Turbine blade or vane

Abstract

A turbine blade or vane includes passages in the interior. Further, in the region of a radial end of a partition which delimits a passage, a shoulder is provided. On the shoulder there rests an insert which closes off the at least one passage. As such, the end of a partition is produced in such a manner that it is optimized in terms of flow retained.

What is claimed is:  
     
         1 . A turbine blade, comprising: 
 a pedestal, adapted to secure the turbine blade, and including at least one outer pedestal wall,    a plurality of inner passages, the passages at least being formed by at least one inner partition, wherein at least one passage is closed off in the region of the pedestal, wherein at least one partition and a pedestal wall include a shoulder, and wherein an insert rests at least partially on the shoulder and is adapted to close off the passage with respect to the outside in the pedestal region.    
     
     
         2 . The turbine blade as claimed in  claim 1 , wherein the shoulder is formed on an inner surface of the passage and creates a relative widening of a cross section of an opening of the passage.  
     
     
         3 . The turbine blade as claimed in  claim 1 , wherein the insert and the partition are optimized in terms of flow.  
     
     
         4 . The turbine blade as claimed in  claim 1 , wherein the insert and the partition are rounded at a radial end.  
     
     
         5 . A turbine vane, comprising: 
 a pedestal, adapted to secure the turbine vane, and including at least one outer pedestal wall,    a plurality of inner passages,the passages at least being formed by at least one inner partition, wherein at least one passage is closed off in the region of the pedestal, wherein at least one partition and a pedestal wall include a shoulder, and wherein an insert rests at least partially on the shoulder and is adapted to close off the passage with respect to the outside in the pedestal region.    
     
     
         6 . The turbine vane as claimed in  claim 5 , wherein the shoulder is formed on an inner surface of the passage and creates a relative widening of a cross section of an opening of the passage.  
     
     
         7 . The turbine vane as claimed in  claim 5 , wherein the insert and the partition are optimized in terms of flow.  
     
     
         8 . The turbine vane as claimed in  claim 5 , wherein the insert and the partition are rounded at a radial end.  
     
     
         9 . A turbine blade, comprising: 
 a pedestal, adapted to secure the turbine blade; and    a plurality of inner passages, the passages being formed in the interior of the pedestal, wherein a shoulder is provided in a region of a radial end of a partition which delimits a passage, and wherein an insert, adapted to close off at least one passage, rests on the shoulder.    
     
     
         10 . The turbine blade of  claim 9 , wherein the end of the partition is produced in such a manner that it is optimized in terms of flow retained.  
     
     
         11 . The turbine blade of  claim 9 , wherein the shoulder is formed on an inner surface of the passage and creates a relative widening of a cross section of an opening of the passage.  
     
     
         12 . The turbine blade of  claim 9 , wherein the insert and the partition are optimized in terms of flow.  
     
     
         13 . The turbine blade of  claim 9 , wherein the insert and the partition are rounded at a radial end.  
     
     
         14 . A turbine vane, comprising: 
 a pedestal, adapted to secure the turbine vane; and    a plurality of inner passages, the passages being formed in the interior of the pedestal, wherein a shoulder is provided in a region of a radial end of a partition which delimits a passage, and wherein an insert, adapted to close off at least one passage, rests on the shoulder.    
     
     
         15 . The turbine vane of  claim 14 , wherein the end of the partition is produced in such a manner that it is optimized in terms of flow retained.  
     
     
         16 . The turbine vane of  claim 14 , wherein the shoulder is formed on an inner surface of the passage and creates a relative widening of a cross section of an opening of the passage.  
     
     
         17 . The turbine vane of  claim 14 , wherein the insert and the partition are optimized in terms of flow.  
     
     
         18 . The turbine blade of  claim 14 , wherein the insert and the partition are rounded at a radial end.
