Fokker V.2

The Fokker V.2 and V.3 were prototype sesquiplane fighters developed from the Fokker V.1 but using liquid-cooled straight-six engines. Only one example of each was built, in 1917, as they were too heavy to offer any significant advantage over the Albatros D.III fighters already in service. Like the V.1, both had fuselages of circular cross section, which impeded the pilot's view downwards, and cantilever wings built from plywood, the outer part of the staggered upper wing being slightly swept back. The V.2's 120 kW Mercedes D.III piston engine and its radiator were fully cowled and the propeller had a spinner to reduce drag, and it kept the V.1's rotating upper portion of the vertical stabilizer acting as a rudder and fully moving horizontal stabilizers. The V.2 was 10 km/h faster than the V.1 but climbed more slowly. The V.3 differed in having the engine only partly enclosed, the radiator above the upper wing and a tail like that of the Albatros D.III.
