Unmanned Underwater Vehicle (UUV), which could be used for ocean exploration and development, developed rapidly in recent years. In order to make UUV quieter to be competent for rigorous working conditions, a new propulsion with lower underwater noise must be designed. A new high-skew ducted propeller, which had the advantages of both ducted propeller and high-skew propeller, had been designed for UUV to obtain adequate thrust and lower underwater noise. CFD simulation of the high-skew ducted propeller showed that the thrust was enough for UUV working underwater and the hydrodynamic efficiency was very close to that of conventional ducted propeller. The strength of high-skew ducted propeller had been checked by FEM method, and the maximum stress would appear on the trailing side of blade on 0.5R, where the blade was unsubstantial. Underwater noise had also been measured, which proved that the high-skew ducted propeller had lower noise than that of conventional ducted propellers. As a quiet propulsion, the high-skew ducted propeller could be used on UUV or ship who want to be quiet underwater.
