摘要
本文对潜艇前置导叶的增效降噪机理和在宏观系列模型试验中显示出的效果进行了研究分析。结果表明潜艇前置导叶可调整螺旋桨的入流场 ,获得更好的增效降噪效果 ,具有良好的应用前景。
The effects of guide vane on submarine powering performance and propeller noise were analyzed on the basis of experimental data. The interaction between the guide vane and the propeller through fluid flow were explored according to PIV flow field results. The effect of guide vane on the propeller inflow and outflow were studied. From the analysis, it is concluded that submarine guide vane can provide pre-swirl inflow for the propeller and improve inflow uniform, so that it can increase the efficiency and reduce propeller noise.
