Does anyone have any information on the development of the Volksflugzeug (people's airplane) Siebel Si.202 Hummel ("Bumble-bee")?  Perhaps alternatives that were considered before the design was finalized and produced?  Below is the original prototype with a little French Salmson nine-cylinder radial, the production models all had four-cylinder inlines.  Thanks!

From Nowarra "Die deutsche Luftrüstung 1933 - 45":
Designed by Friedrich Fechner and Fritz Siebel in 1938 as a cheap, robust and easy to fly twin seat
sports aircraft to allow wide sections of the population to fly. Design points were use of a low powered
engine and side-by-side seating in an enclosed cockpit to make the type suitable as a trainer (? most training
aircraft of this time had tandem seating, I think
)
Three versions were built:

Si 202A: The basic type with squared wing and tail to allow for easy repair. Engine was an Salmson 7 AD radial of 45 hp

Si 202B: Basically the same type, but with  a Zündapp inline engine of 50 hp.
(The attached photo is labelled as "Si 202 B", but the shape of the rudder contradicts this, probably a C version
drawing is from the mentioned book)


Si 202C: Fitted with rounded wingtips and balanced rudders, engine was a Hirth 515 inline engine of 60 hp. A second tank
was installed for an increased range (drawing see Maverics post)

No information about early or alternative designs, sorry. But as it was intended from the start as a kind of training aircraft,
it seems to be plausible, that it should resemble the "standard" aircraft of this time, that means, low wing monoplane, I think.

We can speak here about Siebel prototypes and projects,

there was a report in 1945,explained that,the Siebel company did a further development
of DFS 346 supersonic experimental aircraft ?.

Many works done in USSR;

there have been some changes in the design of the machine,have improved the sealing of the fuselage,
landing fences at the ends of the wing.

Obviously Siebel actually made a proposal to the tender for what became known as the "Volksjäger",
but still yet no data have surfaced, not to mention drawings.
This proposal is mentioned here on page 61
https://www.google.de/url?sa=t&rct=j&q=&esrc=s&source=web&cd=11&cad=rja&uact=8&ved=0ahUKEwiykp693ubYAhVBCewKHdKbAWMQFghSMAo&url=http%3A%2F%2Fothes.univie.ac.at%2F29317%2F1%2F2013-08-08_0548954.pdf&usg=AOvVaw0aF1dxapuZL5NLKDoLELwj  ,

a quite interesting read, though to my opinion somewhat biased. After all, the data given should be relatively
reliable, as it is a from a master thesis. And if the examining board took its task seriously, the used sources
shouldn't included totally useless ones .

It's because the Siebel Flugzeugwerke together with Messerschmitt's and Fieseler's design offices soon back out the Volksjäger Program,
when they recognized that terms of the RLM specifications of 10 September 1944 are impossible to fulfil for them.
By the way  ...
http://www.histaviation.com/siebel_si_202.html some more informations about Siebel Si 202.
Christianity will go. It will vanish and shrink.
I needn't argue with that ; I'm right and I will be proved right.
I don't know which will go first, Rock'n'Roll or christianity ?

Finally I get the source.
 
"X-planes - German Luftwaffe Prototypes 1930-1945" by Manfred Griehl, Casemate 2012

From Ailes 7/1948,

there was a sketch for jet version of DFS.346,did by Siebel in USSR,as mentioned in many
reliable sources,of course the drawing was just a hypothetically concept,by the only fact
we know,there was a development to this experimental aircraft in Russian,and unfortunately
with no details ?.
