I'm not a submariner but I believe that much of the time they are heavier then water at the depth they are navigating and have a positive angle on the planes to maintain depth. A modern military submarine tries to be as close to neutral buoyancy as possible. But since exact neutral buoyancy is impossible, they usually try to stay ever so slightly positive so that if something happens and they lose control, they'll rise instead of sink. Static uncontrolled rising and sinking is a positive feedback loop in that as it sinks, the pressure goes up, the hull compresses and takes up less water volume, becomes less buoyant, and the rate of sinking becomes faster and faster. Not good. If it's initially positive buoyant, as it rises, the rate of ascent becomes faster and faster. Not nearly as bad as sinking faster and faster. Steve |
