Dr Stefan Görtz – DLR Institute of Aerodynamics and Flow Technology

32713-gortz-stefanDr. Görtz earned his M.Sc. in Mechanical Engineering from Darmstadt University of Technology, Germany, and his M.Sc. in Vehicle Engineering and his Ph.D. in Aeronautical Engineering from the Royal Institute of Technology (KTH), Sweden. After a short-term research position at the Swedish Defence Research Agency (FOI), he performed his post-doctoral research at the US Air Force Academy.

Dr. Görtz joined DLR’s Institute of Aerodynamics and Flow Technology in 2006. He is the head of the Aerodynamic Surrogates and Optimization Group, which is part of the Center for Computer Applications in AeroSpace Science and Engineering (C²A²S²E).

He is the principle investigator of the DLR project VicToria (Virtual Aircraft Technology Integration Platform), which addresses DLR’s guiding concept “The Virtual Product” and aims at virtualizing the aircraft design, development and manufacturing processes, including the definition of an appropriate validation strategy.

His present research interests are in numerical methods for predicting aerodynamic data for loads, handling qualities and performance based on high-fidelity CFD, including surrogate and reduced modelling methods, in methods for uncertainty quantification and robust design, and in collaborative multi-disciplinary optimization.
