Re: [PSUBS-MAILIST] Center of gravity Vs. Center of Bouyancy

Ray,

The Trigger trainer is a simulated submarine control room with all the
dials, wheels, switches, valves, etc. in a duplicate arrangement as the
USS Trigger sub's control room. The trainer is a major part of sub
school to teach new subbers how to drive the boat. The trainer is
computer controlled and the controller can set up disasters and other
situations that may come up while operational at sea. For example, the
stern planes hydraulics goes out suddenly. What do you do? Immediately,
you go into manual and control them manually for example.

I wish I could share a photo but I don't have one of this trainer. They
also had another trainer for flooding situations and that was very
"interesting" to experience. That was one of only two times I got scared
in subs. Again it is computer controlled and they can make pipes leak,
hulls flood with cracks, etc. and with the use of damage control
supplies such as wood blocks, plugs, band-in kits, etc., we were to
secure the flooding and leaking. My team did it after we were next high
with water in the department. Remember, the electricity is still on
also!

Much of this damage control should be considered with Psubs also. How do
you secure a leak if you are submerged? One posting (yesterday?)
mentioned a valve on the inside of a thru-hull line being required. That
should be an absolute must for all sub builders to consider and do. If
an internal valve, pipe, or control fails, how do you control the
flooding. Much like your house; if you have a supply line to the toilet
fail and the entire bathroom is flooding, how do you control or stop the
flooding? First, try the stop valve behind the toilet where the flex
line comes out of the wall. Since that valve is rarely used, it probably
won't work or it too will break when you try turning it. Next, you go to
the main line supply line outside the home where the water enters the
house. Secure that valve to turn off not only the toilet supply line but
the entire house. If that fails, most properties have a valve on the
owner's side of the meter near the street. If not, turn the meter valve
off. These are all ways to simply isolate one small water line to the
toilet and the same philosophy should be used in building subs.

As for "Harder . . . never out", this is a dig to the bubbleheads on
those boats that they are always in port and on liberty while the rest
of the boats are at sea away from their loved ones. I don't think this
is true but it was a friendly jab.
