Abstract

Die Erfindung betrifft ein Turbinenleitrad einer Gasturbine mit mehreren um den Umfang beabstandet angeordneten Leitschaufeln. Dabei ist vorgesehen, dass zwei benachbarte Leitschaufeln (23) jeweils zwischen der Saugseite (31) der einen Leitschaufel (23) und der Druckseite (30) der anderen Leitschaufel ausgehend von der Schaufelhinterkante (32) eine Passage (29) ausbilden, welche einen konstanten Passagenabschnitt (29a) umfasst, in dem die Passage (29) einen im Wesentlichen konstanten Passagenquerschnitt (37) aufweist. Der konstante Passagenabschnitt (29a) weist einen Eintrittsbereich (38) und einen Austrittsbereich (36) auf. Jede Leitschaufel (23) bildet druckseitig einen hinteren Bereich (320) aus, der sich ausgehend von der Schaufelhinterkante (32) angrenzend an den konstanten Passagenabschnitt (29a) bis zum Eintrittsbereich (38) des Passagenabschnitts (29) erstreckt, und bildet druckseitig einen vorderen Bereich (310) aus, der sich stromaufwärts des hinteren Bereichs (320) erstreckt. Es ist vorgesehen, dass jede Leitschaufel (23) auf der Druckseite (30) eine konvexe Druckseitenkontur (33) aufweist, die einen Übergang vom hinteren Bereich (320) der Leitschaufel (23) zum vorderen Bereich (310) der Leitschaufel (23) herstellt.
