Abstract: |
This paper reviews the supercooling loading technology of cryogenic propellant,analyzes the affect on launching capability by propellant temperature. Analysis shows that supercooling cryogenic propellant can enhance the launching synthesis performance, such as reduction of the pressizuration system scale, reduction of the tank volume and the tank wall's thick, lower difficulty of cryogenic launch vehicle precooling, and shorter time of the pre-launch propellant loading. This paper lists the main technology development path as well as key technologies. |
