How does a vertical wind tunnel work?

How does a vertical wind tunnel work?

Open-circuit wind tunnels use a continuous stream of new air, drawn in at the bottom and expelled at the top. Powerful fans direct the air upwards, producing a jet upon which people can float. These tunnels can be made in portable form and used outdoors too for a more natural skydiving experience.

What is a vertical tunnel called?

In civil engineering a shaft is an underground vertical or inclined passageway. Shafts are often entered through a manhole and closed by a manhole cover. They are constructed for a number of reasons including: For the construction of a tunnel. For ventilation of a tunnel or underground structure.

How much is a vertical wind tunnel?

How much does it cost to build a Vertical Wind Tunnel Facility? – A high quality portable vertical wind tunnel will cost you anywhere from $300,000 – $750,000 US Dollars. This type of tunnel can accommodate skydivers as well as tourists, and can be relocated easily to locations with high volume traffic.

What are the different types of wind tunnel?

Wind tunnels are classified as low-speed or high-speed; they are further classified as subsonic (80 percent of the speed of sound), transonic (about the speed of sound), supersonic (up to 6 times the speed of sound), hypersonic (6 to 12 times the speed of sound), and hypervelocity (over 12 times the speed of sound).

When was iFLY founded?

1998
iFLY makes the dream of flight a reality by giving customers the ability to fly in a safe and reliable environment. This experiential entertainment company, that created modern indoor skydiving, started in 1998 by CEO Alan Metni who gave up his lucrative legal career to follow his dreams.

What kind of fans does iFLY use?

To simulate free-fall conditions in a vertical wind tunnel (VWT), iFly, a company with numerous international indoor skydiving locations, uses a total of four 450 hp fans to draw air through a flight chamber and return the air down the sides of Return Air Towers (RATs).

What is shaft tunnel?

Definition of shaft tunnel : a narrow watertight compartment through which the propeller shaft of a ship passes from the after engine-room bulkhead to the stern tube.

What is a pilot tunnel?

Term. Definition. Pilot tunnel. A small tunnel excavated over the entire length or over part of a larger tunnel, to explore ground conditions and/or to assist in final excavation. May also be referred to as “pilot drift “.

How many iFLY are there in the world?

Overall, we have opened more than 80 locations worldwide in countries including the United States, Canada, Brazil, France, New Zealand, Australia, Great Britain, China and Singapore. Along the way, we’ve done so much more than put up buildings.

How much is an I fly franchise?

The initial investment for an iFly franchise ranges from $2 million to $10 million.

What are the 2 main types of wind tunnel?

Wind Tunnel Test There are basically two types of wind tunnel test which are static stability and the pressure test. With these two tests, you can determine the aerodynamic characteristics of the aircraft.

What are the 5 parts of a wind tunnel?

Finally, you should know the five basic parts of the wind tunnel. From front to back, they are: The Settling Chamber, the Contraction Cone, the Test Section, the Diffuser, and the Drive Section. (see Figure E).

What is the difference between indoor and outdoor vertical wind tunnel?

The airflow of an indoor vertical wind tunnel is usually smoother and more controlled than that of an outdoor unit. Indoor tunnels are more temperature-controllable, so they are operated year-round even in cold climates. Various propellers and fan types can be used as the mechanism to move air through a vertical wind tunnel.

What is vertical wind tunnel skydiving?

A vertical wind tunnel is frequently called ‘indoor skydiving’ due to the popularity of vertical wind tunnels among skydivers, who report that the sensation is extremely similar to skydiving. The human body ‘floats’ in midair in a vertical wind tunnel, replicating the physics of ‘body flight’ or ‘ bodyflight ‘ experienced during freefall.

What is the history of vertical wind tunnel technology?

A milestone in vertical wind tunnel history was ‘Wind Machine’ at the closing ceremonies of the 2006 Torino Winter Olympics. This was a custom-built unit by Aerodium (Latvia/Canada) for the closing ceremony. Many people had never seen a vertical wind tunnel before, and were fascinated by the flying humans with no wires.

What are recirculating wind tunnels and how do they work?

Recirculating wind tunnels are usually built in climates that are too cold for non-recirculating wind tunnels. The airflow of an indoor vertical wind tunnel is usually smoother and more controlled than that of an outdoor unit. Indoor tunnels are more temperature-controllable, so they are operated year-round even in cold climates.
