Hi,

does anyone hear about Salmson D-55,a two-seat light aircraft Project,which
was powered by one 60 hp Salmson 9 Adr engine ?.
 
does anyone hear about Salmson D-55,a two-seat light aircraft Project,which was powered by one 60 hp Salmson 9 Adr engine ?.

The short answer is 'no'. But it is an intriguing designation!

It would be tempting to suggest that this D 55 might relate to the 1950 D 57 Phryganet. The problem is that the 1937 D 56 Lycène was a low-winged trainer project for Aviation populaire. So, why did the D 55 not appear until seven years later? Very odd.

BTW: A lycène is a gossamer-winged butterfly (Lycaenidae family). Can any Francophone explain phryganet? I'm guessing that its is a coinage meaning 'little caddisfly'?
 
The D.57 Phryganet was powered by a 90 hp Salmson 5AQ-01 engine. According to Pierre Gaillard (Les Avions Français de 1944 à 1964), none of the CFA post-war 'Cri-cri' variants was powered by a 60 hp engine. I haven't yet had the chance to look to see what Charles Claveau (Les Constructeurs Français 1919-1945) has to say on the subject. As to the derivation of the name 'Phryganet', I would agree with Apophenia, the D.57 being the smaller brethren of the four seat D.21 Phrygane (Caddis Fly).

In Les Constructeurs Français 1919-1945 neither the entries for Salmson (which is extensive) nor CFA (which is not brief) contain any mention of a D.55 or any other member of the Cri-cri family with 60 hp engine.

It's from TU magazine,but the problem is that,if there were any designations D.51, D.52 or D.53 ?!.
 
According to http://fandavion.free.fr/salmson_entreprise.htm the D.55 existed only on the drawing board:

Pendant la guerre, alors que le D 56 Lycène à aile basse, également destiné à l'Aviation populaire, n'avait pu être construit, la société Salmson fut contrainte de produire, sous contrôle allemand, des éléments pour les avions Junkers. [Paul] Deville conçut encore le D8 T4 et le D55 de 60 ch qui restèrent sur la planche à dessin.

For D8T4,it was called Phrygane Major,and it was powered by one 150 hp Salmson
7 AQ-03 engine of 1941,all of them were a civil aircraft.

By the way,

Mr. Paul Deville had studied many military Projects from 1935 to 1937,but no
more details are known,and I suggest one of them at least was from D4 S2,a
twin boom airplane project ?.

I've seen the D4 S2 described as a biplace de tourisme. Not sure what military utility such a design might have.

I'm not sure but I suspect that the 'S' in the S.2 suffix was for Sport.

My dear Apophenia,

that suggesting to be more smoothly fusdelage with minor changes of course,but
I am niot sure,here is its description;

The D4 S2 push-pull

In 1934 Paul Deville studied a two-seater twin-engine aircraft in tandem with a push-pull formula, very innovative for the time. The aircraft was to be equipped with two Salmson 9 Adr 60 hp engines. the wing,cantilever and trapezoidal in shape, was placed on the back of the small fuselage. She had a wingspan of 11.40 m. Two beams, spaced 2.50 m apart, supported the empennages whose rudder, placed in the middle of the horizontal tail, was in the blast of the rear propeller and outside the deflection of the wing.
The fixed landing gear included two cased wheels at the front and a rear wheel placed under the vertical stabilizer. It was built as a wind tunnel model, but the formula seemed too audacious at the time for any practical realization to be undertaken. Its maximum speed was estimated at 200 km/h.

I think this one is new here, the amateur-built Greisch-Thuet monoplane (from Aviation Magazine International February 1967)

My French isn't very good, but it seems that the first flight took place in 1937 after 2 years of construction, the aircraft flew regularly until May 1940 when it was destroyed by occupation troops.

Powered by a 4-cylinder two-stroke AVA engine with 27 hp, registration was F-W066. IMG_8254.jpeg IMG_8256.jpeg IMG_8257.jpeg IMG_8258.jpeg
 
My dear Fabulousfour,

there are tens and tens of unknown civil aircraft and projects at this
period,from TU magazine.

