Combustion simulation of hydroxyl-terminated liquid polybutadiene, ammonium perchlorate and aluminum in composite solid propellant formulations.

Resumo

© 2019 Sociedade Brasileira de Quimica. All rights reserved.The present work presents combustion simulations of hydroxyl-terminated liquid polybutadiene loaded with ammonium perchlorate and aluminum, using Chemkin software and the “Plug Flow” type reactor. These materials are widely used in solid composite propellant formulations. Through this study, the effect of parameters of axial velocity, equivalence ratio, pressure and temperature during the firing of the propellant were discussed. The objective of this work was to discuss how to define the best parameter value based on the obtained results, and thus generate optimized formulations.
