摘　　要：根据固体火箭发动机羽焰特征研制了多目标多光谱高温仪。文中介绍了多光谱测温技术及测温仪系统构成。该系统可同时测量羽焰6个目标点的温度,每个目标点均有8个工作波长,可实现对发动机试验时羽焰流场轴向和环向多目标的温度动态测量。Based on the exhaust flame characteristics of solid rocket motors, a multiple target multi-spectral pyrometer was developed. The multi-spectral temperature measurement techniques and the pyrometer were introduced. The pyrometer can be used to measure simultaneously the exhaust flame temperatures of six targets positions, each of which has eight working wavelengths, and dynamic temperature measurement for axial and circumferential multiple targets of exhaust flames flow field can be carried out during the motor tests.
