They likely never existed as pre-1945 designs. By 1935, Fokker was abandoning its chronological sequence of 'F' designations in favour of designations based on seat numbers - beginning with the F.XXXVI (F.36) airliner. (Around the same time, the shift from Roman to Arabic numerals in Fokker marketing materials began in earnest.)I found those unknown Projects for Fokker,F.XXXIX,F.XXXXII & F.XXXXXVII,or F.39,
F.42 & F.57,does anyone hear about them ?.
Translation of the attached article via online translator and some corrections:....,but I think maybe it was anther concept ?.
That is odd. The R-1820 didn't exist when the Fokker F.X first flew. Perhaps Luchtvaartkennis is getting their Cyclones confused and meant the R-1750 (or even the earlier, 1654 cid Wright P-2 9-cylinder radial)?... there was a twin engined transport monoplane Project,appeared before F.X,powered by two Wright Cyclone 1820 engines ?,unknown designation for it ?.
A quibbling difference ... the 1922 sesquiplane project wasn't an "F.VIII transport airplane Project version". The built F.VIII didn't exist until 1927.... there was a Fokker F.VIII transport airplane Project version,but has a sesquiplane configuration, never built.
Okay. We know for sure that there was a 1922 F.VIII project and that Reinhold Platz launched into the built F.VIII design (as a trimotor) in 1926. No reason to assume that this designation couldn't have been recycled more than once ...No dear Apophenia,
I am sure it was called F.VIII,but the beginning of this designation was in 1924/25.
