SNCASO / Sud-Ouest Aviation (SO) designations

Stargazer · 20 April 2011

SNCASO (Société nationale des constructions aéronautiques du sud-ouest, or commonly, Sud-Ouest) was a French aircraft manufacturer, which originated on November 16, 1936, from the merger of the factories of Blériot of Suresnes, Bloch of Villacoublay and Courbevoie, SASO (Société Aéronautique du Sud-Ouest) of Bordeaux-Mérignac, UCA (Usine de Construction Aéronautique) of Bordeaux-Bègles, SAB (Société Aérienne Bordelaise) of Bordeaux-Bacalan and Lioré et Olivier of Rochefort. Additionally, SNCASO built a factory in Déols in 1936. SNCASO took over SNCAO's assets in 1941. On March 1, 1957, SNCASO merged with SNCASE (Société nationale de constructions aéronautiques du sud-est), to form Sud Aviation (Source: Wikipedia).

S.O.60A - low-wing, swept wing, 3 x Atar 101 (different layouts: two engines beneath the wings and one in the rear fuselage or three engines beneath the wing - ???)

S.O.60B – unswept low-wing, 4 x jet engines

A little bit OT:

Sud Ouest YHO-1 - US Army designation of S.O.1221 -> SOURCE: Flugzeuge von A bis Z volume III, page 355

Stargazer · 21 April 2011

boxkite said:
Sud Ouest YHO-1 - US Army designation of S.O.1221 -> SOURCE: Flugzeuge von A bis Z volume III, page 355

Yeah, correct. The full designation was YHO-1-DJ in an Army-only "HO-for observation helicopter" series ("DJ" being assigned as a company suffix for SNCASE here...).

For your information (and to REALLY be off-topic), this series had five more types besides the Djinn: YHO-2-HU (initially ordered as the XH-42) was the Hughes 269; YHO-3-BR was the Brantly B-2; YHO-4-BF was the Bell 206 prototype (quite different from the later 206A Jet Ranger); YHO-5-UH was the Hiller 1100; and YHO-6-HU was the Hughes 369 (the latter three evolved into the H-4, H-5 and H-6 of the new tri-service series in 1962).

The puzzling fact for the historian is that the "HO" series was a duplicate, as the prefix had already been used a little before by the Army for VTOL platforms: YHO-1-E for the Hiller 1031-A-1 (soon redesignated VZ-1-E) and YHO-2 for the De Lackner DH-4/-5 Aerocycle (soon redesignated as HZ-1).

The U.S. Army Djinn has been preserved, see picture below ("usaf" in the picture's name is incorrect since it was a purely Army project).

Hi all,
And, here,from "aviation-ancienne.fr"
the SO 50
Do you know more ?
Bye

c460 · 28 April 2013

In Le Fana no.213 on the SO.30, there are details on early SNCASO projects.
After the defeat in 1940, the design bureau was in Châteauroux and had these projects:
- SO.10 is an early name for the SO.P-1 glider by Servanty
- SO.20 is an experimental aircraft by Herbemont, abandoned very soon
- SO.30 by Parot is well known
- SO.50 is a four-engine cargo plane by Fandeux, abandoned in March 1941 when the bureau was transferred to Cannes
- SO.80 is a two-engine postal plane, later renamed SO.800, and not related to the former MB.800
On the Bloch MB.1020, the same article says that it was also called BA.1020 for Bordeaux Aéronautique, a company created by Bloch after the nationalization, and that it became the MD.1020R after the war. This model does not related to the SO.20, and I seriously wonder about the claim that the MB.1010/1020/1040 became SO.10/20/40 ?

You're welcome. Here is a scan of the article's relevant page. In the other thread on Bloch designations, I posted scans of the next two pages mentioning the MB.1020.

hesham · 28 April 2013

My dear C460,

did this article spoke about SNCASO SO.31 and SO.33 projects ?.

hesham said:

The fourth part of the article, in Le Fana no.216, mentions the SO.31 P and has a three-view of the SO.33. It is the scan posted by Toura in this thread on the SO.30.

To add further on the SNCASO designations, the 2nd part of the article, in Le Fana no.214, says that the early name of the SO.90 with tricycle gear was SO.90 B (later SO.93).

