Submarine: ballast, buoyancy and depth

Flood or empty the ballast tanks and balance buoyancy, diving planes and propulsion in a water-column cutaway.

Actual application image

Try this

Set ballast below or above 20 tonnes. Diving planes become effective once the boat gains speed.

Lumped buoyancy and quadratic drag with a prescribed hull volume. Depth is visually compressed; no hull compression, ocean currents or propeller CFD.

Equations used in the module

Equations
F_b = rho g V
p = p_0 + rho g h

Engineering

Sight a star, measure its altitude and rotate a brass sky map to recover local sidereal time. Compare a matching latitude plate with the wrong plate.

Punched cards choose which warp threads rise. Follow the shuttle and see each pick become part of the woven pattern.
