[@michaelhill6451]

Stockton Rush didn't have some "disruptive" new technology, like he pretended. He was just willing to use a suboptimal hull shape, eat into safety margins with standard parts, use inexperienced designers (e.g. College students), and gamble his life/the lives of his passengers on using carbon fiber as the hull material, all in order to save on costs/maximize profits. If anything, this incident just shows why properly designed, tested, and certified deep sea submersibles are so expensive.

[@RoachDoggJr2112]

Additionally, it shows why capitalism has ultimately failed the human race. The reason for all of Rushs mind bogglingly stupid and evil choices were driven /solely/ by capital motives.

[@lasskinn474]

well, it's not really that the idea couldn't be of use. it's just that it might end up being really expensive to use properly(rebuild amounts) and nobodys properly tested the idea really (beyond that it does work a couple of times, which actually could be enough for some use cases, but now we wont know for a long while). you need to test everything else regardless of what you're building it out of anyway and if you'd use it for commercial you would need to devise a way to test(xray etc) or have a replacement program for the parts based on the testing same as for airplanes - and you'd need the money to do the destructive testing to be able to record the signs what the checking program would look for. doing it out of steel gets really expensive as well and would need the same program (it can also be inaccessible due to that sourcing the right alloys can end up way more complicated than one would think at fist.. politics getting involved kind of complicated).

Getting a supercar to reach 400km/h (250mph) is relatively easy. Getting to that speed SAFELY is a whole lot more difficult. Hence why the properly engineered supercars needed many years of research and testing using the best materials and the death trap kitcars and glorified tuners do it the way Stockton Rush did it - by cutting corners.

I am surprised at how many content creators continue to praise Rush and refer to the outcome as some unfortunate event as if there was no negligence. This was entirely foreseeable, let's not forget that Ocean Gate knew the vessel would not pass regulation and testing, therefore they chose not to get the Titan certified for this very reason. Furthermore, the most egregious act being the termination of engineer for trying to alert Rush and Ocean Gate that the vessel was not safe. Rather than addressing these concerns he fires him for speaking up. This is no accident, this is the result of a truly negligent CEO who ignored and silenced sound engineering advice, deliberately avoided certification and 4 innocent people lost their lives.

[@patrickvolk7031]

A side note: Stockton Rush's acoustic sensors were based on the idea of the Kaiser effect. The idea of the Kaiser effect is that as you put something under stress, as the struct compresses and pieces may rub together it will create a seismic or acoustic signal. If the load remains constant, the signal remains constant. This seems to have been observed in rock or concrete structures, as microcracks occur. The error in his practical use was, whether carbon fiber follows that, and also he never established what was the failure point. What I have seen for CF is a curve where load is compared to cycles, 20% load may allow a million cycles, while 80% may allow a hundred. This indicates that the failure of carbon fiber is progressive, the failures you're hearing aren't the old ones. He even had the observation that he heard more noise than the Kaiser effect predicted he would. Once the part has enough damaged spots, failure would increase until it got exponential. CF shatters, it absorbs enough force that it can't release it fast enough, like tempered glass. Voids would concentrate stress, and delaminations also would. Carbon fibers are a 1-d material, you can make a 2-d surface separated by epoxy, while metal crystals are 3-dimensional.

In theory Rush could have had a groundbreaking business and concept…if he did proper testing and development. He could have perfected the disposable submersible. If he could have proved and tested the unit to, let’s say 20-25 dives, reused the hemispheres and I’m sure he could have made money. If they got better then the process would become cheaper and the dives would have become more frequent. Too bad he did the cost cutting on the safety and testing part😑

[@joefish6091]

[@JasonTan-9757]

You are talking about a man who consider safety to be pure waste. It would not been possible in practice for Rush to have perfected his submersible because it would never have been safe enough for multiple usage. Moreover, he insisted on using carbon fibre, and chose not to do proper testing even when his own safety officer warn him about it. His safety officer was fired by the way for asking him to do proper testing.

