A personal flying water jet board system includes a jet board with a water jet propulsion system. A water intake system mounted on either side of a boat includes an intake member submerged in the water and connected to a hose which is connected to jet nozzles of the jet board. The water injected into the jet nozzles propels the jet board and user above the water. A water intake system mounted on the boat is fluidically connected to the hose and directs water into the jet nozzles. Water-conducting support pipes have intake members with an intake end oriented towards the forward end of the boat to receive water as the boat moves forward and a discharge end. The intake end of the intake member is shaped to increases the water pressure as the water flows into the discharge end thereof and into the water-conducting support pipes.

A propulsion device, including a platform arranged to seat a passenger; a thrust assembly coupled to the platform, the thrust assembly including at least two nozzles configured to discharge a pressurized fluid therefrom that are movable with respect to the platform; a plurality of actuators, wherein each actuator is coupled to one of the at least two nozzles, wherein each actuator is configured to adjust an angular orientation of its respective nozzle with respect to the platform; a first sensor coupled to the platform to measure at least one of a pitch and roll of the platform; and a controller in communication with the first sensor and the plurality of actuators, wherein the controller is configured to adjust an operation of the actuators based at least in part on information from the first sensor to modify an angular orientation of the at least two nozzles.

A propulsion device includes a platform with a pair of elbowed tubular thrust nozzles respectively located on opposite sides of the platform. An input end of each nozzle is mounted to the platform and rotatable about a transverse axis that is normal to a longitudinal axis of the platform, and is connected to a source of pressurized fluid. A pair of actuators are respectively connected to the tubular nozzles to rotate the nozzles around the transverse axis and thereby change the orientation of output ends of the nozzles relative to the platform. A processor controls the position of the platform by activating the actuators to rotate the nozzles, and thereby change the direction of thrust emitted by the pressurized fluid at the output ends of the nozzles.

A hydro flight jet board comprising of a flexible Y manifold capable of third axis movement, a horizontal rocker arm, pivot hinge and a vertical hinge arm and a thrust unit.

The invention relates to a propulsion device comprising a platform that is arranged so as to accommodate a passenger and cooperates with a thrust unit comprising a main nozzle, advantageously oriented from the bow to the stern of the device, and two secondary nozzles that are lateral and are positioned essentially at the bow of the propulsion device. The secondary nozzles are mounted so as to be mobile about a transverse axis so as to be moved by actuators controlled by a processing unit that implements a method for controlling the secondary nozzles, thus providing automatic control assistance to the passenger.

The invention relates to a device for propelling a passenger, comprising a body arranged to receive said passenger and cooperating with a fuel-fed thrust unit.

More specifically, the thrust unit comprises at least one thrust sub-unit, each advantageously comprising at least two thrusters and secondary course-correction and/attitude-correction thrusters.

A water-propelled or water-powered unmanned aerial vehicle including a base configured to carry a payload, and at least one nozzle attached thereto. The at least one nozzle is configured to selectively receive pressurized fluid from a source located remotely from the vehicle. The vehicle includes a control system configured to alter or otherwise selectively dictate the flow of fluid through the at least one nozzle and/or the orientation of the at least one nozzle with respect to the base in response to a received control signal for providing controlled unmanned vehicle flight.

A propulsion device includes a platform which provides support for a passenger. The platform comprises an upper surface and a lower surface, and cooperates with means for collecting and distributing a pressurized fluid to a primary nozzle expelling the fluid from a fluid outlet in a fluid expulsion direction. The means are supplied with pressurized fluid by a fluid supply conduit. The primary nozzle is oriented substantially from the bow to the stern of the platform. The fluid expulsion direction of the primary nozzle is located in a median plane of the platform. The fluid expulsion direction of the primary nozzle describes defines an angle comprised between 10 and +45 with a longitudinal axis of the platform contained in the median plane. The means for collecting and distributing a fluid cooperate with the platform by an embedding link.
