Abstract (en)
[origin: EP2277772A1] The propeller (100) has a shaft axle (11) supported on a shaft bearing (13), and multiple tail fins forming an asymmetric fin-system. Each tail fin forms a stator attached to an inner wall surface of a fixed nozzle (10) at an end and attached to the shaft bearing at another end. The fin-system is asymmetrically arranged in an inner chamber of the nozzle, such that individual tail fins are different in length. A section (14a) of each tail fin extends into the inner chamber of the nozzle, and another section (14b) of each tail fin projects from an outer region of the nozzle.
