| 摘 要： | 基于单桨式吊舱推进器定常水动力性能的理论计算方法及试验，探讨了吊舱对螺旋桨水动力性能的影响。性能理论计算中螺旋桨采用升力面理论涡格法，吊舱采用面元法，对螺旋桨与吊舱的相互影响进行了时间平均及迭代处理。通过计算分析了吊舱对桨叶载荷分布的影响，以及吊舱引起的伴流分布特性。

| Abstract: | Based on the theoretical prediction method and experimental results for single-propeller type podded propulsors, the influences of the pod upon the propeller hydrodynamic performance were investigated. The propeller blades are calculated with a vortex lattice method, while the pod including its strut with a boundary element method for non-lifting bodies. Hydrodynamic interactions between the propeller and the pod are treated via iterative calculations. Based on the present numerical results, the influence of the pod on the radial distribution of circulation as well as the pod-induced wake characteristics were discussed. |
