Abstract (en)

[origin: EP1577492A1] The rotor of a turbo machine in the exposed state has a control section (29) visible from the outside, and a monitoring section which is not visible from the outside. A weakened point in the fashion of a design break point is provided in the control section. When the machine is running, possible emerging damage of the rotor is recognized through a non-critical defect (39) emerging in the region of the weakened point (31) and propagating from this point. The weakened point is formed by a material weakening in the form of a notch (32). Independent claims are also included for the following: (A) a turbo machine equipped with the aforesaid rotor; and (B) a method for the recognizing of the state of the exposed rotor of a turbo machine.
