Here Jordan Giesige covers how the new gigacastings work with the exoskeleton.

PS, the meat is nine minutes in, but we've discussed this so much, his diagrams and background should be helpful.

I love how this man thinks though - first he's like 'robots, lots of them!' and now he's like 'alright that didn't work, um, big robot - SMASH!'

Good info..

If some aluminum panels had to be stamped one could stamp them at a mild Tensile strength, then after stamping heat treat them to a higher Tensile strength.

But using mild steel on internal panels will be good too.



For added rigid features for between skins (outer / inner Panels) Aircraft type
usage of ribs, stringers are a good choice.

Let's see what Sandy says when the final product is produced.

I'm a little concerned that he didn't consider that the sail pillars open, since a lot of people don't know that, and therefore contribute nothing to the exo-skeleton's strength for the 'triangles are the best' part.

Really useful to hear how the inner casting for the doors might work. Where the hell did he get that door teardown??? Lol

That's more how they're making the structural battery pack. The cooling fins are used as ribs while the cells take the translative forces.

There was a description when explaining how the window broke. They hadn't had enough isolation of the window while down. Anyhow, the description came with that diagram. Not sure who made it.

The inside panel if it does not open too will still provide lots of rigidity.

The strongest lightest methods of construction are used on large transport aircraft. Monocoque construction is a stressed skin with supporting ribs and attach structure. The idea of a stressed, exterior load bearing skin gets a boost due the angular panels of the CT. All of this should lighten the sub structure and allow for much more interior space.
The skate board of a structural battery pack also adds ridgitiy and again should free up interior space.
I have built Composite and aluminum aircraft from scratch and been working on large transport aircraft for over 30 years. Crawling into every imaginable space on all the Boeing and Douglas models as well as several others.

Finally, a very good explanation that shows you can have Exoskeleton, gigacastings and structural battery packs. This should cut back on all the posts that say things like "Now they have a structural battery pack the exoskeleton and 3mm stainless is a waste and just adds weight".

Awesome video!

It’s funny, the examples they had in Berlin had those cooling fins between cells, but the “leaked” packs Jordon showed in one of his recent videos does not. And Jordon seems to assume they will be cooled from below. Essentially his “version” shows what looks like a foam mat with hundreds of holes in it that the cells slot into.

I noticed those fins right off when I saw the Berlin photos and thought they‘d given up on cooling from the bottom. But I’ve heard elsewhere that the 4680 with fin design they put in Berlin was not based on the final.

It will be interesting to see how it comes out.

I found his weight estimates interesting as well. His guess of around 5600 pounds means at least some of them would not be able to be registered as Light Duty trucks.

I am still wanting to see a machine that can laser etch, bend 3mm SS and handle a 20' x6' structure.

Also I thought it was interesting that the inter panels could be aluminum. I am not aware of an aluminum to stainless weld process. If that is the case I guess they would use some type of glue. Maybe a UV activator?
