Propellant Slosh

Orbital ATK customers are interested in several types of slosh:
  • Transportation slosh (tank on a train, in a boat, in a truck, etc. - 1g
  • Wind-induced pad slosh (tank on top of a launch vehicle at the launch pad) - 1g
  • Slosh during launch - rotation, spin, nutation, etc - high g.
  • Slosh while on orbit - zero g or near zero g
  • Slosh during spacecraft maneuvers with acceleration
  • Slosh in a diaphragm tank
  • Slosh in a PMD tank
  • Slosh in an empty tank (example: spinner tanks)
  • Slosh in a baffled tank (example: MESSENGER AIAA 2002-4139)
