Not sure who was behind the Helicoplane but those tailless models were designed and tested by Robert Mallet between 1910 & 1914.
Span up to 4,5m.
Robert Mallet was helped by Gustave Eiffel.
 
My dear Retrofit,

I think he was the same person ?.

Attached is a poor retouch to give a slightly better impression of the layout of the A.E.R.A.L.T. Type 3. This 2-views's dimensions were unreadable. Fortunately, burunduk's clipping has those specs.

My dear Richard,

please give us a directs links to them,and thanks.
 
OK my dear Richard,and here you can download it;


and from TU 193,this Tourist Airplane;

Finally, last but not least, an article from Vie Lyonnaise presenting two photos of a tourist airplane
designed by Emile Chapeaux and piloted by Antoine Chailloux. The first official flight is dated
Tuesday, October 12, 1933 in Bron.

Equipped with a 60 horsepower star engine, it has a low wing and sedan, two faired shrouds
connecting this wing, of trapezoidal shape with great aspect ratio and rounded ends, at the
top of the fuselage. The aircraft is largely glazed and the tail units are triangular in shape.
Fixed train. Nice discovery by Jacques Delarue.

On Emile Chapeaux's 1933 tourer, perhaps this one?

Source: https://sites.google.com/site/bibliothequeslhada/

And a description from: Emile CHAPEAUX : ingénieur lyonnais et pionnier du vol à voile français

It was a low-profile thick-winged monoplane powered by a 60 hp Salmson engine with Merville propeller. The characteristics of the device are as follows: wingspan 11.75 meters, length 7.13 meters, height 2.07 meters, total weight 600 kg, maximum speed 160 km/h. On June 6, 1934, on the Loyettes airfield, near Ambérieu en Bugey (Ain), ground testing of the ACA aircraft n ° 1 (Ateliers de Constructions Aéronautiques) was carried out for approximately 20 minutes, then 4 takeoffs in a straight line for 800 meters. Friday June 8, Antoine Chailloux, former commercial chief pilot, succeeds in a 15-minute flight at an altitude of 300 meters. On the morning of Tuesday, June 12, the plane was flown from Loyettes to Bron. It reached Bron aerodrome in 13 minutes, flying at an altitude of 800 meters despite bad weather conditions. The next day, it is presented to the aeronautical authorities and to the press.

From TU 183,

Mr. Louis Clement built a single seat racer monoplane in 1919 and
a single seat ultra-light triplane in 1921,but he had also a design for
seaplane triplane of 1919.
Click to expand...
From TU-193,

During the First World War, Louis Clément establishments manufactured parts
metal for many manufacturers: Bréguet, Caudron, FBA, Letord, Michelin,
Nieuport, Sopwith, Spad, Tellier, Voisin. After the Armistice, they produced large series of
bicycles and presented at the 1919 Motor Show, a motorcycle built in
the workshops in Lyon and Boulogne-sur-Seine. If we add to these two establishments those of
Bordeaux, do we reach a surface of 20,000m? and a total workforce of 1,200 people.
Contrary to what had been written previously in this section. the triplane of
tourism will be presented for the first time at the Salon of 1919 and not of 1921. The train
tricycle landing gear has a 4m lane and a 1.10m wheelbase.

At the end of the First World War, the Lyon factory occupied 10,000m? and 600 workers. That
de Boulogne employed 800 workers. (45,100,120 to 132 Rue de Silly. Rue de Bellevue. 46 rue
of town hall). The offices were at 128 rue de Silly.

From TU 215,

Mr. Hildebrandt and his design;

Single-seater torpedo also planned as a two-seater, low-wing monoplane built in 1934 by Mr. Hildebrandt. In
April of this year, this amateur aircraft totaled 5 flight hours per 15 to 30 minute outings. He had been tried
by Paul Vaux, from "Aïles de Touraine",in Villacoublay on the Morane-Saulnier aerodrome, then in Saint-Cyr.

What is the meaning of "torpedo" here,a shape of it,or it was a military aircraft ?.

The word torpédo originally referred to an open touring car. So, in this context, torpédo suggests a 'sporty' tourer. (Perhaps a native French speaker could confirm this?)

