Problems solved by technology

However, unlike existing manufacturing methods such as the integral molding method using a metal model such as the automobile drag reducing device, or the heating and pressurizing molding method such as the aircraft manufacturing technology, the ship drag reduction made of composite materials is manufactured by integral molding. installation is very difficult
[0007] In addition, composite materials are relatively weak to welding heat, so it is difficult to manufacture drag reduction devices through welding operations or install drag reduction devices on the hull
In addition, the drag reducing device is manufactured by the normal temperature pressure molding method similar to the manufacturing of the blades of the wind power generator, which is not practical enough in terms of the cost compared with the effect.

Embodiment Construction

[0064] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0065] figure 1 It is a use state diagram which shows the state in which the drag reducing device of the ship of the embodiment of this invention is applied to a ship.

[0066] refer to figure 1 , the drag reducing device 100 of the embodiment of the present invention can be installed on the bow side deck of the ship 10 . For example, the ship 10 may include an ultra-large container ship, but is not limited thereto. When the ship 10 is sailing, the drag reducing device 100 can block or reduce the resistance caused by air, water (for example, ship deck waves), and wind to the ship body, thereby reducing the fuel consumption of the ship 10 . In addition, the drag reducing device 100 can also prevent the maximum speed of the ship 10 from decreasing or improve the efficiency of the maneuverability of the ship 10 .

Abstract

Disclosed are a resistance reducing apparatus for a ship, a unit for manufacturing the same and a manufacturing method thereof. The resistance reducing apparatus for a ship according to an embodiment of the present invention includes: frame parts arranged on the deck of the ship's bow; and a plurality of panels covering spaces between the frame parts so as to reduce the resistance exerted by fluid on the shipped cargoes.

Description

technical field [0001] The invention relates to a ship drag reducing device, a manufacturing unit and a manufacturing method for manufacturing the drag reducing device. Background technique [0002] Usually, when a ship is sailing, it is subjected to the resistance of water and waves to the hull, as well as the resistance of air and wind to the hull. In fact, air resistance is an important reason for the high fuel consumption of the ship, the decrease of the maximum speed of the ship, and the decrease of the maneuverability of the ship. In particular, the shape of the main hull and the cargo loaded on the water part of ships such as ultra-large container ships and cargo transport ships is similar to a cuboid, such as ships with a high exposed height on the water and a large wind pressure area. The resistance caused by the collision with the water surface caused by the green water rushing to the bow of the ship is very large, so the bow part is subject to great resistance. ...
