Study on Flame Temperature Measurement of Pyrotechnic Composition Using Multi-spectral Thermometer

In order to solve the problem of flame temperature measurement of pyrotechnic composition,the principle of work of multi- spectral pyrometer and the data processing method based on second measurement are described in this paper,and the multi-spectral thermometer is produced. Take the black powder for example,the multi-spectral thermometer is used to test the radiation energy of it. And the data processing method based on second measurement is used to calculate the data to get the true temperature of black powder. Tests and studies show that the multi-spectral thermometer can be well used to measure the flame temperature of pyrotechnics,and it has high stability .This study lays a fundation for the research on combustion characteristics of pyrotechnic composition.
