SNCASE / Sud-Est Aviation designation (SE)

[Bazinga]

Thank so much Hesham. I will remove the post. It only leads to confusion.

 

[Grey Havoc]

No need. Just add a note about the correct identification.

 

[Bazinga]

Could this be the SE X-250? Something of a design evolution of the SE-210 Caravelle. Ultimately the Caravelle Horizon was proposed but superseded by the Super Caravelle SST. She seems too small for the 30p SE X-205. 1952 AW&ST source.

SE-700 was a three-seat passenger autogyro,powered by one 330 hp Béarn 6D-07 engine
SE-700S was an improved version,maybe remained a Project,
SE-701 was a version,intended to carry 700 kg of load,powered by one 220 hp Renault 6Q-01 engine,also known
as SE-700A
SE-702 was a version,featured by a fuselage hull and a fixed front wheel,powered by one 330 hp Béarn 6D-07 engine,
also called SE-700B

@hesham I am just digging into this one as today is its maiden flight anniversary. But this has not much sense to me. Why presumably newer version has less powerful engine? The oldest book I have which mentions that autogyro id the one by mr Paul Lambermont from 1958 and it does not describe any variants, and the only engine data given is closer to what you wrote, but still different: Bearn 6 DO 5 developing 350 HP.

I came across some french on-line description which has more sense in regard of engine situation across its versions: https://aviationsmilitaires.net/v3/kb/aircraft/show/1567/sud-est-se-700#tab:tab-historique
And here is bit of it translated by google to english:

The Second World War delayed the program and the aircraft was assembled in Marignane during the Occupation. It could not make its maiden flight until May 25, 1945, in the hands of Stagenburg. It was then powered by a Renault 6Q-01 6-cylinder in line, providing 220 horsepower. The aircraft proved difficult to control and ended up crashing, without too much damage, in January 1946 (the 6th or the 21st depending on the source). Rather than repairing the first prototype, the SNCASE preferred to build a second, more elaborate prototype with a more powerful engine, the SE-700A or even SE-701. Its engine was a Béarn 6D-07 providing 330 horsepower, which was also originally planned for the program.

It seems that it is a copy-paste text from Wikipedia. As a source, among others, it gives a book: Gaillard, Pierre (1990). Les Avions Francais de 1944 à 1964. Paris: Éditions EPA. p. 33. ISBN 2-85120-350-9. Does someone has its electronic version?

I need to dive into Flight International archives - maybe there will be some more clues.

Accidentally came across some potentials information about "SE-210 Super Caravelle Atomique" the supposed nuclear power version.

I came across it thanks to @ToughSf Twiter account, and it leads to a Russian site called "aviadejavu." The site is pointing this design to JC Carbonel, which make the pciture looking legit to me.

The original 1958 dyeline for the conventional turbojet-powered “Super-Caravelle”, on which it was proposed to base a version fitted with turbojets powered by an onboard nuclear reactor.
This original three-view from the nuclear-powered Super-Caravelle brochure shows some of the proposed version’s salient features, including, RIGHT, the strengthened four-wheel bogie main undercarriage and the nuclear pile located aft of the stowed mainwheels, BELOW.
Detail drawings showing, from furthest right, front and side views of the beefed-up mainwheel units with four wheels, and the twin nosewheel arrangement. All of them were designed to offer extra strength on the basis that, on a nuclear-powered variant with little conventional fuel aboard, landing weights would be much the same as those for take-off.
Sud Aviation’s March 1958 brochure for a "Super-Caravelle" included an illustration for a nuclear-powered turbojet unit fitted to the tail powerplant mounting of a standard Caravelle, redrawn here by JUANITA FRANZI. The nuclear reactor or "pile" would replace the need for conventional fuel and provide power for the otherwise-conventional turbojet powerplant arrangement.
LEFT Sud provided illustrations for both direct-flow (open-circuit) and indirect-flow (closed-circuit) propulsion systems for the nuclear Super-Caravelle. This drawing shows the indirect method, which, it was thought, would emit less radiation and therefore require less protective armour, and was thus favoured for development.
RIGHT The drawing for the direct-flow (open-circuit) method, which would eject radioactive air in its exhaust, deemed unacceptable for obvious reasons! The entire concept would throw up problems that would be difficult to solve, and ultimately the nuclear power idea was discreetly dropped. Three views of the cockpit as provided in the brochure for the nuclear airliner; how its layout may have differed was not specified.

