Schütte-Lanz D.VII

The Schütte‑Lanz D.VII was a single‑seat fighter prototype built in early 1918 by the German firm Schütte‑Lanz, better known for its air‑ship construction. Intended as a competitor to the successful Fokker D.VII, the D.VII incorporated a wooden monocoque fuselage covered with plywood, a design inherited from Schütte‑Lanz’s experience with lightweight structural techniques. Powered by a 180 hp Mercedes D.IIIa six‑cylinder engine, it featured a shoulder‑mounted, single‑bay biplane wing with slight stagger and a 7 m wingspan. The aircraft employed balanced ailerons on both upper and lower wings and a conventional tailplane with an enlarged rudder for improved maneuverability. Flight tests at the Idflieg test centre at Aldershof in May 1918 showed respectable climb rates and a top speed of about 190 km/h, but handling was deemed inferior to the Fokker, especially at high angles of attack. Consequently, only a few prototypes were built and the type never entered mass production. Although the D.VII did not affect the outcome of the war, it demonstrated Schütte‑Lanz’s attempt to transfer air‑ship construction expertise to fighter design and contributed to the evolution of streamlined wooden airframes in the post‑war period.
