The methods and tools developed in Soprano are applied to current and future “semi-industrial” configurations that are representative of real-life conditions. This will help the design of future aircraft combustion systems capable of reducing soot emissions, while maintaining performance in terms of regulated gas emissions and durability.

In a first basic research phase, Soprano’s activities intend to investigate both soot formation and thermal cooling fields, with a particular interest on soot radiative effects on the combustor walls. Then an applied research phase aims at delivering more accurate methodologies for predicting the soot emissions in semi-technical systems. All these investigations are performed inside the combustor (in situ diagnostics) to understand the soot formation processes and impacts from the source.
