Description

Die Erfindung bezieht sich auf einen Propeller mit innerhalb der Flügelspitzen liegendem Düsenring und bezweckt eine weitere Verbesserung des Vortriebswirkungsgrades derartiger Propeller.The invention relates to a propeller with within the wing tips lying nozzle ring and aims to further improve the propulsion efficiency such propeller.

Zu diesem Zweck werden gemäß der Erfindung vor und/oder hinter dem Propeller je eine feste Düse angeordnet, wobei die festen Düsen zusammen mit der rotierenden inneren Düse des Propellers eine Düse mit sich stetig verengendem Querschnitt bilden. Die dem Propeller zuströmenden Wassermassen werden hierdurch bis zum Austritt aus der hinteren festen Düse steigend beschleunigt. Innerhalb der vorderen festen Düse kann ein fester Gegenpropeller angeordnet werden, dessen Schaufeln so geformt sind, daß die Wasserfäden für eine Steigerung des Vortriebswirkungsgrades in Propellerdrehrichtung abgelenkt werden. Durch Anordnung eines festen Gegenpropellers in der hinteren festen Düse mit entsprechend geformten Schaufeln wird die den Wassermassen im Propellerkern erteilte Drehbewegung in Fahrtrichtung abgelenkt und die durch die Ablenkung auf die Schaufelflächen des festen hinteren Gegenpropellers wirksam werdenden Druckkomponente für die Vortriebsleistutig nutzbar gemacht. Anstatt je eine feste Düse finit innerem festem Gegenpropeller beidseits der rotierenden Düse anzuordnen, kann man naturgemäß jeweils auch nur eine Düse entweder vor oder hinter dem Propeller vorsehen.For this purpose, according to the invention in front of and / or behind the Propeller arranged a fixed nozzle, the fixed nozzles together with the rotating inner nozzle of the propeller a nozzle with a steadily narrowing cross-section form. The water masses flowing towards the propeller are thereby reduced to the outlet increasing acceleration from the rear fixed nozzle. Inside the front solid Nozzle can be placed a fixed counterpropeller, the blades of which are shaped are that the water threads for an increase in the propulsion efficiency in the direction of rotation of the propeller to get distracted. By arranging a fixed counterpropeller in the rear fixed Nozzle with appropriately shaped blades is used for the water masses in the propeller core issued rotary movement in the direction of travel and deflected by the deflection the vane surfaces of the fixed rear counterpropeller become effective pressure component made usable for the propulsion efficient. Instead of a fixed nozzle each finite inner A fixed counterpropeller on both sides of the rotating nozzle can of course be arranged Provide only one nozzle either in front of or behind the propeller.

Die Zeichnung zeigt ein Ausführungsbeispiel der Anordnung der festen Düsen mit innerem Gegenpropeller vor und hinter dem Düsenpropeller im Schnitt.The drawing shows an embodiment of the arrangement of the fixed Nozzles with internal counterpropeller in front of and behind the jet propeller in section.

Der treibende Propeller i hat die innere Düse 2. Vor der Düse 2 befindet sich die feste Düse 3 und hinter ihr die feste Düse 5. Die drei Düsen 2, 3, 5 bilden zusammen eine Düse mit sich stetig verengendem Querschnitt und stromlinienförmigem Wandungsverlauf, so daß die Wasserfäden vom Eintritt in die feste Vordüse 3 bis zum Austritt aus der festen Achterdüse 5 stetig beschleunigt werden. Innerhalb der Düse 3 ist ein fester Gegenpropeller, dessen Schaufeln q so geformt sind, daß das in die Düse 3 axial eintretende Wasser in dem für den Wirkungsgrad des Propellers vorteilhaftesten Winkel umgelenkt in die innere Düse 2 des treibenden Propellers i eintritt. Die Schaufeln 6 des innerhalb der festen Düse 5 liegenden festen Gegenpropellers sind so geformt, daß die aus der Düse 2 des treibenden Propellers i drehend austretenden Wassermassen durch die Schaufeln gerichtet werden und als gleichmäßiger Axialstrom die feste Düse in Fahrtrichtung verlassen. Die durch den Aufprall der drehenden Wasserfäden auf die festen Schaufeln 6 des Gegenpropellers in den Schaufeln 6 hervorgerufene Reaktion wirkt dabei zusätzlich mit einer Vortriebskomponente in Fahrtrichtung.The driving propeller i has the inner nozzle 2. Located in front of the nozzle 2 the fixed nozzle 3 and behind it the fixed nozzle 5. The three nozzles 2, 3, 5 form together a nozzle with a steadily narrowing cross-section and a streamlined one Wall course, so that the threads of water from the entry into the fixed pre-nozzle 3 to to exit from the fixed figure eight nozzle 5 are steadily accelerated. Within the Nozzle 3 is a fixed counterpropeller, the blades of which q are shaped so that the in the nozzle 3 axially entering water in the for the efficiency of the propeller most advantageous angle deflected into the inner nozzle 2 of the driving propeller i enters. The blades 6 of the fixed counterpropeller lying within the fixed nozzle 5 are shaped so that the rotating exit from the nozzle 2 of the driving propeller i Masses of water are directed through the blades and as a uniform axial flow leave the fixed nozzle in the direction of travel. The by the impact of the spinning Threads of water on the fixed blades 6 of the counterpropeller in the blades 6 caused The reaction also acts with a propulsion component in the direction of travel.
