| Abstract: | In this paper, a propulsion pump that isthe main drive system of a ducted propulsor was analyzedroundly; it was indicated that the load noise, inverseflow noise and cavitation noise were the main noisesources, and the causes generating noise on ducted prop-ulor were discussed. Besides that, the proposal for futureresearch directions on noise reduction were presented inthis paper. In order to reduce the noise brought by duct-ed propulsor, it was indicated that some investigationsshould be carried out such as the investigation on struc-ture rationality, investigation on resisting cavitaion per-formance, and investigation on noise absorption materialetc. |
