3축 추력기의 동적 특성 연구

Dynamic performance modelling and firing test were performed to evaluate internal ballistic performance and to verify dynamic seal design by firing test of 3-axis pintle thruster motor. Dynamic performance modelling results compared to test results and verified. Although dynamic performance modelling results are not fully agreed with test results, performance prediction according to pintle movement and control possibility were ascertained by this study. Also, dynamic seal design was verified.
