Abstract
The propellant tank of the Lunar soft-landing explorer adopts lateral symmetry dispersible layout, and the effects of the layout on the liquid propellant sloshing were analyzed. Liquid in the tank was considered as the first-order spring mass model, and the dynamics model of Lunar soft-landing explorer including propellant shake was established by using virtual power principle and the dynamics model was applicable from the dynamics descending stage to the landing stage. Finally, the dynamics simulation of descending stage was made and the simulation results can provide theory reference for explorer control system design.
