    Abstract: A rotor blade (44) having axially spaced gussets (72, 78) disposed between a root portion (66) and a platform (64) is disclosed. Various construction details are developed which provide a gusset providing both platform support and damper positioning means. In one particular embodiment, a rotor blade assembly (38) includes a plurality of circumferentially spaced rotor blades (44) having dampers (88) disposed between adjacent blades (44), wherein each blade (44) includes an axially spaced pair of gussets (78, 82) extending laterally from the rotor blade (44). The gussets (78, 82) extend from a root portion (66) of the rotor blade (44) to a platform (64) and provide radial support of the platform (64) during rotation of the rotor assembly (38). The gussets (78, 82) include a curved lateral edge which, during rotation of the rotor assembly (38), urges the damper (88) away from the root portion (66) of the blade (44).

    Abstract: An airfoil includes an airfoil body that has a leading edge and a trailing edge and a first sidewall and a second sidewall that is spaced apart from the first sidewall. The first sidewall and the second sidewall join the leading edge and the trailing edge and at least partially define a cavity in the airfoil body. A damper member is enclosed in the cavity and is loose within the cavity.
