Study on the thermal decomposition of NEPE propellant(IV)

The fast thermolysis reaction cell (gas reaction cell) in-situ with rapid-scan fourier transform infrared spectroscopy (RSFT-IR), and combined solid reaction cell in-situ and RSFT-IR technique were used to measure the gas products and condensed phase products of the thermal decomposition of NEPE propellant with and without burning rate catalyst in real time. Under linear temperature increment condition, the thermal decomposition characteristics of two kinds of propellant were studied. On the basis of obtained results, the effects of aluminium powder and burning rate catalyst of PbCO(3) to the thermal decomposition characteristics of NEPE propellant are discussed.
