摘要：
The low-noise optimization design of an unmanned underwater vehicle (UUV) pumpjet was developed based on 3D inverse problem design of rotating machinery. Computational fluid dynamics and computational acoustics after credibility of all methods was verified. Results showed that off-loaded tip, skew and rake of the rotor blades can decrease the interaction between the rotor and the stator, and reduce the rotor noise as well. The interaction between the rotor blades and the duct was weakened by shortening the length of the rotor blade top. Numerical results of above redesign for reducing pumpjet noise show that the stationary component noise and the total noise of the whole pumpjet are both significantly decreased. © 2019, Editorial Board of Journal of Huazhong University of Science and Technology.
