摘要
对红外热像仪在在液体火箭发动机热试车过程中的温度测量进行了研究,介绍了其测量原理和工作特点,总结了在试验过程中准确测量的操作要求。结合实践,提出了一系列对试验结果定性、定量的分析方法,能够有效的对推力室壁面温度场测量结果进行处理,得到推力室工作特性的相关信息。
The study of temperature field measuring in hot firing tests for liquid rocket engine by infrared camera was presented. The measuring principle and working characteristic of infrared camera were summarized. And the operation requirement was also introduced. Practically, the measured result can be processed effectively by a series of analytic methods qualitatively and quantitatively. The method is important in investigating the characteristic of liquid rocket engine.
