基于模型的导管螺旋桨水动力性能研究

Study on Hydrodynamic Performance of Ducted Propeller Based on Model

以某拖网渔船设计的导管螺旋桨和普通螺旋桨为研究对象,通过模型加工、敞水试验,计算并绘制其敞水性征曲线,比较分析两桨的水动力性能,得出导管螺旋桨优良的推进性能。即拖网渔船如采用导管螺旋桨作为推进器,可以达到节能的效果。

The paper adopts the ducted propeller and common propeller of a trawler as re- search subjects. The hydrodynamic performance of two kinds of propellers are compared by model processing, open water testing, calculating and drawing of open water performance line, the conclusion is obtained that the ducted propeller has a better propulsion performance, the ducted propeller should be adopted in the thruster to reach the object of energy saving.
