摘　　要：针对水平蒸汽发射系统各组成部分参数相互耦合的问题,应用变质量热力学理论,建立了水平蒸汽发射系统各组成部分的动态数学模型,并对系统的发射过程进行了动态仿真,分别得到了3种不同类型发射阀下的流量系数与载荷无量纲速度随无量纲位移变化曲线之间的对应关系,在此基础上,对系统发射性能进行了分析和优化设计,进而得到了优化后3种不同类型发射阀的流量系数及系统相关参数之间的关系,为系统的设计和试验提供了理论指导。Focusing on the intercoupling of the parameters of each component of the horizontal steam-launching sys-tem, and based on the variable-mass thermodynamic theory, the dynamic mathematical model for each component of the system was established. In addition, a dynamic simulation of the launching process of the system was conduc-ted and the corresponding relations between the flow coefficient, and the load dimensionless velocity and the dimen-sionless displacement variation curve under three kinds of different launching valves were respectively attained. On this basis, the performance of the system was analyzed and the optimal design of the system was carried out. Subse-quently , the relations between the flow coefficient and the correlative parameters of the system under the three kinds of different launching valves were acquired. The results provide a theoretical guidance for the design and experiment of the system.
