Invention refers to skydiving simulators in vertical wind tunnels, especially to recirculating vertical wind tunnels. Recirculating vertical wind tunnel is characterized in that it comprises at least three recirculating channels (5), wherein its first ends (6) are in aerodynamical communication with upper end (7) of the vertical wind tunnel (1), but the second ends (8) of the recirculating channels (5) are in aerodynamical communication with lower end (9) of the vertical wind tunnel (1) providing closed wind flow channel. Propeller (10) and drive motor (11) is arranged in the recirculating channel (5), wherein propeller (10) is positioned in the middle section of the recirculating tunnel (5). |
