Little-Known French Projects and Prototypes

[hesham]

From TU 186,

CAUX:

At the Combeprasse congress, Jules Caux had registered a helicopter. This
machine, equipped with skates, had a rotor of 5.50 m in diameter, a length
of 3.50 m and surface area of 20 m° and an empty weight of 32 kg. Finally
only the glider will be presented.

Unfortunately,I can't find a drawing to it ?!.

I try to translate some of the text,

Aircraft with aerodynamic
automatic control
Avions Stabilex

Project for a single- to twin-seat artillery observation
aircraft of mixed construction with aerodynamic automatic control, see Fig. 134. The "Constantin" automatic control system is coupled to the elevator and ailerons, so that only the rudder is operated by foot.

Also there is unknown type,with a small part of translate,

The Jettisonable Cabin

Another solution to the problem of the safety of the stratospheric aircraft is the jettisonable cabin. While ejecting the pilot is undeniably the better solution for the classic single-engine, single-seater, it cannot be for a two- or three-seater aircraft. The realization of a jettisonable pressurized cabin for multiple occupants presents a new problem: the parachute, which must not only be capable of supporting the cabin but also of absorbing the enormous forces of the deployment shock. On the other hand, jettisoning the cabin must be possible without a shock at all speeds and in all attitudes.

What makes you think that these projects are French? Whilst accepting that my command of the German language leaves much to be desired, I could not find, in either page of text, or either drawing, anything to suggest that these projects are French.

All report is about French aircraft.

The section about Stabilex extracted from an English version of this report, probably translated by Mr. Pashingham in the 70s:

Many thanks to you my dear Philippe,

but which company did that ?.

It is written on top of the text: Stabilex!

Thanks, and can you believe that,there's no sign to it in Gallica site ?!.

What about the aircraft in Reply # 524 ?.

For what it's worth, on at least one occasion before the Second World War, the word Stabilex was associated with a Société "l'Équipement automobile et aéronautique" based near Paris. The connection between that firm and an observation airplane design which did not go beyond the drawing stage is admittedly tenuous at best.

Around 1935, the company in question developed a device called the Nouveau Nivex Stabilex. By the looks of it, that device, a gas exhauster (?? -- exhausteur d'essence in French), was a fuel pump which used the principle of negative pressure to draw fuel from an automobile's main tank and place it in a small tank positioned above the carburetor so that the latter could be filled by gravity.

Incidentally, the gentleman by the name of Constantin mentioned above appears to be the one mentioned in the second half of a VERY chatty text located at https://ingeniumcanada.org/channel/...-a-whirlwind-overview-of-the-fascinating-wind

Sounds very like the british 'Autovac' system . . .
