Braunschweig, January 2004; The European High-Lift Project EUROLIFT II was started under the co-ordination of DLR as a Specific Targeted Research Project (STReP) of the 6th EU framework program. The Project continues the successful work of the predecessor project EUROLIFT I under the leadership of Airbus-Deutschland with a moderately increased total-budget of 7.3 million EURO. Besides the successful acquisition of about 1.5 million EURO for DLR, the German competence for high-lift systems is supported. In view of the realization of the demanding targets of the European vision 2020 high lift systems will deliver a substantial contribution, to make the aircraft system more efficient and environmentally friendly. Corresponding potentials of the high-lift system are the aerodynamic efficiency-increase with reduced maintenance effort, the development of more efficient theoretical and experimental methods for the industrial design process, and the reduction of the noise emission in the start and landing phase by advanced high-lift concepts. This can only be achieved, when modern numerical and experimental methods are available, which can be used for the analysis of the dominant aerodynamic phenomena as well as for the high-lift design and optimization in real flight conditions.

With the EU-project EUROLIFT II, these methods and the physical understanding of the dominant aerodynamic phenomena should be brought to a level, which guarantees the solution of the envisaged tasks. The following objectives are set:

  • Validation of numerical and theoretical methods for exact prediction of the aerodynamics of a complete aircraft in high-lift configuration at flight Re-numbers.
  • Numerical and experimental analysis of the physical interaction of the different, vortex dominanted aerodynamics as well as their effect on the aerodynamic performance. This will be accomplished by using state-of-the art RANS-methods (Reynolds-averaged Navier-Stokes) and also the wind tunnels ETW (European Transonic Wind Tunnel) and LSWT (Low Speed wind tunnel) of Airbus Germany.
  • Specification of progressive high-lift systems including numerical as well as experimental demonstration.

The DLR Institute of Aerodynamics and Flow Technology coordinates the project EUROLIFT II. The consortium of 14 partners includes the European Airframe industry and the European research institutions as well as two SMEs:

  • DLR, Deutsches Zentrum für Luft- und Raumfahrt e.V., Germany
  • Airbus Germany, Airbus France, Airbus United Kingdom
  • Alenia Aeronautica S.p.A., Italy
  • Dassault Aviation, France
  • ETW, European Transonic Wind Tunnel, Germany
  • CIRA, Centro Italiano Ricerche Aerospaziali S.C.p.A., Italy
  • FOI, Swedish Defense Research Agency, Sweden
  • INTA, Instituto National de Tecnica Aerospacial, Spain
  • NLR, Stichting Nationaal Lucht- en Ruimtevaart Laboratorium, Netherlands
  • ONERA, Office National d’Etudes et de Recherces Aerospatiales, France
  • ICAROS Computing Ltd., Greece
  • Engineering Office Dr. Kretschmar, Germany

EUROLIFT II has got a total run time of 36 months and will end in December 2006.
