Abstract

Das technische Gebiet liegt auf dem Gebiet der Schuberzeugung durch Rückstoß eines Fluids. Aufgabe ist es unter anderem die Schuberzeugung effizient zu machen. Dies gelingt durch ein Triebwerksanordnung mit mindestens einem beschaufelten Rotor, auf welchen mindestens eine Antriebsleistung aufgekoppelt werden kann, mit der Folge, dass zumindest eine Druckänderung in einem Teil des Fluides hervorgerufen werden kann, mit der Folge, dass sich mindestens ein Fluidmassenstrom bewegen kann, wobei in mindestens einem der bewegten Fluidmassenströme mindestens eine Statoreinrichtung angeordnet ist, wobei diese Statoranordnung mindestens ein Blatt umfasst, welches im Einstellwinkel veränderbar ist, so, dass mindestens dieses in Bezug zur fluiddynamischen Strömung des mindestens einen beschaufelten Rotors so angeströmt werden kann, dass das Blatt eine resultierende Strömungskraft erzeugen kann, die eine Kraftkomponente in Richtung der resultierenden Saugkraft oder in Richtung der Drehachse des beschaufelten Rotors hat.
