Abstract

See full text

A propeller nozzle for watercraft, includes a nozzle and a propeller having at least one propeller blade which can rotate about a propeller axis and which spans a propeller area through rotation about the propeller axis. The propeller blade has a propeller blade end region wherein the propeller is disposed inside the nozzle in such a manner that a circumferential gap in the circumferential direction of the propeller nozzle is formed between the propeller end region and the inner wall of the nozzle. A marginal flow running from a nozzle in the area of the inner wall of the nozzle can flow through the gap, wherein the performance losses which occur due to turbulence of the marginal flow during flow around the propeller blade end region are kept as low as possible. Flow guiding apparatus guides at least one part of the marginal flow onto the propeller area.
