The Albatros D.I was a German fighter aircraft used during World War I.
Although its operational career was short, it was the first of the Albatros D types which equipped the bulk of the German and Austrian fighter squadrons for the last two years of the war.
The D.I had a semi monocoque plywood fuselage, consisting of a single layered outer shell, supported by a minimal internal structure.
This was lighter and stronger than the fabric skinned box type fuselage then in common use, as well being easier to give an aerodynamically clean shape.
At the same time its panelled plywood skinning, done with mostly four-sided panels of thin plywood over the entire minimal fuselage structure, was less Labor intensive than a “true” monocoque structure.
The D.I was powered by either a 110 kW (150 hp) Benz Bz.III or a 120 kW (160 hp) Mercedes D.III six-cylinder water cooled inline engine.
The additional power of the Mercedes (Daimler) engine enabled twin fixed Spandau machine-guns to be fitted without any loss in performance.
The D.I had a relatively high wing loading for its time, and was not particularly manoeuvrable.
This was compensated by its superior speed and firepower and it quickly proved the best all-round fighter available.
