This arrangement provides alternative steering control to the use of waterjet bucket deflection or rudder angle at high ship speed. Compared with conventional technique of improving dynamic control and course of high-speed vessels, a number of advantages are achieved with side-mounted interceptors, such as: − Higher maintained vessel speed
Jet Boat Steering: Directional Thrust – JetBoatPilot
Jet Boats use directional thrust to steer both at slow speeds and high speeds as well as to create reverse control. This directional thrust is achieved by bending the water flow exiting the jet pump in either the left or right direction by way of a deflector nozzle and by diverting the water exiting the jet nozzle underneath the boat by way of ...
High pressure waterjet propulsion with thrust vector control system ...
2018年5月15日 · To improve the maneuverability of underwater vehicles, a high-pressure waterjet propulsion system combined with a Thrust Vector Control System (TVCS) was presented, which controlled the sailing trajectory through adjusting the waterjet deflection angle and thrust vector instead of rudders and sterns.
Water-Jet propulsion control systems - waterjet propulsion system
The helm wheel hydraulic pump is directly connected to the waterjet hydraulic steering actuator through hoses, but the oil feed is taken from the waterjet integrated gearbox. In multiple installations it is possible to switch the oil feed from one waterjet to another by means of a dedicated steering feed panel.
US6224434B1 - Pump jet with axial directional flow control …
A pump jet in which the axial flow of water through the device is controlled by bleeding exhaust gas into the pump jet water stream, thereby producing a thrust loss. The addition of gas...
Waterjet University - Pumps - WARDJet
The directional control valves control the flow of oil into and out of each side of the hydraulic cylinder. At each end of the hydraulic cylinder is an end plate that is used to connect the hydraulic cylinder to the high pressure cylinder.
Variant speed directional control mechanism for water-jet …
The invention easily attaches to water jet powered craft dramatically improving the steering capability during off-plane maneuvering. Its unique design allows adjustable torsion loading, rotates on one or both sides and allows precise tuning for multiple crafts from personal watercraft to large water jet powered crafts.
US20120132119A1 - Variant speed directional control mechanism for water ...
The invention relates to an auxiliary appendage(s) to improve off plane steering response and maneuverability of water jet powered crafts. The invention utilizes the pump's water flow and...
US3611972A - Ship water jet directional control and braking …
Water jets are discharged from the front of the ship by a pump installed in a Y-shaped duct into which the water flows longitudinally, centrally of the ship and from which the flow discharges...
Do Jet Boats Have Reverse? Understanding Jet Boat Maneuvering and Control
The key component of a jet boat’s propulsion system is the water jet pump. Water gets sucked into the intake, passes through an impeller that increases pressure, and is then directed out of the nozzle at high speed. The operator can change the direction of …
