초록

본 연구에서는 침식연소를 고려한 내탄도 프로그램을 이용하여 침식연소 모델에 따른 해석결과를 비교하였다. 동일한 추진제를 적용한 이형 그레인 형상을 적용한 추진기관의 연소 시 연소실 압력 변화를 비교 분석하여 연소가스의 유량 변화에 따른 침식연소 경향성 변화를 고찰 하였다. 고찰 결과 연소 면적이 클수록 연소실 단면적이 작을수록 침식연소 경향이 증가함을 알 수 있었다.

Two erosive burning models were applied to compare analysis results of ballistic for the internal ballistics of solid rocket motors. By comparing motor tests with results of analysis, the variance of a grain shape was analyzed and coefficients of erosive burning were drawn. Results of comparison presents that the coefficient of erosive burning was proportional to the change of burning area, while inversely proportional to the change of cross area.
