I thought the Bloch MB.300 Pacifique was a pre-war trimotor airline prototype which was the competitor for the Dewoitine D.338. The MB.300 used the same wing as the MB.210 bomber and the MB.220 airliner, but with a wider 4 abreast seating fuselage for 30 passengers and an additional nose-mounted third engine......

No you're not! Anything that helps to clarify designations and versions has its place here I think.

I must be Stéphane, it looks like the topic is about Super Mystère model numbers (originally).

Well, that was until I cleaned up the mess and renamed it for ALL Bloch and Dassault model numbers... now you're RIGHT ON!!!

You're so cool......

After hesitating a while, I've decided to separate the Bloch and Dassault designations, as several numbers duplicate each other and also because the name change of the company's founder also corresponds to a change of decade and a real change in design philosophy.

Another modification I made was to remove the dot between the MB prefix and the design number. Sources are not all consistent on that point, but Bloch aircraft types are more often refered to as "Bloch 174" or "MB 174", for instance, than "MB-174" or "MB.174".

I have tried to give some details as much as I could in a one line format. Some aircraft are still missing their description but I'm working on it... Any additions/corrections are most welcome!

The Société des Avions Marcel Bloch was a French aircraft manufacturer of military and civilian aircraft, that further changed its name in Dassault Aviation, after the end of World War II. It was founded by Marcel Bloch (hence "MB" in the aircraft designations) who changed his name to Marcel Dassault (as in char d'assault, French for "assault tank") due to persecution of Jews under the Vichy French regime.

Hi;

MB.170(3) single engined light aircraft.

Needless to say: Great job Stephane!

From Dassault Passion Website: http://www.dassault-aviation.com/index.php?id=652

MB 90-93
Origins and context
To compete in the international Challenge of aeroplanes in 1932 Marcel Bloch develops the type 90 MB. First tourism by Marcel Bloch aircraft, it could open the road from the Alps to private pilots.
Find the 90 to 93 MB family sheets.

MB 90To compete in the international Challenge of aeroplanes in 1932 Marcel Bloch develops the type 90 MB. It is a two-seater tandem which the metal structure-high wing and the fuselage of steel tubes are burlapped. Two copies are produced, including the first registered F-AMBO, flies for the first time in June 1932. Two planes are engaged in the International Challenge. One must be piloted by Desmazières who had carried out a raid Paris-Madagascar with René Lefèvre in 1931. These machines are equipped with De Havilland Gipsy III of 105 ch resulting in a two-bladed wooden propeller engine. Even if it is ultimately not involved in the international challenge, the machine there is much interest because the speed and the ceiling, respectively announced 220 km/h and 6000 m, is likely to open the road from the Alps to the private pilot.

MB 91
Type 91 MB, equipped with a Pobjoy Niagara of 120 HP engine, is presented in 1933. The triangular vertical drift is replaced by a round drift. The machine do not steal, and is presented at the Salon of 1932 with a Renault engine.

MB 92
MB 92 "Grand Tourism" flies on September 9, 1932, piloted by Zacharie Heu. Fitted with a round derives from an engine Renault 4 Pei of 120 HP, one of the famous Stampe, resulting in a metal propeller, it has non-parallel poles and float landing gear of a single piece. Registered F-AMQT, it is purchased by a certain Clément.

MB 93
In July 1933, the 90-01 MB (F-AMB0), which belongs to Desmazières revole form 93 MB. Equipped of a round drift, divergent masts and triangular rear glass, he receives a De Havilland Gipsy Major I of 120 c. II engine knows no more success than its predecessors.

Thanks a lot, Retrofit! Unfortunately the automatic translation makes for a more than approximate text that is difficult to understand! Fortunately I'm French and I was able to make out what the original text meant...

The article in Le Fana no.213 on the SO.30 does mention the MB.1020 or BA.1020 (BA for Bordeaux Aéronautique, a company created by Marcel Bloch), later MD.1020 R, but as a potential competitor of the SO.30. (There is no mention of an MB.1030.)
The article briefly describes SO.10 and SO.20 projects which are unrelated to Bloch models, and says that the SO.80/SO.800 was not an evolution of the MB.800.

Great find my dear C460,


can you send this part from the article,please.

Of course, here are scans of the relevant pages. The Bloch is mentioned in the text only.

Thank you my dear C460.

More from Le Fana no.313, article on the MB.800 and SO.800 by MM. Ricco and Jung:
- MB.800 three-seat tandem trainer (military type P3), built and flown in Dec. 1940
- three-seat all-purpose variant (military type T3) planned for the second prototype of the MB.800
- Bloch 800B wind tested in Apr. 1939
- Bloch/SNCASO 810 and 810A wind tested in June 1939, unclear if MB or SO, no detail known
- MB.800 P, one of the names for the SO.800 postal aircraft, prototype built and flown in Dec. 1941

From Le Fana de l'aviation, Issue of April 2016, article about the MB.80/81, by Roland de Narbonne, page 34 :

MB 95. Project (1938) for the transformation of one air ambulance MB.81 in service in Lebanon, to a two seats plane.

