40 Years German-Dutch Wind Tunnels
The document chronicles the 40-year history of the German-Dutch Wind Tunnels (DNW), highlighting its evolution from a European cooperative project to a global leader in wind tunnel testing.
Establishment and Early Development
DNW was established on June 30, 1976, as a joint venture between the Netherlands Aerospace Centre (NLR) and the German Aerospace Center (DLR). The foundation aimed to develop a large atmospheric low-speed wind tunnel, combining efforts from both countries. Initial discussions began in 1973, leading to a formal agreement and the start of construction in 1976.
Key Milestones
- 1978: First Advisory Committee Meeting.
- 1979: First operational directors appointed; first wind-on LLF.
- 1980: Ceremonial opening of DNW.
- 1982: First TPS test with Airbus A300 model.
- 1996: Integration of LST and NWB into DNW; ISO 9001 certification of LLF.
- 2000: Full integration of DLR and NLR tunnels into DNW.
- 2016: Celebration of 40 years of DNW.
Technological Advancements
DNW has continuously upgraded its facilities, including automation of administration, fan drive modernization, and acoustic upgrades. These advancements have supported various industries, including aeronautical, automotive, and civil engineering.
Global Leadership
DNW operates eleven wind tunnels across five sites in the Netherlands and Germany, offering subsonic, transonic, and supersonic testing capabilities. It serves both the research community and industrial development projects, contributing to the success of major aerospace programs like Airbus and Eurofighter.
Conclusion
Over four decades, DNW has established itself as a leading non-profit foundation in wind tunnel testing, providing critical support to the aeronautical industry and beyond.

40 YEARS GERMAN - DUTCH WIND TUNNELS - from European cooperation to global leadership - On the 30th of June 1976 the Duits-Nederlandse Windtunnel / Deutsch-Niederlandischer Windkanal (German-Dutch wind tunnel DNW) was established as a foundation, only two years after first contacts between the two parent institutes, the Netherlands and German Aerospace Centers NLR and DLR. This milestone, achieved with the support of the German and the Netherlands governments, marks the start of the first joint venture in Europe operating a large aeronautical facility: a European collaboration 'avant-la-lettre'....
