Research on Surface Tension Tank Technology of Aerospace Cryogenic Propellant

Abstract

This paper briefly introduces the research progress of long-term on-orbit storage and supply technology of cryogenic propellant, analyzes the task characteristics, sorts out the technical difficulties, and puts forward the key technologies. The passive thermal protection technology, active heat transfer technology, Vapor cooled shields technology, thermodynamic vent system technology, pressure control technology, liquid mixing technology and adiabatic support technology are described respectively, which provides a reference for the research of space low temperature storage and supply technology.
