Versatile ice wind tunnel from Baltic Windtunnel – made entirely of stainless steel – cooled by two cooling units

Highlights Measurements at speeds of up to 38 m/s and temperatures of -20…40°C High contraction of 9 Large, clearly visible measuring chamber

The core of the WT342E ice wind tunnel is an Eifel-style wind tunnel. It is made entirely of stainless steel (untreated frame, ground sheet metal parts). This means that the WT342E is protected against corrosion caused by condensation in cooling mode.

To suppress turbulence, the wind tunnel has a honeycomb rectifier in a honeycomb cassette, followed by three strainers. 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 to the vibration-decoupled axial fan in the shortest possible installation space.

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

The system is controlled centrally via the proven BWT-Control wind tunnel control system, conveniently via touch panel.
