The first pioneers
|Otto Lilienthal achieves the first human flight with his single-wing glider. He completes 2,000 successful flights before dying in an accident.|
|First intensive research and development work on dirigible airships; Count Zeppelin shows immense entrepreneurial courage and advances to the forefront of the airship movement.|
|1903||First motorised flight by the Wright brothers in the USA. At the same time, the German Karl Jatho from Hannover also performs the first successful aerial hops with a motorised apparatus. But he does not manage to control his machine in flight. Gustav Weißkopf from Leutershausen in Franconia, who had emigrated to the USA and was known there as Gustav Whitehead, is alleged to have completed several flights with a motorised flying machine in 1901, narrowly beating the Wright brothers at the post. But as there is no photographic or film evidence, the honour of completing the first documented motorised flight still goes to the Wright brothers.|
|1904||Prof. Ludwig Prandtl drafts his pioneering theory of extremely low-friction flows, which becomes known as the 'boundary layer theory'.|
|1907||Foundation of the Modellversuchsanstalt der Motorluftschiff-Studiengesellschaft (MVA, Institute of Model Testing of the Motorised Airship Study Society) in Göttingen. First closed loop wind tunnel, also known as the ‘Göttingen-type’ wind tunnel. This wind tunnel design inspires thousands more throughout the world.|

It marks his first description of the relationships between airfoil lift and drag, as well as the formation of vortices behind an airfoil. Leading aerodynamic researchers regard it as one of Prandtl’s greatest scientific accomplishments.

This talk was a monumental moment in aviation research and has decisively influenced high-speed aerodynamics to the present day.
