... to the commonly used control systems such as the Variable Geometry Turbine (VGT). This advantage makes the MC applicable for a wider range of applications which is difficult to be covered with the common control systems. Replacing the traditional spiral casing with the MC affects the blade's vibration behavior...

... of these mode localization effects depending on various parameters of a real high pressure compressor blisk rotor. The investigations show that blade vibration modes with lower interblade coupling, e.g., torsion modes or modes with high numbers of nodal diameter lines, have a significantly higher sensitivity...
