Abstract:
A rotor blade (14) for a rotor assembly (10) is provided that includes a root (180, an airfoil (20), and a damper (24). The airfoil (20) includes a base (28), a tip (30), a pressure side wall (36), a suction side wall (38), and a cavity (40) disposed therebetween. The cavity (40) extends substantially between the base (28) and the tip (30), and includes a first cavity portion (44), a second cavity portion (46), and a channel (42) disposed between the first cavity portion (44) and the second cavity portion (46). A plurality of first pedestals (48) are disposed within the first cavity portion (44) adjacent the channel (42), and a plurality of second pedestals (48) are disposed within the second cavity portion (46) adjacent the channel (42).
