What facility improvements are scheduled?
The three strategic facilities each have a different, but coherent, focus on their
investments within ESWIRP.
> The ETW will improve their unsteady testing capabilities for exploring the
flight envelop limits,
> Onera-S1MA will improve the Mach number stability in the test section in
transonic domain,
> DNW-LLF is enhancing its ground simulation capability by increasing the
available moving belt velocity.
Workshops – Schedule and objectives
First workshop – Cologne – ETW facility – November 2010
� to collect a first panel of ideas – initiate the debate
Second workshop – Modane – S1MA facility – March 2011
� to consolidate from ideas to projects – potential consortia
Third workshop – Marknesse – LLF facility - October 2011
� to prepare the call for proposal
TNA - Schedule
� Call for proposal – October to December 2011
� Evaluation and selection – January and February 2012
� Test preparation and test - March 2012 to July 2013
� 4 Phases of a wind-tunnel test:
1. Outside tunnel [regular status review required]:
Get test hard- & software ready in time
2. On model cart / inside tunnel [full collaboration]:
Installation of specific tunnel equipment,
Final test setup check-out
3. “Wind on” [full collaboration]: Test conduction (between 5 to 9 days per facility)
4. Post test [support required]: Data analysis, documentation & dissemination

TNA – Available models
No budget is foreseen for model realisation or adaptation.
If the researchers need a wind tunnel model for their project, that researchers can take contact with the consortium which will study with them the various possibilities.
Expert committee
To evaluate the submitted proposals the Consortium appointed a review team
consisting of three experts from the academic, research and industry
community covering aeronautics and wind tunnel techniques.
Expert team:
> For industrial: Jean-Jacques Degeilh - Airbus – Aerodynamic senior expert
> For academic: Piotr Doerffer - Polish Academy of Sciences - Head of
department: Transonic Flows and Numerical Methods - Institute of Fluid
Flow Machinery
> For research: Horst Körner - retired from the DLR (Professor)
