箭载飞行器抛射内弹道模型研究

Dispersion Internal Ballistic Model of the Rocket-borne Vehicle

箭载飞行器抛射采用燃气活塞式抛撒方式,文中描述了箭载飞行器抛射过程,根据火炮内弹道学理论,建立了箭载飞行器抛射过程的物理数学模型,并进行数值计算,得出抛射过程经历时间、膛内气体压强随时间变化规律、最大抛射相对速度、最大过载等仿真计算结果。

In this paper, describing the dispersion process of the rocket-borne vehicle; based on the theory of internal ballistics, erecting the physical and mathematic model of the dispersion process of the rocket-borne vehicle; computing the dispersion internal ballistic equations of rocket-borne vehicle; obtaining the computing results including the time of the dispersion process, the law of the in-bore pressure along with time, the most dispersion relative velocity, the most overload, and so on.
