Abstract

Ein Rotor (11) einer thermisch belasteten Turbomaschine, insbesondere eines Kompressors (10) oder einer Gasturbine, ist um eine Rotorachse (21) drehbar gelagert und konzentrisch von einem Heissgaskanal (12) oder Kühlluftkanal umgeben. Eine deutliche Verbesserung der thermischen Belastbarkeit bei geringem materialtechnischem Mehraufwand wird dadurch erreicht, dass der Rotor (11) einen Rotorkern (22) aus einem ersten Material umfasst, dass der Rotorkern (22) konzentrisch von Abschirmringen (18) aus einem zweiten Material umgeben ist, welche den Rotorkern (22) gegen die Temperatur im Heissgaskanal (12) bzw. Kühlluftkanal abschirmen, wobei das zweite Material gegenüber dem ersten Material eine höhere Wärmefestigkeit aufweist, und dass die Abschirmringe (18) mit dem Rotorkern (22) stoffschlüssig verbunden sind.
