A pump-jet, hydrojet, water jet, or jet drive uses a ducted propeller (axial-flow pump), centrifugal pump, or mixed flow pump to create a jet of water for propulsion. These incorporate an intake for source water and a nozzle to direct its flow out, generating momentum, and in most cases, employing thrust vectoring to steer the craft.
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. The design also incorporates an intake to provide water to the pump and ...
The company develops, designs and produces high performance turbines for primarily for marine applications, boats and fire-suppression pumps. It gained fame and became noted for developing and building what may be the most powerful and fastest street-legal motorcycle in the world, the turboshaft-powered MTT Y2K Turbine Superbike.
Jet propulsion is produced by some reaction engines or animals when thrust is generated by a fast moving jet of fluid in accordance with Newton's laws of motion.It is most effective when the Reynolds number is high—that is, the object being propelled is relatively large and passing through a low-viscosity medium.
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.
Accessory Gearbox – bevel gears that extract 35 to 100 hp (26 to 75 kW) from the high-pressure spool to operate the fuel control unit, starter, oil pump, and vehicle hydraulic pump Power Turbines – the first stage of the two-stage power turbine is driven by a variable-geometry nozzle to improve efficiency

The teardrop-shaped openings along the outer edge of the turbine are the air channels used to cool the blades. Cutaway of J35 combustor dome Cutaway of J35 fuel atomizer. The engine had its starter and accessories (fuel control, fuel pump, oil pumps, hydraulic pump, RPM generator) [3] mounted in the center of the compressor inlet. This ...
