Years ago I had a picture of a Fokker D-7 with no lower wing. The caption stated that , when Fokker and Platz were thinking of building the E-V, they did a feasibility test with this craft, and it flew surprisingly well. Has anyone got a copy of this pic?

R Pope:
I don't think I have ever seen this photograph. without the lower wing, the CG would be too far forward and would have made the machine very tail heavy. Reinhold Platz was an expert welder, he did not have anything to do with the design of any Fokker aircraft. This is a phony story put out by A.R.Weyl who wanted to denigrate Anthony Fokker, Weyl had an intense dislike of Fokker. Platz was not a engineer, he was an expert welder. At some point Fokker put Platz in the experimental testing department. Platz had nothing to do with any aircraft design. Blue skies, Dan-San |

It waas not the V29. in the caption it was pointed out that the bottom wing mounts were visible, and under the top wing you could see the interplane strut mounts . Also the wing was obviously a fabric-covered D7 piece. It would have been an easy matter to modify the cabane to shift the center of lift rearward. That'd be "excellent welder" Platz's job.

Why a high winged monoplane ? Wouldn't the aircraft's wingfs be stronger if mounted low and direct to the fuselage rather than above the fuselage ?

Two things occur:
-Pilot visibility -different aerobatic characteristics, given same or similar proportions. (probably wrong on the second one)

Parasol monoplanes, in the WW1 time frame with the smaller, lighter construction than in WWII, would not "float" on landing like a low wing, and the small amount of wing center section that would be blanked by the fuselage in a low wing allowed a significant increase in wing area for the span. This would give an increased rate of climb and ceiling, which was deemed more important than all-out speed.The pendulum effect of the high wing made for lateral stability without dihedral, making a one-piece wing spar easier to build. Remember, the preferred tactic was to dive on an enemy, so downward visibility was paramount.
