摘要：

Pump-jet propulsion is a kind of propeller with excellent performance. Because of its high working efficiency and good anti-cavitation performance, it has been widely concerned and studied by scholars at home and abroad. This paper takes the self-designed pump-jet propulsion as the research object. The hydrodynamic and noise experiment of pump-jet propulsion was carried out based on the towing tank and the cavitation tunnel. It analyzes the mechanical characteristics and noise performance of pump-jet propulsion, compares and verifies the test results with CFD calculation results. The results show that the calculated values of hydrodynamic force and noise of pump-jet propulsion are in good agreement with the experimental test results, which further verifies the reliability of the calculation strategy in this paper. At the same time, it provides theoretical basis and data support for the performance forecast and optimization design of the subsequent pump-jet propulsion.
