The Rumpler D.I (factory designation 8D1) was a fighter-reconnaissance aircraft produced in Germany at the end of World War I.[1] It was a conventional single-bay biplane with wings of unequal span braced by I-struts.[2] It featured an open cockpit and a fixed, tailskid undercarriage.[2] The upper wing was fitted with aerodynamically balanced ailerons and fuselage had an oval cross-section.[3] Design and developmentThe D.I had a protracted development through the course of 1917, with at least six development prototypes built before Rumpler settled on a final design in 1918 in time for the Idfliegs D-type competition at Adlershof.[2] Two 8D1s participated, powered by Mercedes D.III engines.[2] Another one participated in the follow-on competition in autumn, this time with a BMW engine.[2] Operational historyThe Idflieg approved the type for production and issued the designation D.I, but only a small number were produced; the war was practically over and none saw operational service.[2] Variants
