Abstract

Abstract

The spinning stability of a spacecraft with multiple on-axis-containers partiallyfilled with inviscid, incompressible liquids is investigated in this paper. The coupledeffect among translation, nutation of the rigid spacecraft and slosh of the liquidsis considered. Employing Galerkin's method the dynamic system is discretized andthus the dynamic equation is established in ODE form. Using Kelvin's theorem,the stability criterion is finally obtained.K0eywords: Dynamics of spacecraft, Liquid slosh, Stability theory
