“…To solve the basic problem of interior ballistic by theoretical methods, the influence of other factors is taken into account by the experiment coefficient. The following assumptions are used to solve the interior ballistic problem of a solid-fuel rocket engine, see in [9][10][11][12]: -The igniter ignites instantaneously, then at t = 0, p = p in ; -The propellant burns according to the laws of geometry; -Static pressure does not change along the combustion chamber and is equal to the braking pressure at the nozzle outlet; -The temperature of the combustion gas in the combustion chamber T 0 does not change and is equal to:…”

“…Research [2] only focuses on determining the movement parameters of gas flow through the nozzle of a solid-fuel rocket engine. Research [4][5][6] has mainly studied thermal protection solutions for rocket engines. In addition, studies [7,8] have also mentioned the working parameters of rocket engines, however, no studies have evaluated the influence of the structural parameters of the engine on the working ability of solid-fuel rocket engines.…”

This article presents a method for building a mathematical model to determine the working parameters of a solid-fuel rocket engine. By changing some structural parameters around the initial values, the working characteristics of the rocket engine were investigated to evaluate the reliability of the designed structural parameters. The C5K solid-fuel rocket engine was selected to verify the model. The survey results show that: the volume of the combustion chamber increases by 20%, pressure decreases by 1.07%, thrust decreases by 1.07%, and engine working time increases by 2.9%. In addition, the change in critical cross-sectional diameter and the length of the propellant rod also significantly affects the thrust and working time of the engine. The results of the article are used as a theoretical basis to calculate and design rocket engines to ensure high accuracy.
