| 摘 要： | 建立采用氮气驱动的弹射型悬挂发射装置的数学物理模型,用气体动力学理论分析了高压氮气从储气罐通过导气管道到弹射活塞腔室,驱动活塞推动悬挂物直至其完全脱离载机的整个运动过程。给出了对某型号悬挂发射装置的实例计算,讨论了不同结构参数对弹射性能的影响,为该系统的实际设计开发提供了理论依据。

| Abstract: | A numerical model of ejecting system driven by nitrogen is established.The whole process for high-pressure nitrogen from storage tank into ejecting piston chamber through pipe,driving the piston to propel suspender until it is complete disengaged from bomb hook,is analyzed with gasdynamics theory.An instance of certain bomb hook is calculated,and the effects of different parameters on ejecting performance are discussed. |
