Testing Capabilities

ONERA wind tunnel facilities

 

ONERA Wind Tunnel Division offers a large panel of wind tunnels, for aerodynamic and acoustic test, covering very low Mach number to hypersonic Mach numbers.

Wind tunnels are located in 3 different areas in France: Modane-Avrieux, Le Fauga-Mauzac (near Toulouse) and Saclay (close to Paris).

  • 5 continuous wind tunnel covering Low speed (few m/s) up to Mach 3.1,
  • 3 blow-down wind tunnels covering Mach 0.1 up to Mach 12,
  • 2 additional wind tunnels for specific applications.

                                                   A wind tunnel for every type of test
