In 1924 the Société Dyle et Bacalan of Bordeaux established an aviation branch. On 25 July 1929 it became known as the Société Aérienne Bordelaise (S.A.B.), a subsidiary of Nieuport.
Eventually it became part of Société Aéronautique du Sud-Ouest on 12 January 1935.

Do you have the special issue of "Le Trait d'Union" dedicated to Dyle et Bacalan? I have it somewhere...
The Trait d'Union cover of Dyle and Bacalan is not an article but a full 90-pages booklet (special issue dedicated to this subject).
I guess anyone may order it (20Euros+P&P) at http://www.aerostories.org/~aerobiblio/article290.html
or ask Google to translate this French page from a search typing: BFAB Bacalan
Cheers,
Tophe
PS. BFAB is Branche Française d'Air Britain (Air-Britain French part)

Being a member of the BFAB, I may try to reach the director Jean Delmas to ask what happens. Sorry. By mail, as I think he has no E-mail.

Coming back from holydays, Mr Delmas answered:
- only cheques/checks (in Euros, to "BFAB") from banques located in France are accepted by the Trait d'Union
- or Euros bank-notes/bills inside a separated enveloppe are accepted, this may be illegal but has been done sometimes
Mr Delmas said that many foreign (not-French) people do order and receive. I wish you good luck... (otherwise, maybe I could order for you from France, but I don't know how to be paid back)

while searching for something else,(this:-http://www.secretprojects.co.uk/forum/index.php/topic,5188.msg41169.html#msg41169 ),
i came across this, Dyle et Bacalan DB 10Bn4.

Dyle et Bacalan DB10 Bn4 experimental twin engined four seat night bomber of 1925.
this aircraft used the 'lifting fuselage' concept, which apparently was developed independently of Burnelli in the USA.
the DB 10 was of all-metal construction,and powered by two Gnome-Rhone Jupiter radials.
pilot and co-pilot occupied separate tandem cockpits, and a gunner's position was situated over the central wing leading edge.
this was equipped with a scarff ring mounting twin lewis guns. the navigator'scompartment was located in the wing centre section.
a bombload of 2,866lbs (1300kg) could be carried internally.

performance:-max speed 118mph (190 kph), max cruise 107mph (173kph) at 13,125ft (4000m), service ceiling 18,045ft (5500m).

empty weight 6,944 lb (3150 kg), loaded weight 12,346 lb (5600 kg)

span 82' 1/4" (25 m), length 44' 7" (13.6 m), height 12' 5" (3.8 m), wing area 1,001.04 sq ft (93m2).

source:- Air International, August 1976, page 94

cheers,
Robin.

In the wonderful special issue of Trait d'Union magazine "L'aéronautique à Bacalan" (published in 2002, 94 pages devoted to Dyle & Bacalan and Bordelaise) is the "Avion Dyle et Bacalan" model A tested at Eiffel Lab, forefather of the DB-1 then DB-10, with a Burnelli-like fuselage, 1924.

With pictures are of course presented the Dyle & Bacalan DB-10, DB-20, DB-70, DB-80, DB-81, AB-20, AB-21, AB-22, AB-80, LH-70 but without picture are also mentioned unbuilt projects:
- DB-90 and AB-15 of 1929 (in the family of DB-70) wrongly named DB-71 by journalists of that time
- 28-tons 4,000hp living wing.

Dear Boys and Girls, because I posted this aircraft in the wrong topic; here is a small article in French on the Société Aérienne Bordelaise AB.80 prototype. It isn't "secret" and it isn't a "project", but shows an interesting mix of typical Dyle & Bacalan/Bordelaise construction with a cantilever wing. I cannot work out which other French multi-purpose bomber/reconnaissance types are its contemporaries and which were designed to meet the same requirement......

The article comes from the 15th April 1969 issue of Aviation Magazine International......

French designers during 30's relized sometimes elegant design but more often ugliest ones ever.... ;D

Luckily it came Marcel Dassault with its Mirages during '60s.

The "Société Aérienne Bordelaise" was the new name of the "Dyle & Bacalan" company specialized in railway and naval construction. that's help... ;D

Yep, but way back when Dassault was still known by his real name Marcel Bloch, he produced some pretty horrendous designs too... ;D

Of course, probably he spent the second half of his life making trasure of what did in the first half.
Anyway he was also quoted for this "if it is beauty will fly well"....

Exactly. You can tell that he learned the lesson the hard way. Experience made him create beautiful aircraft that flew wonderfully and still do.

A little less "normal" perhaps (though quite elegant in its own way), the 14-ton, twin-fuselage D.B.70:

Quite obviously, the D.B.70 led to the A.B.20 and A.B.21... First two photos are from another forum topic:

Hi,


in the 1928 program for twin engined torpedo bomber competition,the main contenders
were;


Latecoere L-290 & L-440,Besson MB-30,SPCA-20,LeO H-16 & H-257,Nieuport NiD-50,CAMS-52,

Hi Hesham,

The Fana de l'aviation from May 2016 has a few lines about the BA 30.

BA 30 is the first name of the future Dassault MD 3-- Flamant séries

Bordeaux Aeronautique is not linked with the Société aérienne bordelaise (SAB) that built the Dyle et Bacalan planes.

After the nationalization of the Bloch factories (1936), Marcel Bloch founded the SAAMB (Société anonyme des avions Marcel Bloch) and other more little societies. Among these societies was Bordeaux Aéronautique.

Bordeaux Aéronautique built part of the reco / light bomber Bloch/SNCASO* 174/175 and had an office engineering. This office engineering studied the BA.30 project.

After WW2 Marcel Bloch changed his name and SAAMB became GAMD (Générale aéronautique Marcel Dassault). It was the end of Bordeaux Aéronautique too.
The BA.30 project became the modified MD.30 project. The MD.30 became the MD.303 plane. And the MD 303 plane gave the Flamand séries (311, 312 and 315) with around 320 planes.

*SNCASO (Société de construction aéronautique du Sud-Ouest) got part of Marcel Bloch factories, among them the factories that built later the MB.174 and 175.
