With or without a moving surface, with or without turntable, our wind tunnel is perfectly suited to meeting a wide range of requirements. Aeronautics, automotive, research, sport, wind power, etc. are all sectors of activity whose efficiency of their products can be improved by tests performed in our wind tunnel.

Wind tunnel

Specifications of our wind tunnel

  • Configuration : single return closed-circuit
  • Power : 250 kW
  • Contraction Ratio : 7
  • Speed: from 7 to 40 m/s
  • Turbulence Intensity: 0.2% at 40 m/s
  • Test Section:
    • Length: 4750mm
    • Width: 2300mm
    • Height: 2050mm
    • Type: closed
  • Equipment:
    • Pressure : Scanivalve ZOC ( channels available)
    • Smoke visualization
    • Oil-flow visualization
    • PIV : Possibility to use your own PIV system or external services

Full plane configuration:

  • Models: up to 1.5m span
  • Pitch, Yaw: integrated in the model
  • Take-Off and Landing simulation: Thanks to the 2-stages boundary layer suction, the Rolling Belt(1.5m wide) and the Z-displacement of the strut, we are able to simulate true ground effect during take-off and landing at several altitudes.
  • Forces and moments measurement: several 6-components balances.
  • Rotating propeller with possibility of torque and thrust measurement.
  • Actuated control surfaces during the test to reduce time spent for flight envelope exploration.


Half plane configuration:

  • Models: up to 1.5m semi-span
  • Pitch: from -30° to 30°
  • Boundary layer: 2-stages boundary layer suction in front of the model reducing the height of the boundary layer close to the model, reducing the necessity of using a peniche (still possible if required).
  • Forces and moments measurement: 3-components system with the possibility to choose any of the three components range to match your requirements.
  • Actuated control surfaces during the tests to reduce time spent for flight envelope exploration.
  • Models: up to 60% scale
  • Forces and moments measurement: several 6-components balances and 3-components balances for separated measurement (e.g. front and rear wings)
  • Rolling belt: up to 40m/s
    • Length: 3010mm
    • Width: 1500mm
    • Temperature regulation
  • Model displacement :
    • Pitch, Roll motorized (laser controlled)
    • Yaw: +/- 6°
    • Steer: 7°
  • Wheels: attached to the model or to separate struts for individual drag measurement.

Our areas of expertise


Coming from the world of motor sports and based in the technology centre of the Magny Cours circuit, the Aero Concept Engineering team is deeply immersed in the automotive world. From motor sports to series production, along with the world of non-standard vehicles, ACE has contributed its expertise to numerous automotive projects.


Our engineers have been involved in aeronautic projects for many years. They have studied certified aircraft, ultralight aircraft (ULMs), drones and even airships using CFD techniques or in the wind tunnel.


Since HGVs, construction machinery and agricultural machinery are subject to aerodynamic and thermal problems very similar to those affecting passenger cars, our teams are regularly called upon to work in these fields.


Pantographs, landing doors, carriage doors, train tunnel entries, crossings, air conditioning… These are just a few examples of the railway-related topics that we have been asked to address.


Are you responsible for the construction of a new district or a new building? Do you want to make sure that the aeraulic and thermal issues are dealt with prior to the construction work? Then please contact us!


Whether earthbound or airborne, armoured or not, take advantage of our experience to optimise the thermal and aerodynamic aspects of your military vehicles.

Sports and Records

Make your entry into the world of ultimate performance thanks to our sports-dedicated entity aeroptimum.fr. Our aerodynamic engineers will help you get the very best out of your machine and open the way to records, medals and victories!


Research has been one of our sectors of activity for many years. With our wind-tunnel tests, the design of mock-ups and our expertise in CFD, we have cooperated in the preparation of many theses and dissertations.


Do your industrial processes or products involve thermal considerations, aeraulics or fluid mechanics? Would you benefit from support in their development and optimisation ? Then please contact us !
