Study of thermal decomposition of coated oxidizer based composite solid rocket propellants

摘要

The objective of this work is to study the effect of coating of different oxidizers : normal, porous, normal coated with NC and porous ammonium perchlorate coated with NC on thermal decomposition and thermokinetic parameters of the combustion using the differential scanning calorimetry method. The first part of this study is to present the experimental procedure concerning the coating of oxidizing charges and their characterizations. The second part will be dedicated to the kinetic study of oxidizing charges. The purpose of the latter is to evaluate and determine the different kinetic parameters (the activation energy, the pre-exponential factor and the kinetic model), in order to determine thermal parameters and kinetic data (activation energy, frequency).
