ABSTRACT:
An improved thruster system is provided for maneuvering and/or propulsion of a marine vessel, through the use of directionally oriented water jets discharged tangentially from a helical-conical flow chamber. The thruster system includes a high capacity pump for pumping water through a hull intake to the flow chamber with a substantial helical or swirling action. The water exits the flow chamber through one or more of a plurality of tangentially oriented discharge conduits having discharge nozzles for passage of high velocity water jets through the hull, resulting in reaction forces used to maneuver or propel the vessel. Each discharge conduit includes a valve member movable between open and closed positions for respectively permitting or preventing water flow to the associated nozzle.
