Description
Schraubenpropeller mit Leitvorrichtung. Die Erfindung betrifft einen Schraubenpropeller mit Gegenpropeller, der dem Schraubenwasserstrahl in bekannter Weise eine möglichst achsiale Richtung geben soll, um die für die Fortbewegung des Fahrzeuges --Wasserselbstfahrers oder Luftfahrzeugesunwirksamen Tangentialkomponenten des Strahles möglichst nutzbar zu machen. Gleichzeitig sollen die sogenannten von der Spitze und von der Wurzel jedes Propeller-Rügels ausgehenden Spitzen- und Nabenwirbel beseitigt werden. Dazu sind Propeller wie Gegenpropeller ummantelt. Nun sind Anordnungen bekannt, bei denen der Propeller' in derselben festen Umhüllung läuft, in der auch der Gegenpropeller angebracht ist. Dadurch treten zwischen den Propellerflügeln und dem Mantel störende und hindernde Wirbel- und Spaltverluste ein. Außerdem ist durch den nach vorn zu über die Flügelbegrenzung hinaus sich erstreckenden Mantel der allseitige freie Zufiuß des Wasserstromes zum Propeller gehemmt. Auch das Aufbringen und Abnehmen des Propellers ist bei dieser Einrichtung erheblich behindert.Screw propeller with guide device. The invention relates to a Screw propeller with counterpropeller, which is known to the screw water jet Way should give as axial a direction as possible to the movement of the Vehicle - water self-propelled or aircraft with ineffective tangential components to make the beam as useful as possible. At the same time, the so-called von tip and hub vortices emanating from the tip and root of each propeller blade be eliminated. For this purpose, both propellers and counterpropellers are sheathed. Now are orders known, in which the propeller 'runs in the same solid envelope in which also the counterpropeller is attached. This step between the propeller blades and the jacket disturbing and hindering vortex and gap losses. Also is by the jacket extending forward beyond the wing boundary the all-round free inflow of the water flow inhibited to the propeller. The application and removal of the propeller is also significant with this device with special needs.
Um diese Nachteile unter Erhaltung der durch Mantel und Gegenpropeller "bedingten Vorteile zu vermeiden, wird bei der Vorrichtung gemäß der Erfindung die Schraube für sich mit einem Ring versehen, der von den äußersten Spitzen der Flügel aus sich nur nach hinten zu erstreckt. Der hinter der Schraube befindliche feststehende Gegenpropeller ist ebenfalls für sich mit einem flachen Ring ummantelt.To these disadvantages while maintaining the by jacket and counterpropeller "To avoid conditional advantages, in the device according to the invention Screw for itself provided with a ring, which from the extreme tips of the wings from only extending backwards. The fixed one behind the screw The counterpropeller is also covered by a flat ring.

I, 2 and 3 show an embodiment of the invention. a is the ring placed around the propeller blades b and rotating with them, c the counterpropeller ring, which is attached to the rudder post, with guide surfaces d.
