    Abstract: A blade is provided for a gas turbine engine. The blade includes an airfoil portion with at least one internal cavity and a damper located within the internal cavity. The damper includes a cantilever spring arm. A fan blade is provided for a gas turbine engine. The fan blade includes an airfoil portion with at least one internal cavity; and a damper located within the internal cavity. The damper includes a cantilever spring arm that terminates with a rub surface pad adjacent to a friction bridge between a concave pressure side and a convex suction side of the airfoil portion. A method is also provided for damping a blade of a gas turbine engine. The method includes deflecting a cantilever spring arm to contact a rub surface pad with a friction bridge between a concave pressure side and a convex suction side of an airfoil portion of the blade.

    Abstract: A damper includes a damper body that is configured to be attached to a workpiece during a machining process. A first side of the damper body is configured to abut a first side of the workpiece. The damper body includes a frame forming an outer periphery of the damper body, a plurality of damper nodes with a cavity in each damper node positioned in the frame, and a plurality of ribs extending between the frame and the damper nodes. A damping material is positioned in the cavity of each damper node.
