hi all

 

[Stargazer]

Here is a list of all known Potez designations. If I missed something out or made a mistake, please let me know so I can update the list accordingly. Thanks to AM for providing a lot of the information therein.


Société d'études aéronautiques (SEA)

Created in 1916 by Henry Potez, Marcel Bloch and R. Lévy-Finger, with Louis Coroller as main designer.

SEA I observation two-seater

SEA II two-seat reconnaissance and fighter aircraft that did not fly

SEA III three-seat reconnaissance aircraft which did not fly

SEA IV biplane two-seat fighter
SEA IV C2 observation two-seater (also Potez IV reconnaissance two-seater)

SEA V


Aéroplanes Henry Potez

Founded by Henry Potez in Aubervilliers in 1919. The company moves to Levallois in 1921. Louis Coroller still designs most aircraft. A new factory opens in Meaulte in 1925. Another one eventually opens in Berre. The company is eventually absorbed by SNCAN (later Nord Aviation) in 1936 but the designs keep the name Potez.

Hi,

P.68 twin-engined low-mid-wing project.
P.703 & P.705 developed from 702
P.90 high speed light transport aircraft,based on 75
P.92 single seat twin engined jet strike and close-support project and the engines was mounted above the rear of the fuselage in a new shape,it was designed to compete Breguet Br.121.

 

[hesham]

My dear Stargazer,

the Potez-CAMS 220 & Potez-CAMS 230 don't belong to CAMS,it belongs to
ANF-Les Mureaux after Potez took over it,and you can say Potez-ANF-Les
Mureaux 220 and Potez-ANF-Les Mureaux 230;

hi all

 

[Apophenia]

A bit more detail on Potez 63 variant designations ...

The Potez 63 was designed to meet the Service technique aéronautique (STAé) Programme Technique C3 (Triplace de Chasse) requirement of Oct 1934. Work began (led by engineers Coroller and Delaruelle) in April 1935 with a prototype flying one year later. A contract was received in May 1937 for 10 examples in fighter, night fighter, conversion trainer, light bomber, army co-operation, and attack aircraft configurations.

Potez 63 series designations followed the French pattern of applying numbers to the end of the type designation to indicate major design changes. In some cases, those designation changes were the result of different engine types being employed. More often, designation changes indicated the application of different mission-specific equipment.

Armée de l'Air (AdA) designations built on the manufacturer's form. To that maker's designation was added letters signifying role and numbers for crew -- so a Potez 630 C3 was of the first 63 series variant and a Triplace de Chasse (or three-seat fighter). Ada role abbreviations applied to Potez 63 series variants were as follows:

A --- Armée (Army co-operation)
AB -- Assaut-Bombardement (Attack Bomber)
B --- Bombardement (Bomber)
Bp -- Bombardement en Piqué (Divebomber)
C --- Chasse (Fighter)
CN -- Chasse de Nuit (Night Fighter)
Ins - Instruction (Conversion trainer)
T --- Travail (General Purpose)

No 'P' for Postale designation seems to have been applied to two Potez 63s modified as air mail carriers and transfered to Société Anonyme Air Bleu in late 1938. These aircraft are usually listed as 630s (although Golden Years lists F-ARIR as Potez 637 c/n 21 - possibly a conversion of Potez 630 c/n 1).

Potez appended country names to export variants, eg: Potez 633 Grec, 633 Roumain, and 63 (or 633) Franco-Roumain (for airframes begun for the AdA but completed for FARR). But I've seen no reference to a 'Potez 631 Finnois'. This style was also applied to at least two demonstrator aircraft -- the Potez 630 Suisse. Yet no such labels seem to have been added to the Yugoslav 630 demonstrator (F-AREY).

The planned Czech-licensed Potez 631 received a distinct type designation - Potez 636. However, there seems to be no record of a separate designation for planned licensed Mitsubishi 631 (to Spec 13-shi for a 3-seat, twin-engine fighter-bomber). Possibly the 'missing' Potez 638 designation was applied to this proposed Japanese variant?

http://www.secretprojects.co.uk/forum/index.php/topic,12142.msg118569.html#msg118569

There is some confusion over prototype Potez 63 designations. Was the first prototype Potez 63.01 simply redesignated Potez 630.01 (after one of its many engine changes, perhaps)? Or, as some sources claim, was the Potez 630.01 a second prototype? Can anyone clear this up?

Further confusion surrounds the Potez 631 Ins and Potez 634 dual-control trainers. Did the ten Potez 631 Ins (taken from early Potez 631 production) obviate the need for the Potez 634? Or are, as some source claim, the Potez 631 Ins and Potez 634 one and the same?

and I want to add;


P.672 was developed from P.671,as special acrobatic aircraft project,powered by two
1000 hp Hispano-Suiza 12 Y 21 engines.

 

[Apophenia]

Thanks for that Hesham. I'd never even heard of the Potez 672!

 

[hesham]

Hi,

Potez P-80 & P-82 were a three engined transport airplane Projects,no more details
are known ?.

 

[hesham]

[hesham]

Hi,

Potez P-80 & P-82 were a three engined transport airplane Projects,no more details
are known ?.

Sorry for this mistake,they were powered by two turboprop engines for each design,and
not three.

