Abstract
A method for the nondestructive crack testing of surfaces of rotor blade-receiving blade reception slots of a rotor, includes the following steps: positioning a guide rail on a rotor surface section between two rotor blades; positioning an ultrasound test head oriented in the direction of at least one blade reception slot and is moveable in a manner guided along a trajectory predefined by the shape of the guide rail; moving the test head along the trajectory in the installed state of two adjacently arranged rotor blades and checking the surface of the blade reception slot for the presence of cracks using the ultrasound test head, wherein cracks that are present are detected in the form of data using the ultrasound test head; diagnosing the rotor state on the basis of the data.
