Wire seal

Abstract

The disclosure concerns a wire seal for sealing a gap between two components of a gas turbine, the wire seal including a first core and a second core spaced apart from one another, a wire pack extending around the first core and the second core, and a fastener for securing the wire pack to the first core and the second core, wherein the wire seal is curved. Various embodiments are disclosed, including various types of fastener. A method of manufacturing a wire seal is also disclosed.

1 . A wire seal for sealing a gap between two components of a gas turbine, the wire seal comprising:
 a first core and a second core spaced apart from one another,   a wire pack extending around the first core and the second core, and   a fastener for securing the wire pack to the first core and the second core, wherein the wire seal is curved.   
     
     
         2 . The wire seal of  claim 1 , comprising:
 a plate with a first face, a second face, a first edge including the first core, a second edge including the second core and two end edges, wherein the first edge is opposite the second edge,   wherein the wire pack extends around the first face, the first edge, the second face and the second edge of the plate, and   wherein the fastener secures the wire pack around the plate.   
     
     
         3 . The wire seal of  claim 1 , wherein the fastener comprises:
 a first clamp for securing the wire pack to the first core and a second clamp for securing the wire pack to the second core.   
     
     
         4 . The wire seal of  claim 1 , wherein the fastener comprises:
 at least one end piece attached at each end of the first core and the second core, to hold the wire pack in place adjacent to the first core and the second core.   
     
     
         5 . The wire seal of  claim 1 , wherein the fastener extends around the wire pack from the first core to the second core, to hold the wire pack in place adjacent to the plate. 
     
     
         6 . The wire seal of  claim 2 , comprising:
 a first core wire attached to the first edge and a second core wire attached to the second edge.   
     
     
         7 . The wire seal of  claim 1 , wherein the wire seal is a conical wire seal. 
     
     
         8 . The wire seal of  claim 1 , wherein the first core is a first core wire and the second core is a second core wire. 
     
     
         9 . A gas turbine comprising the wire seal of  claim 1 . 
     
     
         10 . The gas turbine of  claim 9 , comprising:
 a combustor and a first vane separated by a gap, and wherein the wire seal is arranged to seal the gap.   
     
     
         11 . The gas turbine of  claim 10 , wherein the combustor comprises:
 a picture frame and wherein the gap is between the first vane and the picture frame.   
     
     
         12 . The gas turbine of  claim 11 , comprising:
 a socket in the picture frame, and wherein the wire seal is seated in the socket.   
     
     
         13 . A method of manufacturing a wire seal for sealing a gap between two components of a gas turbine, the wire seal having a first core and a second core spaced apart from one another, a wire pack extending around the first core and the second core, and a fastener for securing the wire pack to the first core and the second core, wherein the wire seal is curved, the method comprising:
 placing the wire pack around the plate; and   fastening the wire pack to the plate with the fastener.   
     
     
         14 . The method of  claim 13 , in which the wire pack is made of wire and is placed around the first core and the second core by winding the wire repeatedly around the first core and the second core.
