IMPACT-AE - Intelligent Design Methodologies for Low Pollutant Combustors for Aero-Engines
Overview
Background & policy context:
Environmental benefits of low emissions lean burn technology in reducing NOx emissions up to 80%, will only be effective when these are deployed to a large range of new aero-engine applications. While integrating and developing low emission combustion design rules, IMPACT-AE will deliver novel combustion chamber design methodologies for advanced engine architectures and thermodynamic cycles.
Objectives:
The IMPACT-AE project will support European engine manufacturers to pick up and keep pace with US competitors, being already able to exploit their new low emission combustion technology to various engine applications with short turn-around times.
Key element of the project will be the development and validation of design methods for low emissions combustion chambers to reduce NOx and CO emissions by optimisation of the combustion chamber aero-design process.
Methodology:
Preliminary combustion chamber design tools will be coupled with advanced parameterisation and automation tools. Improved heat transfer and NOx models will increase the accuracy of the numerical prediction. The advanced representation of low emission combustion chambers and the capability to investigate combustion chamber scaling effects, allow an efficient optimisation of future combustion chambers targeting a cut of combustion chamber development time by 50%.
IMPACT-AE is split into four technical work packages:
- WP1Development of smart design methodologies for clean combustion as central WP to deliver the new methodology for combustion chamber design;
- WP2Modelling and design of advanced combustion chamber wall cooling concepts for combustion chamber liner design definition as key technology area;
- WP3Technology validation by detailed flame diagnostics to substantiate fuel injector design rules implemented into the design methodology;
- WP4Methodology demonstration for efficient low NOx combustion chambers will validate the combustion chamber design.
The consortium consists of all major aero-engine manufactures in Europe, 7 universities and 3 research establishments with recognised experience in low emission combustion research and 10 SMEs.
