Hi,

some little known aircraft:
Delanne DL-190 sailplane.

[see this topic for all Delanne projects and prototypes — Mod.]
http://www.secretprojects.co.uk/forum/index.php/topic,15821.0.html
 
Hesham, nice website about french aircrafts here
http://www.aviafrance.com/aviafrance1.php?ID=2142&ID_CONSTRUCTEUR=202&ANNEE=0&ID_MISSION=0&MOTCLEF=
Enjoy :)
 
for all those interested I can as well advertise my own work :

http://modelarchives.free.fr/Bestiaire/index.html this page covers many weird French designs around the two world wars and all the texts are bilingual French / English

example :

Dorand's VTOL mailplane (thirties)

Fauvel AV31 transport plane (1943)

Lecheres patent for a VTOL flying wing (1943-44)

Hi,

Levy :triplane patrol flying boat of 1922.

Levy-Biche LB-4: single engined reconnaissance seaplane. [see here]
 
Hallo dears,

some little known aircraft:


Bloch MB.170 single engined single seat racer aircraft (not related to MB.170 twin engined reconnaissance aircraft).

Mureaux ANF-150 racer aircraft.

Bechereau (SRAP) T-7: single engined sesquiplane as transport biplane.
 
Hi,

The little known Lucien Chauviere Gyroptere of 1927,which powered by one
230 hp Renault engine.

Regarding to the Chauviere Gyroptere, the first look may be
misleading. It's not an autogiro, but a true compound helicopter.

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.

Sorry, there is not a single word of text about it. And the data do not mention weapons nor use. Only mysterious word that may have a meaning: "Laboratory Type" but that may mean simply "experimental", otherwise the use may be transporting measure apparatus for something scientific.

Probably an old French equivalent to "test-bed"...
 
This thread is really interesting : french projects of wwii was really obscure like title of this thread ! :)
Until now naturally : with internet ! :D
 
In the Trait d’Union #138, this is a mystery.
After the very classical Kellner-Bechereau E60 trainer (1st flight March 1940) is another 3-view drawing of twin-pusher with a weird wing. Nothing in the text there explains what this is. The only explanation I found could be a text 3 pages before in the introduction: "Béchereau designed a glider with a weird shape, a double crescent wing for a fighter project. From this glider project, Béchereau designed a motor-glider with two 7hp engines and the first drawer wing". The date seems between 1932 and 1936.

In the Trait d'Union #194 (Nov-Dec 2000): "in 1932, Paul Dutou designed a twin-boom pusher with Maurice Arnoux. Monoplane with low wing and a Salmson 9 cylinders 60hp. Not built."
EDIT: In the Trait d'Union #224 (Nov-Dec 2005) is this addition: "this twin-boomer was named D.T.G (unknown meaning), tested at wind-tunnel, removable wings. Length 7;5m Total weight 525kg empty 280kg speed range 75-185km/h"

In the Trait d'Union #208 (Mar-Apr 2003): "in 1934, someone named Goudant designed a flying boat with variable area wing. Two half wings (of 6.25m x 2m) disappear inside the the thick wing. 4 engines, speed near 300km/h, not built."

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."

Still in this Trait d'Union #217 is the wonderful tandem-wing Lachassagne family and also:
"Jacques Lagarde designed in 1936 with Richard a project of transoceanic airplane with 'controlled lift'. The wing featured (uneasy to translate!) 'des volets de courbure commandés par des girouettes Constantin' controlling Cz in flight. Span 62m Length 40m Total weight 105t with 15t load Power 15,600hp total Max speed 440km/h Range 8000km. The same Lagarde designed the Millet-Lagarde ML.10 twin-boomer after 1945."

As well:
A. Dujardin designed during WW2 a giant flying boat of 250t with turbojets (4 for lift and 4 for speed). Length 127m Span 106m.

Very interesting Tophe. I would love to read a bit more about that turbojet flying boat mentioned above. Would the position of the lift jets be practical?

I add the engines drawings. And I gave one line summary from 19 lines detail. I could translate more, but it is very technical, and I lack English vocabulary. I try.
"For speed, blades had 4.5m diameter and hubs: 3m. Blades were driven by a turbo motor located in the hub and working like a steam turbine but with air at pressure 12kg and 500°C. This air is provided by an engine room located in the hull. These propellers are adjustable around the vertival axis.
In the wings depth, were lift propellers of 10m diameter for take off, so it was able to take off from land. All this mechanical engine parts were weighing 60t, with a power of 140,000hp! Range 10,000km in 24 hours.
A reduced size model had been tested in 1937, as a 2.66m span model that was an air tubine with wings and a boom holding a tail. These tests were performed at Issy les Moulineaux in the Etablissements d'Etudes Techniques du Ministère de l'Air. The full-size air-jet project was not built."

Hi,

my dear Maveric spoke before about some French projects from WW1,and I
found an info for two of them,first,the Bassan-Gue BN.4,it was triplane
bomber project powered by three 450 hp Renault engines,and the second,
the Bille SACANA triplane bomber project,which was studied in three versions,
projects are provided with six (400 hp Lorraine or 400 hp Liberty) engines,and
the third one was a heavy bomber equipped by 700 hp SANA engines.
 
What was those projects from Couse Pratique d-Aviation?.

Most probably these are not actual projects, but sketches illustrating various engine placements on 3 and 4-engine aircraft.

The book title means "Practical Aviation Course". The text on 3 and 4-engine aircraft reads: "Three-engine aircraft do not have this defect to the same degree ; the engines are usually distributed as two engines mounted on the side and one mounted on the aircraft axis. Four-engine aircraft are still rare. The most frequent type has the engines mounted by pairs on the same axis, one with the propeller at the front and the other with the propeller at the rear."
 
Hi Hesham
Here is the Roussel 20

Hi,


FBA.12 was a two seat trainer flying boat,but I don't know if it was
built or not.
 
Hi,


the Astra-Nieuport company designed a large twin boom biplane with a span
of 25.5m,propellers were mounted at the nose of each boom,driven either by
a single central engine or or one in each boom,unclear if that aircraft was
still a project or never completed,that was in 1915/1916,who know more ?.

A small mistake,


the company was Astra and not Astra-Nieuport.

The Joubert J 3, which bears more than a passing resemblance to the Mignet HM.8 but, equally, differs in significant respects. Maybe its design was influenced by the HM.8. Maybe it was constructed using HM.8 components. Maybe it was converted from an HM.8. So far I've found next to no information about it. Does anyone have any?

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?

..........and now two equally poor images of the Volland V.10, a French two seat training biplane of the 1930s. However the stagger of the wings is such that if not for the struts, maybe it could be described as a tandem mainplane low/parasol wing monoplane! I think that I have slightly better versions of these photographs somewhere, but I can't find them at present. If I do and I can find them, I'll post them subsequently.

......and finally - for the present - the Botali-Mandelli biplane. I have a little information about this diminutive single seater, including the name of the gentlemen standing proudly before it. I think that he is either the eponymous M. Botali or M. Mandelli, its designer and pilot. I'll try to find that information and post it. But as before, if anyone has better pictures or more information about this aeroplane, I'll be most interested.

Hi Avion,


for Botali-Mandelli biplane,there is a more info about it in Trait d'Union issue 224,they also designed aircraft called PAMA and some light aircraft.
