Here is a more Info about this designer and his anther idea,from TU 291;

In 1932 Jean Simon patented a
boundary layer control device
called "turbo-rotor." This device consisted in adapting a turbo-rotor to
paddle or vane, mechanically driven, positioned at the center of
running over the entire span of the wing.
The air circulating on the extrados was sucked in and
repressed on the underside. Several provisions
of the idea were patented and a demonstrator was tested at the wind tunnel of
STAé in Issy-les-Moulineaux in May 1933
under the direction of the Chief Engineer
Lapresle. Built at Zodiac, on the
plans of Simon, this wing of experience
was constituted by a rectangular plane
thick profile: box construction
wood, duralumin rotor, mounting on ball rollings and steel bearings. The
motive power was given by two compressed air turbines placed at each end of the rotor. The dimensions were:
length of 1,430 m; profile depth
297 mm; 53 mm thick; total thickness with the rotor of 90 mm (the rotor exceeded under the intrados).

The tunnel tests demonstrated
especially that the rotor had to turn to a
extremely high speed. In the
it could not exceed 3,000 tr/mn,
which proved very insufficient, the aspiration
at the extrados then being almost zero. he
should have reached a speed of at
minus 8 500/9 000 tr/mn, which was not
possible with compressed air turbines.

From ROTARY WING AIRCRAFT HANDBOOKS AND HISTORY VOLUME 13,

Mr. L. E. Trouffion had begun a construction of a helicopter in 1928 ?.

Wonder if there is some joke in that piece: "Le Trouffion" is French military slang for "the low-rank soldier"...

With apologies for the picture quality - they are scans of contemporary newspaper photographs - here are two of the 50 CV Peitz Avionette. Does anyone have any better images of or information about this obscure little French aeroplane?

From Ailes 19/4/1958,

here is a Peitz-101 light aircraft.

Thank you my dear Jemiba,

The W. Margoulis was designed in 1922 tilt-propeller triplane,and powered
by two 320 hp ABC Dragonfly engines,mounted between the top two wings
and remained a project.
From L'Aeronautique 1922.

here is the Maurice Brion fighter,it was a single seat fighter biplane,and put the
upper wing behind the cockpit to make a good vision for the pilot,the aircraft
mention in Les Ailes journal and in Trait d'Union magazine also,may be intended
for 1930 C.1 contest,we know about 31 to 32 entries competed in this competition,
many of them remained a drawing board only.

From L'Aeronautique 1922,

also Mr. Maurice Brion designed and created some new ideas for aircraft shapes.
