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.

Abstract: The invention relates to a propulsion device (10) comprising a body (11) arranged for receiving a passenger (1) and engaging with a thrust unit (12a, 12b, 13a, 13b) supplied with a pressurized fluid from a compression station. The arrangement of such a device offers great freedom of movement through the air or under the surface of a fluid. The invention also relates to a propulsion system in which the compression station can be remote in the form of a motorized marine vehicle.

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: The invention relates to a propulsion device (10) comprising a body (11) arranged for receiving a passenger (1) and engaging with a thrust unit (12a, 12b, 13a, 13b) supplied with a pressurised fluid from a compression station. The arrangement of such a device offers great freedom of movement through the air or under the surface of a fluid. The invention also relates to a propulsion system in which the compression station can be remote in the form of a motorised marine vehicle.
