Investigation of Propellant Sloshing and Zero Gravity Equilibrium for the Orion Service Module Propellant Tanks
Abstract
We study fluid slosh in the Orion Service Module propellant tanks. Resonant slosh
frequencies were measured as a function of tank fill-fraction in a scaled model of the
tanks. We carry out both computational and theoretical calculations of resonant slosh
frequencies, and nd reasonable agreement between experiment and prediction. We
measured fluid slosh in 2-g, 1-g, Martian gravity (1/3 g) and lunar gravity (1/6 g). Using
the software FLOW-3D, we established free-surface configurations in zero gravity of
both the model and the full scale Orion SM tank. In addition, we measured formation
times of the equilibrium free surface configuration. FLOW-3D calculations suggest
that the zero-g free surface configuration consists of two separated
fluid volumes.
