Technische Daten



Blower Motor

- Power at 400 V a.c.: 16,000 W
- Min. wind speed: 0.3m/s
- Max wind speed: 16.0 m/s (small cross-section)
- Max wind speed: 12.0 m/s (large cross-section)
- The wind speed control is infinitely variable.

Measuring Zone Dimensions

- Height above floor level 0.9m
- Large cross-section (BxH) 2.00x1.00 m
- Small cross-section (BxH) 1.20x1.00 m
- Length 2.00m



Anchorage Points

The positioning jig has a base plate with a grid array (500 x 250 mm) of M6 thread attachment points, suitable for any type of experiment.



The floor has a brass plate with four M10 thread attachment points. These four points are used to set up the positioning jig, for which reason they are covered. In addition, all corners of the measuring zone have stout eyes for straps that secure and hold the model during test and measurement.



Air Flow Quality

When operated in the small cross-sectional mode in the speed range 4 to 16 m/s, the airflow quality is always better than (Geschwindigkeitprofil = Speed Profile):



When operated in the large cross-sectional mode in the speed range 4 to 11 m/s, the airflow quality is always better than:


Access

Samples brought for testing in the Focke Wind Tunnel must be introduced through a narrow passage with corners and a door 90 cm wide. Prior to assembly, individual components should not be larger than 1200 x 800 (as seen in plan view) and not more than 1600 mm high. A trolley capable of carrying up to 400 kg is available for use in the wind tunnel hall.
