吹出し装置。[Scope of Claim for Utility Model Registration] Air is blown into the water from air blowing pipes facing the surface of the outer skin, which are provided at multiple locations on the outer skin of the submerged part of the hull, using an air pump installed inside the hull. In the air blowing device, the air blowing device is configured to blow out water, thereby reducing frictional resistance between the hull and the water, wherein the air blowing pipe is 4 times relative to the outer panel.
The air blowing pipe is attached to the outer plate so as to form an angle of 5 degrees or less and an acute angle with respect to the direction of the water flow, and an opening of the pipe to the surface of the outer plate An air blowing device, characterized in that the tube expands into an ellipse substantially in the direction of the water flow.
