was a sportsplane of Germany

(academic group of flyers) of Darmstadt University of Technology
. It was a development of Darmstadt D-18
, slightly enlarged, more streamlined and fitted with an inline engine. Thanks to strengthening it was better fit to aerobatics. Two were built in 1931.
Just like D-18, the plane had quite unorthodox layout, being a cantilever biplane, with an upper wing placed low above a fuselage and ahead of a lower wing. A stress was put upon aerodynamics and lightness and the plane was small, with a streamlined silhouette.
One plane, in D-22a variant, took part in the Challenge 1932
international tourist plane contest, piloted by Walter Marienfeld. It was handicapped in technical trials, especially short landing trial, not having wing mechanization, and took the 35th place after this part (for 43 aircraft). It improved its score after a rally around Europe, where it took the 4th place, with a cruise speed 205 km/h. In a maximum speed trial it was beaten only by five Heinkel He 64s
, reaching 230.7 km/h. As a result, it completed the contest on the 17th place. This plane carried registration D-2222, from 1933: D-EQIN. It was used several year... Read More
