Lilienthal's biplane glider in flight

The air­craft trav­elled up to 100 me­tres – from the dunes to the ocean.

Flow test in the wind tunnel

The Lilien­thal con­struc­tion must be proven in flow tests in­side the DNW wind tun­nel in the Nether­lands, Mark­nesse. In the low­er left cor­ner of the im­age is the an­gle of align­ment of the front of the glid­er with the wind. The CP scale on the right side de­scribes the air re­sis­tance.

One hundred and twenty-five years of human flight. Otto Lilienthal was a pioneer of aeronautics. He was the first to recognise and document that a curved wing can generate more lift than a flat one – possibly even over twice as much. Researchers at the German Aerospace Center (DLR) reconstructed his 'normal glider' in accordance with the original plans. The DLR Institute of Aerodynamics and Flow Technology investigated the aerodynamic properties of the first series-produced aircraft in a wind tunnel and was able to confirm Lilienthal as the forefather of modern aeronautics.
