DLR - German Aerospace Center
DLR Research Projects, a contribution to the Vision 2020
Rainer Scharenberg, 1 Historical roots
1907 – founding of the „Modellversuchsanstalt der Motorluftschiff- Studiengesellschaft“ - Research Facility for the „Airship development society“, later the „Aerodynamische Versuchsanstalt Göttingen“ AVA
1989 – transformation of the DFVLR in Deutsche Forschungsanstalt für Luft- und Raumfahrt (DLR) Founding of the German Space Agency „Deutsche Agentur für Raumfahrtangelegenheiten“ DARA
1997 integration of the DARA into the DLR with all their political functions. Since 1997 DLR means „German Aerospace Centre“
