<P>PROBLEM TO BE SOLVED: To provide a simple and cost-effective system by which a CMC blade can be fitted to a metal turbine rotor or a disk. <P>SOLUTION: A composite turbine blade assembly 10 includes: a ceramic blade 12 including an airfoil portion 13, a shank portion 14 and an attachment portion 16; and a transition assembly 18 configured to attach the ceramic blade 12 to the turbine disk or the rotor, the transition assembly including first and second transition components 20, 22 clamped together, trapping the ceramic blade 12 therebetween. Interior surfaces of the first and second transition components 20, 22 are formed to mate with the shank portion 14 and the attachment portion 16 of the ceramic blade 12, and exterior surfaces of the first and second transition components 20, 22 are formed to include an attachment feature enabling the transition assembly 18 to be attached to the turbine rotor or the disk. <P>COPYRIGHT: (C)2012,JPO&INPIT |
