| Abstract: |
| In this paper, the worldwide development history of Hydrogen/Oxygen rocket engine is reviewed. The development rules are summarized, The status and gap of domestic Hydrogen/Oxygen rocket engine is pointed out. Combined with the application demand of Chinese heavy lunch vehicle, the present technical status, and the development goal for powerful nation in space, the large-thrust staged combustion cycle Hydrogen/Oxygen engine is the appropriate choice. In addition, the technical parameters of a 220-ton staged combustion cycle Hydrogen/Oxygen engine are given out. The future development prospects are put forward. |
