Dornier PP = Daimler Schnellstbomber
« on: April 08, 2008, 07:24:30 am »
Hi everybody

There are still some mysteries.....

At the Unicraft Page is a project called Dornier Push and Pull !!
It looks like a racing plane! I think it is not a Dornier Project,
because long time ago I have read a little article in the german magazin JET&PROP 4/03
There was a 3view of it and a little text about it, too.

“Daimler-Benz Bericht 1944“
“Untersuchung der Eindringtiefe eines 30 to-Bombers mit 5 to Bombenlast bei einer Maximalgeschwindigkeit von 600 km/h in 7 km Höhe“

The 3view shows the cockpit section in the nose (not behind the wings like the Unicraft )
And the bomb bay in the central with the Fuel tanks.
The 3view shows some good data, too.

Schnellstbomber Data
Triebwerk: DB-P83
               8 Gruppenmotoren zu je 2000 PS  
Leistung:   16000PS  
Maximalgeschwindigkeit: in 7km Höhe 850km/h
Abfluggewicht: 30 to
Bombenlast: 5 to
Eindringtiefe: 830 km
Spannweite: 11,32m
Länge: 13,76m

At the bottom of the 3view  was also a date
“ Untertürkheim, den 28.1.1944, Haug”

So, I hope this helps
The picture at the bottom of the page was shown in JET&PROP 1/92
http://www.geocities.com/unicraftmodels/germ/dopp/dopp.htm
Sorry,  I know this is not a real source but I have not found another Picture of it!!
What do you think about it!

Many greetings

In the 2 column article by Hans -Peter Dabrowski in Jet&Prop 4/03 -August-September 2003
a much more detailed 3-view is shown with a colour sideview by the author of the
article.
On the request by. Mr Dabrowski in the Daimler-Chrysler archives no more
information about the project could be produced.Even the name 'Haug' is not sure.
The illustrations on the Unicraft website are adaptions with much artistical
freedom of the original artwork in the Jet&Prop article.

Hi Lark and Moin1900,

nice info on that interesting project. Any chance to show us those two different drawings? All the best.

Hi everybody,

I have just received Lark`s excellent page taken from Jet&Prop. Many thanks to him. This project is fascinating, and much to do with Daimler-Benz`s "Heavy Fighter Project". Notice the annular radiator. I never heard about this DB P88 engine ( I also never knew about the use of the prefix "P" on DB), boasting 16000 Hp. By looking at that drawing I could assume it was made of "gruppenmotoren", existing engines coupled, apparently cylinder to cylinder bank ( very unusual, but the germans were great at odd solutions ), with each group sporting `till 2000 Hp.

Daimler-Benz "Gruppenmotor"

Hello fellas,

first of all I would like to thank Lark for the disclosure of this incredible "Secret Project". The bomber project was discussed some time ago, but I wonder if someone knows about this "beast" engine. It is a "gruppenmotor", made up of 8 2000hp engines . Specifications are present, so comments will be appreciated. What do you think?

hi Justo,

so nice to have you here. As usual, prime stuff. Any considerations on the specs?

If the reconstructions are correct in their placement and configuration of the cockpit... this plane would have been a freakin' *nightmare* to fly.

Hi,

indeed, it would be awkward to pilot. Perhaps some sort of periscopes would be needed, as in other designs, or a retractable cockpit. Nevertheless, it was purely conceptual. By viewing the drawing, what do you think on the engine?

what do you think on the engine?

A gearing nightmare. Multiple linked engines, long extension shafts, contra-rotating props... all kinds of ways this could fail catastrophically.
