Thread 16703035

How do you do this properly without getting everyone killed?

The implosion was actually a good thing because they can use the data they got from the accident to engineer solutions to prevent it from happening on the next version of the submersible, it's all progress towards getting the right design to dive consistently deep in the ocean and come back safe!

use a material that resists external pressure.
carbon fiber is only strong under tension, which in the case of a tube means only when the internal pressure exceeds the external pressure.
external pressure applications are a whole different design process.
t. mech eng, mostly work with pressure shit

>>16703035 (OP)
bathospheres have been doing it without imploding for decades

Accept that at some point the sub will fail. The trick is knowing when. So use a material that alerts you before it's about to fail. Scan, record, track and predict micro fissures in real time, and failing that pre/post mission.

What people don't realize is that Titan has been down to the Titanic like 15 times before without any issues

Rush is still a fucking retard because he knew about delamination but it's not like the vehicle just imploded the first time they tried it. If you want to know how to REALLY do it see Jim Cameron and his autism vehicles for getting to the bottom of the mariana trench, they are solid but extremely expensive.

>>16703039
No one has learned anything. Everyone knew the design with inherently flawed, except the CEO who believed he knew better than every expert in the industry.

>>16703035 (OP)
Don't go in. Even if the fucking thing is indestructible DONT GO IN IT!

humans are meant to be on land and stay in land. Not under water or space. LAND!

He cut corners and winged things every step of the way, it's miraculous it stayed together for as long as it did.

Good lesson not to trust something just because it's worked before.

>He cut corners and winged things every step of the way
just goes to show how most things are over engineered.
people meme on the logitech controller but that wasn't the point of failure, and it saved them easily 6 figures over a custom solution to do the exact same thing.

Lost tech. Finland did these (shown in the 90s movie). CIA got mad and demanded that we stop being the best (and sell to USSR)

>>16703059
seems more reasonable to accept that a material that will fail is unsuitable.

>>16703551
treat the pressure vessel as a wear part and replace it every 10 dives or so

>>16703059
That's what they did. The instruments worked. They were too dumb to interpret the data properly.

>>16703104
I was just making a joke about starship lol

>>16703035 (OP)
if it was made of steel it wouldnt have imploded, repeatedly reusing a carbon fibre hull was very stupid

>>16703561
that doesn't sound economical at all, and still unsafe af

heavier than du u sink it indeliberetly

>>16703498
I thought people joked about the controller because he didn't have a backup steering method

>>16704120
The reality is that thing had wired qwerty keyboards that probably were usable as backups because they were hooked up to the same computers as the logitech controllers. But that's not as hilarious is it?

>>16703035 (OP)
This is a solved problem trying to be "innovated" by a now dead rich retard. The only person I feel anything for in this is the teenager that was aboard.

The solution is to tell your customers you hit the bottom then have a drone act as the camera at the real bottom which they control.

>>16704120
People clowned on the controller because he used the shittiest 12 dollar wireless logitech controller he could possibly find. There's a reason the military uses wired controllers produced by console companies, and not logitech. Wireless introduces more points of failure, and there were multiple times where it failed to connect to the sub and they were left spinning around in circles underwater.

I doubt the controller even underwent calibration outside of the first time they used the thing, or regular replacement.

>>16703035 (OP)
Oh I don't know, maybe you could just follow the proven designs, principles, methods and materials that are already long been established?

1st-
ram it into a the jaws of a reaLLy big sHark
2nd-
get out your 30 cal .30-06 rifle (no wussy .308s allowed)
3rd-
SHOOT it several times

If it doesn't eXPLode, your sub is good to dive-dive-dive
-but you're going to need a bigger boat...

>The Moar U Know...

Stockton Rush when building the Titan borrowed carbon fiber technology from the Boeing 787 program, and enlisted eng/fab help from the UW Applied Physics Lab, who had Navy contracts to develop a better TORPEDO...what could possibly go wrong?

>>16703035 (OP)
Maybe start with a personal version.
>>16703039
Reminder that Elon Musk's pedo sub has never been tried. Someone should get on that to see if it was viable or just another loudmouth CEO with an out of control ego.

The certainty of steel.

>>16706421
You do it like the people at Woods Hole do all the time without issue. This once again proves that we should publicly fund science and not leave it to eccentric billionaires and shareholders. Conflict of interest and unpredictability.

>>16707609
These people don't even pay taxes and cutting funding for science increases their profits. Simple corruption, something that destroys nations.

>>16703035 (OP)
Change the carbon fiber hull every few dives. Or you know just figure out a different way to do this other than carbon fiber. If you mean how do you do it right, I have no idea. My layman thought was why not use a thinner titanium shell that’s then wrapped in layers of light metals or other material.

>>16703040
Thanks idiot, we already knew this. OP is asking how you would actually design the titan to not implode.

>>16703059
They actually did this, but they ignored their own equipment they designed in house to do this exact thing.

>>16703035 (OP)
by following the regulations. he was a true example of why they say safety regulations are written in blood.

>>16703035 (OP)
you make the pressure vessel a titanium sphere

Carbon fiber is a meme. If it were truly strong and stable, it would be common in nature. Hell, animals probably would have evolved carbon fiber skin and bones.

Just fake it again. The more i see that stupid threads about an obvious fraud the more i think the titanic conspiracy is right and there is no wreck at all.

for me, it's doing proper stress analysis of composite materials in CATIA, then checking hydrostatic equilibrium in ansys. after that, develop a scale model that validates the design in a hyperbaric chamber. take the data to reiterate your design and simulation model. even after all that, you'd still only use a drone sub to go down that far honestly. i'm pretty sure there's too much certification you'd need to accomplish for human habitation below sea level.

>>16707688
Material choice is 90% of it, dumbfuck.
The shape of it was more-or-less fine; cylinders resist pressure.

>>16708242
You're saying you need more to tell it to go up?

>>16703035 (OP)
Dont fucking use carbon fiber or material thats not even rated for it

>>16703035 (OP)
Use a robot. The only reason to send people down there is dickwaving.

>>16703035 (OP)
I don't normally speak in such absolutist terms,
but
just build one that isn't total shit.

>>16703035 (OP)
remotely or autonomously control it. Dive it until failure. Slather it with censors and a retrievable black box so you can see where it failed first.

I would hold my hands out against the sides of the sub. I would press outward to stop it from imploding.

>>16703040
But that's the gimmick. Otherwise, it's just another run of the mill sub.

>>16707609
>we should publicly fund science
I don't disagree, but that's not the problem here. OceanGate was never a science company to begin with. They were an underwater tourism enterprise from day one. They weren't building submersibles for deep sea studies or working on novel designs for underwater structures for any research purposes. Their business model and their designs consisted on making vessels that could comfortably fit the largest possible number of people with no technical knowledge or operational role and allow for them to enjoy the sights of the deep sea, all of that for the lowest possible cost. This difference is very clear when you compare the Titan's design and cabin to the Alvin's.
