Patent abstract
A stator assembly having an inner shroud and an outer shroud with a plurality of airfoils extending between the shrouds, and a vibration damping horn extending from one of the shrouds and aligned with the airfoil, the vibration damping horn having a higher stiffness than the airfoil, and where the vibration damping horn vibrates against a damping spring or within a viscous fluid to dampen the vibration of the stator assembly. The vibration damping horns are thicker than the airfoils to provide for the higher stiffness. The damping spring is enclosed between the shroud and seal to support the spring.
