초록

본 논문에서는 HTPB/AP/Al계 추진제의 성능 개선을 위한 연소속도와 압력지수를 제어하기 위하여 연소특성에 관한 AP입자 사이즈 비율과 연소촉매로 사용된 Butacene 함량의 영향을 조사하였다. 23%의 $28{\mu}m$ Al과 3%의 Butacene을 포함하는 추진제 조성에서 연소속도와 압력지수는 $9{\mu}m$ AP 입자의 함량이 증가함에 따라 증가하였다. 그리고 Butacene을 함유하는 추진제는 비교적 낮은 압력지수 특성을 보임으로써 Butacene의 함량이 증가함에 따라 연소속도도 증가하였다. 그러나 Butacene의 함량에 의한 압력지수의 변화는 크게 나타나지 않았다.

In this paper, in order to control the burning rate and pressure exponent of HTPB/AP/Al based propellant for the improvement of performance, the effect of the size ratio of AP particles and various contents of Butacene as burning catalyst on combustion properties was investigated. In the propellant formulation with both $28{\mu}m$ Al of 23% and Butacene of 3%, the burning rate and pressure exponent were increased with increasing the contents of $9{\mu}m$ AP particles. And the burning rate was increased with increasing the contents of Butacene with showing the relatively low pressure exponent in the propellant containing Butacene. However, the significant variations of pressure exponent by contents of Butacene were not observed.
