Research Progress and Outlooks of Cryogenic Propellant Space Management Technologies

The property advantages of cryogenic propellant in space utilization as well as the challenges of cryogenic fluid management (CFM) are presented and analyzed. The characteristics of CFM technologies and their research status are discussed clearly. It is suggested that whether gravity level affecting the performance of CFM technologies should be involved in conducting the associated experimental studies. Moreover, the works of American efforts on space-based experiments of CFM technologies are reviewed, and the technical features of the used platforms and their performance are also discussed. In addition, considering the development status of the domestic aerospace and the future requirements, the probable plans on further progress of CFM technologies and space-based experimental platform are given. It is suggested that an aboard laboratory cabinet on cryogenic scientific studies and an exposed cryogenic fluid test module should be involved in the domestic space station construction to accelerate the technologies progress of CFM.
