FAQ

anything
1. Does ISG sell or rent mobile units, Outdoor Facilities or Open-Flows?
No. Our company is specialized in the manufacture and sales of closed recirculating vertical wind tunnel systems (“Recirculators”).
2. How much does the construction of a wind tunnel cost?
The total investment for a wind tunnel project typically ranges between €4 and €10 million, depending on factors such as tunnel size, location, and the specific requirements for the service building.
This estimate includes:
- Purchase and installation of technical equipment
- Construction of the tunnel and service facilities
- Start-up costs such as instructor training and launch marketing
Approximately 50% of the budget goes toward the technical equipment, with the remainder allocated to construction and operational setup.
Please note: construction costs can vary significantly based on your local building regulations, infrastructure, and the desired scale, design, and finish of the facility.
Sales brochures and price lists are directly available from ISG; however, please note you will be required to sign an NDA.
3. What do I have to consider when building and operating a vertical wind tunnel?
Planning to build and operate a vertical wind tunnel, the following should be considered:
- Location and infrastructure
- Customer-Mix (entertainment, skydivers, military)
- Tunnel size (12, 13, 14 or 17 ft.)
- Financing Construction and operating permit (including construction height limitations, local noise levels)
- The building size for an ISG Vertical Wind Tunnel depends on the individual tunnel model. Following, please find the size measurements for the tunnel building (excluding service building) and the recommended construction depth:
| ISG Tunnel Model | Measures (L×W×H) in meter (m) | Recommended Construction Depth in meter (m) |
|---|---|---|
| ISG 12.800 | 6,55 × 15,88 × 27,48 | 4–8 m |
| ISG 13.500 | 6 × 14 × 20 | 4–8 m |
| ISG 14.1200 | 7,65 × 18,54 × 32,08 | 5–16 m |
| ISG 17.1800 | 9,29 × 22,50 × 38,94 | 7–18 m |
- ISG customers are free regarding the individual size and design of the interior and exterior of the service building.
- For the reference facility in Bottrop, Germany, ISG chose a compact service building of 350 sqm. The company further decided for an integrated design and embedded the tunnel in the service building, resulting in a total built-up area of only 550 sqm.
4. How long does it take to build the wind tunnel facility?
The erection time of a wind tunnel facility up to the inauguration date of the wind tunnel strongly depends on the local conditions, the duration of required approval procedures and issuance of permits, as well as the integration of individual customer preferences and requests. Typically, the average time is approximately one year; however, this again strongly depends on the conditions noted above.
5. Does the purchase of an ISG Vertical Wind Tunnel include franchise obligations?
No. Our customers may freely operate their wind tunnel. Depending on the individually agreed payment terms, ISG receives a margin for the sale of the ISG Technical Equipment and the transfer of corresponding intellectual property rights as either (i) a one-time margin payment, (ii) a license fee, or (iii) a mix of margin and license payment. The customer undertakes to pay royalties only in the event they want to reduce the initial financing costs of the project (license instead of a one-time margin).
6. Does ISG grant exclusivity for my tunnel location?
Yes. ISG grants exclusivity for a certain tunnel location upon signing of a supply agreement for an ISG Vertical Wind Tunnel by the customer.
7. Is the ISG technology patented?
The ISG Group is the exclusive owner of patented technology regarding vertical wind tunnels. The new and inventive quality of ISG’s technology was acknowledged by the most important patent offices around the world (European Patent Office: EP 2 334 553, US Patent Office: US 8,668,497, Chinese Patent Office: CN 000102202972, Russian Patent Office: RU 2 516 947).
A vertical wind tunnel in its entirety is not a new invention and thus not patentable. First patents on vertical wind tunnels were already granted in the early thirties of the last century. As a consequence, to date only certain specific components/configurations of vertical wind tunnels may be successfully registered as patented new inventions. To the extent permitted, ISG successfully applied for patent protection for its wind tunnels.
