Description

Oppfinnelsen vedrører et anlegg for holding av mennsker svevende ved hjelp av en oppadrettet luftstrøm, det vil si et sveverom hvor mennesker kan holdes svevende, enten for ren forlystelse eller for treningsformål, eksempelvis for fritt fall-trening av fallskjermhoppere. The invention relates to a facility for holding people floating by means of an upward air flow, i.e. a hovering room where people can be kept floating, either for pure amusement or for training purposes, for example for free fall training of parachutists.

Hensikten med oppfinnelsen er således å tilveiebringe et sveverom. Sveverommet skal være enkelt, sikkert og økonomisk i bruk. Særlig gjelder at sveverommet skal være av en type hvor luftblåseutstyret og tilhørende kraftbehov er så beskjedent som mulig, muliggjort ved konstruktive tiltak med hensyn til utforming og plassering av luftblåseutstyret i forhold til sveverommet. The purpose of the invention is thus to provide a floating room. The hovercraft must be easy, safe and economical to use. In particular, the hover space must be of a type where the air blowing equipment and associated power requirements are as modest as possible, made possible by constructive measures with regard to the design and placement of the air blowing equipment in relation to the hover space.

Spesielt tas det sikte på å tilveiebringe et sveverom hvorIn particular, the aim is to provide a hovering space where

en luftblåsevifte er innkapslet og omgitt av et ringformet luftløp for derved fordelaktig å utnytte viftens luftstrøm inne i kapslingen direkte og også å tilveiebringe en indusert sugestrøm i luftpassasjen rundt kapslingen. Oppfinnelsen kan eksempelvis realiseres i form av en bygning med et rom eller et kammer hvor det tilveiebringes en oppadgående luftstrøm for derved å kunne holde mennesker svevende. Et slikt sveverom utformes og anordnes for enkel, sikker og økonomisk drift, an air blower fan is enclosed and surrounded by an annular air flow in order to thereby advantageously utilize the fan's airflow inside the enclosure directly and also to provide an induced suction current in the air passage around the enclosure. The invention can, for example, be realized in the form of a building with a room or a chamber where an upward flow of air is provided in order to be able to keep people floating. Such a hover room is designed and arranged for simple, safe and economical operation,

og særlig oppnås dette ved at det tilveiebringes en luftvifte som er kapslet og er anordnet for å tilveiebringe en indusert sugestrøm i en ringformet luftpassasje rundt viften.under påvirkning av den rettede viftestrøm inne i kapslingen. Det anordnes en toroidal luftpassasje for luftstrømming i lukket krets i serie gjennom luftpassasjen og svevekammeret. Mellom svevekammeret og den toroidale luftpassasje anbringes det en toroidal kjernedel, og det anordnes også et tilskuergalleri og adgangsmuligheter til svevekammeret. and in particular this is achieved by providing an air fan which is encapsulated and is arranged to provide an induced suction flow in an annular air passage around the fan under the influence of the directed fan flow inside the enclosure. A toroidal air passage is arranged for air flow in a closed circuit in series through the air passage and the levitation chamber. A toroidal core part is placed between the levitation chamber and the toroidal air passage, and a spectator gallery and access possibilities to the levitation chamber are also arranged.

Oppfinnelsen er definert i patentkravene og det vises derfor spesielt til disse. The invention is defined in the patent claims and special reference is therefore made to these.

I det etterfølgende skal det gis en beskrivelse av oppfinnelsen i form av et utførelseseksempel som er vist på tegningene, hvor fig. 1 viser et snitt gjennom et sveverom ifølge oppfinnelsen, In what follows, a description of the invention will be given in the form of an embodiment shown in the drawings, where fig. 1 shows a section through a hovering chamber according to the invention,

