Abstract

Am freien Ende der Propellerflügel ist eine Schutzplatte (2) vorgesehen; die Schutzplatte weist - in Schnitten (a,b,c) senkrecht zur Achse zwischen den Extremlagen des Steuerpunktes - im Bereich um die Schnittebene durch die Extremlage des Steuerpunktes für Vorausfahrt in Fahrtrichtung vorn eine starke Profilierung auf;
die Schutzplatte (2) weist im Bereich um die Schnittebene durch die Extremlage des Steuerpunktes für Rückwärtsfahrt in Rückwärtsfahrtrichtung vorn eine starke Profilierung von etwa gleicher Größe auf.

Figure 00000001
A protective plate (2) is provided at the free end of the propeller blades; the protective plate has - in sections (a, b, c) perpendicular to the axis between the extreme positions of the control point - a strong profile in the area around the section plane due to the extreme position of the control point for driving ahead in the direction of travel;
The protective plate (2) has a strong profile of approximately the same size in the area around the cutting plane due to the extreme position of the control point for backward travel in the backward direction of travel.
