There is a continued interest in hybrid propellant re-search with the aerospace industry. In this study, different formulations of paraffin based propellants were analyzed and compared from the kinetic point of view. For this, computational simulations of these reactions were performed through the ReaxFF inter-atomic interaction model, through Reactive Molecular Dynamics (RMD) simulations, which allowed the control of the temperature variable during the progress of the reaction. The analysis revealed that the addition of aluminum causes an increase in the activation energy of the reaction, which makes the reaction slower for the temperature control applied, but increases the frequency of collisions between molecules, making the hybrid propellants added with this compound more reactive at higher temperatures.
