Combustion Characteristics of HTPB/AP/Zr Propellant
HTPB/AP/Zr 추진제의 연소 특성

Abstract
Zirconium(Zr) addition to formulation of HTPB/AP propellants, was shown to be less specific impulse than aluminum(Al) by the theoretical calculation because of the lower flame temperature and higher molecular weight of Zr oxide. It was found that the burning rate was faster with the finer size of Zr and the more content of
HTPB/AP의 성능을 이론적 계산에 의해 분석한 결과, Zr 함유 추진제는 Al 추진제보다 비추력이 낮은데 그 이유는 화염온도가 낮고, Zr 산화물의 분자량이 크기 때문이었다. HTPB/AP/Zr 추진제에서 Zr의 입도가 작을수록 연소속도가 증가하며, 입도가 작은
