here is the Jean Simon unknown helicopter project,there's no sign for this design
on Internet.

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.

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.

From Aerophile 1918,

I don't know if this odd airplane Project was related to Charles Roux or not ?.

This proposal is not for an airplane, but for a crash-dampening device. Sort of what the airbags do in modern cars.

From L'Air Revue 1928,

here is an unknown Project for Letord for transatlantic proposed,it was a high-wing three engined
monoplane and if the motors failed,it could converted into a boat,maybe it was the same which
mentioned in TU magazine as a postal aircraft ?.

Well, I took my old T.U. collection to gather twin-boom projects but I am glad to find another pearl:
From the same Trait d'Union #207: "In 1934, Pierre Gemy designed a machine that was not intended to fly but only to learn. What was called at that time a "roller" (? "rouleur" in French). When speed is high enough, only the main wheel supports the machine, with balance controlled by the pilot. Wing of 6m x 1m. Empty weight 150kg. Engine Harley of 14 or 15hp. Not finished in 1936. Actual rolling not confirmed."
That is fascinating! Kinda reminds me of this totally safe looking... thing: https://www.dailymail.co.uk/sciencetech/article-2026967/Low-flying-car-Ex-Russian-pilot-builds-working-prototype--soar-10ft-ground.html

Designed and built in 1934. As stated, Fernand Argoud's monoplane was powered by a Harley-Davidson motorcycle engine but, it seems this was later replaced by an Anzani aircraft engine. Some reports say that Argoud had two more aircraft under construction (he wanted to start a flying school - at Marcilloles-Chambarran aka Penol-Les Burettes - but this scheme was thwarted by the outbreak of WW2). Argoud's single-seat, parasol monoplane survives and his grandson is looking for a restorer.

BTW: Fernand Lucien Argoud had some formal aviation background. From April 1917, he was a mechanic with 2ème Groupe d'aviation at Bron. From February 1918 Argoud worked on SPAD VIIs of SPA 152 (Groupe de chasse 22) until being demobilized in 1919.[/U]
