The unlimited hubris reminds me of “Hot Rod” who built a gigantic catamaran called “The Flyin’ Hawaiian”.
Google it for a fun read, or look it up on Sailing Anarchy.
“It was used to glue the rings(that the titanium ends bolted to)to the carbon fiber hull.”
Maybe the stress was all compressive and glue seemed ok.
A dark way to put it, but quite possibly true.
The head of OceanGate was surnamed Rush [ראש], like at the head of the Torah, which always begins "in a 'Rush'".
The topic is the shattering of the vessel, so it has generated a lot of attention.
On Father's Day, no less, which always falls on the first day which is the 3rd [Sun]day of the month.
It's been mentioned on this thread that the cylinder [גליל] shape was very wrong, that the appropriate shape for this deep-dive vessel would have been a sphere ("round to equalize pressure on the hull" ~ posted by circlecity @19).
If I had a time machine (Oh wait, I do!), I'd go all the way back to Saturn V.
Now follow with me here, one step. That's because Titan also goes by Saturn VI.
Go back one step:
Saturn V. That's the alt. name for Rhea.
And? There must be a reason so many verses begin that way, with a vav, the letter of connection. So here you go, more spheres:
Etymology
Some ancient etymologists derived Rhea (Ῥέα) (by metathesis) from ἔρα (éra, 'ground', 'earth');[3] the same is suggested also by modern scholars,[4] such as Robert Graves.[5]
A different tradition, embodied in Plato[6] and in Chrysippus,[7] connected the word with ῥέω (rhéo, 'flow, discharge'),[8] which is what A Greek–English Lexicon supports.[9] Alternatively, the name Rhea may be connected with words for the pomegranate: ῥόα (rhóa), and later ῥοιά (rhoiá).
The name Rhea may ultimately derive from a Pre-Greek or Minoan source.[10][11][12]
Saturn V.
"Flow". It's a familiar "pre-Greek" source:
Flow.. around a sphere.. to equalize pressure on the guf (the translation for the hull of a ship).Ohr ("Light" Hebrew: אור; plural: Ohros/Ohrot "Lights" אורות) is a central Kabbalistic term in Jewish mysticism. The analogy of physical light is used as a way of describing metaphysical divine emanations. Shefa (שפע "flow" and its derivative, Hashpoah "Influence" השפעה) is sometimes alternatively used in Kabbalah, a term also used in Medieval Jewish philosophy to mean divine influence, while the Kabbalists favour Ohr because its numerical value equals Raz ("mystery").[1]
It is one of the two main metaphors in Kabbalah for understanding God, along with the other metaphor of the human soul-body relationship for the sefirot.[2]
Just another day of simple observations. Easy. So easy to ride the wave [גל] that I'm beginning to suspect that the world slaves away all day under the Sun in order to "un"see everything under the Sun. Fear of surfing?
Strange how this Rush guy was seeking out the aerospace industry for inspiration and manufacturing, in order to go to the bottom of the Deep:
OceanGate announced in February 2020 that it had partnered with NASA and that the Marshall Space Flight Center in Huntsville, Alabama, would 'serve as the facility where the development and manufacturing of a new aerospace-grade hull is completed'.The work was described as 'key to OceanGate completing its latest Cyclops-class submersible', which is understood to be a reference to Titan. But the pandemic struck a month later and thwarted the plan.
NASA said: 'For the safety of our team members during the COVID-19 pandemic, as well as limited resources and availability, NASA Marshall engineers only participated remotely in technical interchange meetings with OceanGate, providing consultation for materials and manufacturing processes based on industry standards.
'We did not provide any approvals for the project as OceanGate was the technical authority.'
MSFC. Their pride and joy is the Saturn V, whose models are on display at and in Marshall's official Visitor Center, at the Davidson center. Pics or it didn't happen.
See, the connections connect themselves.
This really needs to be animated: 🦂
Then to add insult to injury, rockets are best designed in the shape of a cylinder [גליל].
Stockton Rush should not have been in such a rush, but the Dark Side never learns because it already knows everything already!
Seen.. my tagline yet? The stuff that just sits there.
Let there be light.
❤️
geez... they dropped weights (which I am not sure what are the weights in that image), AND they dropped the harness, and they still were only rising at 20 feet per minute?
I would have liked to see 6-inch thick steel tube, if such a thing would even float
I have a 35 year career in the adhesive business. One day some guy called and asked about a sealant for a submarine hatch.
I asked “If it fails how many people die?”
That was obviously a question no one ever asked these guys.
In my case, it was a non-structural seal. It was just to seal off some trim.
I read when this was still ongoing, that the manufacturer of the porthole in teh front dome would not guarantee it to that depth..............
Damn.
And one of the most idiotic designs was there was no way to get out from inside. 17 nuts had to be unscrewed from the outside to open it. So, they could have bobbed around on the surfaced and run out of air.
The CEO had reported that the viewing dome had deflected inward about 5 or so inches during previous dives.
He was the Elizabeth Holmes, Barry Minkow, and Bernie Madoff of the engineering/adventurer world.
He was born to teach. So many lessons in failure.
I noted the flanged connection(flat) but did not see the gasket. In high pressure service, I would at least expect to see a metal ring joint connection.
How well did the glue adhere to the carbon fiber? Were severel types of glue tried out to find the highest strength?
>>Is there any record of an open-faced peanut butter and bread snack landing face up on the floor? No, I tell you, peanut butter is intelligent.<<
No contest with strawberry jam.
The man is dead. Let’s not pile on.
I watched the video of the “hull” being layed-up. It was a joke. There was a big spool, just like a thread spool, spinning slowly as 4” wide CF cloth was being fed in, all while a goofy guy was spreading the epoxy from a 5-gal tub with a drywall knife. There was no attempt to maintain an optimal thickness, and you could see huge air bubbles being covered by the cloth that were certainly going to form air pockets with reduced adhesion and increased crush deformation.
I’m surprised it made it down and back even once, but after two or three pressure cycles, it was sure to fail.
I’ve seen a couple of different videos of applying the CF to the cylinder. One was as you mentioned. I believe that is called a wet process. The other is a dry process with the epoxy already imbedded in the CF. That needs strict temperature control before being cured. They rebuilt the cylinder in 2019 after a few dives. I wonder if the first attempt was with the wet process and rebuilt it with the dry process..
None I know of, but any glue that can withstand 4000psi of pressure even a dozen times would sell.
"OceanMate glue: can withstand close to 5000psi of pressure (emergency) and 4000psi repeatedly (temporarily, and applied correctly on compatible materials. See legal statement).
In reality, there are some that at face value are rated that high:
https://www.permabond.com/resource-center/strongest-adhesive/
The strongest epoxy glue you can purchase is probably Systemthree’s T-88. This two-part adhesive has a tensile strength of 7000 psi. https://www.conro.com/what-is-the-strongest-epoxy-glue-i-can-purchase/
A toughened cyanate ester glue, almond some others
a tensile strength of 7000 psi...................
But what about Compression?.............
THAT is what we used to refer to as a "CLUE"....................
