https://www.youtube.com/watch?v=dQCvtPS2fLc Seems there are seven separate systems for surfacing the sub.

A 1000m depth. If a submersible is cracked, the water fills the airspace in about 100ms, and creates a compression ratio of 100:1 (a diesel engine is about 13:1) which ignites anything inside at 20,000°C. At 3800m it's a 380:1 compression ratio.

I doubt they imploded though. Some French guy said the implosion can be picked up on sonar and happens in 20 milliseconds at that depth. With that stupid frame thing around it and all the bits to catch on. I think they might be entangled on the Titanic or the wreckage in the trench around it due to the strong currents. Therefore the seven (7) separate systems to get positively buoyant do gently caress all. Maybe an electrical/hardware/software failure or fire?

Look at all that poo poo on it designed to get entangled.

Can a mod change the thread title to Submersible on expedition to Titanic missing please?

Does anyone understand exactly how the submersible communicates with the surface ship?

^^^ P.J. HarveyRalph Crammed In posted:Starlink, evidently. As far as I can tell, it's whatever kind of internet Starlink sends out. As to how well that works under miles of water? Not great, evidently! To be fair, this hasn't been a problem for anyone up until now, so I can't blame anyone for not really knowing how well wifi or whatever Starlink is works in the deep abyss. I personally, as a billionaire, would have used a 3.8km long fibre optic cable on a sturdy cable attached to the submersible for comms. Although I suppose that could get entangled. Maybe some directionally-focused sonar system as well? And the big rear end winch on a ship could pull you up with great force if you were to become entangled, whereas with dumping ballast at zero buoyancy there is gently caress all force to break free at first. Good thing I'm not a billionaire

Well, I was wrong about the implosion, but that's cause the French guy said it would have been immediately picked up on sonar. Which turns out it was. I also made up the 100ms thing. I think it's much faster than that. All the other poo poo I said was actual physics.

EVERY TIME GOING posted:For every 10 meters of saltwater depth, multiple sites say that pressure increases linearly by another atmosphere. So if the ill-fated explorers were still descending at a depth of about half a kilometer, then the pressure surrounding them would've been 50 atmospheres (Titanic settled at the edge of the Abyssal zone at 400 atmos) when something in Titan's hull began to fail. The following catastrophic pressure equalization took the craft's internal sea-level atmo to the outdoor 50 in a near instant, which is a hell of a lot of force to exert on the human body. Even a much smaller 9 atmo change, referring to this oil rig decompression article, Here you go buddy.

I'm also reminded of the time when I was a kid and made an A-frame "shelter" out of some lovely logs and sticks. I was laying in it, just chilling out reading a book and heard a creaking noise. I was like "Hmmm. That's interesting." Then the structure I had built with my own hands had a catastrophic failure and collapsed. I suppose I'm wondering if there was a bit of a creaking sound that was audible just before they ignited (diesel power) and were then crushed/extinguished.

Dr. Cool Aids posted:guess you're all lubed up and ready to go but until this one detail is ironed out you can't start really going to town gently caress off mate. I'm all about the science my dear goon. E: I suppose most things when you increase the pressure make sounds. So maybe the thing was popping and creaking all the way down?
