PURPOSE:To enhance the steering efficiency by providing a duct at the outlet from a nozzle of a water jet propulsive machine in such a way as capable of swinging the head to the left and right, furnishing a main jet at the tail of this duct, furnishing aux. jets in the left and right...
The invention discloses a novel high-efficiency low-noise low-vibration pump water-jet propeller. A rotor part is composed of impellers in two levels, and the impellers in two levels rotate counter. The first-level impeller has the characteristics of being high in side inclination, forward ...
In terms of the propulsion mode, AUV can be divided into propeller propulsion AUV and bionic propulsion AUV. Bionic propulsion modes include the fish-like propulsion, jellyfish propulsion [27], [28], and bio-inspired jet propulsion [29]. Considering the propeller propulsion AUVs are more widely...

In detail, two jets were equipped at the head and tail cabin to control the steering, and the middle jet thruster was applied for vertical movement. Further, the third generation was a hybrid-driven underwater glider, which was equipped with a device powered by a propeller and a jet pump....
An effective method for comparing the turbulence intensity from LDA measurements and CFD predictions within a ship propeller jet. Ocean. Eng. 2012, 52, 105–124. [Google Scholar] [CrossRef] Chen, Y.; Wang, L.; Hua, H.X. Longitudinal vibration of marine propeller-shafting system induced by...
However, the complex mechanical structure of the vector water jet propulsion reduces the system’s reliability [9]. In comparison, the vector propulsion system based on the propeller not only has the priorities of flexible assemble mode and high propulsion efficiency, but also maintains high ...
