Abstract

A mid-turbine frame (64) of a gas turbine engine (24) includes a fairing (76) and a damping system (102). The fairing (76) includes an outer fairing wall (82), an inner fairing wall (84), and a plurality of struts (86). Each of the outer fairing wall (82) and the inner fairing wall (84) extends between and to an inner surface and an outer surface. The inner surface forms a core flow path (70) through the fairing (76). One of the outer fairing wall (82) or the inner fairing wall (84) forms a damping wall of the fairing (76). The damping system (102) includes at least one damping ring (106) and a plurality of clamp assemblies (104). The at least one damping ring (106) is disposed at the outer surface of the damping wall. The plurality of clamp assemblies (104) is circumferentially arrayed on the damping wall about the axis (44). Each of the plurality of clamp assemblies (104) clamps the at least one damping ring (106) on the damping wall.
