French Aircraft Specifications 1919-1939

[PhR]

*** For the year 1934


-"C.1" single seat fighter; SPAD S.710,Morane-Saulnier MS.405,Nieuport N.160 & N.161,
Dewoitine D.513,Loire-250,Bloch MB.150,Makhonine MAK.110,and lightweight fighters;
Caudron-Renault CR.710,ANF-Mureaux-190 and Arsenal VG.30

This is probably an excellent example. I attach an extract of officicial synthesis document from French Air Ministry about this C1 program designated MT-CPT4, including its 4 editions: 13 July 1934, 22 August 1934, 17 December 1934 and 16 November 1935, as well as the next C1 program: the A23 of 1936. I also add my own tables.
All the 1934 C1 prototypes were initially developped from private funds by their respective manufacturers.

The Blériot-Spad 710 was eliminated (crashed).
The Makhonine 110 is a pure private study for a potential C1, probably designed for this program, but finally never presented to this competition, never ordered and never built.

The Ministry finally decided to allocate a part of the funds for these programs to buy some foreign competitors for comparision: FK.58, H-75 and Spitfire.

 

[hesham]

This information comes from a document from French National Archives, dated November 20th, 1931, which lists all prototypes under order at that date, category by category.

For this aircraft Guillemin JG.15,it ordinary to begin with that number,we have SAB Bordelaise also started
with AB.15.

For 1934 C.1 lightweight fighter,and we don't know the Bloch entry,so I think we have to suppose it was
MB.180 ?.

What is about Leduc RL.011,a fighter !?.

 

[PhR]

For 1934 C.1 lightweight fighter,and we don't know the Bloch entry,so I think we have to suppose it was
MB.180 ?.

Of course not!!
We don't know what was this project, Il only appears in CEPANA report, in the list of not selected project. There is no good reason for such hypothesis. It's just an unidentified Bloch light fighter project.

What is about Leduc RL.011,a fighter !?.

I published history and plans of RL 011 fighter in my book: https://www.secretprojects.co.uk/th...à-reaction-jean-lacroze-philippe-ricco.11775/

 

[PhR]

For 1934 C.1 lightweight fighter,and we don't know the Bloch entry,so I think we have to suppose it was

A little bit more information in "Les Ailes" of November 7th, 1935: https://gallica.bnf.fr/ark:/12148/bpt6k65539069/f3.item.zoom

In Courbevoie, in Marcel Bloch factories, […] A single-seater fighter from the new program, a faithful homothetic reduction of its big brothers, will be put into production quickly and should be completed at the end of January.

NB: the Bloch 180 was an unbuild seaplane project.

 

[hesham]

NB: the Bloch 180 was an unbuild seaplane project.

Where is that ?,and if it was a civil or military aircraft ?.

 

[PhR]

Where is that ?,and if it was a civil or military aircraft ?.

Oops, forget it. I missed to remove old invalid references from my notes.
It's my mistake due to typos in Les Ailes magazine (May 19th, September 9th, and October 13th, 1938). in fact, in the 3 cases, it's the Bloch 480.

Generally,the aircraft (MB.480) was completed in March 1938 ?,thus,my theory may be right about MB.180,as
lightweight fighter project ?.

[Apophenia]

...thus,my theory may be right about MB.180,as lightweight fighter project ?

Elsewhere, you had listed the MB 180 as a twin-engined light transport project.

 

[PhR]

my theory may be right about MB.180,as lightweight fighter project ?.

There is absolutely no reason to imagine that. Until you find a clue, please consider this as completely invalid!

 

[PhR]

*** For the year 1935

- Torpedo bomber seaplane ; Liore et Olivier LeO H-46,Amiot-150,Farman F.410,Loire-240
(later became Loire-Nieuport LN-10) and Bloch MB.480

This is the MT-CPT9 program. I published the detailed history of NC-410 (ex Farman F.410) in AFM, as well as the history of MB.480 in Avions magazine and in my first volume about Marcel Bloch. Gerard Bousquet have published the history of LN.10 in Air Magazine and in his book about Loire.
I also published a photo of the Fouga competitor wind-tunnel model in my book (missing in your list).

You are right,I missed it,here it's from Docavia.

*** For the year 1935

-"B.5" five seat bomber; Potez B5

I suppose you are speaking about the attached B5?

 

[hesham]

I suppose you are speaking about the attached B5?

I suspect in Amiot-180,it was for 1930/31 competition,and Dewoitine D.800 was for 1937 contest,also for SNCAC NC.110,the company had been formed in 1936 ?!.

 

[PhR]

for SNCAC NC.110,the company had been formed in 1936 ?!.

