Flown for the first time in February 1918, the D.XI
departed from the traditional Albatros formula in certain
respects. Like its predecessors, it was of wooden construction with fabric-covered wings and plywood-covered
fuselage, but the unequal-span staggered
wings had inclined aerofoil-section I-struts braced from
their bases by pairs of diagonal struts which eliminated
the need for wire bracing. For the first time in an Albatros
fighter a rotary engine was employed, this being a
160hp Siemens-Halske Sh III, and the unusually large
propeller necessitated an exceptionally tall undercarriage.
Armament comprised the usual twin 7.92mm
machine guns, and two prototypes were built, the first
having a four-blade propeller and balanced parallel-chord
ailerons, and the second having a two-blade propeller
and unbalanced ailerons of inverse taper.
