GO₂/PE 하이브리드 로켓의 추력제어를 위한 시스템 설계 및 기초실험

In this study, basic research on the thrust control by controling oxidizer mass flow rate of a GO₂/PE hybrid rocket is presented. For this purpose, hybrid rocket system including oxidizer flow control system and data acquisition system was developed. To control oxidizer mass flow rate, we used needle valve with stepping motor which was controled by LabVIEW program. During the fundamental experiments, this system managed to follow the pre-programmed (20 N - 10 N - 20 N - 0 N) thrust level.