The history of B5 programs is complicated. A first edition was published in 1935 and modified in 1936. Some project were selected to cover this program and few prototype ordered (see attached).

In parallel, the Air Force general staff published a new specification for B5 in September 1936. So, at that time, 2 different programs were running in parallel. The Air Ministry published the official specification A20 two months later, which replaced the previous B5 editions, and the competition restarted.
Then, this new A20/B5 was updated 3 times in 1937 and 1938.

I also suspect a confusion between Amiot 180 and Amiot 380, but this is noted like this in original Ministry archive documents.

 

[PhR]

*** For the year 1935


- Long range maritime flying boat; Breguet Br.710,Br.720 & Br.730,CAMS-141 (Potez),Latecoere
Late.610 & Late.611 and Liore et Olivier LeO H.440

It's the MP-CPT10 program. For me, the Breguet 720 is a BN4 that does not fit this specification.
Also missing in your list: the Breguet 730bis, which became Breguet 830.

 

[hesham]

I also suspect a confusion between Amiot 180 and Amiot 380, but this is noted like this in original Ministry archive documents.

I can solve this,it's Amiot-180 already of 1935,because in 1934,Amiot re-allocated many designations,that
included; 150,160 & 170,meaning he re-used them again in another concepts,so the natural development
was Type-180,then in 1938 he created Type-380,and I have a drawing to Amiot-180 as a BN.5,and not B.5,
we can say; it's second use of the designation (Amiot-180/II).

And if you see that drawing,it clearly appeared as a modern version of Type-143,nothing more.

Also what was Wibault W.100,we know it had been developed as a transport aircraft ?.

 

[hesham]

The history of B5 programs is complicated. A first edition was published in 1935 and modified in 1936. Some project were selected to cover this program and few prototype ordered (see attached).

Again,the Potez B5 can't be supposed as Type-660,because this competition was from 1934,and Type-661
was appeared in 1938,so the previous designation (660) may create in 1937,but logically we can assume it
took Potez-55 ?

 

[Stargazer]

Also what was Wibault W.100,we know it had been developed as a transport aircraft ?.

Philippe himself clearly stated in this article from Avions Nos. 98-100 that the Wibault 100 or (Air Wibault 100) was the very large transport started before the war, and also designated as the "Wib.670" in some sources.

 

[PhR]

Now how come,in Le Fana magazine,they displayed all contenders in this competition ?!.

Yes, I know. I participated to this article : I provided the photos of the Bloch 500 to illustrate it. This information comes from Alain Marchand 25 years ago. In the text, Marchand underlines that, strangely, the Bloch 500 does not fit with all the specification. But since this, I found more information in Air Ministry archives, and I can confirm that the reason is that it was designed for another program and it was not a T3. The only Bloch project for T3 was the second Bloch 800.

 

[PhR]

Also what was Wibault W.100,we know it had been developed as a transport aircraft ?.

Please find attached the original source: an extract of the report from Air Ministry material committee of April 8th, 1938. They clearly state that Michel Wibault proposes a B5 based on its W.100 model under study at Arsenal. No more details.

I agree. This hypothesis comes from Michel Borget and I was never able to confirm it. Jean-Louis Coroller also sayed to me that he never found any confirmation of this in Potez achives. I remove it from my tables.

 

[PhR]

Now how come,in Le Fana magazine,they displayed all contenders in this competition ?!.

This list was published 25 years ago. Now I can fix some errors of this list. I attach my updated list, as well as an official one from French Air Ministry archives.
As you see at the end of the list from le Fana, the Potez 63-11 was not a T3. It has been used as replacement because none of the T3 contenders was finally selected.

And what about TU magazine in reply # 182 ?!.

Please find attached the original source: an extract of the report from Air Ministry material committee of April 8th, 1938. They clearly state that Michel Wibault proposes a B5 based on its W.100 model under study at Arsenal. No more details.

Of course,that was projected as a bomber version of transport aircraft,and may the twin engined fighter,
which came after,are W.200 ?.

 

[PhR]

And what about TU magazine in reply # 182 ?!.

Charles Claveau has just repeated what was published before him, including this famous error. This erroneous information was first published by Interavia en September 1938!

 

[PhR]

Of course,that was projected as a bomber version of transport aircraft,and may the twin engined fighter,
which came after,are W.200 ?.

What you says here has absolutely no sense!
Even with the same ID, Michel Wibault has proposed a 4-engine bomber to answer to B5 program, not a transport! The document speeks about a W.100 for B5, not the AW.100 for transport! There is no discussion about any fighter in the document I attached. Please don't mix everything.

I don't mix anything,I spoke about 1937 C.2/C.3 competition ?,and I supposed this designation.
