Arsenal de l'aéronautique ("Arsenal") projects

Was my thought, too, but as the registration was blurred with red colour, it would be logical,
that for other inscriptions the same colour would have been used. Additionally, I don't know
any other photo of this type, where the glider carried an inscription there.

I think, we should say here, referring to an old film title : richard, please take on !

 

[Jemiba]

Riddle solved, just by using a suitable source ...
Should have had another look at "Gerfaut et Griffon" "Avia Editions) earlier, there's the
attached photo, giving all needed answers:

 

[Jemiba]

Finished my attempt to merge the best available from the world of drawings and of photos, as,
just as in other cases, those general arrangement drawings are a not quite precise with regards
to details: The upper part of the windshield is more curved, the delta wing is pointed, the nose gear
is different and so on. That's no criticism about those drawings, just a reminder, that general arrangement
drawings are just, what the name implies and no precise and accurate source for details.
If I got it wrong on one point or another, please tell me, interpretation of photos often is a source for
errors.

 

[hesham]

Great drawing my dear Jemiba.

 

[Stargazer]

Great Jens! So glad about your dedication to put the rare projects in planform!

 

[foiling]

Yes, great drawing. Thanks Jemiba.

 

[Jemiba]

Thanks for your agreement, here's the corrected drawing of the 2301. One question is still remaining,
at least for me. Some sources state, that two such gliders were realised (e.g. Gérard Hartmann on
Hydroretro), others say, that the 1301 was modified into the swept wing 2301. The latter seems more
plausible to me, as photos are proving that both had the same registration F-WFUZ. Nevertheless, the
photo from "Gerfaut & Griffon", showing the canard configuration is said, that this was "one of the very
last configurations tested on the sailplane." Wouldn't that mean, that the 2301 was re-configured again
to the delta wing ?

 

[hesham]

Wow,great drawing my dear Jemiba.

 

[Jemiba]

And here's the third variant, the one with canards. It's principally based on the single photo, so
I consulted photos and drawings of the Gerfaut I, which had to my opinion a very similar tailplane
in a similar position. The canards seems to have had a clipped delta planform, for span and shape
I used a drawing of an early Gerfaut layout, which had canards, too, as a pattern. Other differences
to the "standard" 1301 seem to have been limited to the deletion of the pitots in front of the cockpit,
at the fin and at the wing tips, which were replaced by the long pitot with the kinked end at the nose.
And the faired over slot for the tailplane in the fin, of course.
Comments, clues and critics welcome !

In the March 2014 issue of the French magaazine 'Le Fana de l'Aviation' (N 532 - Mars 2014), there is an article about the Nord 1402 Gerfaut and the Ars.1301 .

Hi!
The Arsenal VG-70 jet-powered, swept-wing aircraft was utilized as a technology demonstrator over its short flying career for France.

"The VG-70 was put up for public display at the 1946 Paris Air Show and its formal ground testing began the following year which led to a first flight recorded on June 23rd, 1948. The aircraft performed admirably well despite the low output power produced by the Jumo engine and became just the second French-originated, jet-powered aircraft to fly. Despite the promising nature of the VG-70, its flying career was extremely short - limited to just five flights in all - as the project was formally ended during 1949. Attention had turned to an all-new jet-powered design utilizing the lessons learned in the development of the VG-70 for this development became something of an aerodynamic and mechanical dead-end - the airframe held little modification flexibility in terms of taking on newer, larger engine installations that offered increased output power.
It was intended that a related design, the VG-71, carry a Rolls-Royce "Derwent" turbojet engine of 3,500 lb thrust output but this would have forced an entire revision of the VG-70 fuselage - a project not worth the commitment in time and funding. The VG-80 was to carry a Rolls-Royce "Nene" but this initiative also fell to naught - leading to the VG-90, a jet-powered, carrier-based interceptor development."

Hi! VG-90 jet-powered carrier-based interceptor.

[blackkite]

Hi! VG-70,-71,-80 and -90. (Almost same scale.)
Please pay attention to the changes in the shape of the air intake.

Do you know what this project was?
Wing tip engines seems to be ramjet.
Variation of VG-93?

[blackkite]

Hi! Arsenal VG90 and competitors.

 

[Jemiba]

... Variation of VG-93? ...

Indeed, according to Jean Cuny, "Les Avions De Combat Francais", Docavia, those two variants
of attaching the ramjets were proposed. With regards to stability problems in the case of variations
of delivered thrust, the attachement under the wing, closer to the center line, may actually have been
better solution, I think.

Hey blackkite, no doubt, by shallow angle shape of the diffusers in the front of the engines, they're ramjets. Also, on the preceding page the post by Hesham, I think the engines on the wing tips are ramjets (although shaped differently) see image below. , Kevin
