고에너지 가스발생기용 보론 비드의 연소특성 연구

다국어 초록 (Multilingual Abstract)

The combustion characteristics of Boron-beads to improve the energy density of gas generator has been investigated in accordance with diameter of beads and their composition. In this paper, electrically heated tungsten sheet and visualized furnace are applied to measure ignition temperature and burning time of bead respectively. The results proposes ignition temperature between 720~800 K and burning time proportional to bead diameter. Also a ignition delay of boron particle is detected through the temperature and radiation intensity measurements.
