Abstract:
A thruster assembly that in addition to propulsion provides water flow to/from compartments and systems on board a vessel. In a first position, the thruster assembly provides propulsion/steering. Pivoted to a second position, operation of the thruster in a first direction draws a flow into the vessel and in a second direction draws a flow out of the vessel. The flows may be conveyed to/from compartments/systems on board the vessel via conduits in communication with a chamber having an opening through which the thruster drives the flows. The flows may be used to submerge/surface the vessel, or to provide systems cooling or serve other functions. Pivoted to a third position the thruster assembly is retracted and enclosed within the chamber to form a hydrodynamically clean exterior.

Abstract:
Watercraft that consists of a mid section with a seat and two side sections, and which has a steering mechanism, whereby the watercraft consists of a front part and a rear part that are coupled together by a hinged coupling, whereby the front part is formed by the mid section, and the side sections form part of the rear part, whereby the hinged coupling forms part of the steering mechanism, such that as a result of a rotation of the front part with respect to the rear part of the watercraft around the hinged coupling, the sailing direction of the watercraft is changed.
Abstract:
The nautical propulsion system apparatus for surface and/or underwater navigation comprises a propulsion system body (101), a unit (1) for feeding a delivery or primary flow to the propulsion system body (101); the feed unit (1) comprising an internal combustion engine (2) and a pump (3) driven by the internal combustion engine (2).
Abstract:
The invention relates to a jet propulsion device (114) for watercraft, comprising a drive housing (130) through which an admission channel (116) extends that has an inlet opening (120) disposed below the water level (118) for admission of water. Said water is enriched with energy by means of propulsion energy, thereby producing a propulsion water jet that is ejected into the surrounding water via an outlet opening (122) provided on the opposite end of the admission channel (116). Inside the admission channel (116) through which the water flows a plurality of sources supplying pressurized propulsion water are connected and propulsion water jet nozzles (128) are disposed. Said jet nozzles are substantially oriented in the direction of flow of the admission channel (116) and are disposed in the zone of the interior wall of the admission channel (116) off-set with respect to one another in the peripheral direction of the admission channel. The admission channel (116), at least in a partial area thereof, has the form of a jet nozzle (126) widening towards the outlet. The propulsion water jet nozzles (128) are disposed either upstream of or in the area of the smallest admission cross-section of the jet nozzle (126).
Abstract:
A water outlet for a jet pump in a jet-powered watercraft comprises a first end for coupling to a jet expulsion end of the jet pump in fluid-tight communication, and a second end adapted to be coupled to a hose, whereby the watercraft jet pump is converted from a propulsion pump for propelling the watercraft to a fluid pump for pumping water through the hose. In some embodiments the watercraft jet outlet is adapted to connect to a hose. In other embodiments a separate adapter coupler is adapted to couple a hose to the existing jet outlet.

Abstract:
A system for converting hydrogen into useful work comprising a combustion chamber, a source of working fluid, an accumulator, a propulsion system, and a control valve. A mixture of hydrogen and oxygen is ignited in the combustion chamber to act, directly or indirectly, on the working fluid to pressurize the working fluid. The accumulator is operatively connected to the combustion chamber such that pressurized fluid within the combustion chamber flows into the accumulator. The propulsion system converts pressurized connected between the accumulator and the propulsion system to control a flow of pressurized working fluid from the accumulator to the propulsion system