Thank you my dear Deltafan,

and there is more info about it in TU 171.

Thanks Hesham.

Your article shows that the MB 95 was not only a project but was built, and that there was too a MB 41 (without known photo says the article) that was "foreshadowed" by the MB 95.

That's right my dear Deltafan,

but there is misprint,they meant MB.81,and as I think.

http://www.secretprojects.co.uk/forum/index.php/topic,1345.msg249927.html#msg249927

Thanks for the link with the drawing of the MB 95 Hesham

But I don't think that the TU speaks about the MB 81. Because MB 95 is a derivative of the MB 81, and (as said in the TU's article ) MB 41 is a "derivative" (foreshadow) of the MB 95.
The MB 41 is described as a "cabine fermée" (enclosed cockpit) in the TU's article. The MB 81 don't get an enclosed cockpit.

So

MB 80 --> MB 81 (one open seat and one enclosed bunk) --> MB 95 (two open seats) --> MB41 (x enclosed seats)

So weird my dear Deltafan,

but I think if there is a designation called MB.41,of course it will be MB.410,we know the
beginning of Bloch series is MB.60.

It's seems logical. There are a lot of examples where we can see that authors (including articles authors) made mistakes. Time will tell if there were exceptions in the Bloch designations

Hi,

From Aéro Journal, Issue of June 2017, article about the MB.80/81, by Philippe Ricco.

-It seems that your are right Hesham. The MB-41 did not exist. The article made a mistake. It was the MB-141 (not 410).

-Philippe Ricco writes too that there were at least 4 MB-81 modified as two seats liaison planes (n°2, 3, 6 and 7) in Syria-Lebanon, but he does not write that they were renamed MB-95. He writes that in France, a MB-81, no more saniary plane and with two seats but with the rear seat higher than the front seat, was built. And this plane is "sometimes" named MB-95.

Thank you my dear Deltafan.

At the beginning of the Cuny book Les chasseurs Dassault Ouragans, Mystères et Super-Mystères there are some new projects :

-Bordeaux Aéronautique BA 10 : fighter with 2000 to 3000 HP piston engine or jet engine (1944-45)
-Bordeaux Aéronautique BA 20 : unknown Aircraft (1944-45)
-MB 360 : six GR 18 R engines with 2200 HP each, transatlantic plane for 40 passengers or continental plane for 110 passengers, 63 to 68 T, travel speed 600 km/h (May 1945)
-MB 361 : derivative of the MB 360 with six PW with 3500 HP each, 70 T, travel speed 720 km/h (May 1945)

Very nice Info my dear Deltafan,

and that means there was MD.1010.

Fighter project ,see Skyblazer's reply#5 in this thread.

Thanks Hesham and lark.

It seems that the BA-10 could be (if it was) only a far derivative of the MB 1010/S.O.10.

-1200 hp for the MB 1010/S.O.10

-2000 - 3000 hp or jet for the BA-10

Hi all,

In searching for material on some of the early bloch planes I was wondering if someone knows if the french magazine "Aviation Magazine" Did a series of article on the Bloch company as it did on many others? Does someone maybe have scans of this? Thanks!

Filling in a few of the gaps ...

Stéphane's description of the MB 210 only matches the prototype. More a family resemblance than an actual MB 200 "derivative", the MB 210 had a fixed undercarriage and twin Gnome-Rhône 14s. Usually described as a second prototype, the MB 211 Verdun had a retractable undercarriage and HS 12Ys.

However, the production MB 210s had the MB 211's undercarriage and a number of detail changes to tailplane, wing sweep-back, and dorsal turret placement. Experimental variants were a 1936 Bloch conversion to 2 x HS 14HA radials; a Renault conversion to 2 x 1,000 hp Renault 14T-02/03 radials; and the MB 210H (Hydravion, a 1936 twin-float conversion of the MB 210 N°1 prototype (used at Saint-Raphaël for torpedo-dropping trials until at least November 1939).

Stéphane noted the 1937 order for 8 x MB 218 production versions of the MB 210H. That MB 218 order was cancelled because the aircraft had insufficient range. I find no mention of 'MB 213' to 'MB 217' designations.

I note too that Stéphane has the MB 720 as a "naval variant of MD.720". I have it as a naval derivative of the MB 700 light fighter designed by André Herbemont.

MB 700 - 1940 single-seat monoplane fighter prototype

On the MB 162, as designations, it would be more accurate to say that the MB 162-01 was the prototype and the MB 162 Bn5 the planned heavy bomber. As for derivatives, it is the 'VIP' MB 164 that is the fake. The MB 165 was quite real but predated the MB 162 bomber.

