摘　　要：单桨、导管桨和泵喷推进器是水下航行器常用的3种典型推进器。论文在某型前置定子式泵喷推进器模型的基础上建立了2种新的模型,分别为只包含转子的单桨模型和包含转子、导管的导管桨模型。基于分离涡模拟方法,对这3种模型的水动力性能、流场进行了对比研究。结果表明,相对于单桨和导管桨,泵喷推进器的水动力性能有明显提高。此外,前置定子对转子叶片上的非定常载荷有较大的影响,改变了其幅值和频率特性,而导管对转子叶片上的非定常载荷影响较小。单桨和导管桨转子叶片上激振力的特征频率是转子的通过频率,而泵喷推进器转子叶片上激振力的特征频率是定子的通过频率。论文的结论对水下航行器的推进器选型和水动力性能研究有一定的工程指导意义。Single propeller, ducted propeller and pump jet propulsor are commonly used in underwater vehicles.In this paper, two models are established for a propulsor containing the rotor blades and a ducted propeller containing rotor and duct respectively. Based on the improved delayed detached eddy simulation method,the hydrodynamic performance and flow field of these two models together with the original pumpjet model are compared between each other. The results show that the hydrodynamic performance of the pumpjet propulsor is significantly improved compared with the single propeller and ducted propeller. In addition, the pre-swirl stator has great influence on the unsteady load on the rotor blade, while the duct only has little influence on it. The characteristic frequency of the exciting force on the single rotor blade of the single propeller and ducted propeller is the passing frequency of the rotor, while the characteristic frequency of the exciting force on the pumpjet is the passing frequency of the stator. This paper has certain engineering guiding significance for the selection of propeller types and the study of hydrodynamic performance of underwater vehicles.