Unfortunately, Google intentionally ignores accents. So, put torpille into Google Translate, you get 'torpedo'. Put in torpédo instead, you still get 'torpedo' ;P
 
From TU 175,

A.A.L. (Amicale d'Aviation Légère): New Manufacturer

In 1935, the AAL was incorporated in Lyon, which brought together manufacturers
2zators. In 1939, on the eve of the conflict, it had 7 devices
in flight condition, all built by its members: 4 Sky Pou and 3
more or less conventional types of aircraft. Among the 4 Pou-du-Ciel, the editor thinks that one found those of Messrs. Layat, Marron and Vérard, plus a fourth unidentified. As for the three airplanes, the
editor supposes that it is about those of MM Fellot-Lacour and Coulaud, more possibly that of Mr. Lemaire. These three machines are derived from the HM-8 type.

In 1938, construction began on a two-seater with a 65 hp Salmson engine. This work was continued more or less regularly during the war and in December 1944, after the Liberation of the Lyon region, the cell was practically finished. All that remained was to install the engine and the equipment and to make the canvas. But the web was then nowhere to be found ... The editor does not know if this machine finally flew.

In December 1944, 9 other machines were in preparation for re-flight
again or take off for the first time: the 3 Pou-du-Ciel Layat,
Marron and Vérard; the Fellot-Lacour aircraft; the Coulaud plane:
The Lemaire aircraft and three other light single-seater aircraft: those of MM Favier et Cie, Gautheron and Rodriguez.

Hum, not really "AAL new manufacturer": "Amicale d'Aviation Légère" can be translated as "Sport Aviation Friendly Group" and it was created in 1935 for and by Lyon area aircraft homebuilders.
 
Welcome back your return my dear Retrofit.

From TU 175;

BERTHIER (new manufacturer):

Craftsman carpenter in Ponthierry, near Paris, Berthier built in
1935 a light two-seater touring monoplane with high wing and cabin. This
machine was produced in cooperation with Rémy Gaucher, designer
itself from other machines. Writer assumes RG-40
Rémy Gaucher weekend.

In 1938, Berthier wanted to take it over to widen the fuselage and
replace the motor (initially an AVA). To this end, he established a
group to establish the bundle of this machine and searched, in
province, an industrialist specializing in woodworking.

This is how the SECAT S4 "Seagull" appeared.

The writer assumed rightly - Berthier built the Rémy Gaucher RG 40 Weekend at his workshops in Ponthierry. Unfortunately the better-known Ateliers Berthier belonging to the Odéon-Théâtre de l'Europe makes it almost impossible to search online for further information about the atelier Berthier in Ponthierry!

Is the implication here that the mysterious carpenter, Berthier, actually formed the Société d'Etudes et de Construction d'Avions de Tourisme? If so, that is odd since SECAT's factory at Boulogne-sur-Mer is over 300 km north of Saint-Fargeau-Ponthierry :confused:

On the engines, the first prototype RG 40 had a 26 hp AVA 4A-00, the second prototype had the planned-for 35 hp AVA 4A-02. The third prototype had a 60 hp Train - anticipating the SECAT IV/S 4 La Mouette. The postwar SECAT S 5 and larger RG 75 were both powered by Régnier 4D.2 4-cylinder inlines.
 
From TU 175,

who can ID those ?;

The unknowns of the section:

one will find below some snippets published in the newspaper "Les Ailes" and speaking of apparatuses of which the editor does not know anything. If readers have information, please pass it on to the editor. Thanks in advance.

- N ° 68, October 5, 1922: test report carried out near Paris of a 250 kg aircraft powered by a 6 hp engine, taking off in 8 or 10 m and performing a vertical landing.

- N ° 568, May 5, 1932: construction in Rouen, by amateurs, of a monoplane plane with raised wing, entirely in plywood and powered by an Anzani 45 hp. The device had not yet flown.

- N ° 735, July 18, 1935: construction in Toulon-la-Seyne of a machine with flapping wings, dragonfly type. It had fixed and flapping wings.

- N ° 754, November 28, 1935: Rayak. Two-seater low-wing monoplane guyed by two pairs of masts. Indian 2-cylinder V-shaped engine inflated to 15/17 hp. Timber construction. Fuselage covered with plywood, wings and control surfaces covered with canvas.

Dear richardB, thank you for the very interesting article posted by you 25.07.2021.

Could you, please, give the bibliographic reference to this article?
Thank you in advance.

By the way, is the designer the same Emile Chapeaux, who built in 1967 the motoglider CXD-18?

Here are both of them on the photo:

From TU 182;

CAUX:

In 1922, at the Combegrasse Congress, Jules Caux presented a biplane glider with half-couple wings (number 36).
The upper plane, at zero incidence is fixed while the lower plane has a variable, independent and uncompensated
incidence. Two vertical masts support the upper canopy. The center of gravity is located behind the shots, with the
pilot seated in the middle of the lower plane.

