Deutsches Zentrum für Luft- und Raumfahrt e.V. CLOSE

DLR is the German National Aerospace Research Centre as well as the German Space Agency.

DLR’s mission comprises the exploration of the Earth and the Universe, research for the conservation of the environment, for environment-compatible technologies, for promoting mobility, communication, and safety. DLR operates major research institution facilities for DLR’s own projects and as a service provider for clients and partners. Approximately 8000 people are employed in total in DLR’s 36 institutes at 20 locations distributed over Germany, including Köln (Headquarters) and Stuttgart.

The Institute of Combustion Technology is using synergies from the groups ‘Advanced Diagnostics’, ‘Chemical Kinetics’, ‘Numerical Simulation’ and ‘Multiphase Flows and Alternative Fuels’. VT has organized the sourcing and logistics of 110 tons of alternative Jet A-1 to fly the research aircraft ATRA for 30 hours of test flight during which in-situ emissions and ice particles measurements were performed (DLR ECLIF project).Moreover, its lab-scale and semi-technical facilities together with modeling and simulation experience has been applied in many European and National projects towards fuel characterisation, combustion diagnostics including generating precious validation datasets, and reactive flow simulation results.

The institute for Simulation and Software Technology (DLR-SC) is the central DLR institute for software engineering. The institute’s mission is research and development in software engineering technologies, and the incorporation of these technologies into DLR software projects. DLR Simulation and Software Technology has a long history and working experience in the field of distributed systems, concurrent engineering, and graphical user interfaces, mainly in the development of design and simulation systems for engineering applications and distributed support tools for engineers and developers of numerical simulation software.

Role in the project

DLR coordinates the JETSCREEN project and is consequently assigend to WP 9. Furthermoe, DLR leads the WP8  aiming at the development of screening and optimization methods for alternative aviation fuels. Besides that DLR will contribute to chemical and physical property modeling (WP2), experimental characterization and numerical prediction of fuels effects on fuel preparation (WP4), on lean blow out (WP6) and NOx emissions (WP7). 

Personnel involved

Patrick Le Clercq (Dr. ès sc.) is head of the Department Multiphase Flow and Alternative Fuels at the DLR, Institute of Combustion Technology, Stuttgart. Much of his research activity focuses on modeling and interpreting complex fuel’s properties and effect on spray characteristics and combustion sub-processes. The main application is in investigating the suitability of alternative fuels in the aviation sector. He has been involved in several fuels research program: ALFA-BIRD (EU), SWAFEA (EU), InnoTreib (D), QSTP (International), Bio@Jet (D) and is currently leading ECLIF (DLR).

Bastian Rauch (m) 10 years of experience in experimental and numerical investigations of alternative aviation fuels effects on combustion systems. Bastian Rauch was the project coordinator of the project “InnoTreib” – Innovative fuels for the future (2014-2016). In InnoTreib different methods for fuel screening and optimization utilizing distributed models have been sucessfully tested.