From TU 182,

C.E.T.
(Technical Studies Center):

In 1941, gliding, the only aerial activity tolerated by the occupier, was restructured into 4 centers: Banne d’Ordanche, Montagne Noire, Saint-Auban sur Durance and Djebel Diss.
Material management is entrusted to A.S.A.M.N. in Toulouse (Air Sports Association
de la Montagne Noire) under the direction of Gilbert Sardier. Maintenance is carried out in the Factory Pont Rouge in Castelnaudary, purchased and transformed into a P.A.C.C. (Central Workshop Park Castelnaudary). A.S.A.M.N. also has a branch in Aix en Provence, the C.E.T. (Center of Technical Studies) bringing together engineers from AVIA and ARSENAL evacuated in southern zone.

In 1941, the CET. is brought back to the P.A.C.C. which is thus equipped with a Design Office composed of Messrs Blanc, Blondeau, Brilinsky, Copier, Loniefwski, Lyon, Marchetti, Presented, Rouxel, Sarrasin and Suisse.

Under the direction of Schweich, they will optimize the plans of Emouchet de Mangeot and in will pull a two-seater named Eider. This will be started secretly in 1943 at Du Maroussem. It will fly in 1948.

CLAUDEL:

President of a group called “L’aile tende”, Roland Claudel will study and create
gliders of early Zôgling type. A first machine, called RC-2, would have flown in
1933 followed by an RC-3.
A motor glider, known as RC-4, would also have been studied, it is unknown if it
was built.

This group was at the origin, in 1936, of the Popular Air Sports Federation.

It would probably be better not to translate book titles when quoting. Instead ...

In his book «L'Aviation Légère en Algérie (1909-1939)», Pierre Jarrigue cites an amateur builder named Conte who allegedly built a machine in Miliana. However, this construction may date back to before the First World War.

Author Pierre Jarrige
Publisher P. Jarrige, 1992

Besides Conte, Pierre Jarrigue mentions other amateur builders in Algeria: Fournier (Marengo), Mouraret, Ducceschi, Bonnefont-Péduplan, Seigle and Roland Lassale (Alger), Louis Poire and Paul Grégoire (Oran), Jean Olivier (Blida), the Jamme brother (Mascara), Marcel Brau (Hussein-Dey), and René Hirsch (Batna).

Thnak you my dear Apophenia,and from TU 183,

COQUERY:

In 1934, at the Club Aéronautique de Corbeil, Louis Coquery built a small
monoplane derived from the HM.8 and equipped with a 25 hp Anzani engine.
With a wingspan of 8.85 m and a length of 5 m, its bearing surface was
14 m2.

COULAUD:

During the summer of 1938, the Amicale d’Aviation Légère (A.A.L.) of Lyon
flew a light aircraft built by a of its members, Mr. Coulaud, in collaboration
with the engineer Arnaud. It will be noted that Mr. Coulaud was not a pilot
at the time and this machine was used for his first training. The device is a
parasol monoplane with open cockpit and powered by a 35 hp Poinsard.
The profile of the sail is a “Jacob profile” type 23012. After a few straight
lines on the Bron terrain and a slight increase in the incidence of the sail,
MM Fellot and Lacour made it make its first flights.
The aircraft, which was basically a derivative of the HM.8, survived the conflict
and was reactivated in 1944 in the absence of its designer then still a prisoner in Germany.

In 1948, the aircraft was taken over and improved, becoming the Coulaud-Meo 01
(F-WEAU). First equipped with a Mercedes 22 hp gearbox engine, it will be equipped with a 40 hp engine.

COUPET:

Pilot at Farman, Lucien Coupet, created, in collaboration with Guerchais, a monoplane glider called 1-01 which he presented to Combegrasse in 1922 with
the number 8.

The thick wing is in one piece and built around a main spar, spruce, of the type
box and located in the front third of the wing. The top of the sail is straight, the bottom in a slight V, achieving thus a thinning of the wing. The fins, long and narrow, are articulated on a false rear spar.
The one-piece fuselage also attaches under the wing using 4 bolts. Its section is
triangular; it is built around 3 cross-braced and cable-stayed spars. The position of
piloting is placed in front of the main spar. Only the head protrudes from the fuselage. The orders are classics: broomstick and rudder. The landing gear, initially composed of two skids elastic, will be replaced at the end of the first flight in August 1922 at Combegrasse, by a wheeled train, in steel tubes. Fully covered, the machine will then be lined with plywood on the rear half in order to improve its torsional strength.

