Two unidentified models of French flying boat projects

[sienar]

Here is a pic of the D550/551 (not sure which) at Toulouse circa 1945. The two models (windtunnel?) on display are a mystery to me. I'm guessing dewoitine, but I have no idea of their origin.

 

[Stargazer]

The logo that appears on the corners of the sign placed before the stand is that of the Société Nationale de Constructions Aéronautiques du Sud-Est (SNCASE) or AEROSUDEST (the name that appears here), which was created in February 1937 from the merging of Potez, CAMS, Romano, SPCA and Lioré et Olivier.

Considering the period and the type of project, my guess would be a Potez-CAMS or maybe Lioré et Olivier lineage for these flying boats.

I tried to make them a little bigger :

 

[Jemiba]

Tail and nose remind me on the SE.200, but that flying boat was 6-engined and, although
quite large for its time, considerable smaller, than the mentioned 300 ts.
Perhaps pre-studies for the SE.1200 ? But even this design, at least in its known last iterations
was about half that weight. But a twin fuselage version of the 1200 could reach such dimensions.

My dear Richard;

What was those aircraft ?.

I tried to make them a little bigger :

My dear Richard;

Are those a Dewoitine designs ?.

 

[richard]

Sorry , I don't know more ...

 

[hesham]

Thank you my dear Richard,


I will figure out about them.

 

[Stargazer]

Are those a Dewoitine designs ?.

I think I made it pretty clear in my previous post that these projects were NOT associated with Dewoitine but with AEROSUDEST (which was soon to become SNCASE). Look at the pic again and check the logo on the board just in front of the table.

More large pictures.

It's another flying boat. But wing shape and vertical and horizontal tail stabilizer shape seems to be very similar to this lower one. ;D

As the photo is said to be from around 1945, I still would rather think of
pre-studies of the SE.1200. To my opinion, it wouldn't have made much
sense to present ideas about the older and already realised type there.

 

[hesham]

My dears,


there was also two missing designations,SE.900 and SE.1300,I know the SE.1300 was
a flying boat project,but no details,and for SE.900,it is a gap between SE.800 and
SE.1000.

Hi Jens! You mean this one?

[Jemiba]

Yes, sorry, had forgotten to add the link.
Those models somewhat remind me of similar designs from Breguet.

Dimensions and weight of flying boat projects were still rising after WW II !

 

[hesham]

May be I can solve this mystery,


they are no sign for them in,Les Avions Dewoitine,Les Avions Potez and Liore et Olivier
books,also Potez-CAMS,and no trace from Romano and SPCA,I think they are Hamel
heavy transatlantic flying boat projects,and they are two designs for his 300 ton
aircraft,he worked from 1935 up to 1945 as TU magazine,please see also;

[Jemiba]

I'm afraid I cannot see a connection to G. R. Hamel. Those two designs clearly were
made by Aerosudest (Later SNCASE) as the panel clearly shows and at least the single
fuselage type shows a marked resemblance to the SE.200. And the Hamel designs actually
look older, I would think of the '30s. Maybe Monsieur Hamel was working for Aerosudest then,
but I couldn't find a mention in those pages. If I just overlooked it (they are quite hard to
read), please tell me.

 

[hesham]

My dear Jemiba,


even when we talk about Sud Est and its divisions,no sign for them at all,even
with the books; Les Avions de combat I & II,and may be Hamel worked for the
Sud Est,and his activities was still up to 1943,please see L'Aerophile May and
November 1943.

Hi,

maybe one of them was SNCASE SE-014 Project ?.

Do you remember the source ?.

 

[hesham]

I tried to make them a little bigger :

I think the right one was SNCASE SE.200/4 ?.

there is no image but look in the 1930 its the dewoitine HD46 4engined flying boat

What,

of course it was not it at all,they were from 1945;and hereis HD-46;

O: ty a lot for the dewoitine design i was searching for a castelo flying boat design

Such as what ?,I can't find any reference to those two heavy flying boat four engines in the site ?!.

theres the HD.46 and the HD.700 these are the two four engined flying boats mentioned in the site in the dewoitine production page

there are no images btw

That's not true,the HD.46 was from 1930 and HD.700 was from 1934,and those
designs were appeared in 1945 ?!,and they were not related to these concepts
at all.

i think the plans were secret before
