ICWM2009 > Arne Bachmann > Markus Kunde > Markus Litz > Slide 2 Overview German Aerospace Center (DLR) Challenge Approach Conclusion & Outlook

ICWM2009 > Arne Bachmann > Markus Kunde > Markus Litz > Slide 3 The DLR German Aerospace Research Center Space Agency of the Federal Republic of Germany

ICWM2009 > Arne Bachmann > Markus Kunde > Markus Litz > Slide 4 6,000 employees working in 29 research institutes and facilities at 13 sites. Offices in Brussels, Paris and Washington. Köln Lampoldshausen Stuttgart Oberpfaffenhofen Braunschweig Göttingen Berlin- Bonn Trauen Hamburg Neustrelitz Weilheim Bremen- Sites and employees

ICWM2009 > Arne Bachmann > Markus Kunde > Markus Litz > Slide 5 Mission To open up new dimensions for exploring the earth and the universe, for protecting the environment and for promoting mobility, communication and security: Research portfolio ranging from basic research to innovative applications and the products of tomorrow Operating large-scale research facilities for DLRs own projects and as a service provider for its clients and partners Promoting the next generation of scientists Advisory services to government

ICWM2009 > Arne Bachmann > Markus Kunde > Markus Litz > Slide 6 Challenge Preliminary design in aviation Iterative development of aircraft Duration: Minutes; Hours; Few days Target: Complete aircraft or components Pre-Design is an interdisciplinary task Different domains (in our case: institutes/departments) Problems No omniscient person Usage of external knowledge Reuse of existing applications

ICWM2009 > Arne Bachmann > Markus Kunde > Markus Litz > Slide 7 Goal Under development at DLR in the following aeronautics projects: TIVA I/IITechnology integration for the virtual aircraft UCAV 2010Unmanned combat air vehicle EVITAEvaluation of innovative turbine engines CATSClimate-compatible air transport system … and more to come! A DLR-wide system to enable the multi-disciplinary design and analysis of airplane configurations in the pre-design phase.
