Abstract

A thermal resistance estimation of carbon/carbon composites used as the nozzle throat insert of solid rocket motor was performed using TPEM motor. Three types of TPEM motor and two types of propellant were employed. The ablation rate is higher for the higher chamber pressure and also higher for the higher concentration of oxidizing species in combustion gas, but it is lower for the higher material density.

고체로켓 모터의 노즐목 삽입재에 적용하는 탄소/탄소 복합재료의 열반응 특성을 분석하였다. 내열 평가 시험은 3종류의 TPEM 모터를 사용하였고, 추진제는 2종류를 사용하였다. 삭마율은 연소실 압력이 상승함에 따라, 산화몰분율이 증가함에 따라 증가하고, 소재 밀도가 증가함에 따라 감소한다.
