Ceramic matrix composite component and a method of attaching a static seal to a ceramic matrix composite component

Abstract

A ceramic matrix composite (CMC) component and a method of attaching a static seal to a ceramic matrix composite component are provided. The CMC component includes a first end and a second end. A CMC metal interface member is attached to the second end. The CMC metal interface member is operable to join to a static seal in a gas turbine.

What is claimed is:  
     
         1 . A ceramic matrix composite component comprising:
 a first end;   a second end; and   a CMC metal interface member attached to the second end;   wherein the CMC metal interface member is operable to join to a static seal in a gas turbine.   
     
     
         2 . The ceramic matrix composite of  claim 1 , wherein the ceramic matrix composite component is a static component. 
     
     
         3 . The ceramic matrix composite of  claim 1 , wherein the ceramic matrix composite component is a vane or a nozzle. 
     
     
         4 . The ceramic matrix composite of  claim 1 , wherein the static seal is a honeycomb seal. 
     
     
         5 . The ceramic matrix composite of  claim 1 , wherein the static seal is attached to the CMC metal interface member by brazing or welding. 
     
     
         6 . The ceramic matrix composite of  claim 1 , wherein the CMC metal interface member is attached to the second end by a bolt. 
     
     
         7 . A method of attaching a metal seal to a ceramic matrix composite component comprising:
 providing a ceramic matrix composite component having a first end and a second end;   providing a CMC metal interface member;   attaching the CMC metal interface member to the second end of the ceramic matrix composite component;   providing a static seal; and   joining the static seal to the CMC metal interface member;   wherein the CMC metal interface member forms a plenum for purging rotor air.   
     
     
         8 . The method of  claim 7 , wherein the ceramic matrix composite component is a static component. 
     
     
         9 . The method of  claim 7 , wherein the ceramic matrix composite component is a vane or a nozzle. 
     
     
         10 . The method of  claim 7 , wherein the static seal is a honeycomb seal. 
     
     
         11 . The method of  claim 7 , wherein the static seal is joined to the CMC metal interface member by brazing or welding. 
     
     
         12 . The method of  claim 7 , wherein the CMC metal interface member is attached to the second end of the ceramic matrix component by a bolt.
