Designations of Avions Pierre Mauboussin and Peyret-Mauboussin

Louis Augustin Peyret


Pierre Mauboussin's designation sequence springs from his earlier association with pioneer designer, Ing Louis Peyret (ex-Blériot designer, ex-Morane Saulnier research chief, and tandem-wing monoplane pioneer). Those Peyret-Mauboussin 'PM' designation numbers overlap with Avions Mauboisson 'M' numbers (listed together in the next post).

Because Peyret's tandem-winged 'Le Taupin' is also listed as the Peyret VI, it is tempting to suggest that the Peyret-Mauboussin PM sequence follows on from an earlier Peyret series. Unfortunately, there's little sign of such a numbering system.

Peyret gave names to his earlier design but, aside from the Peyret VI and one Flight reference to a 'PM 4' (actually a typo for the PM X, see next post), there is no obvious aircraft numbering (although Peyret's airfoil designs were numbered). Peyret was associated with numerous gliders (eg: Georges Abrial) and tandem-wing projects (eg: with Louis Paulhan and the Albessard Triavion). Only projects with Peyret's name firmly attached are listed immediately below:

Peyret-Mauboussin and Avions Mauboussin Aircraft Designations

Avions Mauboussin


After his separation from Peyret, Mauboussin redesignated his designs in a sequence that derives the Peyret-Mauboussin designations. The PM XI and PM XII were redesignated as M.111 and M.112 (although still reported as 'M.11' and 'M.12' in the early 1930s).

Production aircraft designations were in a more typically French pattern. The production PM XII/M.12 became the M.120 with major developments following as M.121-M.129. Inititially, M.120 developments received suffix numbers based on their year of original (eg: the M.120/37 project of 1937 which led to the production M.123 Corsaire).

According to Flight (30 Sept 1943), after the Armistice the Mauboussin plant was engaged in glider production. But of what type and for whom? Did they receive Mauboussin designations?

Anomolies: The M 40 Hémiptère research aircraft of 1936 fits no pattern (I've placed it, in the French pattern, just before the M 400). And the Rouleur - a single-seat lightplane design with tricycle u/c - seems to have no number at all. I have listed the FM 260 Elite as the 'M 260' for simplicity. (That 'FM' doesn't seem to fit the Mauboussin or Fouga designation patterns. I presume that 'FM' refers to 'Fouga-Mauboussin' but have no proof.)

Undesignated (or unknown designation) types: The 1929 Peyret-Mauboussin Helicoplane project was mentioned in the first post, above. Another series of studies which lack (known) designations are the anneau (or ducted-propeller) studies by Pierre Mauboussin and Jean Kiriloff. For convenience, I'll place these études directly below.

Mauboussin-Kiriloff ducted-propeller projects
- Canard: Low-wing; 'V' canard on ext. nose
-- Also, a twin-boom, twin-anneau vers.
- Twin-boom: High-wing; single, large duct
-- https://www.secretprojects.co.uk/threads/mauboussin-kiriloff-canard-aircraft-projects.31624/

[1] In 1936, railcar builder Usines Fouga bought the exclusive production rights for Mauboussin aircraft designs - Mauboussin becoming Directeur of the Département Aviation of the Societe des Etablissements Fouga (later Société Aéronautique Fouga). Fouga built 60 x M 123 towards their Aviation Populaire contract and then developed civil versions after WW2.

Castel-Mauboussin CM Designations

Castel-Mauboussin CM Designations


Pierre Mauboussin joined forces with glider designer Robert Castello in 1942, their designs being known under the Castel-Mauboussin name and assigned CM designations. Fouga had been producing designs by Mauboussin since 1936 and, in 1944, made Mauboussin their Director of Aviation Services working alongside Robert Castello.

Fouga retained the CM designation sequence (which was distinct from their earlier Castel C- numbers). In May 1958, Fouga was bought by Potez which also retained CM designations for Castello-Mauboussin designs and their derivatives.

