Cool the air inside the tunnel
to ensure a comfortable flight

8. TECHNOLOGY: HOW IT WORKS?
HOW IT WORKS?
Four axial fans driven by electric motors with total power of 1,600 kilowatts create a strong
vertical airflow with a maximum speed of more than 300 kilometres per hour (190 miles per
hour). Even a 4VFS team flying head-down can comfortably acquire new skills in this kind of
airflow.
Our tunnels utilize ZeroTurbulence® (patent-pending) technology, which eliminates even
minor turbulence in the flight chamber, allowing all skydivers, even the most inexperienced,
to feel the true sensations of skydiving.
The optimum design of the flight chamber, with its perfectly round shape, 4.5-metre diame-
ter, and two levels of glass, makes it possible to fully enjoy dynamic flights at all speeds.
The innovative air conditioning system makes flying even more comfortable when it is hot
outside, without annoying moisture or cold spots.

9. TECHNOLOGY: HOW IT WORKS?
FLIGHT CHAMBER
The flight chamber is 4.5 metres (14.76 feet) in diameter, with a total height of 19.4 metres.
It is perfectly round in shape, allowing flyers to use the space fully while bodyflying.
The curved, high-strength glass ensures the safety of flyers and makes it easy for spectators
to observe the action. The glass in the flight chamber is two levels high, with a glass floor
separating the levels.
Access to the antechamber is provided through pressure doors. The doors can be opened or
closed at any time, as this does not affect the wind stream.

10. TECHNOLOGY: HOW IT WORKS?
TECHNOLOGY
Four axial fans, driven by electric motors 1, push the air through left and right loops. The
power of each motor is 400–450 kilowatts.
The six sets of turning vanes 4 efficiently direct the air through the bends, while coolant in-
side the vanes smoothly removes heat from the air.
The left and right airflows are combined in the airjet 5 in the lower centre of the tunnel, creat-
ing a single airflow that is directed into the flight chamber 2 located in the vertical part of the
tunnel.
The air exchangers in the upper horizontal diffusers 3 provide fresh air, and can also be used
to cool the air.

14. TECHNOLOGY: AXIAL FANS
AXIAL FANS
The airflow is created by highly efficient axial fans, each 3.5 metres in diameter, manufac-
tured by EVG (www.evg-group.de) – one of the leading manufacturers of industrial ventilation
systems. The heart of the axial fan is the 400-450 kilowatt electric motor made by Siemens.
Each axial fan is supplied with:
• an individual frequency convertor
• carbon-fibre blades (lighter and more reliable than aluminium blades)
• vibration dampers
• a set of sensors and diagnostics controllers: vibration, temperature, oil, dynamic and static
pressure (pitot tubes)
The axial fans are installed during construction work by EVG engineers. Installation usually
takes approximately two weeks.

BEHIND THE SCENE

20. BUSINESS: BUILDING
BUILDING YOUR OWN WIND TUNNEL BUSINESS
Step 1 | Deciding to set up a wind tunnel business.
Step 2 | Selecting the right country and city.
As a rule of thumb, the local population should be more than 2.5–3 million people within a
50-kilometre radius. A smaller population may result in a lack of clients during the initial pe-
riod after opening. It is, however, possible to attract additional clients using good marketing
practices, though results will depend on many factors.
| How we can help:
We can help to prepare feasibility studies and business plans, and to evaluate various ways of
developing the business, depending on different pricing policies.
Duration depends on the information available about the specific location, city and country.
Step 3 | Choosing the right location
The main criteria are easy access for all clients and convenient accessibility to transportation.
Duration depends on availability of land.
Step 4 | Selecting the right equipment suplier
To choose the right equipment supplier, you should pay attention to the following points:
• Equipment quality. Ask other owners of the same equipment what they think about it.
Are they pleased with it? What problems did they encounter? How much time and money
have they spent on maintenance?
• Noise. Do noise levels comply with local regulations? Will you and your staff be comfort-
able with the level of noise in public areas?
• Vibration level. Inefficient tunnel design can cause high vibration levels in public areas,
which are uncomfortable and make the whole structure less reliable. Visit some facilities
with the equipment you have chosen and pay attention to the vibration levels in public
areas when the tunnel is operating at its highest speed.
• Contract terms:
• Some suppliers require a franchise fee to be paid on a regular basis – is this the case with your chosen
supplier?
• Check delivery terms: who pays for the delivery and insurance, and who assumes the delivery risks?
• Who handles customs clearance? Who pays customs fees? If these are not included in the equipment cost,
then they should be carefully estimated.
• Who pays for equipment installation? How much installation work is covered by the contract?
• Software quality.Pay attention to software quality. Does it provide all the functionality you
need? Ask how it handles hardware failures. Is it only for tunnel control, or does it provide
full business automation?
• Equipment cost

