Abstract
A rotor comprises a disk having a rim. The rim has an axial face facing one of a forward or rearward direction. The rim defines a circumferential groove. A damper engages with the rim at both the axial face and the circumferential groove. The disk includes a rotor hub having a hub inner surface facing a longitudinal axis about which the rotor hub rotates. The rim is spaced radially outwardly relative to the hub inner surface. The axial face extends radially inwardly from the rim to the hub inner surface. The circumferential groove is formed within the hub inner surface. The damper comprises a split ring damper with a first leg mounted within the circumferential groove and a second leg that extends from the first leg, surrounds a radial lip of the hub inner surface, and extends radially outwardly to contact the axial face. An integrally bladed rotor is also disclosed.
