Abstract

The limit values of mechanical properties(MPs) of HTPB/AP/Al Solid Propellant was reviewed according to the rocket motor development procedures and the in-process values of MPs were analyzed by the tool of Process Capability Index. Based on finding the dependency among MPs, the optimization is proposed for reducing the properties defects and for improving the rocket grain safeties.

HTPB/AP/Al 계열의 혼합형 열경화 추진제를 적용한 로켓 연구개발에 있어서의 추진제 기계물성 규격을 정하는 일련의 과정을 고찰하고, 공정지수를 통하여 추진제 제조에서의 공정관리를 분석하였다. 이를 근간으로 기계물성간의 종속성을 분석하고 최적화 물성을 제시함으로서 불량률을 제거하는 공정 안전도 향상뿐만 아니라 추진제 그레인의 구조적 안전도 상승에도 기여할 것이다.
