F2 Wind Tunnel overview


The F2 subsonic continuous flow wind tunnel is a research facility allowing the use of large size models.

Sting set-up
Motorised floor turret
  • Test section dimensions:
    • length: 5 m,
    • width: 1.4 m,
    • height: 1.8 m.
  • The wind tunnel is equipped with a 12 bladed fan driven by a 680 kW direct current motor. The velocity can be continuously varied from 0 to 100 m/s by adjusting the motor speed.
  • The total temperature is controlled in ± 1°C by a water cooler.
  • The settling chamber is equipped with 4 screens, a honeycomb filter, and noise dampers on walls, which, in conjunction with a contraction ratio of 12, supply a flow with a very low level of turbulence in the test section (less than 0.05 %).


PIV visualization


  • The wind tunnel is well adapted to study complex flow phenomena (three dimensional boundary layer, separations, wakes).
  • Transition surveys.
  • Airfoil studies between walls.
  • Probe calibration.
