This is the groundbreaking research, paid for by the US government and published more than fifty years ago that lead to numerous developments. The existence of these movies, images, reports keeps open the hydro sport field and prevents anyone from claiming ownership and attempting to establish a monopoly. The pilot seated in the chair is connected to hoses, has a center of gravity clearly below the thrust nozzles, and is most certainly mobile in relation to the base unit, tank or compressor.
-
a body unit having a center of gravity, wherein the body unit includes a thrust assembly having at least two thrust nozzles located above the center of gravity, the thrust nozzles being pivotally coupled to the body unit;
-
a delivery conduit in fluid communication with the thrust assembly; and
-
a base unit in fluid communication with the delivery conduit, the base unit capable of delivering pressurized fluid to the delivery conduit, wherein during operation the body unit is independently movable with respect to the base unit and capable of flight.
and for good measure:
-
a platform having a bottom surface, and a top surface on which a passenger can be positioned;
-
a thrust unit adapted to be supplied with a pressurized fluid, and including at least one nozzle engaging the bottom surface of the platform and oriented to provide thrust in a direction away from the position of a passenger on the top surface; and
-
a means for collecting and distributing pressurized fluid to the nozzle, the means for collecting and distributing pressurized fluid being configured to connect a supply channel to the propulsion device;
-
wherein the means for collecting and distributing pressurized fluid comprises a base to which said supply channel is connectable, said means for collecting and distributing pressurized fluid being attached to the platform in a manner that enables the base and a connected supply channel to move relative to the platform.
