Satellite Surface Tension Tank Design

It's the most important step for the design of propellant management device to design a surface tension tank for satellite . In this paper , the characteristics and usual use of the components were analyzed.The systematic design of channel was presented -starting from screen area analysis in worst operating condition , proceeding into the pressure network analysis , ending with optimization design . The number of the channels was chosen, both the relationship between the channel wide and the minimum screen area covered by the pool and the relationship between the location of the pool and the covered screen area were presented by analyzing the screen area covered by the liquid pool under the worst operating condition . The optimization design was carried out under the minimum mass requirement, the minimum mass were analyzed , both the relation between dimension and mass were presented .All areas of concern inherent in the vanes surface tension tank design was addressed , includes determination of surface position , steady and unsteady flow analysis and the sponge configuration choice and performance analysis .The neutral buoyancy test was introduced in this paper , the unsteady flow analysis was presented.
