About: Heinkel HD 21

An Entity of Type: person, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

The Heinkel HD 21 was a trainer built in Germany during the 1920s. It was a conventional single-bay biplane with staggered wings braced with N-type interplane struts. The main units of the fixed, tailskid undercarriage were linked by a cross-axle, and the aircraft had three open cockpits in tandem, although one of these was typically faired over. The HD 29 of 1925 was essentially similar, but was purely a two-seater.

The HD 29 of 1925 was essentially similar, but was purely a two-seater. One HD 21 (registered SE-ACY) was flown as an air ambulance by Carl Gustaf von Rosen for the Red Cross during the Italian invasion of Abyssinia in 1935. Others were flown by the Reichswehr at the clandestine aviation training facility in Lipetsk. (en)
  • L'Heinkel HD 21 fu un aereo da addestramento biposto, monomotore e biplano, sviluppato dall'azienda aeronautica tedesca Ernst Heinkel Flugzeugwerke nei primi anni venti del XX secolo. Benché sviluppato ufficialmente per il nascente mercato dell'aviazione commerciale nell'allora Repubblica di Weimar, venne clandestinamente impiegato anche come addestratore militare per la formazione degli equipaggi del Reichswehr, le forze armate tedesche di difesa istituite dopo il termine della prima guerra mondiale, presso l'aeroporto di Lipeck, in Unione Sovietica.
