A MARINE PROPULSION SET COMPRISING A POD DESIGNED TO BE INSTALLED UNDER THE HULL OF A SHIP

摘要

An engine assembly (1, 1', 1 ) including at least one pod (2) connected to a supporting leg (3, 3', 3 ), a propeller (4) with at least two blades (14) located at the back of the pod, and an arrangement of at least three flow-directing fins (50-55, 3'A) attached to the pod (2). The fin arrangement forms a ring (5) substantially perpendicular to the longitudinal axis (X) of the pod (2), which ring is within an area (Zx) located between the central portion of the supporting leg (3, 3', 3 ) and the propeller. The assembly further includes a nozzle (6) around all or part of the propeller and said ring (5). The blades (14) each have one end of which one edge (7) is flush with the inner wall of the nozzle (6) so that the propeller (4) acts as the impeller of an axial-flow pump. ® KIPO & WIPO 2007
