I saw a guy prang his carbon fiber glider from about 350 agl. Stalled, dropped one wing and went in nose down. Seat separated and he broke both ankles and smashed his lower jaw. The front of the glider looked like a smashed egg with little pieces scattered around. Shattered.

An aluminum airplane would have crumpled like a beer can absorbing energy. A CF pressure hull doesn't seem like a good idea. The applications involved are apples and oranges but it seems iffy.

Debris field being evaluated

A debris field was discovered within the search area by an ROV near the Titanic. Experts within the unified command are evaluating the information," the Coast Guard wrote on Twitter.

Pretty sure they found the Titanic debris field in 1985.

Proven?

You mean exact replicas were cycle tested to 6000 psi repeatedly and subjected to non-destructive inspection ( xrayed ) looking for premature fractures,  failure points and deformations after each 10 hour drive to 12,500 , inspected for corrosion and wear points and then repeatedly cycled in and out of the pressure environment to determine cycles till failure?

That type of proven or that they just used it a few times before and hoped for the best.

Do they even have an inspection protocol after each dive?

Since they found the debris it would be nice to know if the porthole window on the end cap that was rated to only 1300 meters failed or was it the carbon fiber hull.    My guess is the hull failed.   I dont think carbon fiber is all that great of a material to use to withstand repeated trips to that pressure.  I know even if i had that kind of money, i would never be caught going to those depths in a vehicle like that.

They used it to failure and got their maximum moneys worth out of it.

they had 5 subs, now 4.

They made 13 dives to the Titanic, I don't know how many this particular sub did.

maybe they should keep using the other 4 and find out what the mean time to failure is.

as far as safety stuff goes the bare minimum standard is 3X work rating. I am not exactly sure how you calculate orders of magnitude for pressure but the thing should have been rated for a hell of a lot more than it took to grenade it.  I didnt know they had 5 subs. why go so cheap and build 5 when you could build 2 that wouldn't kill you?

Because they did no engineering testing on a novel approach with novel materials at 6000 psi. The pressure vessel was glued together FFS.

They did no cycles testing, no xraying for changes in the craft after each or any dives.

It was reckless and the CEO was not the only person to die or be affected by the criminal negligence.

yes, but that was a small vessel that produced a probably very short impulse when it imploded.

I am surprised they admitted to the sensitivity  and ability of the system.

And they didn't know it was going to happen ahead of time.

Numerous industry experts had raised concerns about the safety of the vessel. OceanGate executives, including its CEO Stockton Rush (one of the fatalities in the implosion), had not sought certification for Titan, arguing that excessive safety protocols hindered innovation.

I mean it's certainly possible. 1" cable has a minimum break strength of over 100k lbs. That's 5x the weight of the sub, but keep in mind that displacement is attributed to the sub buoyancy (everything weighs less in water).

Granted you'd need a big ship certainly. But high risk operations like this...you'd think that would be a thing.

I guess at the end of the day it's an easy corner to cut.

The math doesn't add up on incineration. Maybe mild burning but I'm not even sure skin can burn that fast. I can slip my hand through 2,000 degree flames briefly and barely feel warmth. In the millisecond or so it took for the implosion to happen  I don't even think 10,000 degrees is enough to cause burns before the cold water hit.

You would probably need 5 miles of line and who knows how strong to lift a 20,000 lbs submersible. You can even properly use 100lb fishing line 300-400’ deep because of the pressure of the water and current.

With the amount of line out a few miles the pressure would enormous.. … It doesn’t seem possible.

Ideal Gas law (you left out the ideal part) says the air temperature increased if the air was within a closed system, no energy was absorbed by surroundings, there was nothing except air inside the space, etc. But that'snot the reality so Odeal gas law isn'tdirectly applicable. Did the air temperature increase? Most definitely, the math done by another poster (I quoted it below bc I'm too lazy to do the math) says it could reach a bit north of 2,000 degress assuming it was perfectly compressed before the air mixed with the water and it was cooled. Even if we assume that's what happened that doesn't equal incineration. Build a nice big camp fire, get it hot, then very quickly wave your hand through the flames. You won't even singe the hair on your hand (assuming you're a man and have some hair on your hands). The math says the implosion of a sub at that depth takes approximately a millisecond. Your hand is in the flames as you wave it through the fire for a minimum of 25 milliseconds (actual time depends on how quickly you wave it through).

Nobody was incinerated, they were crushed. Depending on how the hull failed they may have been crushed flat by debris, possibly "shredded" by debris or turbulent water and the other bodies being slammed together, or they could have been somewhat equally compressed simply by application of equal pressure all around. Reality is that it was probably a mix of all those with quite a bit of the blender effect with a good dose of being crushed between pieces of debris.

It would take a millisecond for a 20 meter wide sub at 1,250 feet.  This sub was less than 2 meters wide, and at 10 times the depth.  Implosion took very much less than a milisecond,  probably hundreths of a milisecond.

I fully believe the rise in temperature.  But my question is, does that temperature last long enough for complete incineration?

at 375 atmospheres and temps north of 2000C?  Maybe.

Saw one video on Youtube that claimed 10,000*.

how did that work out for them?

The vessel imploded on the 5th dive?

Is that the measure of success?

maybe airlines should adopt that level of success with their transport vehicles.

RIP

The number of comments here making light of, or downright celebrating this loss of life is disgusting.

Those people had the balls to follow their dreams, and push boundaries not many other people do.

I wouldn’t call them heroes, but they damn sure had the qualities that we need in men today.

Hopefully some will learn from this, and push forward on the project.


So,  you don't allow for the possibility that people can be flat out stupid taking chances with their own lives?

I don't think I would have trusted my fate to a homemade submarine with a waiver that mentions death several times on the first page.


The sub was proven. They also had access to all of the controversial information. It was risky for sure, but I wouldn’t call it stupid.


Proven?

You mean exact replicas were cycle tested to 6000 psi repeatedly and subjected to non-destructive inspection ( xrayed ) looking for premature fractures,  failure points and deformations after each 10 hour drive to 12,500 , inspected for corrosion and wear points and then repeatedly cycled in and out of the pressure environment to determine cycles till failure?

That type of proven or that they just used it a few times before and hoped for the best.

Do they even have an inspection protocol after each dive?


4 trips without an issue. Proof that the construction was solid. Longevity is another issue. Obviously.


that doesnt prove anything except incompetance

the construction was obviously not solid it was flawed by material choice


It was proof enough for those that knowingly went down.

Can you imagine if cars were deemed perfectly well engineered as long as they could do your work commute at least four times before violently and catastrophically failing?

But I guess we all know the risks of driving.
