Abstract

A rotor disk assembly (60) for a gas turbine engine (20) includes a rotor disk (86) that defines an axis; and a damper pivot support (112) that extends from a rim (106) of the rotor disk (86), the damper pivot support (112) comprising an aperture (114) that defines a pivot axis (T) parallel to the axis. A method to dampen a rotor blade (84) of a gas turbine engine (20), includes pivotably mounting a damper assembly (126) to a damper pivot support (112) that extends from a rim (106) of a lug (110) in a rotor disk (86), the lug (110) between a first blade slot (94) and a second blade slot (94), the damper pivot support (112) defines a pivot axis (T) parallel to the axis; and independently pivoting a first damper (120) and a second damper (122) of the damper assembly (126) about the pivot axis (T) to respectively contact a first blade (84A) and a second blade (84B) in response to centrifugal force, a first contact surface (130) of the first damper (120) and a second contact surface (132) of the second damper (122) contacting the respective blades (84A, 84B) below a platform (90A, 90B) of the respective first blade (84A) and second blade (84B).