[@fix0the0spade]

If the submersible has a lifespan of 25 dives then needs replacing it probably wouldn't be viable commercially. Actual DSVs have a service life that's usually measured in decades and thousands of dives. Yes that includes rebuilds but rebuilds cost a fraction of a complete new hull. For anyone who needs one for a few dives, hiring one and it's crew would make more sense than buying a 'disposable' model.

[@DemoCATicMAN]

Ha ha ha ha ha, well this one was definitely disposable. Lets face it...at these depths and pressures, it is far easier to go above the atmosphere "Outer space", then it is to go in the opposite direction. Going towards the center of anything that is going to crush you, makes little sense when our Sun gives us Nuclear Fusion that gives us all the energy that we need for our survival. We don't need to go that far beneath the surface for what we need on the surface.

[@Man_Emperor_of_Mankind]

Nah, it was screwed overall when the guy decided to use CF. Based on his statement about its strength, it's clear that the difference in the strength of CF in compression being only a fraction of it's strength in tension, was totally ignored. When in compression CF only has 1/3rd to 1/2 of the strength that it has in tension. Using CF for this application never made sense, the reduced strength and issues with pressure cycling should have stopped the project when it was just a wild idea

He was also seeking to innovate and create with other materials (I think he as a curtain maker) and risked his life. Sad for sure. What rush did would be like telling people his parachute had been tested (which it hasn’t), was made of materials which were perfect (when in fact the opposite was true) and safe (without doing any safety tests). Furthermore, going out to actively sell this idea people and get them to try his parachute by parroting those features which were blatant lies and just hoping it went well. To me, that’s evil and takes a special kind of person to have absolutely no qualms about lying to others with no regard of their safety in an attempt to “innovate”.

As usual you've brought new insights and made interesting a topic i've seen covered many times!

For this reason it works great for air tanks, pressurized aircraft hulls and such where the fibers are being pulled but not in the case of Titan where the fibers are being pushed not pullsed so the only thing providing and strength really is the resin.

[@Slider68]

A simple way to understand why carbon fiber is not a good material for compressive loads is to imagine holding a piece in your hands. When you pull on it, in tension, it is incredibly strong, significantly stronger than steel. When you push on it, in compression, it immediately buckles with almost no resistance. In compression, it is the resin that provides much of the compressive strength. Also, this buckling of fibers results in delamination between the fiber and resin layers, which further weakens the bulk material over future compressive loads.

[@themidnighttavern6784]

Carbon fiber is an excellent material for something like a car, both for high performance light weight exotics, and even things like trucks, as it's apparently holding up quite well in truck beds. But it has no place on other vehicles like a submarine. I'm stunned this proposal made it into the prototyping phase, let alone into active duty carrying passengers.

[@WJSpies]

Hubris: the man suffered from extreme hubris. Even I know (retired industrial design model maker) that carbon fiber is made from carbon threads embedded in epoxy, and it inherits only tensile strength from the fibers. By crisscrossing built up fiber ribbons in different cross directions other strength characteristics can be gained or mimicked, giving other desired properties to make very strong light structures with tensile strength and added stiffness. But under no circumstances is carbon fiber resistant to compression loads. Stockton Rush didn't even do any sort of carbon fiber crisscrossing for the pressure hull. He merely wrapped carbon fiber ribbons around the inner cylinder. There was relatively low stiffness in his vessel, and vertually zero compression strength, save what the sandwiched epoxy resin afforded it. It had almost no high compression strength. Apparently Rush thought the high strength in carbon fiber tanks, under load from compressed gases and fluids, could be applied in reverse (highly compressed pressure from the outside in). It can't that's illogical; he would ultimately know that if he understood strength of materials (1st or 2nd year mechanical engineering courses). Without that basic knowledge I must say he either didn't research how carbon fiber really works, or he was simply a vert bad engineer. I've heard his engineering prowess was highly questionable; he lost several jobs because of it.

If there vessel were able to withstand the force at depth then the rate of descent or ascent would not be a factor. On the descent the only thing that rate would possibly do is create momentum that they would need to slow before contacting the seabed.
