摘　　要：对逐渐注水冷却与集中注水冷却燃气蒸汽式发射动力系统进行了研究,着重分析不同注水方式下发射动力系统结构的差异、注水的特点及其对发射内弹道性能的影响,在此基础上开发出一套用于预估和比较不同注水方式下发射系统内弹道性能的系统化程序。计算结果显示,不同注水方式下导弹在发射筒内运动加速度、速度、位移随时间变化的规律和发射筒内工质气体状态参数随时间变化的规律,为燃气蒸汽式发射系统的设计和方案选择提供参考依据。The gas and steam launching power systems in continuous water injection mode and centralized water injection mode were investigated. Structure difference of systems, characteristics of water injection and the effects of water injection modes on internal ballistic properties were analyzed. Based on the analytical results, a set of systematic program was developed to predict and compare the internal ballistic properties of systems in different water injection modes. The calculation results indicate the change laws of acceleration, velocity and displacement of missile vs time, and medium gas state parameters vs time in the launching tube. The results can provide a reference to design and scheme selection of gas and steam launching systems.
