Abstract

Die Erfindung betrifft eine Gasturbine mit einer Leitschaufel (20), welche Leitschaufel (20) an einem Schaufelträger (38) befestigt ist und ein sich in radialer Richtung von einer Deckplatte (21) aus nach innen in einen Heissgaskanal (44) erstreckendes Schaufelblatt (22) umfasst, durch dessen Inneres ein Kühlmedium, insbesondere Kühlluft, strömt, das durch einen Zugang (43) im Schaufelträger (38) in ein oberhalb der Deckplatte (21) angeordnetes erstes Plenum (41) und von dort über einen in der Deckplatte (21) vorgesehenen Einlass (36) in das Innere des Schaufelblattes (22) einströmt. Bei einer solchen Schaufel wird eine vereinfachte Kühlung der Deckplatte (21) dadurch erreicht, dass erste Mittel (34, 35; 35a, 43) zur Steuerung des Kühlmediumdrucks in dem ersten Plenum (41) vorgesehen sind, und dass zweite Mittel (42, 45, 46) vorhanden sind, welche eine Kühlung der Deckplatte (21) durch gezielt aus dem ersten Plenum (41) entweichendes Kühlmedium bewirken.
