A blade-to-blade vibration damper for a turbine rotor blade is disclosed. Each blade has airfoil, platform and root portions. A plurality of blades are circumferentially spaced about a rotor disk. An inclined recess extends into the platform portion of each blade from a first surface thereof, and toward its root portion. A U-shaped wire-form damping member has its in-turned marginal end portions slidably received in each recess. When the rotor disk is rotated at a sufficient angular speed, the damping members move outwardly by the centrifugal force actin...
An improved rotor blade adapted to be mounted on a rotor disk in circumferentially spaced relation to an adjacent blade, said improved blade comprising: an airfoil portion, a platform portion and a root portion, said platform portion having a first surface adapted to be arrange din spaced facing relation to an opposing surface of said adjacent rotor blade, said improved blade also having an arcuate surface extending between said root portion and said first surface, said arcuate surface being bowed outwardly in a transverse direction; two transversely spa...
