지상용 200N급 하이드라진 추력기 개발 및 시험

For interplanetary missions including lunar exploration, large thrust is necessary for instant acceleration and deceleration of spacecraft. As a preliminary study for these missions, KARI have performed a development of large size hydrazine monopropellant thruster ground model. A 200N hydrazine thruster ground model was designed and verified by hot firing test during this study. In this paper, the thruster design and test results will be introduced.
