SCHUTTE-LANZ D I Germany
The Luftfahrzeugbau Schutte-Lanz produced, in 1915, what was subsequently claimed to be the first German single-seat biplane fighter. Designed by Dipl-Ing W Hillmann and Walter Stein, this, the D I, was a lightweight single-bay staggered biplane which had apparently found its inspiration in the Sopwith Tabloid. Of wooden construction throughout with fabric skinning, it was powered by an 80 hp Oberursel (Gnome) seven-cylinder rotary engine, but was rejected by the Idflieg on the grounds that the biplane afforded inferior pilot vision to the monoplane and was therefore unsuited for the single-seat fighter role. Hillmann and Stein introduced some redesign and installed a 100 hp Mercedes six-cylinder water-cooled engine to result in the D II, which, in the event, was never flown.