Hesham's lists are precious but I find it annoying that the designations are not written the way they should.
The use of a hyphen (-) was not common practice in French designations. The X series used a point, but the SE series didn't use any hyphen, dash or point. Here are a few designations I can add from my own lists:

SE 101 was a ground attack, not fighter, version of the LeO 50 (1952)
SE 104 long-range transatlantic flying boat project (9 tons of cargo + 70 passengers)
SE 112 no data
SE 200 ROCHAMBEAU (not AMPHITRITE, which was the LeO name for it)
SE 247 military derivative version of LeO H-47 (1945)
SE 1610 ground-to-ground missile (SS 20)
SE 1710 ground-to-ground missile (SS 20)
SE 1900/1910 were wheel carts, not "cars"
SE 3131 ALOUETTE GOUVERNEUR VIP version
SE 4241 variant of SE 4200
SE 4261 variant of SE 4200
SE 4350 variant of SE 4300 (150 ordered and 89 actually built)
SE 6000 projected supersonic interceptor

Also, the SE 700/701 autogyro design was called the ALOUETTE, before the name was applied to the later helicopters, and the SE 3140 was the ALOUETTE GOUVERNEUR, likely similar to the SE 3131.
There is apparently a conflict of designations over the SE 1500, which is also listed as a tourism glider.

 

[Stargazer]

The X.201 designation can also be found for a fighter seaplane project.
Also, the X.407 CASSEUR was a ground-to-ground ballistic missile (SSBT) project with a 100-km range (1956-57).

Many thanks,and I agree about these designations,

SE 112,200,247,1610,1710,1900,1910,3131,4241,4261 & 4350.

For SE 101,was a three-seat heavy fighter project in C.3 category as in my new book and also according to the book,SNACSE SE 100 Chasseur Lord Polyvalent,
and the only ground attack versions are SE 102 &103.

About SE 104,it was the same as X-104,and they called it SE X-104,but in briefly,
or shortly they referred to it as SE-104,in many source they did that.

To SE 6000,there is no confirm about it.

Also OK for SE 700 & 701,but what is the source about SE 1500 tourism glider ?.

SNCASE SE.1500 Series

Hello everyone, for my first suggestion I would like to tell you about the SNCASE SE 1500 and its derivatives for LeO 451.

SE 200 ROCHAMBEAU (not AMPHITRITE, which was the LeO name for it)

Also, the SE 700/701 autogyro design was called the ALOUETTE, before the name was applied to the later helicopters, and the SE 3140 was the ALOUETTE GOUVERNEUR, likely similar to the SE 3131.

Maybe some clarifications are needed: in January 1943, Vichy government decided to change all designations of planes produced for the French State, as you can see here:

Article 1 indicates that the use of any other names or designations for these types of materials is prohibited.

Then, the official list of new names was published end of March. The first letter "A" was assigned to SNCASE ("B" for SNCASO, "C" for Breguet, etc.). This the origin of the baptismal names "Amphitrite" for SE-200 (years after LeO H49) and "Alouette" as well, as you can see here:



The SE.3140 is another topic, but it is not the Gouverneur. SE.3140, nicknamed "Alouette-Turmo" was just an SE.3130 re-engined with a Turboméca Turmo II.

SE-4100 was a first French missile, Project only

It is not just a project.: the SE.4100 (former NC.3500) first launch took place the 29th September 1949.

SE-533 & SE-534 Mistral were unknown variants,maybe a Projects

I don't agree: there is no evidences that these designation were ever assigned to any project. You always suppose that if there is a hole in designation sequence, it means that the corresponding numbers were assigned to unknown project. I can confirm that in some cases, this is simply wrong. Sometimes, numbers were just reserved "in case of..." or simply jumped, but never used at the end. Some manufacturers also assign different meanings to the last digit, such as 0 for prototype, 1 for preseries or variants, 2 for series, 3 for foreign export, etc. It fully depends on the manufacturer and the time period.

So, as far as you don't have any trace of such projects, I suggest you to don't take initiative to fill the holes. By doing such, you introduce false information that will be repeated and create "legends".

SE-201 & SE-202 were unknown variants,maybe a Projects only

No evidences, I suggest you to remove those entries.

SE-205 & SE-206 were unknown Project versions

No evidence. I suggests you to remove those entries.

SE-208,SE-209,SE-210 & SE-211 were unknown Project versions

Idem, except for SE-210 which is well known: it was called "Caravelle".

SE-212 was a Project version of SE-200,powered by six Gnôme-Rhône 18R, wing area increase of 35 m° and 90 ton empty weight

Never heard about such project. Nevertheless, the SE-212 is also well known: it's the "Durandal". 2 prototypes built and flown. They derived from X-212 generic study.

SE-300 was a light transport autogyro Project,powered by one 350 hp Gnôme-Rhône engine

Never heard of it. Probably a typo for SE-700 version?
- SE-300 was the former Romano 111 T3 project.
- SE-300T was a flying boat project, tested in wind-tunnel at Toulouse during the War.
- SE-301: project, tested in wind-tunnel in March and April 1941.


Additional designations for your list:
- SE-116 "Voltigeur". 2 prototypes built (ex X-116A and X-116B)
- SE-117 "Voltigeur": 1 prototype built, ex SE-116-03
- SE-118 "Diplomate": project for 8-10 passenger transport version
- SE-119: project derived from SE-117.
- SE-216 "Fonceur": project derived from above family.

