Udet-Flugzeugbau GmbH, München-Ramersdorf

Famous WWI fighter ace and stunt pilot Ernst Udet lent his name to this company but the aircraft were designed by Ing. Hans Henry Herrmann. Udet left the firm in the spring 1925. In 1926 financially-strapped Udet-Flugzeugbau was converted into a into a joint-stock company by the Bavarian government. This new company was rebranded as the Bayerische Flugzeugwerke (BFW).

Amazing work my dear,

and its projects is mentioned here.

http://www.gbv.de/dms/tib-ub-hannover/766124584.pdf
 
From Hesham´s PDF, the U.17 and the "Pinguin" are not the same. I believe two different Projects.

Well spotted Maveric! Another source has the same contents listing: "Udet U 17, 'Pinguin' und weitere Projekte" ... that comma making all the difference ;)

About the U 14 "Mexico" : Project for a nightfighter and recco two engined biplane (1926) It became later , in 1929 , the very similar BFW M 22 .

About the U 17 : Improved U 12 Flamingo . Two seater , Span 7,00 m ; Length 5,55 m .
 
Thanks Richard ... great stuff!

Am I correct in assuming that the U 17 was an unbuilt project?

I am trying to understand the U 2 , U 3 and U 4 designations .

At first , I think they are no two-seater , but single seater only .

http://histaviation.com/udet_u2.html

The U.2 is said to have a 35 hp Haacke engine flat twin , the U.3 and U.4 a 55hp Siemens radial .
(On the German register , NO U.3 , 9 X U.2 and one U.4 (Bäumer Aero))

For some sources Udet went to Argentina with an U.2 and a U.3 , for other with an U.2 and U.4 :

Capture d’écran 2021-11-16 à 15.26.15.png

Anyway , again an U2 with the Haacke and an U3 or U4 with a radial Siemens
Later , the Siemens one (race Nr 18 later 22) was modified , and identified as a U.4 :

http://histaviation.com/udet_u3.html

http://histaviation.com/udet_u4.html

I think
-Bruno Lange is right when he says "U 3 was a project only"
-Udet went in Argentina with an U2 and an U4 , later modified in Argentina when Udet returned in Germany

What do you think about that , my dear Watson ?
