Recirculating vertical wind tunnel skydiving simulator

DETAILED DESCRIPTION An aspect of the present invention is to provide a vertical wind tunnel amusement device having a flight chamber situated on the inlet side of a plurality of fans which are in turn connected to a plurality of expanding return air ducts, thereby maximizing efficiency while minimizing the height of the amusement device.
Another aspect of the present invention is to provide a vertical wind tunnel having a flight chamber on the inlet side of the fans for improved airflow speed and quality, at lower power consumption and higher safety for the fliers.
Another aspect of the present invention is to provide a vertical wind tunnel having a two-stage staging area adjacent and connected to the flight chamber in a way that allows people to move in between the two without stopping the airflow.
Another aspect of the present invention is to provide a vertical wind tunnel having transparent windows allowing spectators, instructors or others outside the flight chamber to see into it, including in a shopping mall venue.
Another aspect of the present invention is to provide a vertical wind tunnel having a plurality of smaller fans angled in a non-parallel alignment rather than a single, more expensive and difficult to maintain fan.
Another aspect of the present invention is to provide a vertical wind tunnel having one or more return air ducts to conserve heat, reduce energy consumption, reduce noise and allow all-weather operation.
Another aspect of the present invention is to provide a vertical wind tunnel having only one or two return ducts even though it may have a greater number of fans than return ducts.
Another aspect of the present invention is to provide a vertical wind tunnel having fans housed in low profile, diffusing casings that allow them to be mounted as closely together as possible so that more than one fan can be connected to each return air duct without the need for long transition ducts that would increase the height or width of the entire system.
Another aspect of the present invention is to provide a vertical wind tunnel having a passive air exchange system with adjustable inlet/outlet doors that mechanically ejects heated air from the system and draw in cooler ambient air in order to most efficiently control the temperature inside the wind tunnel with minimal extra work by the fans
