| 摘 要： | 推进系统的改变会影响运载器系统性能,这时要重新安排运载器系统,使其保持在最佳状态来完成空间任务.采用类似于〔1〕的线性化质量模型,分析推导了一次性使用多级运载火箭的串联与并联推进运载器的质量方程,并运用质量方程,对推进剂非交叉供应的并联推进运载器进行了分析,求出了系统设计参数对起飞质量的影响.

| Abstract: | Vehicle system characteristics will be affected by the variations of propulsion system. It is necessary to rearrange vehicle system in order to fulfill space mission in optimal system state. In this paper the linearized mass models, similar to that in C 1], has been used to derive vehicle system mass equation for expendable, multi-stage vehicle with series or parallel propulsion system. The system mass equation has been utilized to analyze the relationship between take-off mass and design parameters for a vehicle with parallel propulsion system. |