The flexible part of the wings is about 1 m °, it is obtained by bending the ribs. The tail wing, load-bearing, is not
absolutely stretched over the frame, in order to remedy the lack of drift.

Jules Caux made only two flights, on August 16, 1922, of 4 and 6 seconds. He concludes that the absence of drift
causes a sharp turn at the slightest maneuver of the lower planes and that the action of the variable angle of
attack is too great.

It is not known what subsequently happened to this machine, of which no characteristics are known.

In # 567 I gave the link for the story of the A.C.A 1 , and showed the article in post # 573 . The pictures where published in "La vie Lyonnaise" , but I am unable to find the original on the net ...
 
A little more about Emile Chapeaux :







 
From TU 186;

DEJOUY:

A former military pilot, Jacques Dejouy began in 1928 to study a small single-seater parasol monoplane. The drawing, apparently verified by Léon Levavasseur, was approved by the STAé.

The parasol wing, rectangular and without dihedral, is held by a cabin located between the engine and the cockpit. It is guyed by two pairs of parallel masts attached to the bottom of the fuselage. The train is classic with independent wheels. The engine selected is a 50 hp 6-cylinder Anzani, running at 1,500 rpm. With a wingspan of 10.5 m, it weighs 289 kg empty and 410 kg loaded.

Built in Casablanca, the aircraft was not allowed to take off from the airfield and Dejouy had to make the first tests from a plowed field. It was then fitted with 750 x 175 wheels.
The first flights took place in 1933. The aircraft shows a speed of 140 km / h. It took off in 30 m and landed in 26 m. The ceiling reached was 7000 m.

Alcya's technical bulletin N ° 2 mentions this device as type 4BA and its construction. in series is envisaged for less than 20,000 francs.

However, it will remain the only one of its kind, will be approved at the end of September 1934 and deleted from the Véritas register in 1937.

From TU 226,
here is a biplane,designed by Mr. Antoine Léglise;
July 21, 1927 designed a small sports device, single seat biplane canvas wood, fitted with an Anzani motor
three cylinders of 30 hp. It had been built in three years by Antoine Léglise,mechanic, assisted by MM. Chatard,
Plazanel and Pacros, at the Oyonnax flying club. It would have made its first flight to Chàlon-sur Saône and
totaled a dozen hours of flight in April 1928. At this at the time, Léglise did not have his patent pilot, whom
he spent that year at Pécole Sardier, his instructor being Dupoux.
In 1933, Léglise is mentioned as being at the flying club of Auvergne, but the whereabouts of his small plane
were unknown.

... From TU 236,

From Mr. Huttmann,who designed a helicopter in 1927;

Bernard Bombeau points out that 1927, a certain Huttmann proposed a helicopter with tandem rotors characterized by a rear rotor more lighter than the front rotor. This characteristic would result in that,when the angle of attack increases, the two rotors rotate at different speeds. generating, according to the inventor, longitudinal stability automatic.
Click to expand...

Apparently, not Huttmann but Hüttmann.

There is a description of the Hüttmann-Drehflügel Modell (Rotary-Wing Model) 1927, with an image, here:
-- https://www.pennula.de/luftfahrt-geschichte-1927-heft-20.htm

In Flugsport XVIII, 1926, page 292, a "Hüttmann Drehflügel Versuchsmodell" is mentioned. (There is also a "Studienmodell" or 'study model' on page 80.) The 1926 Hüttmann Drehflügel Versuchsmodell differed from the 1927 model in having a two-bladed rotor.
 
Thank you dear Apophenia,

but maybe his work was in France,because he was mentioned in TU
magazine,right ?.
 
OK my dear Richard,but certainly it was two Huttmann ?.

And from TU 182;

CAYRE:

In 1935, in Ruffieu in Ain, Edmond Cayre and his sons set out to fly by the only Muscular force. With a glider equipped with a propulsion device, one of the experimenters managed to take off. This take-off was facilitated by the slope of the runway take off, but upset by. the height of the grass.

The aircraft is in the form of a biplane with staggered wings with a wingspan of 7.40 m and with a bearing surface of 17.5 m °. It weighs 50 kg empty and 115 kg mounted. At the fixed point, the propeller traction is 10 kg and the speed obtained, on flat grassy terrain, is 30 km / h.
A second device, with an empty mass reduced to 35 kg, of better fineness and equipped with a upper traction, was studied. The author does not know if it was actually tried.
