摘　　要：本文提出拖式吊舱螺旋桨 (螺旋桨位于吊舱首部 )定常水动力性能的势流理论计算方法。螺旋桨采用升力面理论涡格法、吊舱采用面元法分析计算 ,二者的相互干扰通过叠代计算来处理。考虑吊舱的影响 ,修改了尾涡模型。应用本方法 ,计算了拖式吊舱螺旋桨的定常性能 ,并与空泡水筒试验结果进行了比较 。A numerical method based on the potential flow theory is proposed in this paper for predicting the steady performance of tractor-type podded propellers. The propeller blades are calculated by a vortex lattice method, while the pod including its strut by a boundary element method for non-lifting bodies. Hydrodynamic interactions between the propeller and the pod are treated via iterative calculations. To account for the influence of the pod on the trailing vortex wake of the propeller blades, an existing trailing vortex wake model is modified. With the present method, the steady performances of podded propellers are calculated, and the results agree well with experimental data obtained in a cavitation tunnel.
