| Abstract: | The pressurant characteristics of insulated throttling for regulated pressure feed attitude control engine are analyzed in this paper. The temperature dropping of structure, expansion and throttling are described and computed. The corresponding measures are in use on the basis of the computation result and real engineering status. The telemetry data is showed that the measures taken are effective. |
