WIPO Patent Application WO/2018/025644
Kind Code:
A1
Abstract:
Provided is a ship 1 in which stern ducts 10A-10E, each having a duct member 11 and a duct support member 12 for supporting the duct member 11 on a ship hull 2, are disposed immediately before a propeller 3, wherein a rear edge of the duct member 11 which is located above the center C of a propeller rotating axis as viewed from a bow-stern direction is configured to have a shape formed so as to include a portion of an elliptical shape that has the minor axis oriented in the ship width direction and the major axis oriented in the water depth direction. This configuration allows a ship having stern ducts disposed immediately before a propeller to have the thrust generation portion of the stern duct, which contributes to generating thrust by utilizing a slipstream of the ship hull, formed in a much greater size as compared with a stern duct in a circular arc shape, and thus enables an increase in the thrust generated by the stern duct.