- MB 162.01: Redesigned, longer span, shorter fuselage, twin tails

MB 163 - (Project) MB 162 development, no details

MB 164 - (??) no details

MB 165 - (Project) Study of MB 162 Raid redesigned as bomber
- MB 165: Bomber based on orig. airframe, abandoned for MB 162 Bn5

Some notes and minor corrections on the Bloch MB 17x series ...

It would be more accurate to say that the MB 170-01 as a multi-purpose aircraft - hence the the convoluted designation MB 170 AB.2/A.3 (for Assaut Bombardement / Biplace/Armée Triplace). The MB 170-02, as you say, was completed as a fast bomber (MB 170 B.3). In both cases, the engines were 'handed' - Gnome-Rhône 14N-06 and 14N-07 (not just 14N-06). An order for 9 x MB 170 AB.2 fast bombers was cancelled and switched to 8 x MB 174 A.3/B.3 variants.

It would be interesting to know more about the MB 171, MB 172, and MB 173 projects. The entry on airwar.ru repeats William Green (1967), saying that they varied in crew size (two or three) and engine installation (without specifying type). But airwar.ru goes on to say "Most of these aircraft were heavy fighters" ... mention of which I haven't seen elsewhere.

The MB 174 A.3 was intended as a tactical recce aircraft (although it carried light bombs - up to 10 x 50 kg bombs). Again, the engines were 'handed' Gnome & Rhône 14N-48/49. One sub-type designation you could add is MB 174Z. This was MB 174 N°20 re-engined with two Hispano-Suiza 12Z V-12s fitted with Turbomeca PV.19B turbochargers. MB 174 N°53 was rebuilt with trailing edge air brakes as a MB 175T trials aircraft ... but I don't know if it ever received a special designation or suffix.

The MB 175 was more than just another production version of the MB 174. The MB 175 B.3 had redesigned wings (with a slightly broader chord and completely repositioned spars) to allow for a larger bomb bay than that of the MB 174. And, again, the engines were 'handed' Gnome-Rhône 14N-48/49 not just '49s.

Sub-type designations you could add are:
- MB 175A: (Project) Vichy bomber/torpedo bomber, only reached wooden mock-up stage
- MB 175B: (Project) Vichy heavy fighter, solid nose (4 x 20 mm, 4 x 7.5 mm offensive armament)
- MB 175B: 2 x 1,300 hp HS 12Z with turbochargers

The MB 176 N°1 prototype was actually a conversion of one of the pre-production MB 174s re-engined with two 1,050 hp P&W R-1830 SC3-G Twin Wasps. Production MB 176 B.3 models were based upon the revised MB 175 airframe. Total orders (most unrealized, obviously) were 403 x MB 176 B.3 with R-1830 SC3-G and 1,922 x MB 176 B.3 R-1830 S3C4-G

The MB 177 wasn't a prototype, it was a 1942 conversion programme. The Germans had robbed new MB 175s at Mérignac of their engines. So, surplus HS 12Y-31 V-12s were installed, creating the MB 177. These were 'gifted' to Vichy but only nine MB 177s were delivered to Déols (possibly because of intentional delaying tactics by Vichy).

The MB 178 prototype was a high-altitude variant. Power was provided by two Hispano-Suiza 12Y V-12s (probably HS 12Y-77s) fitted with Brown-Boveri turbochargers. The prototype was completed at Courbevoie and then transferred to Rechlin for Luftwaffe testing. I'm guessing that - other than those V-12 engines - the MB 178 would have been essentially the same as the unfinished Gnome-Rhône 14R-powered MB 179 project. -- http://www.warbirdphotographs.com/Avions4/MB178-4f.jpg

For the second application of the MB 140 designation, engine options (and roles) were a bit more complicated ...

MB 140 (II) - (Project) 4-engined medium bomber
- MB 140 (II): Derived from the MB 179 project
- MB 140 (II): 4 x engines (various types prop.)*
-- 4 x G-R 14N (followed by G-R 14R) or HS 12Zs
-- Bloch studies envisioned MB 140 B.3, A.3, & B.4 versions

Last one, and very minor ...

MB 500 (I): As you say, had the MB 500 been procured, it would likely be used mainly in the training role. However, it was built for the STAé's 1937 T3 triplace de travail requirement. No order was placed because officialdom realized that this role could be better filled by the Potez 63.16 T3 (derived from the 63.11, with all the attending commonality and training advantages).

MB 500 - 1938 twin-engined, 3-seat army co-operation a/c,* x 1
- MB 500 (I): 1938 T3 (triplace de travail) programme
- MB 500 (I): 2 x 300 hp Lorraine 9 Na Algol, span 15.75 m
-- * In a French context, with tactical reconnaissance also implied

Many thank to you my dear Apophenia,

and I will fix some of this stuff.

From Georges Messier's site;

a strange designation,MB.1020N,and I don't know if it was a navy version or what ?.

I suspect that this is an engine designation suffix indicating Gnome-Rhône 14N powerplants.

here is a Bloch MB.260.
