本文将微处理机和固体线扫描摄象机联接起来,用于测定固体推进剂的燃速及其燃烧过程。此测试系统是一种新的快速光电测量装置。文中将A型和B型两种固体推进剂瞬间燃烧过程的光学图象通过CCD转为数字信号输入到微处理机中进行计算,得出乎均燃速、燃烧压力指数等。然后,用绘图仪绘出药柱长度与燃烧时间的关系图,并将上列数据列表打印、存储。 In this paper, a microprocessor and a solid line scan camera are connected to determine the burning rate of a solid propellant and its combustion process. This test system is a new fast photoelectric measuring device. In this paper, two kinds of solid propellant A and type B instantaneous combustion process of optical image through the CCD into a digital signal input to the microprocessor for calculation, obtained almost average burning rate, combustion pressure index. Then, using the plotter draw the relationship between the length of the pellet and the burning time, and print and store the above data list.
