Abstract: PROBLEM TO BE SOLVED: To constitute a rotor for turbomachinery in such a way as to avoid the defects of convensional technique so as to reach an operating state in an extremely short time and to be thermally adjustable in an easy way, that is, in such a way as to be heated and cooled in a relatively short time according to a demand. SOLUTION: At least two pipes 8, 9 with mutually different diameters and length are arranged in a cylindrical hollow part 7. These pipes 8, 9 are overlapped at least partially in the fixed length, and the openings of the different pipes 8, 9 are overlapped in a turbine part 4 at the time of a high temperature operating state and overlapped in a compression part 2 and a center part 3 at the time of a low temperature state.
