摘　　要：为了解决水下航行体新型高性能泵喷推进器工程应用的技术瓶颈,本文采用理论分析与数值试验相结合方式,探索了泵喷总体选型的理论依据和三维外形的设计方法。根据"航行体-泵喷-主机"三者能量相互平衡的原理,推导了泵喷总体参数选取步骤。采用叶片三元设计理论与CFD相互迭代方法,完成泵喷叶型设计。本文以MK48鱼雷为例,演示了泵喷选型和设计过程,计算结果表明该泵喷效率超过90%,相同功率条件下推进航速与国外公开数据一致,验证了该选型和设计方法的准确性。In order to solve the problems in the engineering application of high-performance pumpjet thruster of underwater vehicle,this paper attempted to do some search about the global parameters selection and three-dimension design of pumpjet thruster with theoretical analysis and numerical experimentation. At first,pumpjet＇ s parameters were systematical selected based on the energy equilibrium principle of the ＂ underwater vehicle-pumpjet-main engine＂ system. According to the design parameters selected,the pumpjet blades were designed with the iteration of three-dimensional inverse design procedure and CFD method,the profile of duct was airfoil structure. In the end,the MK48 torpedo was used as an object to demonstrate the type selection and design of pumpjet thruster,the computation results indicated that the designed model had a high efficiency of more than 90%,and the speed of torpedo reached the international level with the same shaft power,so the method for type selection and three dimensional design of pumpjet thruster is verified.
