摘要
发动机高空羽流场中包含的信息非常丰富,因此羽流场的诊断对于研究发动机性能,以及羽流效应有着相当重要的作用。为了开展发动机高空羽流的仿真与试验研究,进行了相关文献研究工作。以高空羽流效应研究为背景,从羽流场测量技术出发,综述了空间模拟设备中的非接触光学诊断方法,总结得到了一些非接触光学诊断技术,分析了不同诊断方法的优劣,并对部分测量结果进行了误差分析。文献研究表明,非接触光学诊断技术在发动机羽流测量方面有着独特的优势,常见的光谱法及激光诱导荧光等方法还可以对羽流的组分、浓度、分布、温度、速度等进行研究,从测量技术的发展来看,非接触光学诊断技术将成为高空羽流场测量的主导。
There is much information in the plume of high altitude rocket motors. The diagnosis of the plume is of great significance to the research of both motor performance and plume effects. Based on literature study, several non- intrusive optics diagnosis means and technologies are summarized, and the advantages and disadvantages of these means are analyzed. Literature study result shows that there are obvious advantages in the measurement of high altitude plume by applying optics diagnosis technology. Some major diagnosis means, such as spectroscopy and Laser-induced fluorescence （LIF） might be used to study the species, density, distribution, temperature, and velocity of the plume. The non-intrusive optics diagnosis will be the leading technology in high altitude plume measurement in the future.
