OK I will send them without translate

Not sure how you expect hesham, an Egyptian, to correct an French to English Google Translation...

Time ago, I received these documents, showing an unknown French convertible study.

My dear Philippe,

the determining of the year is the best guide.

Quite a while ago, we had some proposals by Ivan Makhonine, which showed a very similar way to stow the rotors

You are fully right, it really looks compatible with Makhonine patent FR.966.032 (4/9/1948). A date is readable on the top of the 2nd drawing: December 1948.

Is it possible to raise a topic that was raised a long time ago?

Has there been any new information about the SNCAO CAO-810 project?

Unfortunately, I have already seen this. I'm interested in the blueprints, but apparently there aren't any.

Do I understand correctly that only these pictures remain from this project? I'm sorry, but the project looks really cool, but there are no drawings.

I just realized that I was very stupid. I already asked the same question last year. You told me that all the information can be found in your book.

It would be tempting to suggest that this D 55 might relate to the 1950 D 57 Phryganet. The problem is that the 1937 D 56 Lycène was a low-winged trainer project for Aviation populaire. So, why did the D 55 not appear until seven years later? Very odd.

Perhaps not so odd. There were quite a number of projects that were halted in 1939-40 because of the war, then restarted after it. It's not impossible that the whole D.5 sequence was considered at some point in the mid-thirties. Remember that the D.6, for instance, was a 1936 aircraft, but it's D.6.3 "Cri-Cri" development only occurred in 1948. Besides, the name "Phrygane" was not just used in 1949 for the D.21; it was already in use as early as 1933 for the D.1.

Hi,


here is the Salmson-Le Deville D4-S2 high-wing twin boom push-pull twin
engined light aircraft drawing from Ailes magazine;

From my dear Tophe.

Better share the entire article about both the D.4 and D.5 projects.
Please note that it was the D.4 S2, NOT "S4" as the file's title claims.
Also, it's DEVILLE, not "Le Deville". Paul Deville was the man behind all "Salmson" types between 1933 and 1950 (hence the "D." prefix). Originally his company was labeled "Avions-Deville à moteurs Salmson" but eventually everyone called them Salmson since that company no longer produced aircraft. It was part of the Compagnie Française d'Aviation (C.F.A.).

Considering the fact that Deville produced eight different types of aircraft and had at least five identified unbuilt projects, I really believe there should be a separate Paul Deville aircraft (Salmson D. series) topic.

... Also, it's DEVILLE, not "Le Deville"...
.

Quite. And that original article did make reference to "l'ingenieur Deville".
