Abstract

Beschrieben wird eine Dichtungsanordnung zur Reduzierung von Leckströmen innerhalb einer Strömungsrotationsmaschine, vorzugsweise einer axialen Turbomaschine, mit Lauf- und Leitschaufeln, die jeweils in wenigstens einer Lauf- bzw. Leitschaufelreihe angeordnet sind und Schaufelfüsse aufweisen, über die die einzelnen Lauf- und Leitschaufeln mit Befestigungskonturen verbunden sind.
Die Erfindung zeichnet sich dadurch aus, daß zwischen wenigstens zwei benachbarten Schaufelfüßen innerhalb einer Leit- oder Laufschaufelreihe oder zwischen Leit- und/oder Laufschaufeln und benachbarten Komponenten der Strömungsmaschine ein filzartiges Material aufweisendes Dichtelement vorgesehen ist.
