Thanks to remind this poorly known twin-boom project. There were many De Monge other twin-boomers (7.2, 7.3, 7.4, 7.5, 150).

Tophe responded about there are many De Monge twin boom
projects,as he mentioned (7.2, 7.3, 7.4, 7.5, 150),and please
my dear Tophe if you have a more info or drawings to them.

I only found a the Model 7.2 project;

Hi Hesham,

Here-after some informations from "Aviation Magazine" (Jean Liron, date ?) and "Flugsport" (March 1925) concerning the De Monge Twin-boom aircraft and projects with a main specifications table and two photos (bad, sorry, copy of copies).

Translation of the table:
Type / Engine / Power / Span / Lenght / Height / Wing Area / Empty weight / Total weight / Max speed / Autonomy / Use / Crew + pax / MFG year / Registration / Number produced / Remarks:
Type 7-2: Not finished. "Grand raid" version autonomy: 7000km
Type 7-3: Scale model 1/3 of Type 7-2
Type 7-4: Scale model 1/3 of Type 150
Type 7-5: 2nd scale model 1/3 of Type 150


De Monge also designed a twin boom experimental glider which was engaged at the "Sailplane Offical Meeting of Combegrasse", France, in August 1922, piloted by Casale.

I will check, maybe next week-end, but I just had a look on my bibliographic booklet. Sources :
- Burnelli lifting body chapter :
Trait d’Union Bacalan Special : 3v of 7.5
Pilote Privé : 3v of glider 1922
Trait d’Union 171: details on 120
Jane’s 1927 : photo of 7.4, details
Aviation Magazine 383 : 3v of 7.3 and 7.4
The 7.4 and 7.5 were 2-seat models at scale 1/3 of the big 150 with 10 seats (the 7.2 having 32 seats)
- Pod and booms chapter :
Aviation Magazine 384 : 3v of 120RN3

That is all I have written down in the past. What should I check first, someday? (the Pilote Privé photocopy would be very difficult to find this year).

EDIT. The 120RN3 3-view has been posted by Hesham at http://www.secretprojects.co.uk/forum/index.php/topic,10809.0.html

Hi Triton,

The wording of "The Bugatti Revue " website can be misleading.
The photo shows in fact the full scale Type 7-5, which was itself a 1/3 scale model of the Type 150.

Thank you for this link!

Yes, this aircraft was registrated for the 1921 Coupe Deutsch but crashed on September 23, 1921, following a flutter problem.
Pilot De Romanet was killed.

Source: Book "The Speed Seekers" by Thomas Foxworth.
"During 1921 Viscount Louis Pierre de Monge de Franeau, owner, general manager and directeur technique of Etablissements Lumiere...decided to enter that season's major European air races with a new speedplane...his avion de course designated 5.1..."

Note: In the book is mentioned that prior the race, "De Monge was already at work on the design of a tailless flying wing, a type whose popularity was suddenly burgeoning."
Any information about this tailless flying wing design?
Thanks in advance,

I start from the end of the Trait d'Union collection, to get corrections before mistakes.
#175:
In 1922 Show was presented the Buscaylet-De Monge 5-2 fighter and a drawing of the 3-engined 7-2 (9000kg weight plane for 30 passengers on 1000km distance at speed over 200km/h).
Louis-Pierre de Monge de Franeau was a Belgium citizen, born in 1890 and deceased July 25th 1977 in New York. He built his first airplane in 1911. He worked during WW1 for the Lumière company. After the war, he stayed technical director for Lumière while creating his own design bureau. He designed and built many machines in France. After the failure of them, he went and worked in Belgium for Imperia. In 1937, he has been the designer of the Bugatti racer for the Deutsch de la Meurthe Cup.

From "Le Trait d'Union" #171:
The Type 120 of the Exino company founded by Louis De Monge was a 3-seater for night reco. A derivative with 2 engines of 400hp would have reached 230km/h and 7,000m (instead of 200km/h and 5,700m). The program it was competing in was canceled in 1932. The 120 never flew and the Exino Co. disappeared.

“Le Trait d’Union” #171:
- The Exino company created by Louis De Monge presented in December 1930 a project Type 140, three-engined airliner with inhabited wing. Weight 18 tons, power 2,000 hp total , flying at 230km/h 5,000m.
- A mock-up has been built in 1931 of a BN-4 class “flying wing” (like the Type 120). 245km/h 7,000m. Cancelled because the company disappeared.
- In 1935, De Monge designed a small 2-seat “flying-wing”, to be constructed at Starck and Guénot Co. With a Rubis-Péquignol engine.

“Le Trait d’Union” #164, texts without picture:

- Type 9-1: monoplane fighter with a 500hp Salmson engine. Static tests but not flown.
- 10-1: licence-built Koolhoven FK31 slightly modified of military class C2. One prototype built.
- 160: tourism single-engine two-seater, 1926, 1 engine Anzani 35hp.

According to http://www.aviafrance.com/aviafrance1.php?ID=3749
it seems a CN2 is "un Chasseur de Nuit biplace" (a 2-seat Night Fighter)

It is funny because the same aircraft appears on the front page of a document signed by Rolland Payen around 1940, and with Payen name written on the fins!

