Abstract

Die Erfindung betrifft eine Leitschaufel für eine Gasturbine, insbesondere eine Niederdruckturbine, mit einem Schaufelblatt, das sich zwischen einer inneren Plattform und einer äußeren Plattform erstreckt, wobei die äußere Plattform Befestigungsmittel zur Anbringung an einem Gehäuse aufweist, und wobei wenigstens eine von der äußeren oder inneren Plattform an einer ersten Stirnfläche einen Vorsprung mit vorstehender Seitenfläche aufweist und an einer zweiten, gegenüberliegenden Stirnfläche eine Aufnahme zum formschlüssigen Aufnehmen eines Vorsprungs einer benachbarten Leitschaufel aufweist, deren Dimensionierung so auf den Vorsprung abgestimmt ist, daß die Plattformen benachbarter Leitschaufeln im montierten Zustand fluchten, ein Leitschaufelsegment aus wenigsten drei Leitschaufeln sowie einen Leitkranzverbund.
