The shuttle-shaped double-tail-fin linear ship comprises a double-tail-fin linear stern, propellers are arranged at the tail ends of double tail fins of the double-tail-fin linear stern, tail fin contour lines, prone to generating vortexes, in front of the propellers obliquely rise forwards to form a slim shuttle cone rod body, and the original double tail fins form the shuttle-shaped double tail fins; the fusiform double-tail fin is divided into a tail section, a middle section and a front section which are smoothly connected; the width of the middle section of the fusiform twin-tail fin is 1.2-1.5 times of the width of the outer contour of the cross section of the center line of the output shaft of the gearbox, the height of the middle section of the fusiform twin-tail fin is 1.2-1.5 times of the height of the outer contour of the cross section of the center line of the gearbox, and the length of the middle section of the fusiform twin-tail fin is 1.2-1.5 times of the total length of the length of the gearbox, the length of the elastic coupler and the length of the main machine. According to the method, the line type of an existing double-tail-fin ship is optimized, the front ends of the tail fins are optimized into the fusiform streamline shape of a shuttle for ancient weaving, the ship navigation resistance is reduced, the ship rapidity is improved, and energy saving of the ship can be achieved easily.

    一种梭形双尾鳍型线船型及梭形双尾鳍设计方法,包括双尾鳍线型船尾,双尾鳍线型船尾的双尾鳍末端设有螺旋桨,螺旋桨前易产生漩涡的尾鳍轮廓线向前斜升,形成了一个纤瘦的梭锥杆体,原双尾鳍形成了梭形双尾鳍;梭形双尾鳍分为光顺连接的尾段、中段和前段;梭形双尾鳍中段的宽度等于齿轮箱输出轴中心线横剖面的外轮廓宽度的1.2~1.5倍,梭形双尾鳍中段的高度等于齿轮箱中心线处横剖面外轮廓高度的1.2~1.5倍高度,梭形双尾鳍中段的长度等于齿轮箱长度+弹性联轴器长度+主机长度的总长1.2~1.5倍。本发明对现有的双尾鳍船舶线型进行了优化,将尾鳍前端优化成古时织布用梭的梭形流线形状,降低了船舶航行阻力,提高船舶快速性,有利于实现船舶节能。
