Just got a wire alert that says the U.S. Navy apparently narrowed the search zone and knows the general location of the sub, but everyone on board is believed to be dead. Edit: Coast Guard says they have evidence that the sub was destroyed or damaged by a failure of the pressure chamber. https://twitter.com/kaitlancollins/status/1671956815091826700 Leon Trotsky 2012 fucked around with this message at 20:04 on Jun 22, 2023 |

The hull of this thing was carbon fiber. I know carbon fiber is strong and light and cool, but it fails catastrophically. Why would you choose something that gives no warning of catastrophic failure? Hubris like this is why people are mocking them.

Arivia posted:neither - it exploded 487m away from the titanic in terms of north south or east west, not above it. When news of them losing contact first broke, I saw a depth of around 1800 meters mentioned as the estimation of their depth by that point. If so, around that point you're looking at roughly 2600 pounds of pressure. That Mythbusters clip says it was 135 pounds of pressure, so around 95 meters. And the suit doesn't appear to have lost containment so it stopped getting crushed once the pressure inside the (partially crushed) helmet and suit equalized. That... isn't going to happen when the groversub's structure failed catastrophically while under several thousand pounds of pressure. They would've been dead before they had time to register what happened, let alone feel it.

Old TV, monitor? (Don't smash those btw., shards don't stop moving after the implosion, you can absolutely get hit by them) Imagine that, but over a hundred times more force. And more violent, because water has more mass than just some air. The forces involved are difficult for humans to comprehend because they are utterly outside of our normal experience.

The force involved in the Byford Dolphin incident was much, much lower than in the sub implosion. At least an order of magnitude less. It's a good point of reference though. That was just some compressed air and it did unspeakable things to people.

The byrford dolphin pressure chamber was at high pressure of 9 atm, so when it was breached the pressure and contents were explosively decompressed to 1 atm. In the titan sub, the inside would have been at lower pressure than the outside, so the contents would have been crushed, not exploded

pumpinglemma posted:At that pressure there isn’t really anything you could make the hull out of that would have any intermediate phase between “everything is fine” and “soda can that’s been through a hydraulic press”. The moment any actual crack in the hull develops, the overall structural integrity is hosed enough that you’re on a one-way trip to Red Goo City over the next few fractions of a second. There’s nothing intrinsically wrong with using a material that fails catastrophically when it fails if every failure is already catastrophic. The complaint I saw, and I am not a materials engineer, was that carbon fiber doesn't hold up well to repeated stress. Which is fine when it's a bike frame and you can curse and lay down another few thousand, but is very bad on a vehicle that by its nature will be stressed repeatedly on every trip.

James Cameron had a few things to say:quote:“We’ve never had an accident like this,” James Cameron, the Oscar-winning director of “Titanic,” said on Thursday. I found this article because I was googling to learn more about James Cameron’s sub cause I kept seeing it pop up as an example of what to do right. Well it turns out that his sub also wasn’t certified because he didn’t feel like doing it. The difference of course is that Cameron’s sub fits 1 person and the only person who would be in it was Cameron himself, so he didn’t feel the need to go through certification. The one that imploded was meant for tourists and Camera says they absolutely should have certified it. Also if I understand what Cameron was saying in the last bit of the article, it would appear that the CEO might have gotten a warning from the hull integrity sensors that the thing is going to implode. What a way to go knowing that you’ve killed everyone on board but everyone else is too busy looking out the window at the titanic to know what’s going on.

I feel like the normal human experience that most resembles the timeframe it would take to implode is popping a balloon. Like, not in terms of forces involved or anything, but just how fast it appears to happen, how our brains can't even process it until it's over.

Yeah that's what I understood too from reading various articles. But Cameron says that the Titan, theoretically, has a network of sensors on the hull to tell the pilot the hull's integrity. The idea being that if the lights lit up the pilot could abandon the dive and rise back up. Theoretically. Practically he says with the carbon fiber material the pilot might get warned of an impending breech but would have no time to actually do anything about it. So he may very well have died after making GBS threads in his pants if he was warned about it ahead of time. At least that's what I understood from the article.

Which is fine when it's a bike frame and you can curse and lay down another few thousand, but is very bad on a vehicle that by its nature will be stressed repeatedly on every trip. - Carbon fiber composites are only very strong in tension. They are not particularly strong in shear or compression (typically slightly weaker than steel). The shear and compression properties mostly depend on the plastic matrix around the fibers themselves. Essentially you have a mesh of fibers inside a bunch of glue. If you put force on it so that you're trying to stretch the fibers, they're very strong. If you put force on it so that you're trying to just bend & push them around, the matrix will crack instead and the fibers will move. You can build a good tank for holding pressure in easily since the pressure is trying to stretch your tank walls bigger and elongate the fibers. Holding pressure out is harder - One of the nifty things about steel is it has a fatigue limit. If the amount of stress you put on it is small enough, you can load and unload it infinitely without any microscopic crack growth, so it never fails. Aluminum doesn't have that, any cyclic loading will increase cracks and eventually break it. Crack growth in aluminum is at least pretty well characterized though, and there is some ability to inspect for how far cracks have gotten. Carbon fiber composites don't have a fatigue limit either, but crack growth is less well understood + there is less you can inspect before it catastrophically breaks.

They didn't use bad carbon fiber but the company that built the tube for them did a poo poo job. ~4 years ago a 6x5' section delaminated and had to be cut out. The person that did the repair quit the company when the company refused to have it inspected to make sure the repair was done correctly. It's really god drat important to completely saturate the fibers with epoxy resin because on its own carbon fiber is just loosely woven cloth.
