing the ignition of the at least one explosive charge.

10. The passenger aircraft of claim 1 ,
wherein an amplified device is adapted for supporting an opening of the emergency exit door.
