Abstract
AP 기반의 혼합형 열가소성 고체 추진제의 연소 억제 방안과 그 효과를 제시하였다. 입자 사이즈가 다른 AP를 적용한 효과와 0.5%~2.0%의 LiF가 미치는 영향을 분석하기 위해 PEBAX/AP 열가소성 고체 추진제에 대한 지상연소 시험을 통해 연소속도 및 압력 지수를 산출한 후 비교 분석하였다. 분석결과, 큰 AP 입자 사이즈를 적용하는 것과 2.0% 이내의 LiF 첨가는 연소속도를 감소시키는 효과를 보였으며 본 논문에서는 이에 대한 각각의 영향을 정량적으로 제시하였다. This study suggested techniques to reduce burning rate and their effects for the AP thermoplastic composite propellant. Burning rate obtained through ground tests using a small size motor were analyzed to investigate the effects of AP particle size and LiF of 0.5~2.0% on the inhibition reaction for the PEBAX/AP thermoplastic propellant. The results showed that utilization of large size particle of AP and addition of LiF under 2.0% can reduce the burning rate sufficiently and their quantitative effects were suggested in this paper.