 

[hesham]

By the way;

SEA.V was a single seat fighter monoplane Project of 1918,powered by one 300 hp
Hispano-Suiza 8 Fb engine
SEA.VI was a two-seat night bomber Project,powered by one 400 hp Liberty engine

 

[hesham]

From Le Fana 599;

P.80 & P.82 were a twin engined medium transport Projects
P.81 was a three engined low-wing light transport Project,powered by three Turboméca Bastan engines
P.93 was a twin jets transport Project,could accommodated 50 passenger

 

[Cy-27]

The Aviation Magazine de l'Espace No. 320, dated 1st April 1961, was dedicated the 50th anniversary of Potez aircraft.

It summarized many of the Potez aircraft families. A three page designations list was included in tabular form.

Its a large PDF, so may take a while to load.

 

[hesham]

Thank you my dear Cy-27,and here it's.

 

[chercheuravions]

hello, I found that on a french models website, do someone know this project? Because the designation of Potez 40 is already taken and it's look like the potez 231

 

[hesham]

hello, I found that on a french models website, do someone know this project? Because the designation of Potez 40 is already taken and it's look like the potez 231

Yes,it's Potez C1-40,and not Potez-40,it was a single seat fighter Project,based on Potez-230,you will see more details in my new book.

Welcome aboard,

and it's under construction now,it's about French Military Aircraft from 1919
to 1945,you will find a huge quantity of Projects in it for each company.

 

[Apophenia]

As hesham says, this is the Potez C1-40 S project, effectively an enlarged Potez 230 (in turn, a Potez development of the AMF Mureaux 190 light fighter).

Whereas the Potez 230 was powered by an HS 12X, the larger C1-40 S was to have a 1,300 hp HS 12Z engine driving twin turbochargers and a four-bladed propeller.

Specifications: Span 11.92 m; Area 19 m²; Length 9.71 m; Weight (empty) 1,800 kg; weight (T/O) 3,200 kg

Performance: 540 km/h @ sea level; 610 km/h @ 5,000 m; 675 km/h @ 9,000 m; service ceiling 12,000+ m; time to 10,000 m 14 minutes; maximum range of 1,800 km.

Source: L'aviation selon Drix https://aviadrix.blogspot.com/2016/04/

On the anomalous C1-40 S designation, I suspect that it simply stood for a generic Chasse en monoplace - 1940 ... but I'm not sure about the 'S' suffix. Perhaps it stood for suralimentation?

Thank you my dear Archibald,

and I finished it with my dear James Davilla,but we make a big review now.

I intend to speak about Potez list after WWII,from P.75 to P.94,and
in my new book a surprise about his early designation.

powered by one Potez 8 D-32 engine
Potez 92 was a single-seat twin-engined jet strike and close-support project with rear-mounted engines to compete against Breguet Br 121
Potez 93 was a twin jets transport Project,could accommodated 50 passenger
Potez 94 Super Magister was a training plane, a Fouga CM 170 derivative initially designated Potez CM 173

The Potez 60 was called the SAUTERELLE (Grasshopper).
The Potez 880 was not a version of the Potez 870. It was a low wing light transport and freight aircraft.
I have the Potez 881 as a military transport version of the Potez 880 with a protruding cockpit.

If I'm not mistaken, remaining model numbers mysteries are XIII (perhaps not used), 48, 550, 69, 71-74, 76-79, 85, 86. I don't know if there were numbers used after the Potez 94.

I correct Potez 880 & 881,thanks.

For Potez XIII,55,69,71,72 & 73,in my new book,you will find a good speculations
to how they were,very nearly the truth,but for Potez 48,we can say;

Potez 48 ? was unknown,but may it was a postal civil aircraft project,intended for 1929 up to 1931 competition,which the main contenders included ; Nieuport NiD-740,Bleriot Bl-110,Couzinet-28,29 & 30,SPCA-40T,Bloch-60,Bleriot 195/2,
Dewoitine D.29,ANF-Mureaux-140T,Albert A.20,Bleriot BZ-4, Breguet Br.380 ?
and Guerchais T.6

 

[Stargazer]

I correct Potez 880 & 881,thanks.

Just realized I wrote "880" twice. What I meant to write was "The Potez 880 was not a version of the Potez 870. It was a low wing light transport and freight aircraft."

Also I think it's not correct to write the Potez numbers as "P." since I don't think this was never used.

 

[hesham]

I add to the list Potez 76,77,78 & 79,as it's only my speculations.

 

[Stargazer]

Please note however that there seems to be a confusion over which was the civil version between the Models 880 and 881. Depending on the source, the 880 is given as the military version and the 881 as the commercial one (Aviation Magazine), or the other way around (Flight International). Since the only image with an actual model number on the airplane is the one of a civil "881", I believe the military cargo version with the protruding cockpit must have been the Model 880 and the commercial passenger transport the Model 881.

So what? Journalists have always made mistakes! Magazines make mistakes! Even authors make mistakes! (I once tried to list all the mistakes in an Alain Pelletier MiniDocavia book and gave up because there were just too many...)

Have we got a tentative designation for the B5 bomber project?

The answer is in my new book.

Potez 80 was a twin engined medium transport,powered by two Turboméca Marboré VI engines. Project

I add the definition of engines to the text.
