Abstract

Bei einer Rotorwelle (10), insbesondere für eine Gasturbine, sind Kühlluftkanäle (14) vorgesehen, die im wesentlichen in radialer Richtung von innen nach aussen verlaufen und mit einer im Inneren der Rotorwelle (10) vorhandenen Kühlluftzuführung (16) in Verbindung stehen.
Eine Verbesserung der mechanischen Eigenschaften der Rotorwelle wird dadurch erreicht, dass die Kühlluftkanäle (14) zur Verminderung von mechanischen Spannungen einen elliptischen Querschnitt aufweisen.
