An installation in the form of a building (1) has a room or chamber (8) in which an upward airflow is produced to levitate human beings and is constructed so as to be simple, safe and economical to operate, by comprising a shrouded air impeller (13) which produces an induced suction flow in an annular air passage around it, under the action of the direct flow produced by the impeller inside the shroud (16); by having a toroidal air passage which provides closed circuit streamline air flow serially through it and the levitation chamber (8); and by including a toroidal core portion (6) which is interposed between chamber and the air passage and which provides a spectator gallery (20) and access to the chamber. A grating (18) provides a take-off and landing base and has a peripheral walkway (19) on which people can stand clear of the upward air flow. <IMAGE> |
