ABSTRACT:
A frictional damper is mechanically attached to a cast stator of the compressor section of a gas turbine engine so that a cantilevered end abuts one of the shrouds to prestress the individual ends of the vanes of the stator, which end is free to move by slotting that shroud between adjacent vanes.
