You happen to have [Lucky You..] a Real Naval Architect { yup! :-) } on the
mailing list. A few things i've done RE putting things that float and sink i
into my trav campaigns...
For subs; use a rule of thumb that the operating depth [rated] equals ten m
meters per armour rating of the vehicle hull. This corresponds nicely with real
life if anyone works out the numbers for real-life subs. All subs have to be
streamlined; if someoen were to make one an Airframe i'd give it some boost
to speed [ x1.25 maybe? ]. Design the hull like a starship. The max depth
[where ref gets to implode his players :-) ] should be about 1.5 times the
safe depth.
For MHD drives; i would have the following design strategy: Since the MHD is
a bunch of magnets and wiring, it somewhat resembles a Fusion plant of equal
tech level. Thus, a MHD drive would be some factor times the weight of a
equivalent output fusion drive...maybe 0.5 the mass and volume and cost. Or
perhaps equal to, it depends; im not a MHD expert.
Speed is a toughie. try the following:
Velocity in knots [*1.6=km/h] equals sqrt{ [Pwr(mw)*190]/[sqrt(kl)] }
[if i erred in that let me know. it's a really rough approxomation of real
sub velocity vs. power.]
All subs should be cylinders. One thats a sphere is OK but ought to have 1/3
the rated speed.
...just some more miscelaneous ramblings from
