Versatile ice wind tunnel of the Baltic Wind Tunnel – made entirely of stainless steel – cooled by two cooling units

  • Measurements at speeds up to 38 m/s and temperatures from -20…40°C
  • high contraction of 9
  • large, easily visible test section
The core of the WT342E ice wind tunnel is a wind tunnel based on the Eifel design. This is completely made of stainless steel (frame raw, sheet metal parts ground). This means that the WT342E is protected against corrosion caused by condensation during cooling operation.

To suppress turbulence, the wind tunnel has a honeycomb rectifier in a honeycomb cassette, followed by three screens. These are accessible for cleaning via inspection flaps.
The nozzle with a contraction of 9 accelerates the flow in the 400 x 400 x 1000 mm measuring chamber to up to 38 m/s (137 km/h).

The ingenious design of the diffuser enables the flow to be guided without detachment to the vibration-decoupled axial fan in the shortest possible space.

The temperature of the air in the cold room, in which the WT342E works, is controlled by two cooling units. This makes it possible to carry out aerodynamic measurements in the temperature range from -25…40 °C.

The system is controlled centrally via the proven wind tunnel control system BWT-Control, comforatbly via Touchpanel.
