Safran Industrial Research Chair on the Development of Sustainable Aero-Propulsion Systems

About the Chair

The aviation industry generates more than 2% of all greenhouse gases produced by human beings worldwide. The team at the Safran Industrial Research Chair on the Development of Sustainable Aero-Propulsion Systems is working to design cleaner aircraft engines with a view to reducing its environmental footprint.

This work will lead to a greater understanding of the physicochemical processes at play in the formation of pollutant emissions. In addition, the physicochemical modeling tools that are developed will be used to analyze the volatile and non-volatile particles that are ejected into the atmosphere.

Research

The Chair is focusing on the following areas to advance the state of knowledge related to fine and ultrafine particles generated by aircraft engines:

  • Using modeling to better understand the dynamics of aerosols and their gaseous precursors;
  • Developing models to simulate the dispersion of aircraft engine exhaust into the atmosphere;
  • Seeking to better understand the links between fluid mechanics and microphysics in the creation of particles, especially those formed in turbines, nozzles and aircraft engine outputs;
  • Using experimental data to calibrate models that reflect reality as accurately as possible;
  • Developing digital tools for designing aircraft engines that emit fewer fine and ultrafine particles.
