Tube🌿Timeoh wow, the Titan Sub accident investigation has a bunch of new documents on the US Coast Guard site: https://www.news.uscg.mil/News-by-Region/Headquarters/Titan-Submersible/
looks like the prototype hull failed. i can't really see the crack the report discusses but it looks like some sort of spalling or layer separation.
omg they reused the titanium domes and rings from the prototype!? also they covered the outside of the hull so there was no way to visually inspect it.
final hull testing was done to a safety factor of uhhhhhhhhhhh 1.09. that's more of a danger factor.
ahh yes unplanned environmental testing. this thing was stored, uncovered, outdoors, near the ocean, for 6 months! unbelievable.
more unplanned shock testing. the thing was pointing straight up with everyone in the sub up against the back wall, then it kept slamming into the launch platform for an hour. that must have been miserable.
omg the CO2 scrubber system is just a plastic container (for the chemical pellets) with a PC fan hot glued on top
the onboard computers appear to be off the shelf Neousys Nuvo automotive embedded computers. wow, i've worked with these before.
i'm getting some strong "my first gamer PC rig, what do you think guyz" vibes here
got some cable pr0n for you all. 🤮 who in their right mind would trust their life to this crap. smh.
everyone remembers the game controller. the stick extensions appear to be 3D printed.
found more pics. the O rings weren't properly designed, the one on the left sits too deep because the groove wasn't machined correctly. There's also a plunge hole (presumably to get the undercutting tool in) that is a serious weak point.
Bornach@tubetime They were probably thinking when has a failed O-ring ever been the weak point that led to the catastrophic failure of a hugely expensive vehicle while carrying a civilian to an extreme environment where only a tiny few humans can afford to visit?
