Problems solved by technology

However, such sailing conditions lead to deviations in the temperature of the air flowing into the air compressor, so there is a problem of reducing the efficiency of the air compressor
For example, ships sailing in tropical areas or sailing in hot summer have the problem of high-temperature air flowing into the compressor above normal temperature, and ships sailing in cold regions or sailing in cold winter have the problem of low-temperature air flowing into the compressor question

Embodiment Construction

[0073] Hereinafter, preferred embodiments of the present invention will be described in detail based on the attached exemplary drawings.

[0074] In the following description of the present invention, the terms referring to the constituent elements of the present invention are named in consideration of the functions of each constituent element, and therefore should not be understood as limiting the meaning of the technical constituent elements of the present invention.

[0075] Meanwhile, throughout the specification, "connection" of a certain structure to other structures means not only the case of "direct connection" of these structures, but also the case of "indirect connection" through other structures in between. In addition, in the absence of a contrary description, "comprising" a certain constituent element means that other constituent elements may also be included rather than excluding other constituent elements.

Abstract

A ship according to one embodiment of the present invention includes: a first air storage part arranged on the bow side of the hull, and including an injection port configured to be able to inject air into water; and a plurality of second air storage parts arranged in a ratio of The first air storage part is closer to the stern side and includes an injection port configured to inject air into the water, the plurality of second air storage parts are arranged at a first interval along the width direction of the hull, and the The first interval is smaller than the length of the first air storage unit in the ship width direction.

Description

technical field [0001] The present invention relates to a ship configured to improve navigation efficiency, and more particularly, to a ship configured to minimize frictional resistance between the ship and seawater by using a friction reducing device. Background technique [0002] Ships sailing at sea will encounter a lot of resistance when sailing. For example, when a ship is sailing, frictional resistance mainly occurs on the wetted surface area of ​​the hull. This frictional resistance accounts for about 80% of the total resistance in low-speed ships and about 50% of the total resistance in high-speed ships. [0003] The frictional resistance generated on the hull is due to the viscosity of water particles in contact with the hull. Therefore, if the viscosity of water is blocked by forming a layer of a substance having a lower specific gravity than water between the hull of the ship and the water, the frictional resistance as described above can be significantly reduce...
