Low erosion high-energy propellant is one of the research directions to extend weapon's life and improve capability. In this study, energetic propellants containing different corrosion inhibitors were designed prepared. Close bomb tests semi-confined experiments used investigate burning properties propellants. The mechanism erosion-reducing titanium dioxide (TiO2), talc, octaphenylsilsesquioxane (OPS) on was comparatively analyzed. results show that OPS has lowest rate longest time, a minimized loss fire force, with best effect explosion heat reduction. reduction efficiency twice TiO2 talc. analysis shows decomposition absorption can effectively reduce thermal carbon erosion, gas produced chamber pressure form uniformly distributed nano-SiO2 protective layer. This solid-state high-efficiency organosilicon inhibitor an important guide for designing low-erosion gun
