Abstract
Official abstract text for this publication.
A stationary guide vane includes a top platform, a bottom platform, and a vane body located between the top platform and the bottom platform. The vane body includes one or more cavities formed on a side wall of the vane body. One or more of the cavities are filled with vibration damping material and a vane cover is bonded to the vane body over the one or more containers.
First claim
Opening claim text (preview).
The invention claimed is: 1. A stationary guide vane comprising: a top platform; a bottom platform; a vane body located between the top platform and the bottom platform, wherein the vane body includes one or more cavities formed on a side wall of the vane body; one or more containers filled with a vibration damping material and bonded within the one or more cavities formed in the vane body; and a vane cover bonded to the vane body over the one or more containers; wherein the vibration damping material is steel shot. 2. The stationary guide vane of claim 1 , wherein the one or more containers are filled with the vibration damping material to a level less than 100% filled. 3. The stationary guide vane of claim 2 , wherein the one or more containers are filled with the vibration damping material to a level of approximately 90%. 4. The stationary guide vane of claim 1 , wherein the one or more containers are located in the vane body at a point of maximum inflection of the stationary guide vane. 5. The stationary guide vane of claim 1 , wherein the vane body is aluminum. 6. A stationary guide vane comprising: a top platform; a bottom platform; a vane body located between the top platform and the bottom platform, wherein the vane body includes one or more cavities formed on a side wall of the vane body; one or more containers filled with a vibration damping material to a level equal to or less than 90%, and bonded within the one or more cavities formed in the vane body; and a vane cover bonded to the vane body over the one or more containers; wherein the vibration damping material is steel shot. 7. The stationary guide vane of claim 6 , wherein the one or more containers are located in the vane body at a point of maximum inflection. 8. The stationary guide vane of claim 6 , wherein the vane body is aluminum. 9. A stationary guide vane comprising: a top platform; a bottom platform; a vane body located between the top platform and the bottom platform, wherein the vane body includes one or more cavities formed on a side wall of the vane body, wherein vibration damping material is located in one or more of the cavities; and a vane cover bonded to the vane body over the one or more cavities; wherein the vibration damping material is steel shot. 10. The stationary guide vane of claim 9 , wherein the cavities are filled with the vibration damping material to a level less than 100% filled. 11. The stationary guide vane of claim 10 , wherein the cavities are filled with the vibration damping material to a level of approximately 90%. 12. The stationary guide vane of claim 9 , wherein one or more of the cavities remains unfilled with vibration damping material. 13. The stationary guide vane of claim 9 , wherein the vane cover includes one or more holes for supplying the vibration damping material to the one or more cavities after bonding of the vane cover to the vane body. 14. The stationary guide vane of claim 13 , further including a second vane cover that is bonded to the vane cover after the vibration damping material has been supplied to the one or more cavities.