Det viste sveverom er anordnet i en bygning 1 som i dette tilfelle har sylindrisk form. Bygningen 1 har en sylindrisk yttervegg 2 som strekker seg koaksialt med en sylindrisk inner-vegg 3. Ytterveggen 2 og innerveggen 3 kan ha andre geometriske former og eksempelvis kan en åttekantform være aktuell. Oppfinnelsen skal således ikke være begrenset til sirkelsylindriske utforminger. Ytterveggen 2 er utformet iett med et fundament 4 og et tak 5, og er i dette tilfelle forutsatt utført i betong. 1 Bygningen 1 er utformet med et toroidalt kammer hvori det er montert en kjerne 6 som har toroidal form. Den toroidale kjerne 6 innbefatter en indre sylindrisk vegg 6a og en ytre sylindrisk vegg 9, men som nevnt kan også andre former benyttes. Den indre vegg 6a i kjernen 6 er innvendig belagt med et støtabsor-'berende belegg eller f6ring som danner en indre vegg 3. Den toroidale kjerne 6 bæres av flere søyler 7. Disse søyler er strømlinjeformet i radialretningen for derved å gi en strøm-linjeformet luftstrøm mellom dem. Innerveggen 3 omgir et svevekammer 8 og er åpen i bunn og tak slik at det dannes en ' nedrj^innløjDs^nj^ bygningen 1 danner_en_tor-oida-1—^l-u-f-ef-pa-ss-as4e—som—s trekk er~seg mellom utløpsenden 3b og innløpsenden 3a og går mellom ytterveggen 9 til kjernen 6 og ytterveggen 2 i bygningen 1. The hovering room shown is arranged in a building 1, which in this case has a cylindrical shape. The building 1 has a cylindrical outer wall 2 which extends coaxially with a cylindrical inner wall 3. The outer wall 2 and the inner wall 3 may have other geometric shapes and, for example, an octagonal shape may be relevant. The invention shall therefore not be limited to circular-cylindrical designs. The outer wall 2 is designed as one with a foundation 4 and a roof 5, and in this case is assumed to be made of concrete. 1 The building 1 is designed with a toroidal chamber in which is mounted a core 6 which has a toroidal shape. The toroidal core 6 includes an inner cylindrical wall 6a and an outer cylindrical wall 9, but as mentioned, other shapes can also be used. The inner wall 6a of the core 6 is internally coated with a shock-absorbing coating or liner which forms an inner wall 3. The toroidal core 6 is supported by several columns 7. These columns are streamlined in the radial direction to thereby provide a streamlined airflow between them. The inner wall 3 surrounds a floating chamber 8 and is open at the bottom and top so that a ' nedrj^innløjDs^nj^ the building 1 forms_a_tor-oida-1—^l-u-f-ef-pa-ss-as4e—which—s feature is~se~se between the outlet end 3b and the inlet end 3a and goes between the outer wall 9 of the core 6 and the outer wall 2 in building 1.

Den toroidale luftpassasje muliggjør således en luftstrømThe toroidal air passage thus enables an air flow

i lukket krets i serie med en oppadgående luftstrøm i svevekammeret . in a closed circuit in series with an upward air flow in the levitation chamber.

For å tilveiebringe en egnet jeyrL_ elLer^sJb.r.ømlin4Æformet—l-u-f-t-== strøm, er fundamentet 4 og taket 5 forsynt med respektive innadrettede aksiale fremspring 10 og 11. Det innadrettede eller nedadrettede aksiale fremspring i taket benyttes for montering av lyskastere 12 og annet mulig utstyr, eksempelvis ikke viste luftmålere. Det innoverrettede eller oppoverrettede aksiale fremspring 10 i gulvet bærer en luftvifte 13. Viften 13 er en propell som er montert koaksialt med svevekammeret 8 under dettes bunn og drives av en motor 14 via en girkasse 15. Propellen 13 er omgitt av en sylindrisk kapsling 16, men man In order to provide a suitable jeyrL_ elLer^sJb.r.ømlin4Æformet—l-u-f-t-== current, the foundation 4 and the roof 5 are provided with respective inward-directed axial projections 10 and 11. The inward-directed or downward-directed axial projection in the ceiling is used for mounting spotlights 12 and other possible equipment, for example air meters not shown. The inwardly directed or upwardly directed axial projection 10 in the floor carries an air fan 13. The fan 13 is a propeller which is mounted coaxially with the levitation chamber 8 below its bottom and is driven by a motor 14 via a gearbox 15. The propeller 13 is surrounded by a cylindrical casing 16, but man

er ikke bundet til denne kapslingsformen. Kapslingen bæres av flere radielle stag 30 mellom innerveggen 6a og kapslingen 16. Kapslingen 16 har en diameter som er mindre enn diameteren til innerveggen 3, slik at det mellom kapslingen og innerveggen dannes en ringformet luftpassasje 32. Propellen 13 tilveiebringe!en sugevirkning i luftpassasjen 32, og dette gir en ekstra oppadrettet luftstrøm eller sugéluftstrøm i tillegg til den oppadrettede' luftstrøm som går igjennom kapslingen 16. Propellen 13 kan derfor gjøres relativt liten, og tilsvarende kreves det derfor en mindre motor 14 enn dersom samme luftstrøm skulle produseres direkte ved hjelp av en større propell. Kapslingen 16 virker også til å redusere støy fra propellen 13 og fra den tilveiebragte luftstrøm. is not bound to this form of enclosure. The casing is supported by several radial struts 30 between the inner wall 6a and the casing 16. The casing 16 has a diameter which is smaller than the diameter of the inner wall 3, so that an annular air passage 32 is formed between the casing and the inner wall. The propeller 13 provides a suction effect in the air passage 32 . a larger propeller. The enclosure 16 also acts to reduce noise from the propeller 13 and from the provided air flow.

