EVA to titanic

[ascan1984]

I was just watching a documentary about the titanic and i had just had a thought. Could you not use an EMU to visit the titanic? AKA would the suit hold at that depth.

><i>would the suit hold at that depth.</i><p><b>NO!</b> Spacesuits are designed to hold pressure <i>in</i>, deep sea diving suits have to keep pressure <i>out</i>. An EMU suit would be less than useless as a diving setup.</p>

I don't think those things can swim very well anyway, feathers get a little weighted down. <img src="/images/icons/wink.gif" /> <div class="Discussion_UserSignature"> <p> </p><p> </p><p> </p><p> <br /><table cellpadding="0" cellspacing="0" style="width:271px;background-color:#FFF;border:1pxsolid#999"><tr><td colspan="2"><div style="height:35px"><img src="http://banners.wunderground.com/weathersticker/htmlSticker1/language/www/US/MT/Three_Forks.gif" alt="" height="35" width="271" style="border:0px" /></div>

There are Newt-Suits that look, superficially, like thick, sort-of space suits that are used for underwater work - but they are effectively a "submarine-in-a-suit", hardly a space suit, and I don't think they can approach the Titanic's depth - about 12,000 feet....<br /><br />Wayne <div class="Discussion_UserSignature"> <p>"1) Give no quarter; 2) Take no prisoners; 3) Sink everything."  Admiral Jackie Fisher</p> </div>

Yup. If you're going deeper than about 300 feet you have to use a rigid suit. As you know, the pressure increases as you go deeper. In order to avoid being crushed either the pressure inside (your body or a submarine) has to be the same as the pressure outside or you have to build a pressure vessel to withstand the crush force.<p>Down to about 300 feet you can use a soft suit and a high-pressure breathing aparatus, but the lungs can only stand so much pressure. If you tried going much deeper, the capillaries in the lungs would all burst. I <i>think</i> that using a special breathing mix it's possible for professional divers to go as deep as 400 feet, but that's a <b>very</b> dangerous occupation.</p>

Here is a page with info / pics on the Newt Suits. The joints are interesting - rotating in such a way as to give pretty effective range of motion:<br /><br />http://www.sub-find.com/newt_suit.htm<br /><br />Wayne <div class="Discussion_UserSignature"> <p>"1) Give no quarter; 2) Take no prisoners; 3) Sink everything."  Admiral Jackie Fisher</p> </div>

I don't know of any suit--hard or soft--that can work at more than 1000-2000 feet.<br /><br />In any event, walking on the Titanic would be a hazardous experience, as the ship's superstructure is on its last legs.

Not just the superstructure, looks like the hull is weakening too.<br /><br />Ironically, the Brittanic, in much shallower water seems to be in significantly better shape...<br /><br />Wayne <div class="Discussion_UserSignature"> <p>"1) Give no quarter; 2) Take no prisoners; 3) Sink everything."  Admiral Jackie Fisher</p> </div>

One of the blends is Heliox, there is another which I dis-remember. <div class="Discussion_UserSignature"> </div>

Trimix, is another blend but you need vaiouse gasses in variing combinations to got safely from ~40 to 100m and the record stands at around 308m!<br /><br />From: http://www.techdiver.ws/trimix_eng.shtml
