Abstract

In this study, AOT that is used as a surfactant in various industries was applied to an HTPB/AP solid propellant. AOT is one of the anionic surfactants, and there have been cases where AOT was reported to induce self-extinguishable properties in propellants overseas. In this study, solid propellants using AOT were prepared, and their properties and combustion characteristics were investigated. The combustion rate of the AOT-applied propellant drops sharply when the pressure reaches a certain value during combustion. Further, the density and hardness of the propellant are lower than those of conventional HTPB/AP propellants.

본 연구에서는 다양한 산업에서 계면활성제로 적용되는 AOT를 HTPB/AP 고체추진제에 적용하였다. AOT는 음이온 계면활성제 중 하나로, 해외에서는 AOT가 추진제의 소화특성을 유도한다고 보고된 사례가 있다. 본 연구에서는 이러한 AOT를 적용한 고체추진제를 제조하였고, 물성과 연소특성을 고찰하였다. AOT를 적용한 추진제는 연소 시 일정 압력에 도달하게 되면 연소속도가 급격히 떨어지는 특성을 나타내며, 물성 특성에서도 밀도와 경도가 일반 HTPB/AP 추진제에 비하여 낮게 나타난다.
