Developing hybrid digital twins

This chair will develop hybrid digital twins capable of operating in real time, using model reduction techniques made possible by scientific machine learning, which combines scientific computing and machine learning techniques using artificial intelligence. These models will then be used in all phases of the machines' life cycle, from conception and design to validation. Simulation will optimize testing and thus improve manufacturing processes.

φML also provides the Arts et Métiers group with an opportunity Arts et Métiers an R&D facility for conducting tests at the "Espace campus" in Vernon (27).

This chair is headed by Chady Ghnatios, a specialist in simulation and digital twins. He develops model reduction techniques, hybrid twins, and data-driven models, with applications in composite materials.

Better characterize the risk of default

Launched in June 2023, the aim of this chair is to optimize the supervision and maintenance of the French electricity transmission network: in order to accelerate the energy transition while controlling daily risks to the network, it is essential to adjust maintenance on electricity network infrastructure.

To monitor the operation of this equipment and implement appropriate maintenance operations, a process for digitizing and centralizing information and equipment dedicated to network monitoring is necessary.

 Physical models necessarily differ from reality. Furthermore, it is unrealistic to imagine that knowledge can be based exclusively on collected data, as this would require too much data! We therefore start with the physical model and, as soon as it differs from the collected data, we use AI to create a model of this discrepancy based on the data.

Professors Francisco Chinesta and Xavier Kestelyn, coordinators of the CHIMERA Chair

The work carried out by the CHIMERA chair will contribute to furthering this approach by jointly modeling these data and physics in order to better predict the individualized states of a facility throughout its life cycle. For RTE, this is a way of better characterizing the risk of failure by taking into account aging as well as the actual operation of each piece of equipment.

The result of a long-standing collaboration

This research chair, launched in April 2023 and scheduled to run for five years, will help lay the foundations for the aviation of the future. Its goal is to meet the challenge of completely decarbonizing aviation by 2050. To achieve this, Arts et Métiers from the support of aerospace leader Safran, with whom it has been collaborating on research projects for several years. 

Together, the two groups will work on creating a new environmentally friendly aircraft engine, focusing this chair on several areas:

• Significant advances in centrifugal pump design
• Ensure their reliability
• Developing carbon-free components and systems
• Optimizing energy consumption

The expertise of the LIFSE laboratory

The BELISAMA chair will benefit from the human and material resources of the LIFSE laboratory (Fluid Engineering and Energy Systems) to carry out experiments and test benches. Specializing in hydrodynamics and aerodynamics, the laboratory conducts research in the fields of renewable energy, sustainable mobility, aeronautics, and space. LIFSE also has a 2,500 m² state-of-the-art technology platform that will be used by researchers and engineers for experimental purposes.

The excellence of this collaboration was recognized at the latest SAFRAN A.E. R&T Days, where LIFSE and AMValor received the prestigious "Partnership Development" award on behalf of Arts et Métiers.
