Study on Thermal Decomposition of AP/HTPB Base Bleed Propellant after Depressurization and Flameout Conditions

Abstract:

In order to analyze the characteristics of secondary ignition of AP/HTPB base bleed propellant, the quenched samples of AP/HTPB base bleed propellant are made under the condition of transient depressurization, and experiments on thermal decomposition of this micro sample are carried by means of differential scanning calorimeter (DSC). The experimental results are obtained under two heating rates of 20°C/min and 40°C/min. They are analyzed and compared with the original sample of AP/HTPB. The kinetic parameters are estimated according to thermal decomposition rate equation and thermograms.
