From "Die deutsche Luftrüstung 1933-45", Nowarra (not the best, but in this case probably a suitable source):

The Z-5 were modified Z-2 , fitted with inflatable buoyancy bodies in the bulge at the lefthand side of the nose
and in the rear of the engine nacelles, as well as an inflatable dinghy at the rear of the pilots seat. All other data
identical to the Z-2.

Well, the picture shows the Göppingen Gö 8 on a lorry trailer. So I presume, the author is writing about the proposed Do 214 flying boat.

No my dear Rolf,

the Do.214 had not a weight 170 ton ?.
 
The caption specifically says its a model of the 170 ton aircraft, so yes it is the 214.

How come,it had only 76 ton weight ?.
 
Maybe the difference between empty weight and MTOW should be remembered here ?
For the Dornier 214 empty weight is generally given as 76 ts, but maximum weight as
145 ts. But the latter is for the civil version, I think, for the military it may have been higher.
 
Is there any hint from an original source that proves the existence of design work of the P 238 shown in reply #2 and #5?

Hans Redemann who was highly accurate in his research presented this concept as the Do 435 in one of his articles for Flug Revue in the 1980s. As this was the time before speculative "internet art" and the time of still living Dornier designers there is a certain probability that it existed.

I posted a non-Dornier document from September 1944 concerning the fitment of radar systems to various German types, including the Do 435, here:
https://www.secretprojects.co.uk/forum/index.php/topic,25713.15.html Reply #25
And it shows a profile view of the Do 435 looking very much like the standard Do 335. All the other designs presented in the document clearly resemble the aircraft designs we know them to be (for example the forward swept wings on the Ju 287) so I'm inclined therefore to go with the description of the Do 435 from German Aircraft: New and Projected Types (longer wings, wider cockpit, but otherwise the same as the Do 335).
I know of no original source that proves the existence of the design work purporting to be the P 238 but it's possible that this was indeed the P 238. I don't think it was the Do 435 though.
 
Manfred Griehl in his book Do 335, 435, 635 also describes the Do 435 as a only slightly adapted version of the 335. A P 238 or a comparable design is not mentioned anywhere. However I still wonder where Hans Redemann got his source.

On p192-193 of Dornier Do 335, 435, 635, Griehl actually shows factory drawings of the P 238/1 and it's very clearly what's described as the Do 435 in the British January 1946 report - a side-by-side two-seater version of the Do 335. Griehl says it's the Do 435 too and he's obviously right.
So I think we can be reasonably confident that it's not the P 238/1 or the Do 435.
However, on p197 Griehl shows a 'rekonstruktion' of the Junkers Ju 435 which has a long fuselage a little bit like that shown in the drawings you mention, albeit without the blister canopy. This appears to essentially be a Ju 635 - which we know to have been real - without its second fuselage. It's not impossible that such a thing existed, but if it did, why call it the Do 435 or P 238?
The reality is we have an unnamed aircraft design of uncertain origin without any known primary source basis which resembles the Do 335. I suppose Redemann might have seen the drawing somewhere and guessed (wrongly) at its designation?
 
Yes. Designations aside, I assume Redemann had seen some sort of original source of this design. For aircrafts of this period his research and his three-view-drawings are still among the best.
 
In "Dornier 335" by Richard Smith , Eddie Creek , & Thomas Hitchcock (1983&1997) , the Do435 was "a modified version of the Do335 which was to be powered by the Jumo 222 , based upon project study P238 . It was similar to the Do335 , but incorporated a new pressurized cockpit and a long span wing with wooden outer panels."

Thank You! But this is not Do-217L that subtype existed : only two built with revised cockpit arrangement. it was derivate from Do-217K (1), some years ago i have seen an article maybe that was saved to my old computer (win XP) .. But I cannot found it again!


regards Karl
 
I had a look into the book:
Manfred Griehl, Dornier Do 217-317-417, Eine luftfahrtgeschichtliche Dokumentation, Motorbuch Verlag Stuttgart, 1. Auflage 1987.
In chapter "Dornier-Höhenkampfflugzeuge" on pages 173-174 he says:
Do 217 L was designed because Do P 183 did not reached the expectations (only 12.000 m instead of 14.000 m service ceiling).
This design, a project only, had an enlarged wing to 70 qm. There is no drawing.
The list of Do 217 aircraft production numbers on page 233 shows no Do 217 L.
