Abstract: In this paper, the combustion characteristics of thermoplastic solid propellant with burning catalyst were analyzed through the ground tests of motors.The cylindrical grains were manufactured through Polyvinyl chloride(PVC)-based thermoplastic propellants with Iron oxide(Fe 2 O 3 and FeOOH) and Copper oxide(CuO) as burning catalysts.The properties of burning catalysts were observed using XRD, BET, FE-SEM and EDS, and then the ground tests were performed to investigate the effect of burning catalysts on the burning rate.초 록 본 논문에서 연소촉매제를 적용한 열가소성 고체 추진제의 연소특성은 모터의 지상연소시험을 수행하여 분석 하였다.Cylinder 형상의 그레인은 연소속도 증가를 위한 연소촉매제로서 Iron oxide (Fe 2 O 3 and FeOOH)와 Copper oxide (CuO) 등을 적용하여 PVC 기반의 열가소성 추진제로 제작되었다.연소촉매제들의 특성들은 XRD, BET, FE-SEM 그리고 EDS 분석 등을 통해 관찰되었으며 지상연소시험은 각 연소촉매제에 따른 연소속도 영향을 조사하기 위하여 수행되었다.
