摘要/Abstract

摘要： 利用Ｘ射线高速实时荧屏分析（ＲＴＲ）技术对双脉冲固体火箭发动机的二次点火过程进行了内视研究。通过对ＲＴＲ图像的分析，弄清了隔板的打开模式以及塞子在一级燃烧室中的运动规律，运用图像处理技术还获得了塞子飞出隔板后的平均速度及塞子与喷管碰撞后的反弹速度，这些结果为这种新型发动机的设计提供了实验依据。

Abstract: The transient process inside dual pulse solid rocket motor during secondary firing was studied using a system of X ray real time radiography(RTR) technique The blowout pattern and the motion law of the plugs inside the first combustion chamber were found out by analyzing the RTR images By using advanced image processing techniques the mean flying velocities of the plugs after blowout and the reflection velocities of the plugs after impaction on the convergence section of the nozzle were obtained

Key words: Dual pulse solid rocket motor;RTR technique +;Secondary start
