[tec] "bouyancy problem"

Redlance88 · 04-06-10, 01:46 AM

I understand it that at a depth below 250m or so it is very difficult to keep the sub from going to the bottom for good. Basically flank speed to maintain that depth or sink further and crush. My question is this, is this a bug or is this the way that they worked then. it's not as simple a question as it may seem. as a scuba diver, I know that near the surface one often has to add weight just to be able to stay underwater, but as you go deeper , you have to keep adding air to a Buoyancy control device to keep control of your depth and to keep from rapidly sinking. to me this sounds like the same thing is happening to the subs, and here is the kicker, after a certain depth there is no more volume for the trim tanks to keep the sub at the ordered depth , to to maintain depth you need up force from the dive plains. just like on the surface you need negative on the plains to force the sub underwater. ( I think ya can still dive a u-boat without them, but it would take a bit longer) the depths that this sort of effect would happen may be all wrong, but just thinking before it is (fixed) make sure it needs fixing.
I welcome comments from any more in the know than I.
