Abstract

Eine Gasturbine mit zumindest einer Turbinenstufe (1), die ein Turbinengehäuse mit einem Hitzeschild (4) mit Honeycombs (5) aufweist, wobei die Turbinenlaufschaufeln (7) der Turbinenstufe (1) ein Deckband (2) mit Dichtungsfinnen (3) aufweisen, ist dadurch gekennzeichnet, dass im Bereich der Honeycombs (5) eine Vorrichtung zur diskontinuierlichen Kühlung vorgesehen ist, die bei Überschreiten einer Maximaltemperatur an den Honeycombs (5) eine Kühlluftzufuhr bewirkt. Dabei ist die erfindungsgemäße Vorrichtung hochtemperaturresistent, mechanisch einfach aufgebaut und weist Fail-Safe-Eigenschaften auf.
