Acoustically optimised Large Wind Tunnel

The acoustically optimised large scale wind tunnel with its specific design is particularly apt for aero-acoustic research & development projects. It also allows for testing on comparatively large components and realistic models. Calibration and function tests of wind measurement sensors at high flow velocities are also possible, just as the use for R&D projects for the industry as well as for scientific institutions.

  • Test Section Dimensions:
  • 1.) Closed measuring section (LxWxH = 2.75m x 1.25m x 5m). Vmax = 100 m/s
  • 2.) ¾ Open measuring section (LxWxH = 4m x 2.8m x12m). Vmax = 40 m/s
  • 360-degree polars possible with simultaneous pressure and force measurement, at Reynolds Numbers up to 1x10^6 (Measurements from different angles of attack)
  • Redundant measurement system
  • Degree of Turbulence is less than 0.4%
  • Velocity Deviation in the airflow is very low: less than or = 0.5%
