The Ongoing Mystery Aircraft Thread Part Deux.

This type of design is tough to pin down because you see similar aircraft dating from the early teens to the late 1920's.
 
Knew I was going to guess wrong on the exact designation!


Something much younger.

Thanks Kevin - the round windows had me puzzled - reckoned it was an Avro 748, but couldn't find one with only 5 each side ! Looked too fat for a Gulfstream, but at the end of the day the windows did it. If only today's tubes had proper-sized windows, how much more pleasant flying would be.....

Here's a trimotor which had nice big windows, although not many !

Indeed, gX, the Avis, although I have it as BG.VI rather than BGV-1. But then 1924 was a long time ago.....
Unusual machine, 230hp motor up front and a couple of 100hop jobs alongside for good measure.
over to you - :very_drunk:
 
Well, I think the designation BGV-I which I took from Keimel (2003) who shows the same photo plus a 3-view drawing of the machine makes more sense than BG.VI.

As this was the first and only tri-motor built in Austria there were perhaps no BG.I through V before a no. VI.

Unfortunately, Keimel doesn’t give any explanation for BGV-I. Personally, I would propose Berg Großflugzeug Verkehr, No. 1 or something alike. The machine was built by the Avis Werke in Brunn am Gebirge near Vienna (Wien) and designed by Ob.-Ing. Julius von Berg. A-11 is its registration.

Placing such big radiators so close to the propellers is good for cooling efficiency but bad for propulsion. Perhaps they needed the two smaller extra engines to compensate for the losses of the primary one? :engel016:


Let's return to beaten paths! What about this “backseater”?

I have it as MAC-1 (NX2491) but it appears under the names Military Aircraft HM-1 or Miller HM-1, HM-2 as well.
