Abstract
A rotor of an axial-flow machine including a plurality of spacer members arranged peripherally of the rotor for providing a channel on the surface of the rotor. The spacer members are located in a manner to straddle the forward stage disc section and the rearward stage disc section, to enable each rotor blade to be replaced individually with a new one by mounting and removing the rotor blade axially of the rotor. The rotor of the axial-flow machine has improved reliability and flow performance.
