| Abstract: | The technique situation and development tendency of upper stage propulsion system developed at home and aboard is analyzed. The multiple ignitions and long duration in orbit is required. A liquid propellant start box for turbo-pump engine is adopted to achieve multiple ignitions. A start basket propellant management device is adopted to realize propellant management in long duration of orbit. Due to these measures, the performance and flexibility of the upper stage are improved. |
