ABSTRACT:
Damping of turbine or compressor vanes loosely supported in an outer shroud is accomplished by means of resilient metal damping pads which have slots to accommodate the outer ends of the vanes. The damping pads engage the opposite sides of the vanes and the slots are formed so as to provide gaps or relief areas between the pads and the side and end edges of the outer ends of the vanes.
