| 摘 要： | 系统研究了导缘带凹凸结节的船用舵水动力性能，通过循环水槽模型试验的方法模拟船用舵在一定来流的水中工作情况。制作导缘光滑和导缘带凹凸结节的船用舵的试验模型；针对同一个模型在循环水槽中进行三次来流速度相同的试验；记录并处理试验数据。模型试验结果表明：当其他条件相同时，在船用舵的导缘布置正弦的凹凸结节，可以提高船用舵的水动力性能，并延缓失速现象的发生。

| Abstract: | This paper systematically investigates the hydrodynamic performance of leading-edge tubercle rudder by simulation of operation condition of rudder in steady inlfow through the model test in circulating water tunnel. Firstly, it builds models of rudder with smoothing leading-edge and tubercle leading-edge. Secondly, it carries out the model tests with the same inlfow velocity three times for the same rudder in circulating tunnel. Finally, it records and processes experimental data. The model test results show that, under the same condition, rudder with sinusoidal tubercle leading-edge can improve the hydrodynamic performance of ship rudder and delay the phenomenon of stalling. |
