| Abstract: | The technique situation and development tendency of Cryogenic Upper Stage propellant management developed at home and aboard is introduced. The key technologies of liquid retention, gas-liquid separation and local thermal control of cryogenic propellants in microgravity environment are analyzed.The design of liquid oxygen Propellant Management Device was carried out, and the key functions such as Propellant Refillable Reservoir filling and Bottom Screen Plategas exhaust at designated position were verified by experiment, and the feasibility of the design was confirmed. |
