Ballast and platform tilt

Connect ballast redistribution to changes in platform roll and pitch, from planned tank fills to the resulting motion.

How does redistributing ballast change platform tilt?

What you can model

Four initially half-full tanks move toward planned fill levels on a supported Spar. The allocation diagram shows where the ballast sits and how its distribution affects platform pose. Prescribed fill histories change the liquid weight, allowing the mechanical response to determine heel and trim.

What you can explore

Follow each tank fill and compare requested roll and pitch with the resulting angles. The error traces show how closely the platform reaches the planned attitude as the weight shifts. These views connect ballast allocation to the motion produced over the full maneuver.
