Ship with at least one propeller - nozzle with an optimally associated rudders

摘要

A marine vessel propulsion assembly includes at least one propeller nozzle unit having a rudder associated with it. The propeller nozzle unit has a shroud laterally surrounding the propeller and the shroud is supported so that it can be pivoted about two different axes each extending transversely of the flow direction. In the desired angular position, the shroud can be locked in position. The two pivot axes of the shroud extend perpendicular to one another. The shroud is connected to a shaft extending in the direction of one of the pivot axes and the shaft can be interlocked with shaft guide means. The shroud and the rudder each include the same angle of pitch of at least two degrees relative to the propeller shaft.
