Description

1 - Levitation installation allowing floating

of humans in the air.

  The subject of the present invention is an installation allowing human levitation by means of an upwardly directed air flow and, in particular, a levitation installation in which the floating of humans in the air has for its object either the sole pleasure of users and

  spectators, or training, such as that of the pra-

  free fall parachute tick.

  A general object of the present invention is to provide

  a levitation installation of the aforementioned type.

  Another general object of the present invention is to provide an aforementioned levitation installation which

  be simple, sare and economical in its operation.

  A more specific object of the present invention lies in the fact of making an installation for levitating the

  aforementioned type in which the air blast and the

  associated with it are kept to a minimum by an appropriate construction and arrangement of the propeller

  which produces the breath of air in the levitation chamber.

  Another more specific object of the present invention consists in providing a levitation installation of the aforementioned type in which a propulsion propeller

  the air is provided with an environment and is located inside

  laughter of an annular air passage so as to advantageously use the direct air flow produced by the propeller inside its surround, and also a suction flow induced in the air passage located around said surround . The present invention defines an installation as it is in the form of an enclosure having a chamber in which a directed air flow is produced

  upward to levitate humans.

  This installation, which can be called "levitation-

  rium ", is made and arranged to be simple, safe 2 - and economical in its operation, in particular because it comprises an air propeller which

  is provided with an enclosure and which is arranged so as to pro-

  lasts a suction flow induced in an annular air passage

  re which surrounds it, under the action of the direct flux produced by

  the propeller inside the entourage, this thanks to a step-

  sage of toroidal air arranged to form a closed circuit for the laminar air flow which passes through it and which passes, in series, the levitation chamber, a toroidal core being interposed between the levitation chamber and the toroldal air passage and realizing a gallery for spectators and an access to the levitation chamber The above-mentioned aims, like others as well, as well as the advantages of the present invention will be better understood

  with reference to the following detailed description of a

  preferred embodiment of the invention which is illustrated, by way of example, in the accompanying drawings, in which

  Fig 1 is a sectional elevation of a levitationa-

  rium for the floating of human beings in the air.

  Figs 2, 3, 4 and 5 are sections along the lines

  2-2, 3-3, 4-4 and 5-5, respectively.

  Fig 6 is an enlarged view of the central part of Fig 2, and Fig 7 is a section along line 7-7 of Fig 2 which illustrates in particular an air blower system. The levitationarium shown comprises an enclosure 1 constituted, in this case, by a shaped building

  general cylindrical This enclosure 1 comprises a wall la-

  cylindrical outer wall 2 coaxial with an inner wall

  cylindrical wall 3 The external cylindrical wall came in one piece with a base 4 and with a roof 5, all in concrete The building 1 has a toroidal chamber

  cylindrical in which is mounted a core 6 of to-

also roidal.

  The toroidal core has internal cylindrical walls

  inner and outer The inner cylindrical wall 3

  of the toroidal core is covered internally with a coating

  3 - shock absorbing The toroidal core 6 is supported by a plurality of pillars 7 which are radially tapered, to allow a laminar air flow to flow between them The inner cylindrical wall 3 limits a cylindrical levitation chamber 8 open at its base and at its top to form a lower inlet and a summit outlet The space located inside the enclosure 1 forms a toroidal air passage extending between the summit outlet and the inlet of base of the cylindrical chamber of

  levitation 8 and which passes between the external cylindrical wall

  9 of the core 6 and the outer cylindrical wall 2 of the

  building 1 This toroidal air passage thus creates a circuit

  cooked closed for an air flow directed vertically in the

levitation chamber.

  In order to produce an appropriate laminar air flow, the base 4 and the ceiling 5 each have an axial projection

  directed inward, 10 and 11, respectively

  Take advantage of these internal axial projections to fix light projectors 12 and other useful accessories such as air flow measuring devices, not shown On the basic internal axial projection 10

  is mounted an air blower constituted by a propeller 13.

  The latter is mounted coaxially to the levita-

  tion 8, at the base of it, and is driven by a mo-

  tor 14 through a gear boot 15 The

  lice 13 is surrounded by a cylindrical surround 16 which is smaller in diameter than the inner cylindrical wall 3 and defines with it an annular air passage The propeller

  13 produces air suction in the above air passage

  mentioned and, thus, an additional air flow adding to its own direct air flow Thus, the relatively small propeller 13 requires a substantially smaller motor 14

  than that which would be necessary if the same air flow from-

  should be entirely produced only directly.

  A grid 17 is mounted in the levitation chamber,

above the propeller 13.

  A take-off and landing base is located above

  above the propeller and includes a grid 18, made in all -4-

  suitable material, supporting users standing by-

  end while allowing the flow of air directed upwards to pass through it The take-off and landing base comprises an impermeable peripheral sidewalk 19 on which people can stand substantially sheltered from the air flow directed towards the high and from which they

  can dive toward the center of the room to be

  lifted by the air flow and placed in a floating state,

as shown in fig 1.

  The core 6 forms superimposed annular galleries 20 on which spectators can be authorized to

  access to observe users through windows 21 meters

  swam in the wall 3 Sidewalks 22 and passages 23 are provided to give access to the interior chamber of

  levitation through the toroidal surrounding part of the building

  ment 1 The apexes and base of the internal parts of the building such as the core 6 and the passages 23 are curved and tapered to produce maximum air flow efficiency

  in accordance with known designs of aerodynamics.
