How to Determine Why the Titan Imploded (a lead in)

Yeah - the mass media and many of the "media experts" were all running around like headless chickens... I just thought I'd kill the bullshit and wade into the issue.... At least this way it can be determined whether it was the window or the carbon fiber tube gave way.... and if it was the window - mostly case closed and if it was the tube, was it the glue line and or was it the tube it's self..... Maybe there is fuck all left of the tube or maybe there is some chunks of it laying around ...... Time will tell and clearer answers might be forthcoming from the wreckage....

There was also an interesting issue raised which comes from cavitation around propellors in water (and similar things) in that if the water screw if driven fast enough and the angle of twist (turns per meter) is high enough, then the water pressure on the pull side, can drop below the vaporisation pressure of the water and you get nice little "vacuum bubbles" forming - and when the bubbles collapse in, they get an extremely hot centerpoint from the compressive shock wave, and this tiny little super hot explosive blast, erodes the propellor..... well someone raised the issue that when the submarine imploded, at that depth and at those pressures - essentially when it all met in the middle of the collapse - it was like the surface of the sun for a moment, then you get the shockwave reflecting back out and then back in and so on and so forth - which would explain the sinosuidal wave of the accoustic signature. I'd imagine that the rise in energy would be instaneous and the graphic / plot and sound would be something like these. https://www.pond5.com/sound-ef....fects/item/56903682- /// https://www.pond5.com/sound-ef....fects/item/56612977-

@Life_N_Times_of_Shane_T_Hanson: cavitation does not effect smalls subs, they do not have large enough propellers for that... however ocean currents can have an effect on a small sub, and if it is a PoS like titan then it can cause massive stress to breaking on any imperfections or cracks...

@sbseed: from my understanding anyways, the impeller or propeller would have to have some SERIOUS defects (being that small) in order to cause any damage to the small sub, and cavitation itself would still not be an issue. also they usually have rubber gaskets on the connections to lessen any of those types of malfunctions, did not look like they even had that on titan...

@sbseed: We have a misunderstanding - the issue of cavitation - being the water on the suction side of the water screw, drops below vaporisation pressure (low pressure boiling point) and when the pressure rises again - the vapour bubble collapses in and all that energy of the collapse, concentrates into a spot of very high pressure and temperature and when it hits the propellor, it physically erodes the propellor. The submarine - is essentially a giant gas bubble - it's 15 psi of air inside it, and it has a wall separating it from the ocean, and the ocean has a pressure of 5100 psi around it, now the air has say a temperature of 10*C and 4 cubic meters of volume. When you compress that air suddenly to 5000 PSI, the volume suddenly gets very very small, but the heat energy of the water concentrates - so very briefly - that tiny bubble of air, reaches say 20,000*C.... Then the shockwave reflects back out and then back in and out etc... giving the distinct accoustic signature of an implosion... but as the single "bubble" collapses and then expands and collapses again etc., it begins to dissolve into the water and the big bubble breaks up into smaller and smaller bubbles and these break up into an upward rising cloud... so the implosion shockwaves diffuse and fizzle out...

@Life_N_Times_of_Shane_T_Hanson: cavitation is cause from the bubble bursting against the propeller... it is simple, and yes that is what i was talking about vs other issues... small mini-sub propellers/impellers do not have issues with cavitation being my point and they have stabilizers (remembered the proper word here)

@sbseed: The link between cavitation and the submarine imploding - is that it creates the same effect inside the bubble when it collapses. only with the submarine - the pressure was 5100 psi, and not 16 psi.... So there for the temperature inside the core of the collapsed bubble would have been hotter than the sun.
