Damper system and a turbine

Abstract

A damper system and a turbine are provided. The damper system includes a plurality of CMC blades. Each CMC blade has a first member of a tip shroud, the first member opposite a second member of the tip shroud, a radial flange extending between the first member and the second member of the tip shroud, and at least one aperture in the radial flange for receiving a damping member, the dampening member joining and dampening adjacent CMC blades. The turbine includes a plurality of turbine blade tip shroud segments, each tip shroud segment having a first surface that cooperates with the first surface in an adjacent tip shroud segment to form a first opening, each tip shroud segment having a first receiving surface. The turbine includes a damper member that abuts the first receiving surface of each tip shroud segment.

What is claimed is: 
     
         1 . A damper system comprising:
 a plurality of CMC blades, each blade having
 a first member of a tip shroud, the first member opposite a second member of the tip shroud; 
 a radial flange extending between the first member and the second member of the tip shroud; and 
 at least one aperture in the radial flange for receiving a dampening member, the dampening member joining and dampening adjacent CMC blades. 
   
     
     
         2 . The damper system of  claim 1 , wherein dampening member circumferentially joins 360 degrees of CMC blades. 
     
     
         3 . The damper system of  claim 1 , wherein the dampening member is metal. 
     
     
         4 . The damper system of  claim 1 , wherein the dampening member is a metal wire. 
     
     
         5 . The damper system of  claim 1 , wherein the damper system further includes a metal collet adjacent the aperture. 
     
     
         6 . A turbine, comprising:
 a plurality of turbine blade tip shroud segments, each tip shroud segment having a first surface that cooperates with the first surface in an adjacent tip shroud segment to form a first opening, each tip shroud segment having a first receiving surface; and   a damper member that abuts the first receiving surface of each tip shroud segment.   
     
     
         7 . The turbine of  claim 6 , wherein the turbine blade tip shroud segments include a second surface that cooperates with the second surface in an adjacent tip shroud segment to form a second opening. 
     
     
         8 . The turbine of  claim 6 , wherein the turbine blade tip shroud segments include a second receiving surface that abuts the damper member. 
     
     
         9 . The turbine of  claim 6 , wherein the damper includes at least one holding member attached to at least one end of the damper member. 
     
     
         10 . The turbine of  claim 9 , wherein the holding member is integrally formed with the damper member. 
     
     
         11 . The turbine of  claim 9 , wherein the holding member circumferentially secures the damper member to the tip shroud segments. 
     
     
         12 . The turbine of  claim 6 , wherein the damper member is a metal. 
     
     
         13 . The turbine of  claim 6 , wherein the plurality of turbine blade tip shroud segments are ceramic matrix composites.
