Abstract

Die vorliegende Erfindung betrifft eine Tandemschaufelkonstruktion für eine Axialströmungsmaschine bestehend aus einer vorderen sowie einer zu dieser im Umfangs- sowie in Axialrichtung versetzt angeordneten hinteren Schaufel. Die hintere Schaufel ist so profiliert und zur vorderen Schaufel positioniert, dass sie im vorbestimmten Arbeitsbereich in Wechselwirkung mit der vorderen Schaufel tretend das Geschwindigkeitsniveau an der Hinterkante der vorderen Schaufel anhebt.
