Coupling of sloshing dynamics within a partially filled rotating dewar of superfluid helium II with orbit dynamics is investigated in response to lateral impulse. The study considers such points as how the rotating bubble of superfluid helium II reacts to the impulse in microgravity, how amplitudes of the slosh reaction force and torque fluctuate with growth and decay of disturbances, how these disturbances in fluid systems coupled with orbit dynamics with various rotating speeds differ in frequencies of sloshing modes excited in terms of differences in rotating speeds and how sloshing of orbit dynamics differ with and without a baffle. The numerical computation of sloshing dynamics is based on the non-inertial frame spacecraft-bound coordinate system. Results of the simulations are illustrated.
