A pump-jet works by having an intake (usually at the bottom of the hull) that allows water to pass underneath the vessel into the engines. Water enters the pump through this inlet. The pump can be of a centrifugal design for high speeds, or an axial flow pump for low to medium speeds. The water pressure inside the inlet is increased by the pump ...
The Abrasive Water Suspension Jet (AWSJ) - often called “Slurry Jet” or “Water Abrasive Suspension (WAS) jet” - is a specific type of abrasive water jet, which is used for waterjet cutting. In contrast to the abrasive water injector jet (AWIJ), the abrasive water suspension jet (AWSJ) [ 25 ] is characterised by the fact that the mixing ...
A water jet, or pump-jet, is a marine propulsion system that uses a jet of water. The mechanical arrangement may be a ducted propeller with nozzle, or a centrifugal compressor and nozzle. The pump-jet must be driven by a separate engine such as a Diesel or gas turbine. A pump jet schematic.
Beriev Be-200 filling water tanks in the Mediterranean Sea while in operation during the 2010 Mount Carmel forest fire. The Beriev Be-200 Altair (Russian: Бериев Бе-200 «Альтаир») is a jet-powered amphibious flying boat of utility type designed and built by the Beriev Aircraft Company.
Notable engine with water fuel injection: BMW 801, Daimler-Benz DB 605, Junkers Jumo 213. When used in a turbine engine, the effects are similar, except that normally preventing detonation is not the primary goal. Water is normally injected either at the compressor inlet or in the diffuser just before the combustion chambers.

At speed, jetboats can be safely operated in less than 7.5 cm (3 inches) of water. A jetboat powers through the rapids of Niagara Gorge, near Niagara Falls. One of the most significant breakthroughs, in the development of the waterjet, was to change the design so it expelled the jetstream above the water line, contrary to many people's ...
