... tests with Lilienthal’s large biplane.VI. ConclusionsOtto Lilienthal’s patented monoplane glider (Normalsegelapparat) was flown reliably and steadily downhill over distances of up to 72 m. The static margin of the glider as laid out in the patent drawings of Lilienthal can safely be flown by a person with ...

... wind-tunnel test of a replica of Otto Lilienthal’s Normalsegelapparat from 1893 was conducted in a closed low-speed wind tunnel. The goal was to determine the flight performance and characteristics of this glider for the first time. It is of particular interest to this investigation to resolve the open question about the design’s static stability and to clear up whether Lilienthal treated the cloth covering the wings. Therefore, tests ...

Lilienthal’s manned aircraft were experimental tools for him. They were changed and altered during the course of his research and testing. We know of nine different glider models from photos, while ideas and construction plans exist for other designs. Only the Sturmflügelapparat and restoration or fragments of four examples of the Normalsegelapparat have been preserved to this day.
