Document Type and Number:
Japanese Patent JP6376679
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a stern duct capable of improving a hull efficiency without increasing the resistance to a hull even if a duct body is added to the hull, a method for designing the stern duct, and a ship equipped with the stern duct.SOLUTION: A stern duct is characterized: in that a duct body 11 is formed into a generally arcuate shape of an angular range from 90 degrees to 180 degrees in a stern duct 10 to be attached to the front of a propeller 3 attached to the stern 2 of a hull; and in that the duct body 11 is so attached to the stern 2 by support means 12 that the duct body 11 may be asymmetric to the vertical center line Xv of the propeller 3 while the hull is seen in a front view.
