SCHUTTE-LANZ Dr I Germany
The operational debut of the Sopwith triplane on the Western Front in the spring of 1917 aroused considerable interest in this configuration within the Idflieg which immediately encouraged the development of conceptually similar fighters by the German industry. Among single-seat fighter triplanes submitted as a resuit was the Dr I proffered by the Luftfahrzeugbau Schutte-Lanz. Powered by a 160 hp Mercedes D III six-cylinder inline water-cooled engine and carrying the then standard armament of twin 7,9-mm LMG 08/15 machine guns, the Dr I mated the fuselage and vertical tail surfaces of the D III biplane with a triplane wing cellule. The arrangement of the wings was unusual in that forward stagger was applied to the centre plane, presumably in an attempt to improve view. The Dr I participated in the second D-type contest (27 May - 28 June 1918).
