The ship wake flow energy-saving appendage comprises a spindle-shaped main body, and the spindle-shaped main body comprises a main body drainage section located on the front section, a main body flow removal section located on the rear section and a main body upper layer structure located on the upper portion of the main body flow removal section; the main drainage section is installed at the tail end of the ship bottom, the main drainage section is located behind a ship stern transom plate, the front end face of the main upper-layer structure is tightly attached and fixedly connected with the ship stern transom plate, and the lower end face of the main upper-layer structure is tightly attached and fixedly connected with the main drainage section; the width of the horizontal section outline of the main drainage section is gradually increased from front to back, and the middle longitudinal section outline of the lower end face is configured by adopting an integrally declined spline curve; the width of the horizontal section outline of the main body flow removal section is gradually reduced from front to back, and the lower edge molded line of the middle longitudinal section outline of the lower end face is configured by adopting a spline curve which is integrally declined and then is integrally lifted from front to back. A good drag reduction effect can be achieved under the medium-low cruising working condition and the high-speed working condition, and rapidity and cruising ability of the ship are improved.

    本发明涉及一种船舶尾流节能附体,包括纺锤形主体,纺锤形主体包括位于前段的主体引流段、位于后段的主体去流段、位于主体去流段上部的主体上层结构;主体引流段安装于船底尾端,主体去流段位于船体艉封板后方,主体上层结构前端面与船体艉封板紧密贴合并固定连接,下端面与主体去流段紧密贴合并固定连接;主体引流段的水平剖面轮廓由前至后宽度逐渐增加,下端面的中纵剖面轮廓采用整体下倾的样条曲线来构型;主体去流段的水平剖面轮廓由前至后宽度逐渐变小,下端面的中纵剖面轮廓下边缘型线由前至后采用先整体下倾的样条曲线后整体抬升的样条曲线来构型。本发明在中低巡航工况和高速工况均可实现较好的减阻效果,提高了船舶的快速性与续航能力。
