2 LW fighters drop-tank in a french barn

[ouidjat]

Yeah Roland,

As you said " the "steel" is Zinc-coated steel-plates..." Humm, SO it's steel without zinc or not and since it's zinc-coated we can call it Galvanized Steel, can't we?
Left the fact with 0.7mm thick it's quite heavy, for sure. As you said too the assembly is different but I guess - I'm quite sure - it's thinner than the "normal" alloy hence thinner assembly joints (bending strengh capacity is different).
Last, pipe positioning is the same but the four plots are "mirror" positionned, one being in parallel with fuse axis the other perpendicular, and the contrary in bottom position. The "mirror image" of that disposition appearing on the other tank (whatever the first you are considering)
That disposition being planned to avoid lateral and front/back tank mouvement during evolutions.
This is interesting cause it means that the anchoring devices on tank racks had the capacity to be put right in place in those fences whatever their positionning (since the two little pipes are in the same position on both tanks).

Well, that's what I see on those pictures. Someone to comment/confirm?

Chears, Franck.

Merci bien.

Adriano: english only please!

[Adriano Baumgartner]

John: Roger Sir! Fully understood!

I appologize...my French was rusted...it was a simple message...but I will follow the rules.

Yours

To DB601E:

Please, were the photos posted on another previous thread or were they included on this thread? I can not really visualize those mentioned pictures, which I would like to have a look. My personal interest on the pictures is to enhance my 1/72 kits. That's all.

Thanks DB601E and all for the patience.

Adriano

Adriano, the pics are on this thread.
Send me a PM with an email address if you can't see the photos.

Hi Frank,
About the "mirror image" of the supports on the both tanks, is it possible that this can be a way to make difference with each octane fuels ?
If the plane engine must use this grade of octane, you can't install this type ot tank because of the supports positions ? This is a "poka-yoke" for those who works in Industry.
Just an idea of a Sunday morning....

An other pic of the alloy tank tail : heavy canvas with thin cardboard painted in blue , which use ? maybe for aerodynamics ?

Bonjour, Oui bien sûr.

I just took a technical point of view. Your's is available too: Is it possible that one Octane degree was more agressive than another one hence justified a different metal? I doubt, but why not.

Continuing my thoughts:
The tank was tightly secured on one point only: This being situated on central brace top and permiting a quick and easy release.
Four inversed "T" peaces of metal where introduced one by one in the four slots we are taking about to avoid pitch-roll-yoke etc movements and firmly maintained in place by a strong spring (One "T", one spring) always in compression, of course. This design helped to release the tank Of course.
I suppose those "T" had the capacity to turn around it's vertical axis when free, hence the difference between the two tanks.

Granville, I can see what you are saying only if the tanks were pre-fueled. I have never come across pre-fueled tanks.

ouidjat, is on the right track with his T peices.

Hi;

I wanted to resurrect this thread to ask if anyone had taken measurements of these tanks, such as diameter, length, distance between brackets, etc.? I would be extremely interested in this.....
