SNCASO / Sud-Ouest Aviation (SO) designations
« on: April 20, 2011, 03:33:59 am »
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

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).

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 ?

Great info, c460, thanks a lot! In case anyone wonders what the SO.P-1 (nicknamed « Ferblantine ») was, see the attachment below:

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.
