Embodiment Construction

[0013] The present invention will be further described below in conjunction with drawings and embodiments.

[0014] Figure 4 In the new-type bow linear inland ship shown, a bow perpendicular line A perpendicular to the horizontal plane is provided at the bow of the ship. Such as Figure 5 As shown, in the bow longitudinal section of the ship, most of the bow contour of the ship centered on the design draft is vertically downward.

[0015] When the ship's aspect ratio (the ratio of the total length to the molded width) is 5.729, and the molded width-to-draft ratio (the length ratio of the molded width to the waterline) is 4.129, the square coefficient CB is 0.875, and the waterplane surface coefficient Cw is 0.954. The longitudinal prismatic coefficient Cp is 0.876, the vertical prismatic coefficient Cvp is 0.916, and the transverse prismatic coefficient Cxp is 0.887. Squareness coefficient CB, water plane coefficient Cw, longitudinal prismatic coefficient Cp, vertical pris...

Abstract

The invention discloses a novel bow linear inland river ship. A bow of the novel bow linear inland river ship is provided with a bow perpendicular which is perpendicular to the horizontal plane; most of a bow contour line of the novel bow linear inland river ship, with designed draft as a center, is vertically downward in a longitudinal sectional drawing of the bow of the novel bow linear inland river ship; and the block coefficient Cb is 0.875, the waterline coefficient Cw is 0.954, the longitudinal prismatic coefficient Cp is 0.876, the vertical prismatic coefficient Cvp is 0.916, and the transverse prismatic coefficient Cxp is 0.887 when the aspect ratio of the novel bow linear inland river ship is 5.729 and the molded breadth draft ratio is 4.129. The novel bow linear inland river ship has the advantages of enabling bow linear types of inland river shipping ships to be enriched and being large in boatload and good in resistance performance.

Description

technical field [0001] The invention relates to an inland waterway shipping vessel with a novel bow linear structure. Background technique [0002] Inland waterway ships mainly consist of bulbous bows (such as figure 1 shown), pointed bow (as shown figure 2 shown) and oblique bow (as shown image 3 shown) consists of three categories. Bulbous bow, also known as bulbous bow, referred to as bulbous bow, is that the front part of the bow below the design waterline is approximately spherical. The bulbous bow is a special bow that people are very familiar with, and it has been widely used by modern transport ships. Almost all ships navigating in inland rivers use the bulbous bow structure, such as oil tankers, bulk carriers, container ships, etc. ship. [0003] The main function of the bulbous bow is to reduce resistance and improve the speed of the ship. It has a more prominent impact on low-speed fat ships engaged in long-distance transportation. According to statistics, ...
