摘 要:利用循环水槽中的垂直型平面运动机构(VPMM)对无桨和带桨全附体潜艇模型完成拘束模型试验,分析目的拟合出潜艇操纵性无因次线性水动力系数。对比可知:带桨模型的水动力系数Z'_w、M'_w和舵角系数Y'_(δr)、M'_(δs)、Z'_(δs)较无桨模型分别减小17.33%、36.33%、16.10%、30.51%、24.25%,而舵角系数N'δr较无桨时增加16.45%,其余水动力系数的变化基本维持在10%以内。由此表明螺旋桨的存在及其运行对潜艇操纵性水动力系数具有一定的影响。In this study,we performed a constraint model test,in which w e applied a vertical planar motion m e c h a-nism (VPMM ) to a submarine model with and without a propeller in a circulation tunnel. W e then analyzed and fitted the non-dimensional linear hydrodynamic coefficients. In our comparison, w e found that the hydrodynamic coefficientsY'δr、M'δs、Z'δs and the hydrodynamic coefficients of the rudder angle,N'δr of the submarine model with a propeller were decreased by 17.33%,36.33%, 16.10%,30.51%,and 24.25% , respectively. However,the rudder angle hydrodynamic coefficientN'δr increased by 16.45% compared with that of the submarine model without a propel-ler, and the other changes in the hydrodynamic coefficients were generally within the 10% range. These results show that the propeller and its rotation do influence the hydrodynamic coefficients of submarine maneuverability.
