Heinkel HD 17
|Manufacturer||Svenska Aero AB|
The Heinkel HD 17 was a conventional single-bay biplane with strongly staggered wings of unequal span braced with N-type interplane struts. The pilot and observer sat in tandem, open cockpits, and the main units of the fixed, tailskid undercarriage were linked by a cross-axle.
The Heinkel HD 17 first flew in 1924. In 1926, it was evaluated by the Reichswehr to equip the secret aviation training school at Lipetsk, and was selected in favour of the competing Albatros L 65. Seven aircraft were purchased and used briefly for training until replaced by more modern designs.