Here, I am presuming that, as the first built Castel-Mauboussin design, the CM Jalon would also be the CM.1. But I cannot be sure. Does anyone have access to 'Planeurs et avions Castel Mauboussin' by Christian Castello, Editions Le Lézard, 1994?

That book by Robert Castello's son has a chapter on CM projects and the index lists a CM "Mach 1" but no designation number is given. Another designation mystery is the 8-10 pax light transport project (2 x Bastan mounted on butterfly tail) mentioned by Jens.

Thanks very much, toura. I believe that the Peyret designs you posted are actually earlier than Mauboussin M.40, but content on the M.40 itself is very interesting. Would it be possible for you to post the next page in the article and to provide the source (name, issue, page, date)? Cheers, Matthew

The book "French Post-war Transport Aircraft" (Air Britain, 1980) by Chillon, Dubois and Wegg has an unbuilt Castel-Mauboussin derivitive of CM.10/CM.-100 family ....

CM.103R - as CM.101R with the two Turbomeca Marbore auxiliary turbojets. A military variant that was not built.

Excellent. Thanks for that Cy-27! But, if there was a CM.101R and a CM.103R project, there must be a 'CM.102' lurking out there ;D

The M.201 was not completed, and the unfinished aircraft possibly became the sole M.202. (Source: Avions no.164, article by M. Siffre.)

Castel 24 tandem two seat glider with an 18 metre span from 1936.

The Castel 242 was a 1941 development from the "Air Sports Service" with a new swept wing which offered poor handling built good soaring performance. One glider was lost in a fatal accident at the Challes les Eaux Centre in 1945. Other examples set a series of duration records 1946-1948.

Castel 25 was the side-by-side tandem two seat glider

The Castel-Mauboussin CM 7 was built in two slightly different versions in 1947 and later broke several height and distance records.

The CM 71 was a development of the CM 7 with a straight wing and no gull dihedral. Constructed at the Fouga factory 1951-52.

Castel-Mauboussin CM 8-13 aerobatic sailplane. 13 metre wing span.

CM 8-15 high-performance sailplane with 15 metre span.

Castel-Mauboussin CM 8-R15 jet sailplane known as Cyclone powered by a Turbomeca 011.

A Castel Castel-Mauboussin CM 310P development from 1950 was the Castel-Mauboussin CM 311P with improved de-rigging arrangement. It also had a longer fuselage, oval in shape (the 310 was flat-sided). New air brakes with opening above and below the wings.

CM 311P Data

Wing span: 45 ft
Wing Area: 158 sq ft
Wing Aspect Ratio: 13.3
Empty Weight: 346 lb
Maximum Weight: 540 lb


Some notes on Castel-Mauboussin types attached.


Sources:
Various cuttings that I am fairly sure are from British Gliding Magazines from the early 1950's.

Thanks Cy-27. Aren't the 310P and 311P usually listed as purely Castel designs?

You are dead right, Apophenia, about the 310P being a Castel design, I was too enthusiastic with my cutting and pasting! I will edit the earlier entry.

The CM 311P is described as Castel-Mauboussin in the article though, together with the CM prefix in all cases.

Interesting ... and confusing :eek: Thanks for checking Cy-27! The CM 311P has been added to the designation list.

Hi,

CM.102 was developed from CM.100 with retractable landing gear.

CM.120 was a military version of CM.100,maybe also with retractable landing gear.

Thanks Hesham ... that's been added. With its reduced wing area, the CM.131R would have been a better performer.

Thanks Hesham. Those same-as-'Cyclone' turbojets would, of course, be the Turboméca Piméné.

Above in the text, when L'Ala says 'CM.10', they are actually referring to the CM.101R ... with the "turbogetti posti dietro i motori Argus" being Piméné jets mounted behind the Snecma 12S piston engines. Presumably, aft of the 12S engines was the originally intended position for the twin turbojets which ended up being wingtip-mounted.

OK my dear Apophenia,

and also this new,it's offered in French language,but here is a google translate;

This testbed after the CM-170 takes the designation CM-180 and is expected to receive
the test reactor on top of the fuselage to the manner of CM-88.
