Arsenal de l'aéronautique: built prototypes and unbuilt projects

[Apophenia]

Fantasies ... including their version of the VG 60. The Oct 1939 version was to powered by a 1000 hp HS.12Y-51 with Sidlowsky-Planiol 2-stage turbocharger - not an HS 12Z.

The Arsenal VG. 60 is one of my all time favorite French projects.

Hi Airborne,

but the designation VG.61 & VG.64,are they real one or fake ?.

... but the designation VG.61 & VG.64,are they real one or fake ?.

Yes, that's what Airborne2001 was asking. On his 'VG 60/VG 64 Revenant (Ghost)' link, you will find a host of fictional VG 60 variants listed - a bubble-canopied VG 60 (HS 12Z), VG 61A (produced by someone other than Arsenal), VG 61H (with HS 12Z-55), VG 61N (presumably Navale with unspecified armament changes), and VG 64 ("Late 1941" with an unnamed HS V-12 with "a Turbomeca supercharger").

Links in the specifications areas are to now-defunct WesWorld pages. I think that should be enough to confirm that these designations are what-ifs. (Perhaps Hood could confirm?)

Still, the Arsenal confusion continues ... On Justo's Le Fana table (676.jpg), the VG 60 is listed only as a 'Jummo 213E' (sic) powered 1945 project. It is the 1939 version of the VG 70 that is listed with an HS 12Y-51. However, in the text (678.jpg) is says: "Elles menèrent au type VG 60, totalement re-dessiné et qui dut commencer avec le moteur 12Z, inévitable groupe des projets de chasseurs français de l'époque."

That bit about 'like all French fighter projects of the time' seems abit overarching to me. With so much contradictory information on VG 60 development, nothing is irrefutable. It seems entirely plausible that, in 1939, Arsenal intended to power a prototype VG 60 with an HS 12Y-51 followed by production aircraft with HS 12Zs. Or, at least, that's the story I am sticking with ... until someone can show incontrovertibly that an HS 12Z was planned from the outset

I don't know of any French inverted 'V' engines but Arsenal used Jumo 213s on the He 274 prototype. Was the VG70 a late war or post war design featuring the Jumo 213?

I note that the 'VG 70' sideview in Reply #41 looks very much like the VG 60 in Reply #42. Is it possible that the Le Fana author has conflated the two?

I have the VG 70 as a Jumo 004-powered VG 60 derivative (work beginning in September 1944). The VG 60 was, initially to have an 'upright' Hispano (first HS 12Y-51, then HS 12Z). However, the VG 60's post-war (1946?) incarnation was, indeed, to be powered by an inverted V-12 Arsenal 12H (Jumo 213E).

The Arsenal VG. 60 is one of my all time favorite French projects.

Now there is this website here which mentions some variants:

However, I have never heard of any of these variants. Searches have brought up nothing. Are these real, or jest theoretical/fantasy developments?

From TU 170,

In April 1937, when Arsenal / Michel Wibault separated,
the state establishment had in progress, among other works, two
original achievements:

- The Air-Lamé-Guvot helicopter, designed by Colonel Lamé
and in the construction phase under the supervision of engineer
Sébastienne Guyot, whose steel blade was presented at the 1936
Salon. editor is unaware of any possible relation between this
machine and the Arsenal 40 helicopter (VGU 40) previously
reported in the TU.

- The Air-Galtier aircraft, named after engineer Galtier from
at Bernard, a company then disappeared. This project involved
an airplane very large radius of action, the realization of which
had been delayed by the financial difficulties of this same company
Bernard. The editor ignores all of this device.

Hi guys, there's my Arsenal VG.20

 

[klem]

In the field of supersonic research, France was also interested in the German prospects of the DFS to study at Arsenal at the Châtillon factory the "346" project in two versions "Avion-fusée supersonique" and "Avion supersonique à turboréacteur"

Hello,
I come back to VG-20: a big wind tunnel model (scale 1) was built and tested at Chalais-Meudon.
In 1940, the German troups captured this model in Arsenal Hangar at Villacoublay, with the huge Arsenal Air-Wibault 100 prototype under construction. I attach a photo of this model from my collection.

Amazing my dear Philippe,

and as you know,there were 9 different aircraft,carried this designation "VG.50".

I do not know how you established this number of 9 projects, but it is true that VG-50 designation was reused as generic number for multiple projects. It was initially a fighter, member of VG-30 familly, but during war, it was assigned to a bigger experimental plane for engine coupling experimentation. Some additional usages were suggested to justify the efforts of the team in Villeurbane: transatlantic, maritime patrol, etc.
I attach a side view of one of the latest versions.

What is the powerplants with those contraprops?

What is the powerplants with those contraprops?

Good question.
Michel Vernisse filed various patents for a mechanism "homéoceinétique" for engine coupling. The VG-50 was planned to be used as engine testbed for such coupling system. The engines planned were 4 Hispano-Suiza 12Z, coupled by pairs.

Hi,
8 years ago, you told us in a special issue of the French magazine Avions, that the Arsenal testbed Latécoère 299A (tandem HS12Y31, contra-props) had made three flights (April 25, 27 and 28, 1944). Until then, it was accepted that it had been destroyed before its first flight.
Do you know how these three flights took place (breakdowns, problems or not, speed reached, etc.)?

Please ,I heard that there was those Arsenal designations VB.11,VB.12 & VB.14,we know an odd designation in this series,called VB.16,who can
explain that ?.

Actually in this period,Arsenal developed a nine projects from VB.10,
included VB.15,so may their series are from VB.11 to VB.19 ?.

You have now raised these 'designations' five times in this thread but we still face a number of problems here ...

1 - What was your source(s) for these "nine projects from VB.10" (as well as for your unattributed attachment)? [1]

2 - Which VB 10 design is being referred to here? Is it the original June 1938 concept (eventually prototyped in 1945-46)? Or is it the 1944 'Aile Volante' (with 2 x wing variants)?

3 - Arsenal was known to apply 'cover' designations to various VB 10 projects to disguise their on-going work from the German authorities of the zone occupée. If such 'designations' existed, they may have been nothing more that 'covers' for the planned reconnaissance-fighter or any other proposed variants or série types (which you, yourself, have listed).

4 - Your rejoinder in reply #74 stops short of being an actual logical fallacy ... but it comes close.

but we must search good before confirm they were not existed.

In effect, your argument is a demand for others to disprove 'designations' which existed nowhere online besides in one of those nonsensical Wiki 'reference loops'. [2] Without reference to actual documents, such circular 'sources' are worse than useless (and highly damaging to Wikipedia's reputation).

When in doubt, it is better practice to list positives rather than to demand proof of negatives.

_______________________________________

[1] In reply #77, you list unspecified TU and La Fana issues as sources for 5 x VB 10 variants (to which we could add the unrelated VB 10 'Aile Volante' concept with two wing types).

[2] IPFS is a peer-to-peer network acting, in this case, as a mirror of Wikipedia.

From Le Fana Nº 197 to 200

I was able to look at the radiator photo through a translater, and the VG 60 radiator was huge. Perhaps it was for a "Mega-Miranda Effect" of sorts, even more so than the P-51?

 

[hesham]

My dear Apophenia,

you don't understand me at all,and you mix between two things,the
nine projects were really existed,but about the VB.11 to VB.19,that's
only my speculation,however I spoke about VB.10 of normal shape,
not the tailless one,but I can't talk about them because they are a
part of my book.

Then why keep bringing them up?

To know the real designations for them ?!,we only have the
VB.15 and VB.16 from reliable source,so I seek for more.
