摘　　要：对恒压式姿控发动机增压气体的绝热节流特性进行了理论分析。结合工程实例 ,分析和计算了氮气增压过程中的结构降温、膨胀降温和节流降温。综合计算结果和实际情况 ,对增压气体采取了相应的措施。由飞行遥测数据可知 。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.
