    Schraubenflügelrad.   



   Gegenstand der Erfindung ist ein   Schraubenflügelrad   zum Antriebe verschiedener Fahrzeuge, insbesondere von Wasser-oder Luftfahrzeugen, das derart ausgebildet ist, dass bei schneller Rotation des Schraubenrades durch die Zentrifugalkraft das Medium, in welche.. as Fahrzeug sich bewegt, in einer steilen Spirale zwischen dem Flügelrade und   minera..     JohÅal1se zwangläufig   ausgeworfen wird. Um hiebei den Querschnitt der bewegten ; Luft-oder Wassersäule zu vergrössern und die Wirbelbildung zu vermindern, ist   gemässe   der Erfindung das Flügelrad von einem Gehäuse umschlossen, in dem Leitschaufeln vor-1 gesehen sind, die die Schraubenflächen des Flügelrades senkrecht schneiden. 



   In der Zeichnung ist eine beispielsweise Ausführungsform der Erfindung zur Darstellung gebracht, in welcher Fig. 1 einen lotrechten Schnitt, Fig. 2 eine Draufsicht und Fig. 3 eine schaubildliche Ansicht veranschaulichen. 



   An der Welle a ist das Flügelrad b in bekannter Weise angeordnet, das von einem   Gehäuse c umschlossen   ist. An der inneren Mantelfläche des Gehäuses c sind Leitschaufeln d vorgesehen, die derart gekrümmt sind, dass sie die Schraubenflächen des Flügelrades senkrecht schneiden. 



   Wird das Flügelrad in rasche Rotation versetzt, so wird der Strom des Mediums, in welchem sich das mit der   Flugelschraube ausgertstete   Fahrzeug bewegt, gezwungen, sich zwischen der Achse und dem Gehäuse hindurch zu bewegen. Durch die bei der raschen Rotation erzeugte Fliehkraft wird   sohin   die Säule des Mediums zwischen den Leitschaufeln in einer gestreckten Spirale   zwangläufig   ausgeworfen. 

**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

    Screw impeller.



   The subject of the invention is a helical vane wheel for driving various vehicles, in particular watercraft or aircraft, which is designed in such a way that when the helical wheel rotates rapidly due to the centrifugal force, the medium in which the vehicle moves in a steep spiral between the Vane and minera .. JohÅal1se is inevitably ejected. To hiebei the cross-section of the moving; According to the invention, to enlarge the air or water column and to reduce the formation of eddies, the impeller is enclosed by a housing in which guide vanes are seen which intersect the helical surfaces of the impeller perpendicularly.



   In the drawing, an exemplary embodiment of the invention is shown, in which FIG. 1 shows a vertical section, FIG. 2 shows a plan view and FIG. 3 shows a perspective view.



   On the shaft a, the impeller b is arranged in a known manner, which is enclosed by a housing c. On the inner lateral surface of the housing c, guide vanes d are provided which are curved in such a way that they intersect the helical surfaces of the impeller perpendicularly.



   If the impeller is set in rapid rotation, the flow of the medium in which the vehicle equipped with the wing screw is moving is forced to move between the axle and the housing. Due to the centrifugal force generated during the rapid rotation, the column of the medium between the guide vanes is inevitably ejected in an elongated spiral.
