SYSTEM FOR DAMPING VIBRATIONS IN TURBINE

摘要

PROBLEM TO BE SOLVED: To provide an improved system for damping vibrations in a turbine.SOLUTION: A system for damping vibrations in a turbine includes a first rotating blade having: a first ceramic airfoil; a first ceramic platform connected to the first ceramic airfoil; and a first root connected to the first ceramic platform. A second rotating blade adjacent to the first rotating blade includes a second ceramic airfoil, a second ceramic platform connected to the second ceramic airfoil, and a second root connected to the second ceramic platform. A non-metallic platform damper has a first position in simultaneous contact with the first and second ceramic platforms.
