파열판을 장착한 하이브리드 로켓의 수중 점화 특성

In this study, underwater combustion test was performed to analyze the ignition characteristics of a hybrid underwater propulsion system in the presence of a rupture disc. LN2O and HDPE were used as oxidizer and solid fuel respectively, while the KNSB propellant was used as the ignition source. As a results, it was found that the burst of the rupture disc by the ignition source, prior to the main combustion, had a minor effect on the operability of the underwater propulsion system.
