Abstract

In this study, some improvements in the burning rate of hydroxyl-terminated polybutadiene (HTPB) based composite propellant was performed by introducing innovative fast burning energetic Al-Cu nanocomposite s (ACNs). By comparison with the reference composite propellant (based on nano-Al), the results showed the effectiveness of ACNs to improve the characteristics of HTPB composite propellant. The concentration effect of ANCs on the characteristics of HTPB propellant and the possibility of achieving further performance enhancement were studied. The main results have indicated that ACNs based propellants have achieved improvements in the combustion heat, burning rate, ignitability, and mechanical properties.