Piloted by Coupet, it completed 19 flights selected by the jury between August 11 and 24. The longest will be 4 minutes and 50 seconds with an altitude gain of 53 m. On August 24, he covered 3.15 km in 4 minutes and 45 seconds, over a height difference of 600 m. |

When Coupet wanted to bring the device back to Toussus, he put it on a covered railway wagon.
of a tarpaulin. Unfortunately, a storm broke out, crushing the glider under the weight of the water accumulated on the tarpaulin. Only the main wing spar will be kept by Lucien Coupet as a souvenir.

That translation is quite garbled. And 'Combeprasse' is an obvious typo. Gliding activities took place on the slopes of the Puy de la Combegrasse near Clermont-Ferrand.

My take would be:

For the Combegrasse conference, Jules Caux initially registered a helicopter. This machine, equipped with skids, had a 5.50 m diameter rotor, disc area of 20 m2, overall length of 3.50 m, with an empty weight of 32 kg. In the end, only a glider would be presented.

By inference, this Caux "hélicoptère" would have been an unpowered gyroglider of some kind. That would also help explain its extremely low weight. [1] Still, it would have been one of the smallest-ever manned helicopters - with a slightly smaller rotor diameter than the Rotorcycle and even shorter than the Hiller.

Caux biplane glider: https://www.secretprojects.co.uk/th...ects-and-prototypes.15821/page-15#post-485712

__________________________________________________

[1] For comparison, the Hiller Rotorcycle weighed 140 kg (309 lbs) empty. But the Rotorcycle was powered by a Nelson H-63C engine - which, complete with cooling fan and shroud, weighed 34 kg (76 lb). Perhaps with the H-63C and its fuel systems completely removed, the empty weight could be brought down almost to the level of the Caux design?
 
Whilst not averring that such has been used for the French/English translations on this thread (not knowing whether this is so), perhaps this demonstrates the 'down side' of using google translate, and similar mechanical translators, in isolation. Without, at least, a good working knowledge of the language being translated, it is difficult, perhaps impossible, to assess the appropriateness of a mechanical translation and, if necessary, to adjust that to reflect the perceived meaning of the original text. At the risk of sounding trite, google translate, and its like, is a good slave but a bad master.

... Jean Delmas has a copy of a postcard whose caption reads: Marmande: “L’Etoile Filante” designed and produced by Mr Courregelongue...

Is there a date associated with this postcard? I am assuming that this Monsieur R. Courregelongue of Paris (who I believe was a lawyer).

Aéroclub member Courregelongue designed and built at least one other aircraft - his 1931 single-seat avionette belt-driven by an air-cooled 500 cc Chaise OHC engine - as per Dollar Type LSS (Entretube) motorcycles. If this design is related to your L'étoile filante, it features a very different wing planform at least.

According to a flickr poster, this machine was built in the workshops of Jean Paul Charrie (who also took the attached photograph). This Courregelongue-designed aircraft type first flew on 27 August 1931.

DELASALLE

Engineer of Arts et Métiers, Louis Delasalle (a single S) built and tested at Palaiseau in
1911 Chanute type gliders. We talk about him again at the beginning of 1925 since he then won the competition for glider training projects organized by the AFA (the French Aerial Association) with a device called Ikota.

The editor does not know more about this manufacturer and also does not know if this Delasalle is the same one who studied the single-engine, single-seat biplane LD-45 (1947) of which a two-seater version was named LD-261. LD645 and 261 are attributed to Louis Delassalle (with two S).

DERIVAUX:

After building kites between 1908 and 1912, Mr. Derivaux imagined a machine
original for the Combegrasse Congress in 1922. Inspired by his previous creations,
the device is composed of three pentagonal cells linked together by a central X.
He is made entirely of steel tubes and has “rotating wings”, a type of propeller of a
very special profile which, according to its inventor, must fix the device in the axis of the current air. These rotating wings are powered solely by wind. The device is equipped with wheels. Its wingspan is 6.60 m while the depth of the upper planes
is 4.60 m and that of the lower planes of 0.80 m. The total surface area is 34 m².
The curb weight is announced at 40 kg for a load of approximately 3 kg/m2. :

The device is brought to Combegrasse (competition number: 7) and its assembly started.However, designed to operate with winds higher than those which prevailed during the Congressional tests, he will not carry out any experiments. |

Umm, that is completely garbled ... being neither English nor French!

To rephrase, the Oiseau Bleu [Blue Bird 1] glider designed by the Landes Frères (Robert and Théo) together with Robert Derouin was presented at the Combegrasse Congrès in 1922 as number 38.

In any case, we already have a page for the Landes-Derouin Oiseau Bleu:
