| Outline of Final Research Achievements |
A numerical analysis clarified ignition characteristics of the chemical propulsion rocket engine (thruster) used for attitude control and orbit insertion of a spacecraft. Applicants also conducted test data acquisition necessary for verification and constructed detailed chemical reaction model required for numerical analysis. Our detailed chemical reaction model was able to build higher prediction accuracy than previous research. Also in the verification test, there was new discoveries about ignition and chemical species distribution. By conducting numerical analysis for the verification test, the detailed chemical reaction model could be validated. In the numerical simulation for the flow field inside the thruster, the flame holding mechanism and the criteria of the two combustion modes were clarified.