21. BUSINESS: BUILDING
| How we can help:
Our approach is not just about selling competitive equipment ready for installation. We offer
a business model which includes all aspects of dealing with clients and makes it possible to
turn a profit at each stage, providing full control over all processes within the business.
The centralized control system includes:
• Technical aspect – control of the equipment.
• Financial aspect – all income from clients.
• CRM/marketing aspect – all information about clients and their activity.
• Management aspect – information about all staff activities and performance evaluation.
Step 5 | Designing the facility
The facility, including the concrete building and all public areas, landscaping, etc., should be
designed by a local civil engineering company familiar with all local regulations. Selecting the
right company is the responsibility of the investor.
The supplier of the wind tunnel equipment provides all necessary documentation to the engi-
neering company.
The engineering company designs all elements of the projects, including electricity, water
supply, and so on.
| How we can help:
We can help investors choose a suitable engineering company. We supply all necessary information to the
engineering company and participate in the design process to achieve the goals faster. Our engineers help to
design each part of the project. Depending on the investor’s vision for the building, we can provide a sig-
nificant amount of complete design documentation (for existing buildings), which may require only minor
modifications by the engineering company.
The cost of the design work depends on many factors, and the process may take around 3–4 months.
Step 6 | Obtaining all necessary building pemits
Regulatory bodies usually request additional information concerning the technical aspects
of wind tunnel operation. Ask the supplier if they are able to provide all necessary infor-
mation about the technical details to the authorities, especially information treated as
“know-how”.
| How we can help:
We are happy to provide all information requested by authorities about the equipment. Additional calcula-
tions and studies can be carried out on request

22. BUSINESS: BUILDING
Step 7 | Construction
Once a building permit is obtained, the investor chooses a construction company. The
company’s experience and the construction cost are usually the main factors in the deci-
sion.
| How we can help:
Tunnel Technologies can help investors choose a suitable builder and negotiate the price.
Our engineers are able to oversee construction and assist in planning and schedule opti-
mization.
Depending on the complexity of the building, construction could take from 8 to 18 months.
7.1 | Installing the equipment
Installing the wind tunnel equipment is an essential part of the construction process. Some
tunnels are designed to be installed after the concrete building is finished, while others must
be installed during construction. The latter method is always more convenient, but not all
construction companies can accommodate it.
| How we can help:
Our equipment can be installed after the concrete building is finished or during construction.
Our engineers coordinate the plans for construction and installation to optimize the schedule
and reduce the total project cost.
We also provide all the specifications for the equipment needed for installation.
Installation takes approximately three months and is carried out simultaneously with construction.
Step 8 | Commissioning the facility
After the equipment is installed, the facility is commissioned. This usually happens during the
final stages of construction and finishing. After commissioning, the tunnel can be used for
flying even if the finishing work is not complete.
The period after commissioning and before the official launch is usually used to train staff,
including:
• Instructors (10–14 people, depending on planned capacity)
• Receptionists
• Technicians (for equipment maintenance)
| How we can help:
Tunnel Technologies will train your instructors and manage their work in order to:
• Provide superior service and safety for first-time and experienced flyers
• Motivate clients to buy additional services (upselling)
• Increase client loyalty and encourage them to become regular flyers
We will also train your administrative staff to work with the tunnel control panel (reserva-
tions, CRM, taking photos/video).

23. BUSINESS: BUILDING
Step 9 | Organizing a wind tunnel business
As business processes are developed and launched, special attention should be paid to:
• Understanding marketing aspects, promoting the wind tunnel efficiently and correctly esti-
mating how effective promotional activities will be
• Understanding possible options for advertising and promotions
• Gathering and making efficient use of statistical data on the wind tunnel (who flew and
when, where did they come from, etc.)
| How we can help:
We will teach your staff about all aspects of the wind tunnel business. They will be trained to
use business automation software, which makes it possible to:
• Monitor the activities of every client
• Keep track of all reservations and associated information
• Keep track of all cash flow
• Keep track of all technical data – equipment load, condition, usage and malfunctions – and
link this data with client flow information
• Search for correlations between marketing activities, client flow and visits to the website
We are sure that your desire to run a wind tunnel, together with our knowledge and experi-
ence, will ensure that your project is a huge success!
