Abstract (en)

[origin: EP2090750A1] The rotor (1) has a rotor blade (2) provided with a blade base (4). A rotor disk (16) has a groove (17) in which the blade base is engaged such that the blade is held in the groove in a radial direction in a form-fit manner. Pre-tensioning devices (7-14, 19-28) are supported at the rotor disk and at the blade base, and exert a pre-tensioning force on the blade base in the radial direction. The pre-tensioning devices are designed such that the pre-tensioning force is adjusted when the rotor is in the assembled state. An independent claim is also included for a method for assembling a turbo machine rotor.
