Abstract
A blade assembly () for a turbine () including a vibration damper () having a mounting base () sealingly disposed at an inlet end () of a cooling fluid passageway () within the root section () of the blade assembly and including an opening () in the mounting base for passing cooling fluid into the cooling passageway. The opening is sized to function effectively as an orifice for limiting a maximum flow rate of cooling fluid in the event of a breach of the cooling fluid passageway downstream of the inlet end. A wear feature () is formed on the distal end of the vibration damper opposed the mounting base for rubbing interface with a complementary wear feature attached to a wall () of the cooling fluid passageway. The wear feature may include a non-planar wear surface such as angularly disposed wear surfaces () effective to resist vibrational movement in two directions.
