A numerical analysis was conducted to investigate the effect of monopropellant injection velocity on the position of the maximum interstitial gas temperature front in the combustion chamber of a low-thrust thermocatalytic liquid-propellant rocket engine using phase portrait techniques. Quantitative maps of the front position and qualitative stability maps were obtained for homogeneous porous beds with different porosities. The parameters varied in the study include bed porosity, the initial bed temperature at the moment of engine start, and the fuel injection velocity into the combustion chamber. A regression model was developed to predict the front position, and the model was subsequently analyzed. Recommendations were formulated to ensure stable operation of the engine with a homogeneous catalytic bed.
