Turbine blade rail damper

摘要

A device for damping of vibratory energy in the blades of rotor assemblies during operation where the blades (11a,11b) have a shroud (17a,17b) attached thereto with at least one sealing rail (19a,19b) extending radially outward from the shroud to an outer diameter surface. A damper element (21) is attached to the turbine blade sealing rail extending radially inward from the rail outer diameter surface along rail sides to maintain the damper element out of the flow of gas and positioned at a radial location on the blade for damping.