SE-1700 unknown Project,maybe a tourism glider,need confirm

No: the SE-1700 was a ground-to-ground missile, using flying-wing design. It was supposed to be launched from the SE-1900.
A variant using pulse-jet engine was called SE-1710.
In the same series you have the SE-1600 with additional vertical control surfaces, but you can also add its version SE-1610 using pulse-jet. All were planned for using SE-1900 launcher.

So, as far as you don't have any trace of such projects, I suggest you to don't take initiative to fill the holes. By doing such, you introduce false information that will be repeated and create "legends".

I have desperately tried to tell hesham the same thing for over 10 years now... Once something is written, it somehow acquires existence, and can lead others to confusion. I have seen that happens dozens of times.

SE-3001 was a flying model of the SE-3100
SE-3010 was unknown Project,need confirm

Wrong: the SE-3100 fying model is the SE-3101.
SE-3010: no evidence. Probably another typo. I suggest to remove it.

- From post war,SNCASE used a 300 series for helicopter ;-

X-300 to X-309 were unknown designs

X-300 was the initial study for HLU and HLO (Light Helicopter for Utility or Observation). It became the SE-340 "Gazelle".

For the other ones, I suggest to move them here: https://www.secretprojects.co.uk/forums/alternative-history-and-future-speculation.42/ or here: https://www.secretprojects.co.uk/forums/theoretical-fake-and-generic-projects.44/

SE 6000 projected supersonic interceptor

I never found any trace of such project. The SNCASE assigned each slice of 1000 to different design offices:
1000: Marignane (Poitou / Gross)
2000: Toulouse (Satre)
3000: La Courneuve (Renoux, then Mouille / Marchetti)
4000: Cannes (Marnay)
5000: La Courneuve (Jakimiuk)

As far as I know, there was no design office assigned to 6000 series.

Many thanks to you my dear Philippe,

but you mixed between two designations ?!,the early SE-200 series are for a developed versions or
projects from SE-200 Amphitrite, and as mentioned in some sources,from SE-200 up to SE-212,it
clearly mentioned after that,the series X-200s and when and concept became a prototype or entered
production,the company re-allocated or re-named it as SE-200s,such as X-210 became SE-210 and
X-212 became SE-212.

Never heard of it. Probably a typo for SE-700 version?
- SE-300 was the former Romano 111 T3 project.
- SE-300T was a flying boat project, tested in wind-tunnel at Toulouse during the War.
- SE-301: project, tested in wind-tunnel in March and April 1941.

What ?,in TU magazine and Retrohydro site,it's as I explained,please see the picture (11)

Wrong: the SE-3100 fying model is the SE-3101

That's also from a reliable source,but I don't remember it now,and may this was
the early designation,then changed into SE-3101.

X-300 was the initial study for HLU and HLO (Light Helicopter for Utility or Observation). It became the SE-340 "Gazelle".

Again ?,you mixed between early X-300 series from after the WWII which raised up to X-316,maybe more,
and the another series of X-200,which reached X-225,then raised as from X-230,240,250 ........,passing 300, up
to X-380.

Please have a good looking to replies # 86 and 100.

Hello,
I think you are mixing the designations, not me. The false idea to have an X-300 in sequence after X-230, 240, 250 etc. is a pure mistake from your side. You misundertand how the numbering was assigned by SNCASE.

Initially, the SNCASE X- series are assigned to design offices, as it was the case during the war for the slides of 1000 to 4000 for manufacturing: X-100 Marignane, X-200 Toulouse, X-300 La Courneuve helicopters, X-400 Cannes and X-500 for La Courneuve aircraft department (Jakimiuk joined the company after the war, and series 5000 was added, and then assigned to his team). Renoux did not use the X-3xx designation, neither Marchetti. This is only René Mouille who decided to use the X-xxx series for technological studies. Then he started with the HLU/HLO with 1/7 models, mainly to introduce the first composite material usage in helicopter structure.

Generally speaking, the X series was used by SNCASE after WW2 for generic studies or technological demontrators, not for projects and prototypes. When prototypes are purchased by public order, the designation is changed.
For example, the X-116 A and B "Fonceur" were ordered as SE-116-01 and 02 "Voltigeur". The SE-116-03 became SE-117. Their succesors were designated SE-118 and 119.There were never any X-117, 118, 119.
Other examples: X-210A to X-210G were studied by Pierre Satre, but when X-210G was selected, it became SE-210 "Caravelle". It's the same for X-212 generic proposals. When the Delta with mixed jet and rocket engine formula was selected, it became SE-212 "Durandal". Then, X-212 was discontinued and what you called X-212 "Durandal" is wrong, this name was assigned to SE-212, not X-212.


After the fusion between SNCASE and SNCASO, the company became Sud Aviation (SA-xxx), then SNIAS when they absorbed Nord-Aviation (AS-xxx). They continued using X-xxx series, but they opened the numbering to other sequences.

That's also from a reliable source,but I don't remember it now,and may this was
the early designation,then changed into SE-3101.

This is 100% false!
I have published the detailed history of SE-3101 helicopter in Le Fana de l'Aviation n° 323 in October 1996.
