SNCAC (Centre) NC-820 twin-boom light transport project

[Caravellarella]

Dear Boys & Girls, here is a French "Secret Project" for you; the SNCAC Aérocentre NC.820 light transport. Note there are two engines driving contra-rotating propellors......

Most likely not "Secret", but very definitely a "Project"; dating from 1946......

The cutting is taken from the 29th December 1956 issue of Les Ailes......

Very nice one, Terry! Keep' em comin'!

Great find indeed, Terry!
Any clues about contenders ? Judging propulsion and capacity it would
have been in a class with the SNCASO SO.7010 Pegase.

 

[Caravellarella]

Sorry Jemiba, I don't know anything else; I'm immune to light aircraft ;D......

Carave, while you are at it, any more info on the SO-5000 Global Courier (turboprop antecedent of the SO-5100 Champagne) would be much appeciated....

 

[Caravellarella]

Dear Skybolt, how esoteric do you think I can get? And I'm not even French......

Thanks, this unknown twin-boomer is very interesting.
It seems this is a double engine driving a double propeller, less uncommon than the Matra R75 design (where 2 separate lateral engines drive a central propeller - or a central double propeller on the patent http://v3.espacenet.com/publicationDetails/mosaics?CC=GB&NR=605641&KC=&FT=E ).
