Unknown German Aircraft with DB600

[harrison987]

Hi guys,

I have an original blueprint, dated 1938. It features this aircraft. Engine is a DB600 with 2 bladed prop. Also has 1 MG firin through the prop hub. Number on the print shows the aicraft as possibly having a "19" as the suffix (8-19.00-02)

Overall, looks like a slight shorter Me109...







Any ideas on this?







TIA..

Mike

This is a project drawing of a planned Bf 109D with DB 600 later cancelled and changed to a B/C like version with Jumo 210Ga

Overall dimensions are ok.

According to factory dwg Bf 109A/B with Schwarz prop had 8700mm in length, Bf 109B with VDM prop - 8670 mm

The provided drawing has very close dimensions. Also note that rudder and fin dimensions exactly match 109B/C/D/E rudder and fin dimensions.

Hi!

Normally, I woud agree...but...

here is another more detailed shot...













As you can see, the wheel size is not correct for the main wheels...there are no trim wheels in the cockpit...fuel tank is under the pilot seat...battery is in the same location as an Me109G14/G10...and there are no MG's in the upper engine cowling...

hmmmmmm...

If genuine... it would be a Wiener Neudstadt 19, unfortunately WNF did not build 109 before the E-1 and certainly not in 1938.

Are you 100% it's genuine ?

"Institut für Aeromechanik und Flugtechnik T.H. Hannover"
T.H. means "Technische Hochschule" i.e. "Technical college". The date is not readable but I´d guess the later 30`s.
Maybe it´s a practise drawing of a student made at the Chair for aeromechanics and flight technics.

Hi all!

100% it is genuine. I have added extra photos.

Interesting...

The blueprint then does coincide with a WN19...but I have never heard of that aircraft. Is there any more information on it anywhere?

[RolandF]

Certainly it´s genuine from 1938, but no official project.
But according to the stamps it is the final papers of student Helmut F.Weitzmann to get his diploma at the Technische Hochschule Hannover. The circular stamp is from "Diplomprüfungsausschuss" ("examining board for the diploma"). The student assures having made the design all by himself (Selbstständige und eigenhändige Anfertigung versichert an Eidesstatt...).
Professor Dr.Ing. A.Pröll, who has signed the design, was chairman of the AKAFLIEG Hannover, the "Akademische Fliegergruppe Hannover"
"Wn" might be an abbreviation of "Weitzmann".

HI Roland!!

Interesting...

Aaaaaaahhhhhhh...was hoping it was official...

So is there such a thing as a Wn19? Closest I could find is a Wn16...

Or is this simply a "student concept"?

Hi Ole(?)!

The AKAFLIEGs ("Academic Flyer Groups") had been clubs attached to colleges (i.e. AKAFLIEG Berlin, AKAFLIEG München, AKAFLIEG Hannover etc.) and consisted from members of the colleges, i.e. students and professors, most of them being engineers.

The AKAFLIEGs designed mostly simply-to-build gliders. Founded mostly after WW1 when motor flight was forbidden in Germany the AKAFLIEGs were pressed into Nazi organisations after 1933. Some AKAs survived a certain time designing military planes like the B9 by AKAFLIEG Berlin.
That means the AKAs made their own designs, very much influenced by scientific research. Some produced as single examples, some finding their way to the RLM planners. Finally the AKAFLIEGs were incorporated - not few by force - into the Nationalsozialistischer Deutscher Studentenbund (NS German student´s association) or institutes like DVL (Deutsche Versuchsanstalt für Luftfahrt).

I don´t know, what´s Wn 16, but I´m sure newly engineer Weitzmann found his way into the German air industry.

Btw, many AKAFLIEGs were refounded after the war and are producing designs and advanced planes up to nowadays.

Hope this helps

It would be intersting if AKAFLIEG Hannover built their own planes

Could this be the same university today:
