Abstract: 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.

Abstract: 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.

Abstract: The invention relates to a fluid outlet interface for a personal watercraft, so that the latter can collect and divert a very small portion of the fluid pressurized by said vehicle and thus create a sufficient Venturi effect to drive the emptying of the bilge of said vehicle. The invention also relates to a personal watercraft, or more generally any floating device delivering a pressurized fluid, comprising such an interface.

Abstract: The invention relates to a Motorized Water Vehicle (MWV) adapted so as to operate as a fluid-compression station in addition to the primary transport function thereof. Such an MWV can thus supply compressed fluid to a third device. In a preferred and non-exhaustive manner, such an MWV can supply a passenger propulsion device allowing the latter to move through the air or through a fluid. The invention thus preferably relates to a propulsion system in which a remote station is a motorized water vehicle adapted such as to engage with a propulsion device.

Abstract: To improve the maneuverability and stability of a jet-pack, the thrust of the nozzles is varied relative to one another, through a suitable valve arrangement. The ability to reduce the pressure on one side of the jet-pack enables much more flexible turns to be accomplished, and requires much less effort on the part of the passenger. Actuators, such as piston-cylinder arrangements, control the positioning of the nozzles and thereby assist the passenger in the piloting of the jet-pack. To further increase maneuverability, additional nozzles can be incorporated into the jet-pack to control the forward and backward tilt of the device, to more easily accomplish hovering, forward movement and backward movement.
