And fresh from the printer, the Vulcain family.
Now working on Bacchus and Super Vulcain. More next week-end.

I like these projects. Never heard of half of them (and I've got a few books on European space projects on my bookshelf), but the more unusual the better.

Hello Folks  :)
Continuing my projects. Going to the last and biggest launchers: Bacchus and SuperVulcain, both of 1968.

Both shared a new first stage, called Octavie, which was a cluster of four Diane (from Carmen), each with two ejectors, making eight Vexin in total.
As with the Catherine cluster two tanks were devoted to nitrogen peroxide and two to UDMH with cross connecting tubing.
SuperVulcain's Octavie tanks were lengthened, so I included more pressure air bottles inside and a larger gas generator for pressurization of a larger volume.

I designed this stage using the same concept than Catherine, but adapted to twice the number of ejectors.

Here are the drawings:

... And the last but not the least: SuperVulcain (1968) of 363tons with a GTO capacity of 600kg, about the capabilities of Ariane 1.
First stage, enlarged Octavie, was to be a cluster of four Diane with lengthened tanks and eight modified Vexin engines.
Second stage, Catherine, was to be a cluster of four Améthyste with four modified Vexin engines.
Third stage was to be Coralie from the Europa programme with four L10 engines.

This completes my study of unbuilt French launchers. Now it's the time to print the masters, prepare the kits an assemble them. Lot of work left  :P!

Great job ! I really, really want to see Supervulcain B for "real" that is a model of it. You can be pretty sure it will be a unique model in your collection or even in the world (Supervulcain B ? what's that ?)

What scale for your model, by the way ?

Hello Archibald,
My kits will be at the standard 1:144 scale. Super Vulcain B will be 312mm high.
I plan to complete all these kits by next September. In the meantime I'll post pictures when ready.

And I'm still willing to made these kit available commercially.

I've stopped modelling a while back, but this is sooo tempting... my hands are itching...

Yesterday I started printing the small parts for Super Vulcain B.

Some parts (left of the ruler) will be replaced by photo etched ones which will be easier to handle, but the overall rendering is excellent.
Tomorrow I'll print the tanks.

I always liked SuperVulcain B because it is really the largest Diamant derivative and the real funny thing was, it was an Europa III or Ariane 1 class launcher.  It would be really awesome to get Supervulcain, Europa and Ariane 1 side by side on a shelf.

Also, SuperVulcain was just big enough, it could have orbited a Gemini or a truncated Soyuz (minus the forward, orbital module - that is, a Zond, albeit not a cislunar one)

If you ever heard of France Fights On, I'm really tempted to include Supervulcain B in their universe...

Continued...

Small printed corrections yesterday, and a new "big" part: the Bacchus inter-stage skirt.
This truncated cone was but a challenge for me, as that kind of thin part (.4mm thick) is a nightmare for most printers.
I spent more than an hour placing correctly the numerous temporary supports to get a printing without deformation and Yipikaï!, it turned very fine.
Tomorrow I'll have my last printing session on this project with the huge stage tanks.

And here comes Bacchus. These are only dry fit of the rough printed parts, just to give an idea.
Well, somewhat surprised by the size... I was expecting a smaller launcher  ;D

The printing phase will end tomorrow with Super Vulcain B.
