Société des Avions Marcel Bloch (MB) designations
« on: April 19, 2011, 06:24:29 am »
Known BLOCH and DASSAULT model numbers (list to be detailed later):

MB.300  Pacifique twin-engined bomber and navigation trainer (1948)

 

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......

OMG I'm so off-topic here  :o

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). :o

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

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. (source: Wikipedia)

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.

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
