Arrangement for passing a line in a load-free manner through a pressure frame of a fuselage of an aircraft or spacecraft

Abstract

The present invention provides an arrangement for passing a line in a load-free manner through a pressure frame of a fuselage of an aircraft or spacecraft, including an opening penetrating the pressure frame, through which opening the line is passed, the line being mechanically decoupled from the pressure frame; and a flexible sealing device arranged outside the opening at least in portions, which sealing device is simultaneously operatively connected to the line and the pressure frame for the pressure-tight separation of a first side from a second side of the pressure frame. The present invention also provides a fuselage for an aircraft or spacecraft having an arrangement of this type and an aircraft or spacecraft having an arrangement of this type or having a fuselage of this type.

What is claimed is: 
     
         1 . An arrangement for passing a line in a load-free manner through a pressure frame of a fuselage of an aircraft or spacecraft, comprising:
 an opening penetrating the pressure frame, through which opening the line is passed, wherein the line is mechanically decoupled from the pressure frame;   and a flexible sealing device arranged outside the opening at least in portions, which sealing device is simultaneously operatively connected to the line and the pressure frame for the pressure-tight separation of a first side from a second side of the pressure frame.   
     
     
         2 . The arrangement according to  claim 1 , wherein the sealing device is formed in one piece. 
     
     
         3 . The arrangement according to  claim 1 , wherein a predetermined air gap is arranged between the line and an edge of the opening in order to achieve free movability of the line in the opening. 
     
     
         4 . The arrangement according to  claim 1 , wherein the sealing device is formed as a bellows. 
     
     
         5 . The arrangement according to  claim 1 , wherein the sealing device is arranged on the first side of the pressure frame. 
     
     
         6 . The arrangement according to  claim 1 , wherein the sealing device has approximately a truncated cone shape having a first end-face flange portion and a second end-face flange portion, the sealing device in particular tapering, starting from the second end-face flange portion, towards the first end-face flange portion. 
     
     
         7 . The arrangement according to  claim 1 , wherein the line comprises a first coupling device assigned to the first, in particular pressurised, side of the pressure frame, and a second coupling device assigned to the second, in particular unpressurised, side of the pressure frame. 
     
     
         8 . The arrangement according to  claim 7 , wherein the first coupling device is fixed to a first structural element of the fuselage, which structural element is assigned to the first side of the pressure frame, and the second coupling device is fixed to a second structural element assigned to the second side of the pressure frame. 
     
     
         9 . The arrangement according to  claim 7 , wherein the sealing device is fixed to the first coupling device of the line. 
     
     
         10 . The arrangement according to  claim 1 , wherein the arrangement comprises a flange which surrounds the opening, extends out from the pressure frame 
     
     
         11 . The arrangement according to  claim 10 , wherein the flange is tubular. 
     
     
         12 . The arrangement according to  claim 10 , wherein the flange extends out from the pressure frame on the first side thereof. 
     
     
         13 . The arrangement according to  claim 10 , wherein the sealing device is fixed to an end portion of the flange. 
     
     
         14 . The arrangement according to  claim 1 , wherein the line is formed as a fuel line. 
     
     
         15 . A fuselage for an aircraft or spacecraft having an arrangement according to  claim 1 . 
     
     
         16 . An aircraft or spacecraft having an arrangement according to  claim 1 .
