Large Low-Speed Wind Tunnel
Summary
The new low-speed wind tunnel facility was developed in 2019 after a two-year redevelopment project. The test facility is designed with two aerodynamics test areas and another test section dedicated to civil-engineering testing.
Technical details
- Test section dimensions: 14 m (L) × 2.5 m (W) × 2 m (H)
- Turbulence intensity: < 0.12%
- Flow uniformity: < 0.4%
- Flow angularity: < 0.5°
- Working temperature: Heat exchanger unit sets working temperature to about 24 °C
- Test speeds: 2.5 m/s to 40 m/s
- Background noise: LAeq < 58 dB at 5 m/s
Aerodynamic test section
The aerodynamic test section consists of two turntable units, each capable of rotating 360 degrees. The overhead turntable can additionally suspend a sting mount with a variable inclination-angle controller, which enables suspended aircraft models to be tested under various pitch angles.
This test section is used for:
- Performance-sports engineering
- Unmanned Aerial Vehicle testing
- General aerospace research and development testing
Boundary-layer test section
The boundary-layer test section is located towards the downstream end of the 14 m long test section. It consists of a base turntable, capable of rotating 360 degrees, and is surrounded by two large glass panels that provide optical access.
This test section is used for:
- Boundary-layer research
- Civil engineering aerodynamic testing (buildings, façade, etc.)
