Application of Direct-driven Multistage Supercharging Technology in Water Jet Propulsion Devices

In order to solve the problems of complex transmission and low power density of water jet propulsion devices, a direct-driven multistage supercharging structure suitable for such devices is designed, and the computational fluid dynamics (CFD) method is used for numerical calculation and verification analysis. The results show that the designed structure can improve the performance of water jet propulsion devices, which is of great significance to the integrated development of such devices.
