Abstract
A rotor assembly (122) includes plural blades (124) and damping inserts (308). The blades include a carrier shroud (216) and a lid shroud (218) extending from an airfoil (200) of the respective blade in generally opposite directions. The carrier shrouds define pockets (302) at distal ends (224) thereof. The damping inserts are disposed in the pockets of the carrier shrouds of the blades and are free-floating within the pockets. The damping inserts are configured to dampen vibrations of the blades during rotation of the blades via engaging an interior surface (310) within the corresponding pocket of the carrier shroud and engaging a distal end (224) of the lid shroud of the neighboring blade. A contact force applied by each damping insert on the distal end of the lid shroud of the neighboring blade is based on a rotational speed of the blades.
