Abstract

Die Erfindung betrifft eine Strömungsmaschine mit passiver Laufschaufelverstellung. Kennzeichnend ist die kombinierte Verstellung von Anstellwinkel, Wölbung und Schränkung in sich biegeelastischer oder segmentierter Laufschaufeln (3, 4). Die passive Charakteristik wird auf konstruktivem Weg durch eine Zweipunktlagerung der Laufschaufeln auf der Maschinenwelle (1) und einem entlang eines Stellwegs frei beweglichen Schaufellagerring (2) erzielt. Die Stellkraft resultiert aus dem dynamischen Gleichgewicht zwischen Fliehkraft, Federmoment, Drehmoment und fluiddynamischem Moment. Dabei bildet eines der Lager (3a, 4a) den Drehpunkt und das andere den Fußpunkt des Stellvorgangs. Die Erfindung kann als axiale oder radiale Strömungsmaschine für alle üblichen Fluide sowie für einen Repeller- und einen Propellerbetrieb ausgeführt werden. Sie erzielt gegenüber bekannten ungeregelten oder nur den Anstellwinkel der Laufschaufeln regelnden Ausführungsformen eine deutliche Kennlinienverbesserung. Verbessert werden insbesondere Startverhalten, Leistungsdynamik und mittlere Leistung. Besonders deutlich kann die Erfindung ihre Vorteile in Meereswellen- (OWC-) und Gezeitenströmungskraftwerken entfalten. Weiteres Potenzial liegt im Bereich drehzahlgeregelter Arbeitsmaschinen mit besonderem Optimierungsbedarf.
