The dynamic behavior of liquid propellants in launch vehicles and spacecraft has been of great importance in past current generation vehicle designs. A method to theoretically estimate the viscous dissipative force from liquid propellants transient motion in tanks is present. The estimation algorithm is combined into the LAMPS(Large AMPlitude Sloshing) algorithm, where the dissipative values have been approximated from test data. Analytical predictions show excellent correlation with existing test results.
