The propeller nozzle (100) has a nozzle (10) and a propeller (20) with multiple propeller blades (22). A flow guiding unit is provided for directing a portion of the flow edge on the propeller surface, and is arranged in the immediate vicinity of a gap, particularly in the direction of flow in front of the gap. The flow guiding unit is formed circumferentially in the circumferential direction of the nozzle, and has a recovery in the inner wall of the nozzle. The recovery is formed as depression (15) in the inner wall of the nozzle. |
