单级入轨运载器推进系统方案分析

A PROPULSION SYSTEM ANALYSIS FOR SINGLE STAGE TO ORBIT VEHICLE

选择了九种双组元和三组元发动机系统方案，计算了各种方案发动机的性能和质量。当单级入轨运载器主推进系统由这些发动机组成时，计算和分析了推进系统的组成方式对运载器干质量的影响。计算结果表明，当推进系统全部由三组元发动机组成时，运载器干质量最小。

Nine schemes of bipropallent and tripropallent engine are selected,and their performances and masses are also calculated.The effects of the propulsion system on the dry mass of the single stage to orbit vehicle are analyzed,the propulsion system being made up of these engines.The calculated results show that the vehicle with main propulsion system made up of tripropallent engines has the minimum dry mass.
