Description

Im Gegensatz zu .den bekannten Druck- und Zugschiffspropellern (Schiffsschrauben) werden nach der Erfindung bei vierflügeligen Schiffspropellern zwei gegenüberliegende Flügel (ein Flügelpaar), bei dreiflügeligen Schiffspropellern sein Flügel zur Propellerachse geneigt angeordnet, und zwar bei Anordnung am Vorschiff als Zugpropeller nach vorn .geneigt in Fahrtrichtung und bei Anordnung am Hinterschiff als Druckpröp.eller nach hinten geneigt entgegengesetzt' zur Fahrtrichtung.In contrast to the well-known push and pull ship propellers (ship's propellers) are according to the invention with four-bladed ship propellers two opposite one another Wing (a pair of wings), with three-winged ship propellers its wing to the propeller axis arranged inclined, namely when arranged on the forecastle as a pulling propeller forward inclined in the direction of travel and when arranged at the stern as a pressure gauge inclined backwards opposite to the direction of travel.

Durch die geneigte Anbringungeines bzw. eines Flügels wird bewirkt d@aß sowohl bei Zug- als auch bei Druckschiffspropellern eine bedeutend bessere Leistung erzielt wird.The inclined mounting of a wing is effected d @ ate a significantly better one with both draft and pressure ship propellers Performance is achieved.

Fig. i stellt die Draufsicht auf einen vierflügeligen Schiffspropeller dar, bei' welchem alle vier Flügel gleich groß sind. Das Flügelpaar ,d ,erscheint im Verhältnis zum Flügelpaar c durch die Neigung zur Schraubennabe b kürzer. Fig. a stellt die Seitenansicht eines vierflügeligen Schiffspropellers, im Schnitt c-d dar, Hieraus ist die Neigung des Flügels d zur Nabe b ersichtlich.Fig. I shows the top view of a four-bladed ship's propeller, in which all four blades are the same size. The wing pair, d, appears shorter in relation to the wing pair c due to the inclination towards the screw hub b. Fig. A shows the side view of a four-winged ship's propeller, in section cd, from which the inclination of the wing d to the hub b can be seen.

Bei einem dreiflügeligen Schiffspropeller ist die Neigung eines Flügels zur Schraubennabe in gl:ei: cher Weise vorgesehen.On a three-bladed ship's propeller, the pitch of one of the blades is intended for the screw hub in the same way.
