Abstract
The present invention relates to a propulsion unit nozzle for being arranged around a propeller in a propulsion unit, comprising: a load bearing core structure extending in a circumference of the propulsion unit nozzle; and a plurality of hydrodynamic elements mounted on and enclosing the core structure thereby defining the outer and the inner surfaces of the propulsion unit nozzle. The invention further relates to a propulsion unit for a vessel comprising a propulsion unit nozzle and to a method for the manufacture of a propulsion unit nozzle.
Claims19
A propulsion unit nozzle for being arranged around a propeller in a propulsion unit, the propulsion unit nozzle being defined by an outer surface and an inner surface, wherein the propulsion unit nozzle comprises:
- a load bearing core structure extending in a circumference of the propulsion unit nozzle between the outer surface and the inner surface;
- and
- a plurality of hydrodynamic elements mounted on and enclosing the load bearing core structure thereby providing the outer surface and the inner surface of the propulsion unit nozzle, wherein the plurality of hydrodynamic elements are of a varying geometry, wherein each of the plurality of hydrodynamic elements extends along the entire width of the propulsion unit nozzle, wherein one or more of the plurality of hydrodynamic elements comprises a leading part and a trailing part adapted to be assembled on the load bearing core structure to provide a hydrodynamic element and wherein each of the plurality of hydrodynamic elements comprises an exterior indentation providing an outer track extending along the periphery of the outer surface of the propulsion unit nozzle, the outer track being adapted for receiving an exterior fastening element.
