A vertical wind tunnel for indoor skydiving having at least one recirculating airflow plenum. The airflow plenum includes a first vertical member housing a flight chamber, a top horizontal member, a second vertical member, and a bottom horizontal member. The bottom horizontal member has a first section and a second section. A corner section connects the second section of the bottom horizontal member with the first vertical member. The second section of the bottom horizontal member contracts the airflow travelling through the bottom horizontal member between the first section and its exit to the corner section. The corner section further contracts the airflow exiting the second section of the bottom horizontal member towards the first vertical member.

The vertical wind tunnel further comprises an upholstery ring (8) arranged above the flexible net ring (6) for further absorption of impacts. The present invention increases a safety of its users effectively absorbing impacts of falling flyers.

A free fall simulator comprising: a wind tunnel system; a flight chamber connected to the wind tunnel system such that the wind tunnel system and the flight chamber allow for a continuous flow of circulating air, and a cooling system for cooling of the air circulating in the wind tunnel system, wherein the cooling system comprises: an air inlet sucking in a part of the air circulating in the wind tunnel system; at least one heat exchanger comprising a coolant: and at least one air outlet adapted such that the cooled air leaves the cooling system through the at least one air outlet. The cooling system further comprises: a closed pressure chamber comprising a cooling area, wherein pressure in said cooling area is higher than atmospheric pressure, and at least one auxiliary fan configured to maintain pressure within the cooling area of the pressure chamber higher than the atmospheric pressure, wherein the at least one heat exchanger is located inside of the closed pressure chamber so that the cooling of the circulating air takes place in the cooling area.

Invention relates to an open vertical wind tunnels for simulating a free fall sky diving. An open vertical wind tunnel comprising: a frame structure (1), a power unit (2) and a fan assembly (3); a flow straightening assembly (4) comprising a vertical cylindrical housing (42) to be mounted above and coaxially with the propeller (3); a central cone (43) disposed within and coaxially with the vertical cylindrical housing (42); a plurality of radially oriented vertically disposed guide vanes (44), where each guide vane (44) is configured to straighten an air flow and absorb created noise; a flight platform (5); and sound attenuating panels (6) arranged around the open vertical wind tunnel.

A cooling system for a wind tunnel is disclosed. The heat exchanger of the present disclosure is formed as a turning vane in an airflow duct of a re-circulating wind tunnels. The individual vanes are formed from extruded aluminum with coolant fluid channels running continually down the length of the vane. One or more channels can be used, depending on the application of vane and the cooling capacity needed. The exterior of the vanes are formed in an airfoil shape to efficiently turn the air flow the desired amount in a manner well known in the art. The turning vanes are connected to a fluid supply with single piece connectors that removably attach to the turning vanes. In the depicted embodiment the connectors are attached with screws. In the depicted embodiment the connectors are formed as a single piece in a two-piece injection mold.

An interactive modular sensor system for an indoor skydiving wind tunnel. The system comprises a plurality of nodes arranged around the flight chamber of the wind tunnel. The nodes have at least one sensor and at least one light source. The sensors are configured to detect user movement within the flight chamber. The light sources are configured to change appearance between at least two indicator states. A network connects the plurality of nodes. A program coordinates the activity of the nodes, whereby each of the nodes may be individually controlled. The program may include various modes with different user objectives and rules. Users are directed to perform or not perform actions by the light source indicator states of each node, and the sensor monitors for the occurrence of such actions. Information from multiple systems may be compiled in an inter-tunnel system. Other aspects of the system are also described.
