Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Gegenstand der Erfindung ist ein vor einem Schraubenpropeller angebrachter Leitpropeller. Die Blätter des Leitpropellers sind nach der Erfindung so geformt, daß sie dem der Schraube zufließenden Wasser- oder Luftstrom eine Drehgeschwindigkeit entgegen der Schrauben drehrichtung erteilen. Die Größe der Drehgeschwindigkeit, die jedem Wasser- oder Luftteilchen erteilt wird, ist gleich oder nahezuThe subject of the invention is a leading propeller mounted in front of a screw propeller. The blades of the leading propeller are shaped according to the invention so that they match that of the screw inflowing water or air flow a speed of rotation opposite to the direction of rotation of the screws To give. The magnitude of the rotational speed that each particle of water or air has granted is equal or close to

ίο gleich der Drehgeschwindigkeit, die diese Teilchen beim Durchgang durch die Schraube erhalten würden, wenn kein Luftpropeller vorgesehen wäre. Hierdurch soll ein zur Schraubenachse paralleler Austritt der Wasser- oder Luftteilchen bewirkt werden, indem die erwähnten beiden entgegengesetzt gerichteten Geschwindigkeiten sich aufheben, so daß sich bei kleinstem Verlust ein Maximum der Reaktionswirkung ergeben wird. Die einzelnen Flügel, deren Zahl nicht begrenzt ist, sind hierbei auf der Wellenhose einzeln mit Flanschen befestigt. Ihre Befestigung kann auch in irgendeiner anderen Weise, z. B. unmittelbar an der Schiffshaut oder am Steven erfolgen; sie dienen dann gleichzeitig zur Versteifung des Austrittswellenlagers.ίο equal to the speed of rotation that these particles have would be obtained when passing through the screw if no air propeller was provided were. This is intended to be an exit parallel to the screw axis of the water or Air particles are caused by the aforementioned two oppositely directed Velocities cancel each other out, so that with the smallest loss there is a maximum of the reaction effect will result. The individual wings, the number of which is not limited, are individually flanged on the wave pants attached. Their attachment can also be done in some other way, e.g. B. immediately be carried out on the hull or on the stem; they then serve at the same time for stiffening of the output shaft bearing.

Alle Arme der Lagerböcke oder sonstigen Teile am Hinterschiff können dem Zweck des Leitapparates angepaßt und entsprechend ausgebildet werden. Endlich können die Flügel auf einer besonderen Nabe angebracht werden.All arms of the bearing blocks or other parts at the rear of the ship can serve the purpose of Diffuser adapted and trained accordingly. Finally the wings can be mounted on a special hub.

Claims (1)

Patent-Anspruch :Patent claim: Leitvorrichtung (Leitpropeller) vor einem Schraubenpropeller, dadurch gekennzeichnet, daß die Austrittskanten der Flügel der Leitvorrichtung der Drehrichtung des Schraubenpropellers entgegen geneigt sind, so daß der zufließende Wasser,- oder Luftstrom eine Drehung erhält, deren Richtung dem Drehsinn der Schraube entgegengesetzt ist und deren Größe gleich oder nahezu gleich der Drehgeschwindigkeit ist, die der Schraubenpropeller dem Wasser- oder Luftstrom um seine Drehachse erteilt.Guide device (guide propeller) in front of a screw propeller, characterized in that that the trailing edges of the blades of the guide device are inclined against the direction of rotation of the screw propeller, so that the incoming water or air stream receives a rotation, its direction the direction of rotation of the screw is opposite and its size is the same or almost the same is the same as the speed of rotation that the screw propeller moves with the flow of water or air issued around its axis of rotation.
