FFLECS

FFLECS (Novel Fuel-Flexible ultra-Low Emissions Combustion systems for Sustainable aviation is an RIA action funded by Cluster 5 of the Horizon Europe framework. In FFLECS project, revolutionary combustor architectures will be studied, and, in particular, it will advance (i) the Lean Azimuthal Flame (LEAFinnox), a novel combustion system based on Flameless Oxidation, (ii) the Compact Helically Arranged combustoR (CHAIRlift), a new system which uses interacting lean lifted flames, and (iii) plasma and electric manipulation of the spray and of the flame stabilisation mechanism. The fuel flexibility offered by these novel concepts is key to allow for SAF and H2 operations. FFLECS will include new CFD, low-order, and AI models, and novel stabilisation techniques ripe for commercial exploitation
