摘要：
The flame infrared emission spectra between 4700 and 800cm(-1) of nitroguanidine solid propellant combustion were recorded using a real time, remote sensing Fourier transform infrared (FTIR) spectrometer with a spectral resolution of 2 cm(-1). The combustion flame temperature of this high intensity IR propellant combustion was studied via the fine structure of the rotational vibrational emission bands of HF (4400similar to3950cm(-1)) and HCl (2900similar to2400cm(-1)). This study yielded the flame temperatures of nitroguanidine solid propellant at different burning times. The combustion products, such as HF and HCl, were determined simultaneously and quantitatively as well. Results showed that remote sensing FTIR emission spectroscopy is a very reliable, sensitive, and rapid method for measuring propellant combustion flame temperature and product concentrations, and it could be used in combustion diagnostics for a variety of applications.
