수류시험을 통한 액체로켓 공급계 모델링 검증

초록

In this study, the mathematical modeling was validated through the hydraulic test that simulates a small-sized liquid rocket engine. To improve modeling accuracy, experimental coefficients were derived based on the theory and applied to modeling. Validation of the component unit and the system unit was performed, and the effect of the deviation of the experimental data on the validation results was analyzed through reliability evaluation. Factors influencing the accuracy of the simulation were analyzed and a method of improving the accuracy of the system analysis was proposed.
