Abstract
An airfoil damping assembly includes an airfoil defining a hollow interior. Also included is an airfoil plurality of ribs disposed within the hollow interior. Further included is a plurality of cavities, each of the cavities defined by at least one of the plurality of ribs. Yet further included is a damping fluid disposed in one of the cavities to damp vibratory stresses of the airfoil during operation.
