Pump-jet - Wikipedia
A pump-jet, hydrojet, or water jet is a marine system that produces a jet of water for propulsion. The mechanical arrangement may be a ducted propeller ( axial-flow pump ), a centrifugal pump , or a mixed flow pump which is a combination of both centrifugal and axial designs.

Waterjets: When to Use, Pros and Cons - DMS Marine Consultant
Waterjets work by pumping a LOT of water through a closed duct. The acceleration of this water creates a forward thrust for propulsion. Figure 2‑1 shows a typical arrangement for a waterjet. Suck the water in at the bottom, the impeller adds power, and …
Performance Assessment of the Waterjet Propulsion System …
Waterjet propulsion system has three main components: Inlet, Pump and Nozzle. Figure 1 shows typical waterjet arrangement while Figure 2 demonstrates the idealized profile of the jet system. Sea water enters the system with the velocity and leaves it with a different velocity .
Waterjet propulsion - Wärtsilä
A typical waterjet system includes a flush-mounted inlet channel guiding the water to the rotating pump impeller, a stationary guide vane package, an outlet nozzle and a steering/reversing mechanism. The basic operating principle of waterjet propulsion is similar to that of a screw propeller system.
A Breakthrough in Waterjet Propulsion Systems - ResearchGate
2008年1月1日 · Waterjet propulsion on an unmanned surface vehicle is a propulsion system with the working principle of taking water from the bottom of the hull into the turbine to be blown back out and...
Waterjets for any ship size - Wärtsilä
How does waterjet propulsion work? A waterjet generates propulsive thrust by sucking water into a pump unit through an intake/inlet located on the bottom of the vessel, then forcing the water out through the impeller, propelling the vessel forward.
