The flapping-wing-apparatus of Altwigshagen near Anklam
Illustration from Lilienthal's book: It ingenuously shows the principle and the result, as well as important details (such as the suspension of the pedals).
Lilienthal 1889: "Bird flight as the basis of aviation", Fig. 10
Replica of the measuring apparatus, modeled after a drawing by Lilienthal. It was fixed on a barn wall for film shots of the museum. Lilienthal’s result: he could lift 40 kg at full effort by beating the wings.
