FRICTIONAL RESISTANCE REDUCING DEVICE, SHIP WITH SAME, AND METHOD FOR REDUCING FRICTIONAL RESISTANCE OF SHIP

摘要

A device for reducing frictional resistance includes: a chamber (20) which is provided to a draft part of a hull and in which a plurality of blowing holes (22) blowing out air into the water of the outside of the hull from different positions to each other in a height direction of the hull are formed; a supply pipe (12) supplying the air to an internal space (Si) of the chamber (20); and a distributor (30) provided to each of the plurality of blowing holes (22), and guiding a part of the air, which was supplied inside the chamber (20) from the supply pipe (12), to each of the blowing holes (22). The plurality of distributors (30) has a flow-amount adjuster (32) adjusting a flow amount of the air guided to the blowing hole (32) corresponding to each of the plurality of distributors (30) so that the flow amount of the air blown out from the plurality of blowing holes (32) is equalized in each of the blowing holes (32).
