초록

가스발생기의 고 효율화를 위해 고에너지 물질인 보론을 사용한 보론 비드의 비드 입도 및 성분에 따른 연소특성을 조사하였다. 본 연구는 전기적으로 가열 된 텅스텐 시트와 가시화된 전기로를 사용하여 각각 점화온도와 연소 시간을 측정하고, 고속 카메라로 연소 과정을 측정하였다. 실험 결과 점화 온도는 720~800 K 이며, 연소 시간은 보론 비드 직경에 비례하는 것으로 관찰 되었다. 온도와 복사강도 측정값을 사용하여 보론 입자의 점화 지연시간이 존재한다는 것을 확인하였고, 이를 통해 보론 비드의 전반적인 연소 메커니즘을 이해할 수 있었다.

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.
