Abstract: The present invention relates to a method for monitoring the creep behavior of rotating components of a compressor stage or turbine stage. In the method, at least one test element (2) is mounted in a region of the compressor stage or turbine stage in which the test element is exposed to an operating load comparable to that of the component to be monitored. The test element (2) is investigated after a predeterminable operating period of the component to be monitored. Finally, the creep behavior of the component to be monitored is derived from the creep behavior of the test element. The method makes it possible to detect exactly the creep behavior or creep damage of the component to be monitored, during the useful life of this component.

Abstract: The rotor blades of a turbomachine are fastened to the rotor (3) of the machine by means of blade roots (1) by the blade roots (1) being anchored in peripheral grooves (2). According to the invention, the blade roots (1) have at least one recess or opening (4), which extends in the peripheral direction and in each of which a connecting piece (5) is arranged. This connecting piece (5) connects at least two blade roots (1) to form a blade pack. By means of the connection, the blade roots (1) are secured against twisting and falling out of the peripheral groove (2). The connecting piece (5) consists of a shaped piece, which is laid with little clearance into the recess or opening (4), a displacement of a blade root (1) and of the connecting piece (5) relative to one another still being possible. The blade root of the last blade of a blade row which is assembled in a peripheral groove is locked to the adjacent blade roots by a final connecting piece.
