Abstract

PURPOSE: To make the wake distribution in the circumferential direction of the propeller uniform by extending the upper half of the nozzle forward edge to the forward of the nozzle at the hull equipped with a nozzle propeller.
CONSTITUTION: The upper half of the forward edge of a nozzle 1 is extended forward and is attached to an outer plate of the hull's stern, the attaching angle of said nozzle extension part 1' is set to match the water flow along the outer plate 5 or to have a slight sttack angle to said water flow. By forming the nozzle extension part 1' integrally with the nozzle 1, the water flowing along the lower surface of the nozzle extension part 1' is accelerated and flows into the upper part of the propeller 3 to make the wake distribution at the propeller position uniform, and the propeller cavitation and tip vortex are reduced.
