Combustion simulation analysis of solid propellant sucrose/potassium nitrate for rocket engine / Análise da simulação de combustão do propelente sólido nitrato de potássio/açúcar para motor foguete

George Stephane Queiroz de Oliveira, Rene Francisco Boschi Gonçalves


This work presents detail of the process of a solid fuel rocket engine, from the initial hypotheses based on rocket engines with similar characteristics is shown uses simulation software to predict the performance of a solid rocket propellant, where the temperature of combustion products and the products generated by the combustion of propellant based on potassium nitrate and (KNSu) in which it is the product of the reaction of potassium nitrate (KNO3)/sucrose (C12H22O11) were evaluated. The results showed that the values of characteristic exhaust velocity and combustion temperature obtained for the simulation of propellant burning are in agreement with the values found in the literature,  The products of the KNSu burning reaction are mostly carbon dioxide, carbon monoxide and water. The simulation used to predict solid rocket propellant performance is a safe and feasible alternative for developing rocket motors.
