<p>Nonmetallic airfoil blades (84) are mounted to a rotor disk (38) via a circumferentially spaced array of metal support members (66). Each support member (66) includes a pair or circumferentially spaced arcuate or airfoil shaped dovetail engagement surfaces (90,92). The metal support members (66) are secured to the rotor disk (38) via straight dovetails (68) while the rotor blades (84) are secured to the support members (66) via airfoil shaped dovetails (88). The support members (66) may include hollow portions (78) for channeling cooling air (39) to the airfoil blades (84). <IMAGE></p> |
