jetboat draws the water from under the boat through an intake and into a pump-jet inside the boat, before expelling it through a nozzle at the stern. The...

or more different principles of jet propulsion. A water jet, or pump-jet, is a marine propulsion system that uses a jet of water. The mechanical arrangement...

steam propels the torpedo in a closed Rankine cycle, supplying power to a pump-jet. This propulsion system offers the very important deep-water performance...

of vacuum pump, which produces vacuum by means of the Venturi effect. In an ejector, a working fluid (liquid or gaseous) flows through a jet nozzle into...

Water jet may refer to: A jet of water under pressure, like in an ornamental fountain or drain cleaner Pump-jet, a marine propulsion mechanism for jetskis...
