Abstract
추진제 KM10은 니트로셀룰로오스를 주원료로 제조된 단기추진제로서 장기저장 시 자연분해현상을 일으키는 것으로 알려져 있다. 따라서 본 연구에서는 고온가속노화시험과 저장분석시험을 이용하여 추진제의 저장수명을 추정하였다. 고온가속 노화시험을 이용한 저장수명추정은 Arrhenius 식과 Berthelot 식을 사용하였으며, 저장분석시험을 이용한 저장수명 예측은 1차 회귀직선식을 이용하였다. 본 연구 결과에 따르면 고온가속 노화시험의 Arrhenius 식과 Berthelot 식을 이용하여 추정한 추진제 KM10의 저장수명은 43.72년, 16.53년으로 큰 차이를 보였으며, 저장분석시험으로 이용한 저장수명은 42.94년으로 나타났다. 이것을 E. R. Bixon의 연구결과와 비교할 때 Arrhenius 식을 이용하여 추정한 값이 타당한 것으로 판단되었다.
The propellant KM10, a single propellant manufactured from nitrocellulose, was known to cause natural degradation phenomena at long term storage. In this study, the self-life was estimated using high temperature acceleration aging tests and stockpile analysis test. For the life expectancy estimation, Arrhenius equation and Berthelot equation were used in the high temperature acceleration tests, and the first order regression was used in the Stockpile analysis_x000D_
test. The self-life of propellant KM10 using the Arrhenius equation and Berthelot equation showed significantly different results as 43.73, 16.53 years in the high temperature acceleration test, and it showed 42.94 years in the Stockpile analysis test. The value of self-life predicted by Arrhenius equation was reasonable when compared with the result of E. R. Bixon.
