The Thresher radioed to the Skylark that it was undergoing some minor problems. The pieces of the submarine, which included a propeller and the sub's bow with torpedo launching tubes, had been "crushed inwards," according to Naval Captain Enrique Balbi. What exactly does happen when a submarine goes beyond its crush depth? If a submarine goes below its crush depth, its pressure will be too great for the hull to handle, causing it to break open. Its not just the high pressure, but the rapid rate of compression which would tend to exceed the maximum pressure reached when an equilibrium is reached. Most submarines are designed to be as small and tight as possible to minimize noise and maximize space, which means that there would be little room to move or even breathe. Nautilus: 1800. Reddit and its partners use cookies and similar technologies to provide you with a better experience. Search continues for the 44 crew members on board. Its generally accepted that the maximum depth (depth of implosion or collapse) is about 1.5 or 2 times deeper. Even the highest technology nuclear submarines can end up on the ocean floor if the crew isnt careful or the technology fails. I used to work in a scuba shop and the tanks would heat up quite noticeably when being filled (so wed put them in a tank of water to keep them cooler and could get more air in). 2009-06-05 02:47:05. Its like the worse flash fire ever. Same scuba shop I overfilled a tank (long story but I was not as careless as that sounds) and the pressure relief valve let go. How submarines are affected by pressure comes down to engineering, materials, and construction, but all subs maintain an internal pressure of 1 atmosphere. The pressure from the water would push in on the persons body, causing any space thats filled with air to collapse. So, the lungs would collapse. Submarine Crush Depth :06: Just saw a show about the Thresher. An underwater fart will shoot you up to the surface like a missile which can cause decompression sickness. I got in a debate with someone where I was saying that when a submarine implodes, it just fills with water in an instant, while they argued that it crushes like a soda can. If the object was previously solid, then implosion usually requires it to take on a more dense form - in effect to be more concentrated, compressed, denser, or converted into a new material that is denser than the original. Because your ear drum does not want to accelerate, it stretches like a spring in order to produce zero net force. All rights reserved. Implosion is a key part of the gravitational collapse of large stars, which can lead to the creation of supernovae, neutron stars and black holes. The latest open literature says that a US Los Angeles-class test depth is 450m (1,500 ft), suggesting a maximum depth of 675900m (2,2503,000 ft). Regarding the implosion of a submarine whose hull has ruptured, as others have stated, it is a catastrophic event. Submarine - Wikipedia Reply Thats when the outer hull finally snaps, immediately followed by the fuel and air tanks, as well as the inner hull which are not at all rated for such pressures. While modern CRTs used in televisions and computer displays have epoxy-bonded face-plates or other measures to prevent shattering of the envelope, CRTs removed from equipment must be handled carefully to avoid personal injury.[1].

When a submarine reaches its crush depth, the pressure inside the submarine reaches what the hull can handle, forcing it to open the hatch. Wiki User. As the submarine descends deeper into the sea, the pressure increases exponentially. When a submarine implodes, its hull is too weak to withstand the outside pressure. Retired navy captain James H Patton Jr said a submarine reaching crush depth, would sound like a very, very big explosion to any listening device. After that, the poor pig really was just bones. However, submarine characteristics, like any other machine, are not always desirable. The first is, well, unsafe, but not necessarily the end. Argentine navy reports an explosion near missing submarine. The technique involves the firing of precisely placed demolition charges in specific timed intervals that use gravity to cause the center of the building to fall vertically while simultaneously pulling the sides inward, a process often erroneously described as an implosion. This decreases the material's volume and thus increases its density by a factor of two to three, causing it to reach critical mass and create a nuclear explosion. The average depth of the worlds oceans is 3,790 meters, or 12,400 feet, or 2 13 miles. The first is, well, unsafe, but not necessarily the end.

So in reference to that other thread about explosions in subs and ships that sink, would the rapid compression detonate explosives on the sub (other than the depth charges with pressure triggers). When a cavitation bubble forms in a liquid (for example, by a high-speed water propeller), this bubble is typically rapidly collapsedimplodedby the surrounding liquid. however its often that submarines lose control and sink, in which case the crew would see it coming. Water is present on the outside of an ear drum, but air is present inside.
