A turbine blade comprising: a hollow airfoil joined to a platform and dovetail; a main flow channel extending longitudinally in span from an inlet in said dovetail to a tip end of said airfoil, and bound chordally by opposite forward and aft partitions transversely bridging opposite sidewalls (20,22) of said airfoil; said main flow channel including a damper rib extending inwardly from one of the opposite sidewalls; and a wire damper; characterised in that: the wire damper is longitudinally oriented inside the main flow channel, and in that the turbine blade further comprises: a damper pad transversely opposite the damper rib, the damper pad extending inwardly from the other of the opposite sidewalls, wherein the damper rib converges aft with the transversely opposite damper pad to define a v-profile bearing surface for wedging of the wire damper therewith under centrifugal loading of the blade, the damper rib and the damper pad being longitudinally oriented and arranged together in a plurality of pairs spaced apart longitudinally in said airfoil and chordally positioned intermediate said partitions to provide unobstructed forward and aft portions of said main flow channel for channeling a coolant therethrough. a hollow airfoil joined to a platform and dovetail; a main flow channel extending longitudinally in span from an inlet in said dovetail to a tip end of said airfoil, and bound chordally by opposite forward and aft partitions transversely bridging opposite sidewalls (20,22) of said airfoil; said main flow channel including a damper rib extending inwardly from one of the opposite sidewalls; and a wire damper; characterised in that: the wire damper is longitudinally oriented inside the main flow channel, and in that the turbine blade further comprises: a damper pad transversely opposite the damper rib, the damper pad extending inwardly from the other of the opposite sidewalls, wherein the damper rib converges aft with the transversely opposite damper pad to define a v-profile bearing surface for wedging of the wire damper therewith under centrifugal loading of the blade, the damper rib and the damper pad being longitudinally oriented and arranged together in a plurality of pairs spaced apart longitudinally in said airfoil and chordally positioned intermediate said partitions to provide unobstructed forward and aft portions of said main flow channel for channeling a coolant therethrough. the wire damper is longitudinally oriented inside the main flow channel, and in that the turbine blade further comprises: a damper pad transversely opposite the damper rib, the damper pad extending inwardly from the other of the opposite sidewalls, wherein the damper rib converges aft with the transversely opposite damper pad to define a v-profile bearing surface for wedging of the wire damper therewith under centrifugal loading of the blade, the damper rib and the damper pad being longitudinally oriented and arranged together in a plurality of pairs spaced apart longitudinally in said airfoil and chordally positioned intermediate said partitions to provide unobstructed forward and aft portions of said main flow channel for channeling a coolant therethrough. a damper pad transversely opposite the damper rib, the damper pad extending inwardly from the other of the opposite sidewalls, wherein the damper rib converges aft with the transversely opposite damper pad to define a v-profile bearing surface for wedging of the wire damper therewith under centrifugal loading of the blade, the damper rib and the damper pad being longitudinally oriented and arranged together in a plurality of pairs spaced apart longitudinally in said airfoil and chordally positioned intermediate said partitions to provide unobstructed forward and aft portions of said main flow channel for channeling a coolant therethrough.
