Problems solved by technology

[0003] Usually, the ship design is often optimized only for the speed under NCR (commonly used output power), so it often has better resistance performance in the high-speed stage, but for a wider range of speed, especially in the low-speed stage, it is necessary to It is not easy to satisfy each speed with good resistance performance

Embodiment Construction

[0014] The present invention is based on the following reference coordinate system when describing dimensions.

[0015] In the X direction, along the length of the ship, it is divided into 20 intervals according to the length of the vertical lines, that is, 20 stations, numbered sequentially from the stern to the bow, the stern perpendicular is 0 station, and the bow perpendicular is 20 stations. If the length between lines is LPP, the length of each station leader is: LPP / 20. In places where the line shape changes rapidly at the bow and stern, add 0.5 or even 0.25 stations. If the range exceeds 20 stations, increase in order, then the distance of 20.5 stations The formula for calculating the length of the stern perpendicular is: LPP+0.5*(LPP / 20).

[0016] Y direction: along the width of the ship, with the midline as the zero point and the starboard side as positive, the hull is symmetrical left and right.

[0017] Z direction: along the draft direction, take the bottom of th...

Abstract

A ship, comprising: a hull and a bulbous bow located below the bow of the hull, the distance between the highest point of the upper part of the bulbous bow and the baseline is between 11.95m and 12.45m, and at the 20th station of the hull, the bulbous bow The distance from the bottom of the bow to the baseline is between 750mm and 1250mm; at the 6m waterline height of the 20th station of the hull, the distance from the outer edge of the bulbous bow to the center line is between 3100mm and 3600mm; at the 20.5th station of the hull, the bulbous bow The distance from the bottom of the nose bow to the baseline is between 4550mm and 5050mm, and at the 10m waterline height of the 20.5th station of the hull, the distance from the outer edge of the bulbous bow to the center line is between 1350mm and 1850mm. The ship changes the flow field and pressure distribution around the hull by changing the bulbous bow, so that the ship can have lower effective power at various speeds, thereby achieving the purpose of saving fuel.

Description

technical field [0001] The invention relates to the field of ship design, in particular to the bulbous bow structure of the bow of the ship. Background technique [0002] The draft of a ship refers to the depth to which the ship is submerged in water, which varies according to the design of the ship. The size of the draft depends not only on the weight of the ship and everything on board such as cargo, ballast, fuel and spare parts, but also on the density of the water in which the ship is standing. The draft of a ship can be determined by reading the water gauges marked on the bow and stern of the ship. The draft of a ship is the design draft and structural draft. The design draft of a ship refers to the corresponding draft when the ship is fully loaded in the design state. The structural draft of a ship refers to the maximum draft that the hull structure can bear. Usually, the structural draft is higher than the design draft. High, to ensure that even if the ship is heav...
