硅系延期药燃烧过程的研究

Study on Combustion Process of Silicon Type Delay Explosive

采用高速摄像技术对硅系延期药的动态燃烧过程进行了研究,计算了延期药燃烧的瞬时速度和平均速度。试验结果表明,利用高速摄像技术既可以清晰的看到延期药燃烧波阵面的传播过程,又能计算延期药燃烧速度。研究结果显示,硅系延期药在燃烧过程呈现出明显的非线形振荡燃烧特点。

Through using the high-speed digital camera technology, research is carded out on dynamic combustion process of silicon delay explosive, In addition, instantaneous velocity as well as average velocity of the combustion of silicon delay explosive is calculated. The test result shows that not only the spreading process of burning wave front can be seen clearly but also the combustion velocity of delay explosive can be reckoned by using high-speed digital camera technology. Besides, findings indicate that the combustion process of silicon delay explosive is characteristic of obvious nonlinear screeching.
