A damper that provides damping for turbine engines to reduce vibrations in the blades, vanes, shrouds, ducting, liner walls and/or other components of the turbine engine. The damper includes an air cavity in a blade, vane, shroud or other engine component and a material covering at least a portion of the air cavity. Vibrations in the turbine engine and its components produce movement of the air inside the air cavity resulting in a corresponding viscous force that dampens the vibrations.
1. Dampers for damping vibrations of a turbine engine, each of said dampers being disposed in a component of said turbine engine and said damper comprising a cavity wherein said cavity is disposed within said component and has one or two exterior sides with a material covering at least a portion of said exterior sides of said cavity, wherein said material coverings permit no net flow of exterior gases into said cavity, and wherein said gases in said cavity are the sole damping agent disposed within said walls of said cavity. 2. The damper according to cl...
