Abstract:
An integrally bladed turbine disk assembly comprising:an integrally bladed turbine disk having a plurality of radially outwardly extending turbine blades and at least one damper aperture, each of the plurality of turbine blades terminating at a distal end in a circumferentially extending tip shroud, the at least one damper aperture being formed between two adjacent tip shrouds and including a first slotted portion and a second slotted portion, the first slotted portion being incorporated concentrically into the two adjacent tip shrouds, the second slotted portion extending radially outwardly between the two adjacent tip shrouds; and a damper member disposed in the first slotted portion of the at least one damper aperture, the damper member frictionally engagable with at least one surface of each of the two adjacent tip shrouds to dissipate energy in the two adjacent tip shrouds to dampen vibration.
