Extremely compact reverse flow combustor architectures are required for future turboprop engines development, where geometry and space saving are strictly linked to fuel burn and emission reduction. The target of the CfP is to adapt the available Quick-Design-Rapid-Validation methodology to this family of combustors. Design-for-additive, Virtual combustor simulation and advanced diagnostic testing, addressed to innovative architectures and cooling concepts, quick quench modules design and low soot production, shall be developed to support in a period of 18 months the achievement of the objective. Strong collaboration among the possible partners and focus on available rigs is a strong requirement of the project. Please refer to the full and formal topic descriptions published in this call.
