Novel triple-hulled vessel

Abstract

The invention discloses a novel triple-hulled vessel. The novel triple-hulled vessel comprises a main hull and two side hulls located at the two sides of the main hull respectively. The main hull and the two side hulls are provided with design water lines and zero buttocks. The distance between the zero buttock of the main hull and the zero buttock of any side hull is Y, Y is larger than (BWL+bWL) / 2, BWL is the maximal width of the design water line of the main hull, and bWL is the maximal width of the design water line of each side hull. The vertical distance between the center position of the main hull in the length direction and the tail end of the main hull is X1 on the horizontal plane where the design water line of the main hull and the design water lines of the side hulls are located, the vertical distance between the center position of any side hull in the length direction and the tail end of the main hull is X2, and X2 is larger than X1. By the adoption of the novel triple-hulled vessel, arrangement of a deck at the front middle portion of the vessel is facilitated, the total resistance of the vessel is reduced, and meanwhile impact on head structures of the side hulls is reduced.

Description

technical field [0001] The invention relates to the field of ship design, in particular to a novel trimaran. Background technique [0002] High-performance ships are currently a hot spot in the research of the world's ship industry. As an important part of multihull ships, trimarans are one of the main objects of high-performance ship research. The trimaran includes the main hull in the middle and the side hulls on both sides of the main hull. The three hulls share a main deck and superstructure; the trimaran has good speed, good stability, superior overall layout and seaworthiness. Strong and other advantages. [0003] It is known that when a ship sails in a straight line at a constant speed on the water surface, the intersection of the shear wave and the scattered wave emerging from the bow forms a sharp angle. The included angle is 19°28', which is called the Kelvin angle. In addition, when the Froude number Fr>0.4 of the ship, in addition to the wave-making phenome...

AI Technical Summary

Problems solved by technology

In addition, when the Froude number Fr>0.4, in addition to the wave-making phenomenon, the ship will also have obvious splashing phenomenon

[0004] The existing trimaran has the following problems: the center position of the side hull of the trimaran is generally behind the middle of the ship, and the bow of the side hull is not only affected by the original waves at sea, but also affected by the waves and waves caused by the bow of the main hull. The additional effect of splash not only increases the total resistance of the ship, but also the structure of the bow of the side hull will be subject to greater stress
