Turbulence Grid

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


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)
