Large Low-Speed Wind Tunnel
Summary
The new low-speed wind tunnel facility was developed in 2019 after a two-year redevelopment project. The new test facility is designed with two aerodynamics test area and another test section designed for civil-engineering testing.
| Test Section Dimensions | 14 m (L) x 2.5 m (W) x 2 m (H) |
| Turbulence Intensity | < 0.12 % |
| Flow Uniformity | < 0.4 % |
| Flow Angularity | < 0.5 degrees |
| Working Temperature | Heat exchanger unit sets working temperature ~ 24 degrees Celcius |
| 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, capable of rotating 360 degrees. The overhead turntable is additionally capable of suspending a sting mount with a variable inclination angle controller, thereby enabling suspended aircraft models to be tested under various pitch angles.
This test section is used for:
1) Performance-sports engineering
2) Unmanned Aerial Vehicle testing
3) General aerospace research and development testing
Boundary-Layer Test Section
This test section is located towards the downstream-end of the 14 m long test section. This section 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:
1) Boundary layer research
2) Civil engineering aerodynamic testing (buildings, facade, etc.)
