The Fahlbusch machine had one pusher propeller circulating between the tandem wings.

TORK is right : it is not the Fahlbusch machine

Good luck

Well, another "Tandem-Eindecker" I have in my files - of which I am looking for pictures/drawings quite a while - is the machine built by Paul Neumann at Johannisthal.

Neumann let built the parts by the shipyard "Neptun" at Rummelsburg and built it up at Johannisthal in 1910. The apparatus was modified and tested until 1911, but never left the ground.

This is all I know.

Lange has it listed as "Dreiflächler" (three-winged) - though I have it as tandem monoplane. Maybe that comes from the front elevator...

Congratulation , you are right ... I am happy to bring you a picture of this "rara avis".This is the only one I have ever seen...
My source is "Deutsche Zeitschrift für Luftschiffahrt"
The description is in Lange and in the very interesting "Als die oldtimer flogen" (pp.44/5) by Günter Schmitt ,which inspired your answer , I guess .I don't know more ...

The #423 is for you

Cheers

Richard

Thanks Richard, for the picture!

You are probably right with the words by Günter Schmitt.

Are there further news within the "Deutsche Zeitschrift für Luftschiffahrt"?
About the engine or a characterisation of the motive concept?



And I can't resist to add a lingual remark.

I wouldn't use the term "Dreidecker" in that case.
It's simply because the word "Deck" in the meaning of level, is referring to wings (or other) placed above another.

To extend the term "Tandem", which is referring to things placed behind or next to each other, there are constructions like "Tridem" or "Triplet". Maybe "Triple-Eindecker" could be a German word for that. Otherwise I would say "Dreiflächler" or "Dreiflächner", what means three-winged machine as well.

But looking again at the picture, I belive the front wing is an elevator - so Tandem-Eindecker would fit better, in my eyes.

Cheers

Sorry , nothing more : only the photo and

" AUS JOHANNISTHAL : DER NEUMANNSCHE DREIDECKER MIT 2 VIERFLÜGELIGEN SCHRAUBEN "

But , you are certainly right : the front surface seems to be only a control surface .
