本文介绍了英国火箭推进研究院进行固体推进剂燃烧不稳定性研究的工作计划。 文中讨论了数据采集和处理的技术,并例举了实用发动机燃烧的不稳定性。还描述了研究不稳定性的发动机和测量在振荡压力和速度条件下固体推进剂试样的燃烧速率系统。给出一些实测结果的例子。
This article describes the work plan of the UK Rocket Propulsion Institute for the study of the instability of solid propellant combustion. The article discusses the technology of data acquisition and processing, and illustrates the instability of practical engine combustion. Also described are engines that study instability and systems that measure the combustion rate of solid propellant samples at oscillating pressure and velocity conditions. Give some examples of measured results.
