Re: [PSUBS-MAILIST] Re Variable Ballast Calculations



Rick,

I had read in the NAVPERS manual for fleet boats, that a submarine does precisely that to submerge, (reduce displacement by flooding the tanks).

As for practicality, well this is all just math for now. Incidentally, I am not using terms correctly in these posts, ie hard, variable, soft ballast.

 

Thanks

Joe

    you dont reduce displacement by adding water. displacement = the total volume of all non free flooding  spaces.
 
the introduction of large internal ballast tanks  creates a sinificant engineering problem and a possible piont of flooding for the passenger spaces. most hard tanks are hard to inspect for corrosion. not to try to rain on your parade, the kiss pricipal seems to be the way to go here, if you ever want to get in the water.
