The goal is to add turbulence to the full scale wind tunnel flow in order to simulate road driving conditions.

• Installation time : 25mn.
• De-installation time : 20mn.
• Turbulence rate without grid : 0.3%
• Turbulence rate with grid : 4.5%

Testing requirements

• Minimal S2A staff : 2 wind tunnel technicians.
• Dedicated windspeed calibration law to be implemented
• Vmax=120km/h

Analysis

The S2A team proposes as standard:

• Aerodynamic coefficients measurement w/wo turbulence grid

• Flow surface topology: 3D velocity vector / Total+ static pressure (18hole anemocline probes)
