Fokker D.VI

File:Fokker V.13 (2161 026110).jpg

In late 1917, Fokker-Flugzeugwerke built two small biplane prototypes designated V.13. These aircraft combined a set of scaled-down D.VII wings with a fuselage and empennage closely mirroring those of the earlier Dr.I.Gray and Thetford 1962, p. 103. The first prototype utilized an 82 kW (110 hp) Oberursel Ur.II rotary engine, while the second featured a 119 kW (160 hp) Siemens-Halske Sh.III bi-rotary engine.Weyl 1965, p. 262.

Fokker submitted both prototypes at the Adlershof fighter trials in late January 1918.Weyl 1965, p. 264. At that time, Fokker reengined the first prototype with the 108 kW (145 hp) Oberursel Ur.III.Weyl 1965, p. 264. Pilots found the V.13s to be maneuverable and easy to fly.Weyl 1965, p. 269. Idflieg issued a production contract after the V.13s were ultimately judged to be the best rotary powered entries of the competition.Weyl 1965, p. 269.

The new aircraft, designated D.VI, passed its Typenprüfung (official type test) on 15 March 1918.Weyl 1965, p. 271. The production aircraft utilized the Oberursel Ur.II, which was the only readily available German rotary engine. Idflieg authorized low level production pending availability of the more powerful Goebel Goe.III.Weyl 1965, p. 271. Deliveries commenced in April and ceased in August, after only 59 aircraft had been completed.Gray and Thetford 1962, p. 102. Seven aircraft were delivered to the Austro-Hungarian Air Service (Luftfahrtruppen).

In service, the D.VI was hampered by the low power of the Oberursel Ur.II.Weyl 1965, p. 271. Moreover, the lack of castor oil and the poor quality of "Voltol," an ersatz lubricant, severely reduced engine life and reliability. The D.VI remained in frontline service until September 1918, and continued to serve in training and home defense units until the Armistice.
