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.
