O.Thetford, P.Gray German Aircraft of the First World War (Putnam)

Fokker V 8
  As may be seen this aircraft, built expressly on Fokker's instructions, utilised mostly V 6 components. It was not a success, and after only two short test hops it was scrapped. Engine was 120 h.p. Mercedes D II.

FOKKER V 8 Germany

  A decidedly bizarre single-seat fighter, the V 8 could be described both as a quintuplane and a tandem-wing aircraft. Powered by a 160 hp Mercedes D III engine, the V 8 had an unstaggered equi-span triplane wing arrangement mounted at the extreme nose and a biplane wing arrangement immediately aft of the pilot’s cockpit and approximately two-and-a-half times the wing chord behind the triplane structure. The top plane of each set of wings incorporated balanced ailerons, and a conventional tail assembly was provided at the end of an inordinately long fuselage, the CG being located between the two wing systems. Anthony Fokker made an abbreviated flight - barely more than a hop - in the V 8 in October 1917, some modifications subsequently being made before a further brief flight was made two weeks later, development then being abandoned. No data for this type were recorded.
