Embodiment Construction

[0051] Hereinafter, a ship according to an embodiment of the present invention will be described with reference to the drawings. The ship of this embodiment is as follows Figure 1~Figure 5 The bow shape shown is a displacement type ship 1 .

[0052] And, for the ship 1, if figure 2 As shown, the following area is set as the first area R1, and the front and rear direction of the area with respect to the ship 1 is a position away from the forward vertical line F.P. to the rear by 0.5% of the length Lpp between the vertical lines (Square Station) S.S.9.95 ) Sx1 and the area Xr between the position (equal line S.S.9.80) Sx2 which is 2% of the length Lpp away from the bow perpendicular F.P. to the rear, and the vertical direction of the ship 1 is the full load waterline WL and the exposure Zone Zr between decks 13.

[0053] and, if figure 2 as well as Figure 4 As shown, when a horizontal line that is 50% higher than the reference height Hs from the full-load waterline WL i...

Abstract

The following area is set as the first area (R1), which is the position (Sx1) and The area between the position (Sx2) away from the forward perpendicular (F.P.) of 2% of the length between perpendiculars (Lpp) to the rear and between the full load waterline (WL) and the exposed deck in the upper and lower direction of the ship (1) (13) In this case, in any one of the bow frame lines (Xi), the length of the specified inclined line part is 2% or more of the molded breadth of the ship for each side, and the said The bow frame line represents the shape of the hull surface in the first region (R1) in a section perpendicular to the fore-and-aft direction of the ship (1), and the specific inclined line part is the tangent line (Lx) of the bow frame line (Xi) and The angle of inclination (α) formed by the vertical direction (Lz) is 65 degrees or more from the upper side. Thereby, the flow of water at the bow portion provided with the flared bow is efficiently flowed rearward, the increase in wave-making resistance and the increase in resistance in waves are reduced, and a wide exposed deck is provided.

Description

technical field [0001] The present invention relates to a ship which can make the flow of water at the bow portion provided with a flared bow efficiently flow backward, can reduce the increase in wave-making resistance and the increase in resistance in waves, and can have a wide width. The bow shape of the exposed deck. Background technique [0002] In a displacement type ship, the shape near the front end of the bow, ie, the bow shape, is required to have a small wave-making resistance and a small increase in resistance due to waves in order to reduce the energy required for propulsion of the ship. [0003] If the shape of the bow is large, the water flowing into the bow is easily blocked when the ship moves forward, and the water surface rises due to the dynamic pressure, so large water surface waves are generated, and the wave-making resistance increases. In addition, in a wave, the incident wave is remarkably reflected forward, causing a large increase in resistance. ...
