Abstract: A rotor blade (14) for a rotor assembly (10) is provided that includes a root (18), an airfoil (20), and a damper (24). The airfoil (20) has a length, a base (28), a tip (30), a first side wall (36,38), a second side wall (38,36), and at least one cavity (40). The length extends the base (28) and the tip (30). The at least one cavity (40) is disposed between the side walls (36,38), and the channel (42) is defined by a first wall portion (54) and a second wall portion (56). The damper (24), which is selectively received within the channel (42), includes a first bearing surface (80), a second bearing surface (82), a forward surface (76), and an aft surface (78), all of which extend lengthwise. At least one of the surfaces is shaped to form a lengthwise extending passage (92) within the channel (42). The passage (92) has a flow direction oriented along the length of the at least one surface to permit cooling air travel along the at least one surface in a lengthwise direction. According to one aspect of the present invention, the damper (24) has an arcuate lengthwise extending centerline (71).

Abstract: A rotor blade for a rotor assembly is provided that includes a root, an airfoil, a platform and a damper. The airfoil has at least one cavity. The platform is disposed between the root and the airfoil. The platform includes an inner surface, an outer surface, and a damper aperture disposed in the inner surface. The damper has a body a nd a base. The base and the damper aperture have mating geometries that enable the base to rotate within the damper aperture without substantial impediment from the mating geometries.

Abstract: A rotor blade damper (48) is provided that includes a body (58) having a base (60), a tip (62), a first contact surface (64), a second contact surface (66), a trailing edge surface (68), and a leading edge surface (70). The trailing edge and the leading edge surfaces (68,70) extend between the contact surfaces (64,66). The first contact surface (64), second contact surface (66), trailing edge surface (68), and leading edge surface (70) all extend lengthwise between the base (60) and the tip (62). The body (58) includes at least one cooling aperture (82) disposed adjacent the base (60), that has a diameter that is approximately equal to or greater than the width of the trailing edge surface (68) adjacent the tip (62). The body (58) tapers between the base (60) and the tip (62) such that a first widthwise cross-sectional area adjacent the base (60) is greater than a second widthwise cross-sectional area adjacent the tip (62).

The airfoil (20) has a length, a base (28), a tip (30), a first side wall (36,38), a second side wall (38,36), and at least one cavity (40). The length extends the base (28) and the tip (30). The at least one cavity (40) is disposed between the side walls (36,38), and the channel (42) is defined by a first wall portion (54) and a second wall portion (56). The damper (24), which is selectively received within the channel (42), includes a first bearing surface (80), a second bearing surface (82), a forward surface (76), and an aft surface (78), all of which extend lengthwise. At least one of the surfaces is shaped to form a lengthwise extending passage (92) within the channel (42). The passage (92) has a flow direction oriented along the length of the at least one surface to permit cooling air travel along the at least one surface in a lengthwise direction. According to one aspect of the present invention, the damper (24) has an arcuate lengthwise extending centerline (71).
