The prerequisite of the demand for a high degree of effectiveness over long periods of operation is that the clearance gap is minimized in all operating situations. This makes rubbing of rotor components much more likely, most of all in blade tips and the hub contour with housings and guide assemblies. Rubbing occurs with high relative…
