Abstract

Die vorliegende Erfindung betrifft die Stufe einer Turbine oder eines Verdichters mit einer Mehrzahl von Schaufeln, die an einem Rotor und/oder einem Stator der Stufe montiert sind. Die Schaufeln sind erfindungsgemäß zu einer Anzahl von Schaufelclustern als integrale Bauteile zusammengefasst, die jeweils aus zumindest zwei Schaufeln bestehen und die jeweils mit einer einzigen gemeinsamen Schaufelbefestigung zur Montage des Clusters am Rotor oder Stator ausgestattet sind.
