Deutsche Versuchsanstalt für Luftfahrt

Did the wind whisper secrets of flight here? We stand before the remnants of the Deutsche Versuchsanstalt für Luftfahrt (DVL), a place where the future of flight was once imagined and engineered. The DVL, founded in Berlin in 1912, was Germany’s central research and development institution for aviation. It played a crucial role in shaping the nation’s aeronautical advancements, a precursor to today’s German Aerospace Center (DLR). This institution, initially a response to similar establishments in France and Great Britain, was championed by Count Ferdinand von Zeppelin. It gained significant traction after a 1911 military demonstration highlighted the strategic importance of air power. The DVL’s very foundation reflected this military focus. Its founding members included not only scientific and technical organizations but also the War Ministry and arms manufacturers. Initially led by Colonel Hugo Schmiedecke, the DVL soon transitioned to the leadership of Lieutenant General Hermann Rieß von Scheurnschloß. He guided the institution until the outbreak of World War I in 1914, a conflict that would profoundly shape the DVL’s trajectory. Located at the Johannisthal-Adlershof airfield, the DVL’s work took on a distinctly military focus during the World Wars and the preceding periods of military buildup. From 1934 onwards, it fell under the direct control of the Reich Air Ministry. The DVL’s Adlershof location became a hub of activity. It housed cutting-edge testing facilities, including the Large Wind Tunnel, the soundproofed engine test stand with its prominent towers, and the iconic egg-shaped spin tunnel. This spin tunnel was particularly remarkable. Here, aircraft models were suspended in mid-air within the 20-meter high wind tunnel, their flight and spin characteristics meticulously filmed. The data gleaned from these experiments directly influenced the development of fighter aircraft for the Luftwaffe. The DVL also commissioned Lorenz to develop the “Sonne” radio navigation system. Under Ernst Ludwig Kramar’s leadership, this system became a vital tool during World War II, later evolving into the “Consol” system. After 1945, the DVL’s Adlershof site fell within the Soviet occupation zone. Parts of it were integrated into the Academy of Sciences of the GDR’s Berlin-Adlershof location, eventually becoming part of the Adlershof Science and Technology Park (WISTA). The DVL’s legacy continued in West Germany, initially operating from Essen/Mülheim Airport before finally settling at Cologne-Bonn Airport. It eventually merged with other institutions to form the DFVLR and later the DLR, continuing Germany’s rich tradition of aerospace research and development.
