Abstract (en)
[origin: EP0271039A2] The propulsion element has propeller blades (3) which are fastened to a propulsion spindle projecting out of the hull, are orientated at a certain angle thereto and are surrounded by a cylindrical shell (4). The propulsion element is characterized in that, on the propulsion spindle (1) at a distance (L) from the propeller blades (3) in the direction of the propulsion engine, vanes (5) having an at least partly curved profile extend in a helical arrangement up to the propeller blades (3) into the interior of the cylindrical shell and are fastened thereto in such a way that the water flow or water quantity in front of the area of the propeller blades is positively directed to the inside essentially in the direction of the propulsion spindle (1) and the propeller blades (3). <IMAGE>
