ABSTRACT:
For artificially producing air flow for the purpose of causing people to float in the air stream so produced, a device in the form of a supporting skeleton is provided, which is adapted to be dismantled and transported and designed for set-up on a flat base, said device having a wind duct with a unit for accelerating the air and an associated air flow straightener arranged therein. The floating space is limited by nets for protecting the people floating therein. One net is arranged above the flow straightener and another net is disposed above the device. The net serving as the top limitation is arched upwardly by the flow of air produced, for which purpose it has a central insert which is impermeable or nearly impermeable to air. For spectators, a stand is arranged extending around the supporting skeleton, serving at the same time as an access way for people entering the floating space.
