PROBLEM TO BE SOLVED: To provide an effective shim in a rotor assembly of a turbo machine having a rotor disk, a blade, and the shim attached between a blade root part and the rotor disk. SOLUTION: In this rotor assembly of a turbo machine, each shim 20 comprises two branch parts 20A and a bottom part 20B connecting the branch parts to each other. Each branch part 20A is disposed between the support surface 16A of the blade root part 16 and the corresponding support surface 22A of the disk 2. Each branch part 20A is formed of a first material having a first Young's modulus E at any operating temperature within the operating temperature range of the shim 20. The rotor assembly includes a pad 40 adhered to the support surface 22A of the disk and/or the support surface 16A of the blade root part. The pad 40 is formed of a second material having a second Young's modulus within the range of E/20-E/5 at the operating temperature. COPYRIGHT: (C)2009,JPO&INPIT
