Abstract

Ein Verfahren zum Abstimmen einer Kompressorstatorschaufel (28), die einen Basisabschnitt (30) und einen Blattabschnitt (32) aufweist, um eine gewünschte Eigenfrequenz zu erzielen, beinhaltet die Schritte: a) Identifizieren der Eigenfrequenz der Kompressorstatorschaufel; b) Ermitteln einer abweichenden angestrebten Eigenfrequenz für die Kompressorstatorschaufel und c) Entfernen von Material aus dem Basisabschnitt (30) der Kompressorstatorschaufel in einer Menge und in einer Konfiguration, die geeignet sind, die angestrebte Eigenfrequenz zu erzielen. Eine frequenzabgestimmte Kompressorstatorschaufel (28) weist einen Blattabschnitt (32) und einen Basisabschnitt (30) auf, wobei der Basisabschnitt eine im Wesentlichen starre Rechteckform aufweist und eine Nut (34) aufweist, die quer über eine Breitendimension des Basisabschnitts (30) ausgebildet ist, wobei die Nut Abmessungen aufweist, die ausgewählt sind, um für den Blattabschnitt eine vorbestimmte Eigenfrequenz zu erreichen.
