Embodiment Construction

[0022] like figure 1 and figure 2 A new type of bow is shown, the bow 1 has a design waterline 2 and a baseline 3; the longitudinal length of the part of the bow 1 below the baseline 3 is a, where a > 0.2 meters; the bow 1 The maximum vertical distance of the part below the baseline 3 is b, where b>0; further, a<0.5*L, where a is the longitudinal length of the part of the bow 1 below the baseline 3, and L is the design waterline 2; further, b<2*d, wherein b is the maximum vertical distance of the bow 1 below the baseline 3, and d is the distance from the baseline 3 to the design waterline 2; further Specifically, the bow 1 includes an upper deck 4, and the length of the upper deck 4 is less than the length of the design waterline 2; further, the longitudinal distance between the front end of the upper deck 4 and the front end of the design water line 2 is c, 0 <c<0.4*L, L is the longitudinal length of the design waterline 2; further, the front end of the design waterline 2 ...

Abstract

The invention discloses a novel ship bow which is provided with a designed waterline and a base line. The longitudinal length of the portion, located below the base line, of the ship bow is a and a is larger than 0.2 m. The maximum perpendicular distance of the portion, located below the base line, of the ship bow is b and b is larger than 0. The ship bow comprises an upper deck. The length of the upper deck is smaller than that of the designed waterline. The volume of displacement on the portion of the ship bow is increased, so that the volume of displacement is evenly distributed in the length direction of a ship, the whole designed waterline is made to be thin, and wave-making resistance is reduced in navigation.

Description

technical field [0001] The invention belongs to the field of ship design, in particular to a novel bow. Background technique [0002] In recent years, with global warming, severe weather has increased significantly, energy conservation and emission reduction and the promotion of green environmental protection have become issues of close concern to governments and people in various countries. In the shipping industry, the demand for energy conservation and emission reduction is also the same. Existing high-speed ships The resistance to overcome during navigation is relatively large, which increases the energy consumption of the ship. [0003] It is well known that the shape of the ship's bow directly affects the resistance of the ship when it is sailing; among them, the shape of the head of the design waterline has a greater impact on the wave-making resistance. Should be lean. Generally, for a low-speed ship, the proportion of wave-making resistance to the total resistance...
