Submarine

Abstract

An essentially cylindrical, elongate pressure hull includes at least one pressure antechamber arranged essentially transversely to a longitudinal axis of the pressure hull. The pressure antechamber includes an access opening to the pressure hull which is closable in a pressure-tight manner and an access opening to the outside which is closable in a pressure-tight manner.

What is claimed is:  
     
         1 . A submarine with a substantially cylindrical, elongate pressure hull which comprises at least one pressure antechamber arranged essentially transversely to a longitudinal axis of the pressure hull, wherein the pressure antechamber comprises an access opening to the pressure hull which is closable in a pressure-tight manner, and an access opening to an outside of the pressure hull which is closable in a pressure-tight manner.  
     
     
         2 . A submarine according to  claim 1 , wherein: the pressure antechamber at least partly passes through the pressure hull.  
     
     
         3 . A submarine according to  claim 1 , wherein: the pressure antechamber is arranged next to the pressure hull in the region of the tower and connects to the pressure hull substantially tangentially.  
     
     
         4 . A submarine according to  claim 1 , wherein: the pressure antechamber is arranged within a section of the pressure hull at which the tower is also arranged.  
     
     
         5 . A submarine according to  claim 1 , wherein: the pressure antechamber has an elongate shape and the access opening to the outside is formed by an end lid.  
     
     
         6 . A submarine according to  claim 1 , wherein: the pressure antechamber has an oval or double-ring-shaped cross section.  
     
     
         7 . A submarine according to  claim 1 , wherein: the pressure antechamber has an essentially rectangular cross section.  
     
     
         8 . A submarine according to  claim 1 , wherein: the access opening of the pressure antechamber is closable to the outside by way of a section which is part of the pressure hull casing.  
     
     
         9 . A submarine according to  claim 1 , wherein: the pressure antechamber has an elongate shape and the access opening to the pressure hull lies in a longitudinal wall.  
     
     
         10 . A submarine according to  claim 1 , wherein: the pressure antechamber is designed as a decompression chamber.  
     
     
         11 . A submarine according to  claim 1 , wherein: the pressure antechamber is designed for accommodating an underwater craft.  
     
     
         12 . A submarine according to  claim 4 , wherein: the pressure antechamber has an elongate shape and the access opening to the outside is formed by an end lid; 
 the access opening of the pressure antechamber is closable to the outside by way of a section which is part of the pressure hull casing;    the pressure antechamber has an elongate shape and the access opening to the pressure hull lies in a longitudinal wall;    the pressure antechamber is designed as a decompression chamber;    the pressure antechamber is designed for accommodating an underwater craft.    
     
     
         13 . A submarine according to  claim 12 , wherein: the pressure antechamber at least partly passes through the pressure hull; 
 the pressure antechamber has an oval or double-ring-shaped cross section.    
     
     
         14 . A submarine according to  claim 12 , wherein: the pressure antechamber at least partly passes through the pressure hull; 
 the pressure antechamber has an essentially rectangular cross section.    
     
     
         15 . A submarine according to  claim 12 , wherein: the pressure antechamber is arranged next to the pressure hull in the region of the tower and connects to the pressure hull substantially tangentially; 
 the pressure antechamber has an oval or double-ring-shaped cross section.    
     
     
         16 . A submarine according to  claim 12 , wherein: the pressure antechamber is arranged next to the pressure hull in the region of the tower and connects to the pressure hull substantially tangentially; 
 the pressure antechamber has an essentially rectangular cross section.    
     
     
         17 . A method for retrofitting a pressure antechamber in a submarine, the method comprising the steps of: dividing the submarine transversely to a longitudinal axis of the submarine; a submarine section containing the pressure antechamber is integrated in-between the divided submarine.  
     
     
         18 . A method according to  claim 17  wherein: the submarine is transversely divided in a region of a tower and the integrated submarine section also comprises a tower section.
