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.
The invention relates to a vane for a gas turbine, particularly a low pressure turbine, having a blade that extends between an inner platform and an outer platform, the outer platform having fasteners for attachment to a housing, and at least one of the outer or inner Platform has a projection with a protruding side surface on a first end face and has a receptacle on a second, opposite end face for positively receiving a projection of an adjacent guide vane, the dimensions of which are matched to the projection such that the platforms of adjacent guide vanes are aligned when assembled Guide vane segment consisting of at least three guide vanes and a guide ring assembly.Applications Claiming Priority (2)
