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.

A tower may support a horizontal track and a vertical climbing wall therebelow. A trolley, movable along the track, may be selectively driven toward and away from the tower by belay lines, line and capstan, positive drive, or some combination. Belay lines reeved over pulleys on the trolley may be taken up and paid out independently from the trolley, while fixed or moving. A rider may climb, be lifted, or both to near the intersection of the tower and track, from there to fall or jump into a controllable trajectory such as swinging or simulating a parachute landing. Swinging may be rapidly attenuated almost entirely by “bumps,” lifting a rider to remove momentum and kinetic energy as a rider moves toward a pivot point overhead. Control may be simplified based on sensing and using timing past bottom dead center (BDC).

A wind tunnel for stable sustained human flight for research or recreation, including a tunnel including first and second portions having first and second central axes, respectively, and a fan to create an air flow in the test section. The second portion is a test section. The first and second central axes are arranged at a first angle with respect to each other. The second central axis is at a second angle of 5°-85° with respect to a horizontal plane. A safety system for an inclined wind tunnel for stable sustained human flight is provided, including an inclined test section of the wind tunnel that is arranged at an angle of 5°-85° with respect to a horizontal plane, a fan to create an air flow in the test section directed from an upstream end towards a downstream end thereof, and a delimiting arrangement arranged at the test section for preventing a person using the test section from leaving it.

Provided is a virtual experience device for aviation leisure sports, the device including: a main frame configured to form a vertical pillar and having an accommodation space in a region of an inside of the main frame; a bottom frame connected to the main frame and configured to form a bottom surface of the virtual experience device for aviation leisure sports; an upper frame extending from the main frame in a horizontal direction and having an accommodation space in a region of an inside of the upper frame and at least one through hole formed in a bottom surface of the upper frame; side frames installed at both sides of the upper frame and configured to support a load of the upper frame; and at least one roller provided in the accommodation space of the upper frame and configured to change a progression direction of a traction wire connected to a harness that will be put on by a user for a leisure sports aircraft virtual experience, wherein a motor portion for adjusting a usage length of the traction wire is provided at a top end of the main frame.
