Actually, after looking at the original drawing, shown in the first post of this thread,
I think, we just can be sure, that the designer showed, how to squeeze the engines and
transmissions into a single fuselage. The strange kind of tail wheel probably was adopted,
because a nose wheel wouldn't be possible due the engines in the nose and a conventional tail
wheel because of the pusher props. I don't think, that the planform of wing and tail surfaces
should be taken too seriously. And the cockpit isn't shown at all in the original drawing, to my
opinion, it just appears in that Jet & Prop drawing ! The artist put it at the place, he thought
to be suitable, maybe he didn't want to alter the shape of the fuselage.
But apart from the pure propulsion system, the drawing perhaps gives no hard informations about
an aircraft at all ?   
It takes a long time, before all mistakes are made ...

Something, that just came up to my mind :
Luigi Colani was born in 1928 in Berlin, so he was in the age of
about 17 in 1945. An aircraft, that seems to be just a teen agers
dream...., a designer, who later extensively used contra props,
and in tandem arrangements, too ....  and who advertised the "symbiosis
of fin and landing gear" for weight saving.... , and whose designs were
very often encumbered in a very similar way with a non-existent cockpit
view ....  and quite probably unflyable ?

That's the evidence : There was the "Volkssturm" in german design teams  !    ;D

One thing. Aircraft equipped with "Gruppenmotor" were quite common in WWII. Not the excessive flights of lunacy that saw the one dicussed here but any multi-row radial engine is a "Gruppenmotor". The one experimental one I would of loved to here was Wright Aero's Tornado. 42 Cylinders, 3 crankshfts, 7 layshafts. And they had plans to add two more sets of 14 cylinders for a 70 cylinder engine. Basically the 42 was 3 14 Cylinder engines set in tandem.

Weak Force Press has a bit of info on the Tornado.

Schnellstbomber V/max in 7km was 850km/h not 650km/h.

I just found this thread. I started looking at Unicraft's Dornier PP, and got curious about it this time, so started digging more, and found this thread.

If you wish, I wouldn't mind a look at this.

The PP I'd been wondering about off and on, and, like the Fw 190 with the turbine in the nose, didn't make a lot of sense, unless there was a proof of concept before this to prove the the idea.

I know, the Do335, but this beastie might've had a few different characteristics than the Pfeil.

Where did this come from?

Not the physical location, but the design itself, such as why non retractable mains, because wheels sufficient to support the aircraft can be made thin enough, yet still strong enough to support the aircraft, so what am I missing, unless non retracting gear was intended by the designer for other reasons.


I do know one thing, the Dornier might make a nice electric rc model, say around a meter span, unless you really want to impress yourself with a larger scale, perhaps 2 or 3 meters(for those who want to be ambitious).  ;)