I required expert analyze from our Payen expert: dear Deltafan.
Si le dessin de couverture n'est pas un Payen, ça expliquerait pourquoi l'article n'en parle pas (les seuls Payen cités sont uniquement ceux que l'on trouve dans l'ouvrage d'Alain Pelletier : Les ailes volantes). Maintenant pourquoi y a-t-il marqué Payen sur ce dessin de de Monge ? Sais pas. Peut-être une simple erreur de l'éditeur et/ou une confusion avec d'autres projets Payen, comme le projet Pa.361 TP de 1937, qui a vaguement la forme de ce de Monge ?
In English: If the cover drawing is not a Payen, that would explain why the included article does not mention it (the only mentionned Payen being the ones found in Alain Pelletier's book "Flying Wings"). Well, why is it written PAYEN on the De Monge design? I don't know. Maybe a mistake by the publisher and/or a confusion with other Payen projects, like the Pa.361TP of 1937, which has a similar layout (?).
Thanks a lot, Deltafan, it is nice to have such experts among us! explaining puzzle mysteries...

BUT... all of this still doesn't explain why this picture clearly depicting the De Monge flying wing has the typical "NR-Payen" mention on the tail... My two cents is that Payen designed that for De Monge, or De Monge for Payen, it must have been a joint work at any rate.

I should think NOT. Take a look at this image: I have superimposed both designs after matching the scales and the orientation. I did NOT resize any elements separately not distort anything. As you can see, the shape and position of every element (wings, engine, cockpit, every rib and panel) is THE SAME (except for the tail fins). To me these are just two stages of the exact same design.

By this time (1924),the De Monge was associated with Buscaylet, and of
course it was not a fighter,but may be a racer or experimental aircraft.

Almost everything on de Monge can now be found in the book about the Bugatti 100P, which has a complete chapter on all of the de Monge designs!

'J.J. Horst' might just be 'Jaap Horst', the author of 'The Bugatti 100P record plane'
In that case, 'good read' would be more appropriate than 'great find'  :)

From l'Aeronautique journal 1923,


here is a strange patent to De Monge.

Interesting, four propellers, but why? More cargo capacity? Greater stability?  It seems that the smaller ones were connected to the main propellers.

To provide a contant airflow axis over the wing. Small outboard props were driven by the
exhaust gas of the main engines.

The way the props are cross connected would also reduce asymmetric thrust in the event of engine A or B failing.

I start from the end of the Trait d'Union collection, to get corrections before mistakes.
#175:
In 1922 Show was presented the Buscaylet-De Monge 5-2 fighter and a drawing of the 3-engined 7-2 (9000kg weight plane for 30 passengers on 1000km distance at speed over 200km/h).
Louis-Pierre de Monge de Franeau was a Belgium citizen, born in 1890 and deceased July 25th 1977 in New York. He built his first airplane in 1911. He worked during WW1 for the Lumière company. After the war, he stayed technical director for Lumière while creating his own design bureau. He designed and built many machines in France. After the failure of them, he went and worked in Belgium for Imperia. In 1937, he has been the designer of the Bugatti racer for the Deutsch de la Meurthe Cup.

My dear Tophe spoke here about Type 1.2,a 30 passenger aircraft Project.

De Monge also designed a twin boom experimental glider which was engaged at the "Sailplane Offical Meeting of Combegrasse", France, in August 1922, piloted by Casale.

It was called DMP-1.

Maybe it was... Maybe not. Do you have a link? A scan? Why do you post dozens of assertions like that in every topic, but without ever giving us a photo, an article, a reference? Are we just supposed to take your words for gospel truth, Hasan? I suppose I wouldn't be so demanding if certain forum members made such assertions, but in your case it's the sheer amount of them AND the fact that so many times in the past you misinterpreted documents that drive me to caution when it comes to you, sorry.

Google is your friend here, too ! 
The article mentions the "S.I.A.", which quite probably means the "Société des Ingénieurs de l’Automobile"
(Society of automotive engineers). A bit strange, as this would mean people workings mostly on cars, not
aircraft, but at least with regards to the engines, both means of transportation often share the same interests.
And especially after the war, a much more widespread use of aircraft as means of private (!) transport was expected
by many. And then an online translator can do its task by translating the two sentences at the start:
"considerations of the stuff for private transport" and "The S.I.A. discusses the question: Aircraft or helicopter?"
If really Louis de Monge is meant, I'm not sure, because the first sentence, which certainly caught your eye says
"Sous la présidence de M. de Monge ...", meaning "under the presidency of M.  (NOT "L." !) de Monge.
So, the article is about a discussion amongst the French engineers and manufacturers of means of transportation,
which way is better: The fixed-wing aircraft, fast, but needing runways, or the helicopter, slower, but able to take
off from nearly any spot.
That answer isn't complete, but shows, that there's no mention of an unknown helicopter and that the question probably is
wrong in this thread. And finding it took about ten minutes and very nearly no knowledge of the French language, just
typing in a number of letters and I think, that much research is reasonable for everyone here.  ;)


It takes a long time, before all mistakes are made ...

Yes, maybe that's right, it may well be, that Monsieur (thanks for the clue, Patvig) Louis de Monge was president of the S.I.A. then. I haven't found a forename during my quick search.
But what be the difference in this case ?

Yes Hesham,
Since most of the work of aeronautical engineers overlaps the work of automotive engineers, AE is often referred to as a sub-set of automotive engineering.
The Society of Automotive Engineers has a sub-organization of aeronautical engineers. The American Institute of Aviation and Aerspace Engineering is the academic side.
Even more narrowly defined is the Parachute Industry Association which includes manufacturers and PIA’s Sepifications Commitee maintains SAE specifications for parachute fabric, lines, hardware, etc. The Federal Aviation Adminstration and US military recognize PIA specifications as the successors to old Military Specifications. PIA specs are respected the same as SAE specs.
If you ask SAE about parachute specs, they will refer you to PIA.
