摘　　要：采用涡环升力面方法分析螺旋桨水动力性能.螺旋桨尾涡面由双曲四边形面元进行离散,每个面元上布置线性偶极子分布,尾涡面卷曲形状由运动学边界条件来确定.在诱导速度计算中引入了非奇异光滑参数.尾涡面的数值模拟结果是合理的,方法是稳定的.与经验尾涡模型相比,螺旋桨敞水性能的预报精度有所提高,计算结果与试验结果吻合较好.The Vortex Lattice Lifting Surface Method is adopted to analyze the hydrodynamic performance of the propeller. Trailing vortex surface behind each blades is discreted by a number of small hyperboloidal quadrilateral panels with the linear doublet distribution on each panel. The geometry of trailing vortex sheet roll-up is determined by the kinematics condition. The desingularization smoothing parameter is introduced in calculating the induced velocity on trailing vortex surface. The numerical simulation result is reasonable and the method is robust. The open-water characteristic is more accurate than the trailing vortex model by experience, the calculation results are in satisfactory agreement with experimental data.