Thank you my dear C460,

in the dark.

c460 · 29 April 2013

There is more in Le Fana no.333, in an article about the Bloch 800 and SO.800 by MM. Ricco and Jung:
- SO.20 was an experimental trainer, that could be transformed into a fighter, abandoned in Nov. 1940
- SO.40, not in the July 1940 list, was wind tested in Oct. 1940, perhaps a lengthened version of the SO.30
- in the July 1940 list, SO.60 and 70 gaps were perhaps intentional, for evolutions of the SO.50
- SO.80 became SO.800 and is called MB.800 P in some documents ; the prototype was painted "Bloch 800 P" ; it was different but perhaps distantly related to the earlier MB.800 three-seat trainer (P3), created by the same designer Le Bihan
- SO.820 was a variant of the SO.800 wind tested in early 1941 ; the two-fin configuration was replaced by a single fin during the tests ; authorization was given to build the 820 but the prototype (with single fin) was finally called 800 P as said above
- SO.820 bis was another variant with widened rear fuselage
- SO.830 was wind tested in March 1941, no detail known
- SO.180 was a postal aircraft with two Renault 6Q and tricycle gear, related to the SO.93, date unknown

The info about the SO.91 comes from Flight magazine, 22 June 1944. It may be right, but we should be cautious because Flight authors did not have direct access to the occupied French industry.

hesham · 29 April 2013

My dear C460,

the Flight magazine described the SO.91 precisely,and may be they had
their sources.

hesham · 26 July 2013

Hi,

the SNCASO SO.20 was a two seat trainer based on Bloch MB.700.

c460 · 16 June 2014

In Le Trait d'Union no.245, special issue on the SO.90, Philippe Ricco gives the same description of early wartime projects SO.10, SO.20, SO.30, SO.50, SO.80 as in earlier Fana articles. Interestingly, he says that the gaps are explained by the will to leave space for future derivatives. This means that the SO.60, SO.70 came later, and maybe there was no SO.40 at all.

In the Docavia book about Nieuport, the authors say that SNCASO designations were divided in four series after several teams moved to Cannes in 1941, coming from the former SNCASO, SNCAN (ex-CAMS), SNCAC (ex-Farman), SNCAO (ex-Nieuport):
- series 10: heavy aircraft, Parot, Béziaud & Le Bihan design teams, supervised by Deplante
- series 1000: light aircraft, Pillon design team (former Nieuport / SNCAO)
- series 2000: seaplanes, Buret design team (former CAMS / SNCAN)
- series 3000: pressurized ("stratospheric") aircraft, Rocca design team (former Farman / SNCAC)

See also this document about the Cannes factory:
http://www.cannes-aero-patrimoine.net/pdf/pub/caspk_APADH__005_Jung_His_Cannes.pdf

In addition to those already listed, the Nieuport book shows a SO.1000 dive bomber project with two HS 12 Z, and an "E.1910", early configuration for the SO.1070.

Skyblazer, could you please update the initial list from the new information posted since 2013 ?

Hi,
There is a very good article about the Farfadet in Avions no.198.
Two examples of the SO.1310 were built, the first one with tip burners and the other with simpler compressed air jets.
The SO.1340 was a heavy compound helicopter project with four turbines, two of which were driving tractor propellors.
The SO.1350 was a heavy helicopter project, with four turbines.

The SO.3020 project was perhaps started as the NC.190 (source: Michel Borget in Le Fana no.389).

The SO.3000 to SO.3020 projects (and surely the SO.3030) were designed by an ex-Farman / SNCAC team led by Marcel Roca, based in Cannes under SNCASO administration from 1941 to 1944.

Hello Hesham

I have no record of a 2000 series design at all, not in SNCASO nor in CAMS or SNCAN. SNCAN has 2000 series models but none are seaplanes afaik. Any info or pics would be appreciated. I started looking at Les Ailes and Aerophile around 1946 but no luck so far. Usually these were 'press releases' and would be picked up by more than one av mag editor.

hesham · 25 February 2020

Hi Bazinga,

unfortunately a very small Info about them,the SO.2000 was a four engined civil transport flying boat Project,
the SO.2010 was a military derivative and SO.2011 was developed from Model-2010,and they were studied
in 1942.

Then there is some likelyhood that this indeed is a SO.2000 series (but unconfirmed) and that this design was revealed after France was liberated. I really have no other trace of a seaplane by SNCASO that comes close.

hesham · 28 February 2020

From Aviation magazine 1951,

here is an Info about SNCASO early aircraft series.

hesham · 29 February 2020

To know the early SNCASO series,it began from SO.80 as following;

SO.91,SO.92,SO.93,SO.94,SO.95 & SO.96 Corse were a variants,developed from SO.90
SO.100 probably not used "then started from Type-10";

SO.10-P1 was an early name for the SO.P-1 glider by Servanty,a single seat mid-wing with enclosed cabin
SO.10-P2 was a two-seat version,just a Project from SO.10
SO.10-P4 was a single-seat performance glider,two probably were built
SO.20 was an experimental trainer, that could be transformed into a fighter, abandoned in Nov. 1940

SO.31 & SO.32 were a developed versions of SO.30
SO.33 was a high-wing, single-fin variant,developed from SO.30,Project only
SO.40 was a developed version of SO.30,maybe a large one,Project only
