The control of the thermal activity that takes place under the hood and the issue of engine cooling are important factors in vehicle design.

Do you need support in solving engine cooling or ventilation problems affecting under-the-hood components? Our CFD department is at your service.

Undertake under-the-hood thermal studies with complete peace of mind thanks to our team which has the expertise and computational resources to ensure that you achieve your aims.

Armed with considerable experience of all these sectors of activity (automotive, aeronautic, defence, off-road), our engineers and scientific staff will perform all the necessary calculations and use their expertise to optimise your designs.

However tough the environment and whatever the power and technology of the engine or the number of radiators, ACE has the contacts you need to support you in your development work.

Do you want to work on external aerodynamics in combination with under-the-hood thermal issues? Our experts will be happy to hear from you to propose a mixture of CFD and wind-tunnel solutions. Using mock-ups of radiators that are scaled to model the load losses at your own components and are equipped with upstream and downstream pressure sensors, our teams are able to examine your engine cooling problems in our wind tunnel.

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 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 !
