| 摘 要： | 建立了计算导管螺旋桨在均流中的定常水动力性能的数值方法，螺肇桨用涡格法，导管用面元法分别计算，两者的相互影响则通过迭代计算加以考虑，为了减少计量量，螺旋桨对导管的诱导速率周向平均值，从而使导管周围的非定常流动简化为定常对称流动，应用本法地ＪＤ简易导管桨系列进行了计算，数值结果试验数据吻合良好。

| Abstract: | A numerical method is presented for predicting the steady performance of ducted propellers operating in a uniform flow. The propeller is calculated with a vortex lattice method and the duct with a surface panel method, while the hydrodynamic interaction between them is treated in an iterative manner. To reduce the amount of computation, the velocities induced by the propeller are circumfe rentially averaged, so that the physically periodical flow around the duct is simplified as a steady, axisymmetrical flow. |
