| Popis: | In this study, the effects of porosity of the fore-catalytic bed and after-catalytic bed and preheat temperature on the decomposition and combustion characteristics of a 5 N ammonium dinitramide (ADN)-based thruster were numerically investigated in terms of the distribution of components, temperature, and pressure. The results indicated that the porosity of the fore-catalytic bed and preheating temperature significantly affected the decomposition and combustion characteristics. The porosity of the fore-catalytic bed was optimized, and the thrust performance was demonstrated to improve with increasing of porosity of the after-catalytic bed and pre-heating temperature. The results were favorable for the investigation of decomposition and combustion characteristics and could also be beneficial to the design and manufacture of different types of ADN-based thrusters. |
