Peyret-Mauboussin, Mauboussin, Castel-Mauboussin

Thanks Hesham. Was this CM.180 'testbed' actually built or did it remain a project?

@éro-Index lists a 'CM 180 R' as being mentioned in Aviation Magazine. Just what this CM.180R was to be a testbed for is a bit of a puzzle ... assuming that, like the CM.88 Gemeaux, the CM.180R was to be a testbed for Turbomeca.

It makes sense that the single engine mounted above the fuselage would produce somewhere in the range of the 1,760 lbf combined thrust of a standard Magister. The Turbomeca Aubisque put out 1,543 lbf but, with first run in 1961, seems a little late. As for other French engine makers, AFAIK, SNECMA's smallest 1950s turbojet was the R.105 Vesta producing 3,308 lbf ... which doesn't seem very probably either.

All a bit of mystery ???
 
Hi,

here is a Peyret-Nessle parasol wing monoplane;

Thanks, hesham and Apophenia, for this. Not for the first time, I have shared the information posted here on obscure light planes over at homebuiltairplanes.com for inspiration. I just wanted to let you know that your efforts in featuring very light aircraft projects and prototypes are much appreciated. There's a Czech company making a nice like 3-cylinder radial that would look great on something like this! Hmmm.... Cheers, Matthew

Edit: And here is an original French article with specs and some interesting details. It was actually a two-seater (though payload was under 300 lb!) and was a more sophisticated design than I had imagined. The ailerons, for example, used a sort of full-length anti-servo tab, presumably for a differential effect to reduce adverse yaw.

Does anyone have any images for the unbuilt, lower-powered designs that preceded the Fouga CM.170 Magister?

CM.130 - [Project] 1948 Fouga jet primary trainer, 2 x Turbomeca Palas turbojets
- CM.130: aka CM.130R, AdA considered underpowered with twin Palas engines
- CM.131: aka CM.131R,2 x Turbomeca Palas turbojets, 13m2 wing area
 
My dear Cluttonfred,

here is a drawing to CM.130R;

That was a misprint,it was called CM-210.
 
From Ailes 28/5/1949,

the translation;

[that the CM-101 will include a fully retractable landing, and, the CM-120 military transport,
small turbines gas that will be used for 'assisted' takeoffs with a payload more important than
that of the civil versions to private users./quote]

So, that misprint originated with Docavia 28 ?

Yes my dear Apophenia,

and that is explained in TU magazine.

From Ailes 13/10/1956,

CM-172 was a twin turbojets version of CM-171,intended for high altitude duty.

A second machine, CM-172, similar to CM-171,must fly in the coming months,Primarily, this second device was to receive two more reactors of the same program that "Gabizo", that is, SNECMA.R 105 "Vesta",or, Hispano-Suiz R.-800.
Since the success of "Gabizo",the development of these two reactors was suspended from less in an official capacity.
. As a result, CM-172 will also receive two "Gabizo" but it will be more carefully treated from the point of view
the pressurization, being intended for flights at very high altitude.It will have, in fact, a ceiling greater than 20,000 m. and will serve
to real scuba tests survival.

From Ailes 1/10/1960,

here is an Info about CM.209,to believe there was no CM.212,but CM.210.

CM-209 piloted by Jacques Grangette connected, September 15,
Toulouse to Stockholm in the day, with a short stop at
Hanover. CM-209 completed this connection of 2.250 km in
4 hrs. 30, from block to block, is an average speed of 500 kilometers per hour.

CM-209 and the recent version of the Potez-Air Fouga C.M-170 "Magister". the well
known reaction training two-seater. The CM-209 differs from CM-170 in that sense
that it is equipped with two Turbomeca reactors "Marboré-VI "instead of" Marboré-II ".
This "Marboré-VI" reactor provides a thrust of 480 kg. against the 400 kg. of "Marboré II". The
performance are significantly improved. The apparatus is further provided with additional tanks
at the ends of the wings which increase its autonomy. Presentations from CM-209,
in the hands of Jacques Grangette, took place in Sweden.

the CM-72 was derivative of CM-71.

Thanks hesham. Terry (Caravellarella) posted that list back in 2011 and it proved most handy!

I've corrected and updated my 'PM'/'M' designation list.

BTW: I had an M 120/34 photo link which refused to display. I'll try again here ...

From Flying 1952-6,

a Fouga CM.75 ?,I think it was a misprint.

Agreed. Elsewhere the exact same photo is identified as a Fouga CM.71. The high aspect-ration butterfly tail shows this to be n°1 - the CM.71-01. That aircraft crashed under test on 04 April 1952 (killing test pilot Claude Legrand and engineer Jean Lavigne).

The structural failure leading to the demise of CM.71 n°1 began with tail flutter. As a result, CM.71 n°2 was built with a lower aspect-ration butterfly tail. The third prototype adopt a more conventional cruciform tailplane.
 
hesham's L'Aeronautique 1937 (see reply #69) clipping is entitled Caractéristiques des prototypes MAUBOUSSIN. ... does this suggest that a prototype M 160 was actually completed?

Yes, these are "misprints". The aircraft shown is the first prototype CM.191 (D-9504/D-IHAM).

Doubtless the confusion came from Potez-Heinkel reps at the show who would have been pushing the production-version CM.192.

The latter was never built but online sources claim that SFMA Messier was to series-build the CM.192 variant. That can be safely discounted since Messier was never an airframer (IIRC, the 1934 Avion laboratoire Messier undercarriage testbed was the firm's sole foray into whole aircraft construction). The quoted Messier project numbers - 48046/48007 and 27457/48008 - were doubtless separate design requirements for nose and main undercarriages for the series CM.192.

I have updated post #3 with some details on the built CM.191 prototypes and the unbuilt CM.190 and CM.192 projects.
