The invention relates to a stern end resistance reduction device, and belongs to the technical field of ship design. A stern end resistance reduction device is provided with at least one group of turbulence devices along a water flow separation line part of a stern transom plate or a part within 2000mm of the front part of the water flow separation line part. A small-size turbulence device is adopted, the size of a separation area is reduced when water flow flows and is separated near the stern transom plate, and therefore resistance is reduced to a certain degree, and design is ingenious; theconstruction cost is extremely low, and construction is very easy; and the operation cost and the maintenance cost are not needed.

    本发明涉及一种船尾端减阻装置,属于船舶设计技术领域。一种船尾端减阻装置,沿艉封板的水流分离线部位,或水流分离线部位前部2000mm以内的部位,设有至少一组扰流装置。本发明采用小尺寸的扰流装置,减小水流在艉封板附近发生流动分离时的分离区域的大小,从而达到一定程度的阻力减小,设计巧妙;建造成本极其低廉,建造非常容易;无需运行成本,无需维护成本。
