Junker Efo-21-3 Long Range Airliner Project

Post by John Withill » 26 Jan 2018 09:07

Hi Guys .

I'm trying to find out more about the above project . The only reference I have is from BLACK CROSS Vol 3 relating primarily to the Junkers Ju 90 ( p41 ) line diagram alongside that of the Arado E390 .
The Junkers EFo 21 looks very similar to the SM81 transport as developed for the Regia Aeronautica . I can't even find a Wiki page for the Junker aeroplane .
Has any one got any other reference on this ?
Regards .

The 1996 book Hugo Junkers, Pionier der Luftfahrt, seine Flugzeuge includes a three-view drawing of this design and describes it as having three coupled engines. However, I strongly don't think that the designation given in that book for this design was "EFo 21-3" because the EFo designation series was used by Junkers for jet aircraft design studies worked out in 1938-1939.

Why do people bother with Wiki? Because it's easy? The specialized aircraft questions need a specialist answer. The EFo 21-3 is not a project designation.. As can be seen in the illustration, there are rows of windows. This was a trans-atlantic passenger aircraft proposal.

There is a web site that covers Junkers aircraft. Here is more information:
