smoobles posted:also the more I think about it, there's no way they were at the ocean floor. If they didn't implode, it would've been a power or comms failure, and they would have dropped the ballast (which can be done with or without power) The ballast is dropped by either rocking the sub (lmao) or pressing a mechanical button. The ballast is supposed to deteriorated after 24 hours and raise the ship, but it obviously hasn't, so they probably died once the ship stopped sending telecommunication, or shortly before. My guess is that 7" thick 80lb acrylic window finally popped an hour to hour and a half in (it's supposed to have a visual crackle effect when it is about to fail, for whatever good that does), which sounds like it happened about maybe 1800m down based on people saying it was halfway down when they lost contact, when the window was rated for 1300m. Mfg often reduce the rating to cover their asses so that's probably when the viewport popped. Fun thing, at that depth, the pressure is equivalent to 250 atmospheres. Historically, on an oil rig when this happened, the pressure inside was 9 atmospheres, and they were on the surface. They didn't seal the diving bell correctly on the Byford Dolphin and the guy nearest the door became literally gristle as he got forcefully ejected, his organs spewing everywhere. The three other crewmen boiled from the inside and one person got smashed by the ejected diving bell, and another got seriously hurt by the bell. This was in 1983. My guess, is the glass popped and they either drowned and it fell vertically into the mud somewhere rather quickly, making the object even smaller to find on sonar, or, the pressure caused the bodies to eject out of the viewport like a unkinked hose, spewing gore and causing the ship to travel a distance away from the titanic in the opposite direction of the viewport, making it harder to find because it's a larger surface area to search. I think the ship probably would be intact in either situation.

If I recall correctly, the ceo said the window would compress down to either a 3/4 of an inch or to three inches, I forget what he said on video. Either way, not great. Even the challenger, which went to 35k feet, shrunk a little due to pressure. They had to use a special kind of foam with glass beads for the hull, because steel deforms and even titanium itself does. You need to make a titanium graphite alloy to overcome that, and it seems like it was just titanium

Also there were just one rubber seal on the front with like 10 quarter inch bolts holding it down lol

Eric Cantonese posted:Given the depths the submersible was intended to go to, you would need 4 km of tether. Carting that around would already be a massive pain and having that much cable thrashing around in ocean currents probably causes other potential problems. One of the ships they're sending over, the Horizon Arctic, has a FADOSS system which can lift 270 ton objects as far as 8km You're right, but it's possible.

bvj191jgl7bBsqF5m posted:The shark app tracks sharks that have been caught and tagged and rereleased. Pings are periodically sent when the tags are at surface levels where they can receive a satellite signal. I'm not sure if tiktokers think that sharks just randomly send out pings naturally or what. They do send out pings, actually. When they get close to the surface. These things have battery powered gps

500m away is a third of a mile away from the titanic... That's a decent amount of ground to search in the dark with sonar for a used to be pill shaped pod

Hazo posted:OCEARCH is a group that captures, tags (with acoustic and/or satellite receivers), and releases sharks and other large oceanic critters and makes their locations available to the public whenever the animals get close enough to the surface to "ping." The fact that two of them would register exactly where the titanic is, at that time, is very suspicious as to be unlikely. Maybe ocearch accidentally picked up their signal from the boat and it accidentally got assigned to the sharks

Hazo posted:For Simon to have gotten from where he pinged yesterday at 11 AM off Maine to the Titanic wreck coordinates at 9AM this morning, he would have had to swim at the great white's top speed of 25 mph for 22 hours straight. Yes, obviously the sharks didn't go there I'm saying the system picked it up, the ship, as the sharks. That's the whole point of the video.

I think in the future deep sea dives need to be designed like our space ships: docking ports, another, sister ship can attach to, and a means of going down there yourself instead of having to wait for the coast guard to putt putt at a measly 29mph (25 knots, which is fast by boat standards but slow as poo poo by emergency standards. I wish more boats traveled at 50 knots instead) Have two boats in case of failure. Maybe they can do something cool and go down there, dock with the crashed ship and get picked up by the not crashed ship. Makes sense in my head at least

Archonex posted:As a side note, do we know for sure it was at 4000 meters and not descending? What I saw of the presser seemed vague on that point. Other dive ships do about 500m per hour They were in the ship for an hour and 45 minutes They were thus likely around 1600m which was about halfway there

The Bananana posted:I... We've already seen a quick 15 psi (at sea level there's about 1 atmosphere of air on you at all times)->135 psi turn a pig carcass in a diving suit into a mushy paste over the course of a few seconds, on Mythbusters, to the point it even smushed the iron diving helmet slightly. they lost contact around 1h45m into the supposed 2-2.5 hour dive, or 83.33ft per minute at 2.5 hour travel. most places have said it was a 2 hour dive, though which would make it 104.167ft per minute distance = time * speed, so we know they were probably around 8750 to 10937.493ft when they exploded, that translates to about 264.21 atmospheres, or about 3,882.89 psi, assuming they were taking 2.5 hours to travel down there. It's much worse if it was 104.167ft/m because then it would have been 330.27 atmospheres, or 4853.61 psi. using that chart, we can also infer that these implosions happen quickly. Mythbusters did the diver compression test for roughly 30 seconds at 135 psi and if you weren't dead you'd have passed out after about 5-10 seconds at best while your flesh blood and bone just turn into a liquid. This was somewhere around 36 times stronger. edit: By comparison, James Cameron did the Challenger Deep dive in about 90 minutes, which means he was fuckin cruising around 400 ft/m GreenBuckanneer fucked around with this message at 23:16 on Jun 22, 2023 |

GABA ghoul posted:Not a materials scientist/engineer, but wouldn't you run some physical fatigue simulations before you build a hull out of a previously never used material? Or do repeated pressure stress tests with the materials in a lab? Or with a miniature in the actual ocean? Like, what made the guy believe a reusable carbon fiber submarine is actually feasible? Because he went down a few times so because it worked once it'll work again forever

ethanol posted:its pretty simple actually when its easy to design something so it can't happen instead of saying that will never happen Based on the video where he was talking about that controller, there's five of the controllers on the ship that they can swap out of something's wrong with the controller, and from his description it sounds like it was only used for the thrusters, such as the sticks themselves, also they were using the wireless connection. In any case I don't know why everybody is so up in arms about them using a controller when it was easily the least worst part of that entire design. Hell even the military uses Xbox 360 controllers to control their flying drones, they've talked about them using those all the goddamn time
