3차원 추진제 형상을 고려한 고체 로켓 모터 1차원 해석 연구

The performance of the solid rocket motor is calculated using the internal ballistics analysis. the multi-dimensional internal ballistics analysis has been needed for calculation of the performance considering the high pressure-temperature flow and the complicated grain configuration. In this study, the performance analysis program of the solid rocket motor has been developed using the 1-D internal ballistics analysis module and the 3-D grain burn-back analysis module. The developed program has been proven for the performance analysis of the solid rocket motor.
