3. Conclusion

Significant scientific and technological progress has been made in recent decades, enabling the design of ever more efficient aeronautical combustors while limiting the production of polluting chemical species such as NO _x . However, the future of air transport can only be envisaged in terms of its decarbonization, effectively ruling out the use of jet fuel of fossil origin. As a result, profound transformations will be necessary over the coming decades, impacting the aircraft as a whole. In this context, the combustion chamber, which is subject to numerous and sometimes conflicting design constraints (stability and pollutant emissions, for example) and operates in a particularly harsh environment, is the focus of multiple challenges.

To answer this question, it is essential to begin by identifying and understanding the...
