Document Type and Number:
Japanese Patent JP6663144
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an air bubble removal device for air lubrication which maintains effects of an air lubrication method, in which air is jetted around a hull to reduce friction resistance, and rationally prevents harmful effects on the propeller efficiency from being caused by the jetted air bubbles flowing into a propeller, and to provide a ship including the air bubble removal device for the air lubrication.SOLUTION: An air bubble removal device is used in air lubrication in which air bubbles are jetted around a hull 1 to reduce friction resistance and includes: a propeller 10 provided at a stern of the hull; and air bubble concentration means 20 which causes the air bubbles to concentrate on a blade root part 11 of the propeller 10, which is provided at the front side of the propeller 10, and flows the air bubbles to the rear side.SELECTED DRAWING: Figure 2
