Strange, that the G.20 isn't mentioned in that blog, as it actually
was built and AFAIK finished after the war, but never test flown.

Sorry , I don't know more than "Le Monde" says ( see the link ) .
 
Yes, but the source book seems unavailable:

Maybe Google has scanned it but I don't know the procedure to check. Maybe dear Hesham knows?
 
The Gyroplane Automobile isn't mentioned in Cunys "Les Avions Breguet", but at least
it somewhat resembles the Breguet car type A2, which was electrically driven. Of course,
this maybe just accidentally and I'm not sure, if it was meant as a project at all, or just
to show the idea, that the amalgamation of car and aircraft could be beneficial.
Another Breguet Gyroplane, that can be found in the mentioned Docavia, too, is the G.34,
which was proposed in 1941. It was intended to carry about ten passengers and two crew,
powered by a GR 14M with 630 hp.

Many thanks, not even in Cunys "Avions Breguet" I could find a drawing of the G.10.
I remember having seen an artists impression of a helicopter very similar attacking a
submarine with gunfire. IIRC it was described as the G.20, but had a staggered cockpit,
so probably should show the G.10 .
 
In the Trait d'Union #172 that I will discuss in another topic is this sentence: (Bréguet Airplanes 1919-1945. Gyroplanes) We will not detail here the gyroplanes, directing for that to our special issue of Trait d'Union "René Dorand, 50 years of gyraviation", written by Pierre Boyer anf published in 1992. We will present only drawings illustrating the laboratory-gyroplane that would have been coded Br 314.
Someone may need this Dorand issue, no?

This artists impression was the site JC Carbonel, and a link to this page here:

A Bréguet project for a Trans-Atlantic helicopter with coaxial rotors drafted in 1936.

Some more documents showing the basic G.10 as well as the G.10B bomber version and the G.10S sanitary version.

Excuse me. In such drawings, what is the height of a person? And is there a size of the gyroplane itself?
 
How are these gyroplanes? They seem like helicopters to me
 
From Les Avions Français de 1944 à 1964 (Pierre Gaillard - Editions EPA, 1990):

'Société Française du Gyroplane G20 (1946)

Proche de la Société Breguet, et crée en 1938 par Vuillerme et Herbin, avec comme ingénieur en chef René Dorand, cette firme a travaillé sur plusieurs types d'hélicoptères jusqu'en 1945. Un exemple de G20, un hélicoptère de combat mû par 2 moteurs Renault 6Q de 240 ch entraînant deux rotors coaxiaux, a survécu à la guerre pour être présenté en 1946 (un autre avait été détruit en 1940). D'une silhouette très futuriste, pourvu d'un train escamotable, ce bel appareil, par ailleurs en retard sur le plan méchanique, n'a jamais quitté le sol, personne n'ayant osé mettre en route les deux rotors dangereusement proches l'un de l'autre.'

So strictly speaking, the G20 was not a Breguet product!

After all, what size was this helicopter? And what is generally known about the Breguet G.10 project?
 
As I guess,if that large Gyroplane was built,it could be also carry troops,military vehicles or small armored tank ?.
 
The images from post #3 (N.A.C.A. report) were part of "L'avenir de l'aviation", an article by Louis Breguet published in L'Aérophile in 1936. I'm attaching the entire article below.