I kapslingen 16, under svevekammeret, er det montert et gitter over propellen 13. Gitteret 17 har et i hovedsaken V-formet tverrsnitt. Da gitteret 17 skrår mot propellens 13 senter vil gitteret avbøye luftstrømmen fra propellen 13 i retning inn-over. På gitteret 17 er det anordnet et konisk legeme 34 like over propellen 13, i propellens rotasjonsakse. Denne koniske del 3 4 gir jevn luftstrømning og hindrer turbulens som ellers ville oppstå på grunn av dø-rom like over sentrum av propellen 13. In the enclosure 16, below the hover chamber, a grid is mounted above the propeller 13. The grid 17 has a mainly V-shaped cross-section. As the grid 17 is inclined towards the center of the propeller 13, the grid will deflect the air flow from the propeller 13 inwardly upwards. A conical body 34 is arranged on the grid 17 just above the propeller 13, in the axis of rotation of the propeller. This conical part 3 4 provides uniform air flow and prevents turbulence that would otherwise occur due to dead space just above the center of the propeller 13.

En start- og landingsflate 25 ligger over den innkapslede propell og innbefatter en gitterflate 18 av et hvilket som helst egnet materiale, eksempelvis i form av et nett. Her kan per-sonene stå, samtidig som den oppadrettede luftstrøm kan gå igjennom nettet. Start- og landingsflaten 25 innbefatter også en lufttett, periferisk gangbro 19 hvor personer kan stå uten å påvirkes av luftstrømmen. Man kan så hoppe ut og inn mot sentrum av kammeret og bringes til sveving under påvirkning av luftstrømmen, slik det er vist i fig. 1. A take-off and landing surface 25 lies above the enclosed propeller and includes a grid surface 18 of any suitable material, for example in the form of a net. Here, people can stand, while the upward airflow can pass through the mesh. The take-off and landing surface 25 also includes an airtight, circumferential walkway 19 where people can stand without being affected by the air flow. One can then jump out and in towards the center of the chamber and be brought to levitation under the influence of the air flow, as shown in fig. 1.

For å hindre oppståelsen av turbulens og forstyrrende luft-strømmer ved kanten 19a til gangbroen 19 kan det i en alternativ utførelse, som er vist i fig. 8 og 9, anordnes en deflektor 40. Deflektoren 40 er fortrinnsvis fremstilt av et deformerbart materiale, eksempelvis cannvas. En stang 42 er festet til!veggen 6a over stagene 30. Deflektoren 40 er ringformet og har en ytterkant 40a og en innerkant 40b. Ytterkanten 40a er festet til den ringformede stang 42, fortrinnsvis ved at den er viklet rundt den og så sydd fast. Innerkanten 40b er en fri kant. In order to prevent the occurrence of turbulence and disturbing air currents at the edge 19a of the footbridge 19, in an alternative embodiment, which is shown in fig. 8 and 9, a deflector 40 is arranged. The deflector 40 is preferably made of a deformable material, for example canvas. A rod 42 is attached to the wall 6a above the rods 30. The deflector 40 is ring-shaped and has an outer edge 40a and an inner edge 40b. The outer edge 40a is attached to the annular rod 42, preferably by being wrapped around it and then sewn. The inner edge 40b is a free edge.

Når luft strømmer opp gjennom luftpassasjen 32 vil deflektoren 40 presses oppover i retning av pilen A og vil innta den stilling som er vist med strekpunkterte linjer i fig. 8. Innerkanten 40b til deflektoren 40 vil strekke seg opp til littjinnenfor gangbroen 19. Den skråvegg som dannes av deflektoren 40 vil hindre turbulens ved gangbroen 19 og muliggjøre en jevn og glatt luftstrøm forbi gangbroen. Når propellen 13 står stille vil deflektoren 40 innta den stilling som er vist i fig. 8 med fullt opptrukne linjer. When air flows up through the air passage 32, the deflector 40 will be pushed upwards in the direction of the arrow A and will assume the position shown by dashed lines in fig. 8. The inner edge 40b of the deflector 40 will extend up to the inside of the footbridge 19. The sloping wall formed by the deflector 40 will prevent turbulence at the footbridge 19 and enable a smooth and smooth flow of air past the footbridge. When the propeller 13 is stationary, the deflector 40 will assume the position shown in fig. 8 with solid lines.

Det er av vesentlig betydning at luftstrømmen i kammeret 8 får minimal turbulens og at man også holder friksjonen på et minimum. Disse faktorer bidrar nemlig til støynivået og til varmedan-nelse, og begge deler er uønsket. De foran beskrevne trekk er beregnet til å gi et system hvor støyen er redusert til et minimum og hvor varmedannelsen er redusert. It is of essential importance that the air flow in the chamber 8 receives minimal turbulence and that friction is also kept to a minimum. These factors contribute to the noise level and to heat generation, and both are undesirable. The features described above are intended to provide a system where noise is reduced to a minimum and where heat generation is reduced.
