| 摘 要： | 为研究火箭发动机故障的羽流光谱诊断技术，对三级元双工况火箭发动机羽流发射光谱进行了实验测量。结果表明娄发动机有异常杂质进入羽流时，羽流光谱中有该物质的显著特征光谱；同时，正常情况下羽流辐射光谱随发动机不同结构、不同工况及不同工作参数而表现出不同的特征光谱。

| Abstract: | Based on the study of fault detection and diagnosis for the rocket engine by plume spectroscopy, the measurement of the plume radiation for the tripropellant rocket engine operating under dual-mode was conducted. The results show that the evident characteristic spectra of abnormal materials were presented while these materials were introduced into the plume. We also found that different characteristic spectra of the plume followed different rocket engine status. |
